MalariaSphere: a greenhouse-enclosed simulation of a natural Anopheles gambiae (Diptera: Culicidae) ecosystem in western Kenya. (1/829)

BACKGROUND: The development and implementation of innovative vector control strategies for malaria control in Africa requires in-depth ecological studies in contained semi-field environments. This particularly applies to the development and release of genetically-engineered vectors that are refractory to Plasmodium infection. Here we describe a modified greenhouse, designed to simulate a natural Anopheles gambiae Giles ecosystem, and the first successful trials to complete the life-cycle of this mosquito vector therein. METHODS: We constructed a local house, planted crops and created breeding sites to simulate the natural ecosystem of this vector in a screen-walled greenhouse, exposed to ambient climate conditions, in western Kenya. Using three different starting points for release (blood-fed females, virgin females and males, or eggs), we allowed subsequent stages of the life-cycle to proceed under close observation until one cycle was completed. RESULTS: Completion of the life-cycle was observed in all three trials, indicating that the major life-history behaviours (mating, sugar feeding, oviposition and host seeking) occurred successfully. CONCLUSION: The system described can be used to study the behavioural ecology of laboratory-reared and wild mosquitoes, and lends itself to contained studies on the stability of transgenes, fitness effects and phenotypic characteristics of genetically-engineered disease vectors. The extension of this approach, to enable continuous maintenance of successive and overlapping insect generations, should be prioritized. Semi-field systems represent a promising means to significantly enhance our understanding of the behavioural and evolutionary ecology of African malaria vectors and our ability to develop and evaluate innovative control strategies. With regard to genetically-modified mosquitoes, development of such systems is an essential prerequisite to full field releases.  (+info)

Early duplication and functional diversification of the opsin gene family in insects. (2/829)

Recent analysis of the complete mosquito Anopheles gambiae genome has revealed a far higher number of opsin genes than for either the Drosophila melanogaster genome or any other known insect. In particular, the analysis revealed an extraordinary opsin gene content expansion, whereby half are long wavelength-sensitive (LW) opsin gene duplicates. We analyzed this genomic data in relationship to other known insect opsins to estimate the relative timing of the LW opsin gene duplications and to identify "missing" paralogs in extant species. The inferred branching patterns of the LW opsin gene family phylogeny indicate at least one early gene duplication within insects before the emergence of the orders Orthoptera, Mantodea, Hymenoptera, Lepidoptera, and Diptera. These data predict the existence of one more LW opsin gene than is currently known from most insects. We tested this prediction by using a degenerate PCR strategy to screen the hymenopteran genome for novel LW opsin genes. We isolated two LW opsin gene sequences from each of five bee species, Bombus impatiens, B. terrestris, Diadasia afflicta, D. rinconis, and Osmia rufa, including 1.1 to 1.2 kb from a known (LW Rh1) and 1 kb from a new opsin gene (LW Rh2). Phylogenetic analysis suggests that the novel hymenopteran gene is orthologous to A. gambiae GPRop7, a gene that is apparently missing from D. melanogaster. Relative rate tests show that LW Rh2 is evolving at a slower rate than LW Rh1 and, therefore, may be a useful marker for higher-level hymenopteran systematics. Site-specific rate tests indicate the presence of several amino acid sites between LW Rh1 and LW Rh2 that have undergone shifts in selective constraints after duplication. These sites and others are discussed in relationship to putative structural and functional differences between the two genes.  (+info)

The genetics of inviability and male sterility in hybrids between Anopheles gambiae and An. arabiensis. (3/829)

Male hybrids between Anopheles gambiae and An. arabiensis suffer from hybrid sterility, and inviability effects are sometimes present as well. We examined the genetic basis of these reproductive barriers between the two species, using 21 microsatellite markers. Generally, recessive inviability effects were found on the X chromosome of gambiae that are incompatible with at least one factor on each arabiensis autosome. Inviability is complete when the gambiae and arabiensis inviability factors are hemi- or homozygous. Using a QTL mapping approach, regions that contribute to male hybrid sterility were also identified. The X chromosome has a disproportionately large effect on male hybrid sterility. Additionally, several moderate-to-large autosomal QTL were found in both species. The effect of these autosomal QTL is contingent upon the presence of an X chromosome from the other species. Substantial regions of the autosomes do not contribute markedly to male hybrid sterility. Finally, no evidence for epistatic interactions between conspecific sterility loci was found.  (+info)

Innate immunity in the malaria vector Anopheles gambiae: comparative and functional genomics. (4/829)

The resurgence of malaria is at least partly attributed to the absence of an effective vaccine, parasite resistance to antimalarial drugs and resistance to insecticides of the anopheline mosquito vectors. Novel strategies are needed to combat the disease on three fronts: protection (vaccines), prophylaxis/treatment (antimalarial drugs) and transmission blocking. The latter entails either killing the mosquitoes (insecticides), preventing mosquito biting (bednets and repellents), blocking parasite development in the vector (transmission blocking vaccines), genetic manipulation or chemical incapacitation of the vector. During the past decade, mosquito research has been energized by several breakthroughs, including the successful transformation of anopheline vectors, analysis of gene function by RNAi, genome-wide expression profiling using DNA microarrays and, most importantly, sequencing of the Anopheles gambiae genome. These breakthroughs helped unravel some of the mechanisms underlying the dynamic interactions between the parasite and the vector and shed light on the mosquito innate immune system as a set of potential targets to block parasite development. In this context, putative pattern recognition receptors of the mosquito that act as positive and negative regulators of parasite development have been identified recently. Characterizing these molecules and others of similar function, and identifying their ligands on the parasite surface, will provide clues on the nature of the interactions that define an efficient parasite-vector system and open up unprecedented opportunities to control the vectorial capacity of anopheline mosquitoes.  (+info)

A weather-driven model of malaria transmission. (5/829)

BACKGROUND: Climate is a major driving force behind malaria transmission and climate data are often used to account for the spatial, seasonal and interannual variation in malaria transmission. METHODS: This paper describes a mathematical-biological model of the parasite dynamics, comprising both the weather-dependent within-vector stages and the weather-independent within-host stages. RESULTS: Numerical evaluations of the model in both time and space show that it qualitatively reconstructs the prevalence of infection. CONCLUSION: A process-based modelling structure has been developed that may be suitable for the simulation of malaria forecasts based on seasonal weather forecasts.  (+info)

Structural and evolutionary analyses of the Ty3/gypsy group of LTR retrotransposons in the genome of Anopheles gambiae. (6/829)

The recent availability of the genome of Anopheles gambiae offers an extraordinary opportunity for comparative studies of the diversity of transposable elements (TEs) and their evolutionary dynamics between two related species, taking advantage of the existing information from Drosophila melanogaster. To this goal, we screened the genome of A. gambiae for elements belonging to the Ty3/gypsy group of long-terminal repeat (LTR) retrotransposons. The A. gambiae genome displays a rich diversity of LTR retrotransposons, clearly greater than D. melanogaster. We have characterized in detail 63 families, belonging to five of the nine main lineages of the Ty3/gypsy group. The Mag lineage is the most diverse and abundant, with more than 30 families. In sharp contrast with this finding, a single family belonging to this lineage has been found in D. melanogaster, here reported for the first time in the literature, most probably consisting of old inactive elements. The CsRn1 lineage is also abundant in A. gambiae but almost absent from D. melanogaster. Conversely, the Osvaldo lineage has been detected in Drosophila but not in Anopheles. Comparison of structural characteristics of different families led to the identification of several lineage-specific features such as the primer-binding site (PBS), the gag-pol translational recoding signal (TRS), which is extraordinarily diverse within the Ty3/gypsy retrotransposons of A. gambiae, or the presence/absence of specific amino acid motifs. Interestingly, some of these characteristics, although in general well conserved within lineages, may have evolved independently in particular branches of the phylogenetic tree. We also show evidence of recent activity for around 75% of the families. Nevertheless, almost all families contain a high proportion of degenerate members and solitary LTRs (solo LTRs), indicative of a lower turnover rate of retrotransposons belonging to the Ty3/gypsy group in A. gambiae than in D. melanogaster. Finally, we have detected significant overrepresentations of insertions on the X chromosome versus autosomes and of putatively active insertions on euchromatin versus heterochromatin.  (+info)

Invertebrate data predict an early emergence of vertebrate fibrillar collagen clades and an anti-incest model. (7/829)

Fibrillar collagens are involved in the formation of striated fibrils and are present from the first multicellular animals, sponges, to humans. Recently, a new evolutionary model for fibrillar collagens has been suggested (Boot-Handford, R. P., Tuckwell, D. S., Plumb, D. A., Farrington Rock, C., and Poulsom, R. (2003) J. Biol. Chem. 278, 31067-31077). In this model, a rare genomic event leads to the formation of the founder vertebrate fibrillar collagen gene prior to the early vertebrate genome duplications and the radiation of the vertebrate fibrillar collagen clades (A, B, and C). Here, we present the modular structure of the fibrillar collagen chains present in different invertebrates from the protostome Anopheles gambiae to the chordate Ciona intestinalis. From their modular structure and the use of a triple helix instead of C-propeptide sequences in phylogenetic analyses, we were able to show that the divergence of A and B clades arose early during evolution because alpha chains related to these clades are present in protostomes. Moreover, the event leading to the divergence of B and C clades from a founder gene arose before the appearance of vertebrates; altogether these data contradict the Boot-Handford model. Moreover, they indicate that all the key steps required for the formation of fibrils of variable structure and functionality arose step by step during invertebrate evolution.  (+info)

Distribution of ovary ecdysteroidogenic hormone I in the nervous system and gut of mosquitoes. (8/829)

Ovary ecdysteroidogenic hormone I (OEH I) is a gonadotropin in the female mosquito, Aedes aegypti. Whole-mount immunocytochemistry using OEH I antisera revealed an extensive distribution of immunostained cells in larvae and adults of this mosquito comparable to that observed in the African malaria mosquito, Anopheles gambiae. Medial neurosecretory cells were stained in brains of larvae and adult Ae. aegypti. In An gambiae the lateral neurosecretory cells were stained more often. In both species, immunostained axons from these cells extended out of the brain through the neurohemal organ associated with the aorta and branched extensively along the midgut. Immunostained endocrine cells were observed in larval and adult midguts of both species. In adults, abdominal metameric perivisceral organs were stained. Stained axons interconnected the perivisceral organs and neurosecretory cells in the abdominal ganglia. Episodic release of OEH I from these organs was evident in female Ae. aegypti, when staining disappeared at 12 hours after a blood meal and returned by 48 hours to levels observed before and up to 2 hours after the blood meal. Two sites were specifically stained only in An. gambiae: an axon net around the pyloric valve in the hindgut of larvae and adults and a ring of endocrine cells in the cardiac valve in the larval midgut. The markedly similar localizations of immunostained cells in larvae and adults of two distantly related species indicate that OEH I, or a homolog, is conserved within this group of Diptera and likely has stage- and sex-specific functions.  (+info)

However, progress towards identifying such cues is slow in part due to the lack of appropriate tools for investigating long-range attraction to putative oviposition substrates. This study aimed to develop a relatively easy-to-use bioassay system that can effectively analyse chemical attraction of gravid Anopheles gambiae sensu stricto. BG-Sentinel™ mosquito traps that use fans to dispense odourants were modified to contain aqueous substrates. Choice tests with two identical traps set in an 80 m2 screened semi-field system were used to analyse the catch efficacy of the traps and the effectiveness of the bioassay. A different batch of 200 gravid An. gambiae s.s. was released on every experimental night. Choices tested were (1) distilled versus distilled water (baseline) and (2) distilled water versus soil infusion. Further, comparisons were

Using Nylon Strips to Dispense Mosquito Attractants for Sampling the Malaria Vector Anopheles gambiae s.s.Using Nylon Strips to Dispense Mosquito Attractants for Sampling the Malaria Vector Anopheles gambiae s.s.
Synthetic versions of human derived kairomones can be used as baits when trapping host seeking mosquitoes. The effectiveness of these lures depends not only on their attractiveness to the mosquitoes but also on the medium from which they are dispensed.We report on the development and evaluation of nylon strips as a method of dispensing odorants attractive to the malaria vector, Anopheles gambiaes.s. (Giles).When a synthetic blend of attractants was dispensed using this method, signiÞcantly more mosquitoes were trapped than when two previous methods, open glass vials or low density polyethylene sachets were used. We conclude that the nylon strips are suitable for dispensing odorants in mosquito trapping operations and can be adopted for use in rural and remote areas. The nylon material required is cheap and widely available and the strips can be prepared without specialized equipment or ...

Anopheles gambiae sensu stricto, one of the principal vectors of malaria, has been divided into two subspecific groups, known as the M and S molecular forms. Recent studies suggest that the M form found in Cameroon is genetically distinct from the M form found in Mali and elsewhere in West Africa, suggesting further subdivision within that form. Chromosomal, microsatellite and geographic/ecological evidence are synthesized to identify sources of genetic polymorphism among chromosomal and molecular forms of the malaria vector Anopheles gambiae s.s. Cytogenetically the Forest M form is characterized as carrying the standard chromosome arrangement for six major chromosomal inversions, namely 2La, 2Rj, 2Rb, 2Rc, 2Rd, and 2Ru. Bayesian clustering analysis based on molecular form and chromosome inversion polymorphisms as well as microsatellites describe the Forest M form as a distinct population relative to the West African M form (Mopti-M form) and the S form. The Forest-M form was the most highly diverged

The long-lasting insecticidal nets (LLINs) and indoor residual spraying of insecticide (IRS) are major malaria vector control strategies in Mali. The success of control strategies depends on a better understanding of the status of malaria vectors with respect to the insecticides used. In this study we evaluate the level of resistance of Anopheles gambiae (sensu lato) to bendiocarb and the molecular mechanism that underlies it. Larvae of An. gambiae (s.l.) were collected from breeding habitats encountered in the three study sites and bioassayed with bendiocarb. The ace-1 target site substitution G119S was genotyped using a TaqMan assay. The three species of the An. gambiae complex in Mali, i.e. An. arabiensis, An. coluzzii and An. gambiae (s.s.) were found in sympatry in the three surveyed localities with different frequencies. We observed a resistance and suspicious resistance of the three species to bendiocarb with a mortality rate ranging from 37% to 86%. The allelic frequency of the G119S mutation

Studies on the roles of Anopheles gambiae and Anopheles funestus complexes in the transmission of Wuchereria bancrofti in Makurdi, Nigeria across four localities: High-level, Wurukum, North- bank and Wadata were undertaken from July, 2011 to June, 2012. 1,681 adult female mosquitoes were identified and dissected with the aid of standard keys and procedures to determine their incrimination rates with microfilariae of Wuchereria bancrofti. 1,040 (61.87%) of these were Anopheles gambiae sensu lato while 641 (38.13%) were Anopheles funestus. The results showed a significant difference ( between the mosquito species and their abundance. The overall microfilarial incrimination rate was 5.77% (97/1,681); Anopheles gambiae s.l. was more incriminated (3.57%) than Anopheles funestus (2.20%). The incrimination rates differed significantly ( between the two mosquito species surveyed. ANOVA also showed significant variations (P < 0.05) in the microfilarial incrimination rates across the localities and ...

Malaria is a serious threat to human life in sub-Saharan Africa, claiming many lives and causing the greatest morbidity as compared to other infectious diseases. Female Anopheles gambiae mosquito acts as the definitive host of Plasmodium protozoa, and allows sexual reproduction to take place in its gut. Infection rates may vary seasonally due to temperature changes, but this occurrence is not well studied in the Kenyan highlands. This study therefore aimed at investigating the seasonal variations in infection of Anopheles gambiae by Plasmodium oocysts and its implications on malaria prevalence in human beings. The study was conducted in three estates namely, Daraja mbili, Mwembe, and Maili Mbili which surround Kisii town in Nyanza province. Three villages in Keumbu location which is in the outskirts of Kisii town were also sampled to represent the rural population. Bi-weekly collection of mosquitoes during both wet and dry seasons was done for a period of 2 months in each season. Data were ...

Habitat discrimination by gravid Anopheles gambiae sensu lato - a push-pull systemHabitat discrimination by gravid Anopheles gambiae sensu lato - a push-pull system
Background: The non-random distribution of anopheline larvae in natural habitats suggests that gravid females discriminate between habitats of different quality. Whilst physical and chemical cues used by Culex and Aedes vector mosquitoes for selecting an oviposition site have been extensively studied, those for Anopheles remain poorly explored. Here the habitat selection by Anopheles gambiae sensu lato (s.l.), the principal African malaria vector, was investigated when presented with a choice of two infusions made from rabbit food pellets, or soil. Methods: Natural colonization and larval survival was evaluated in artificial ponds filled randomly with either infusion. Dual-choice, egg-count bioassays evaluated the responses of caged gravid females to (1) two- to six-day old infusions versus lake water; (2) autoclaved versus non-autoclaved soil infusions; and assessed (3) the olfactory memory of gravid females conditioned in pellet infusion as larvae. Results: Wild Anopheles exclusively colonized ...

The work included in this thesis arose from a long-standing interest in the possible use of genetic control for one of the most important malaria vectors in Africa, Anopheles gambiae sensu stricto. It was hoped that the genes involved in animal biting in the sibling species Anopheles quadriannulatus could be exploited by crossing with An. gambiae s. s. and using the fertile female hybrids for successive backcrosses to An. gambiae s. s.. It was envisaged that this method could be used in an attempt to produce a mosquito stock that is harmless to humans because it is zoophilic but with the genetic background of An. gambiae s. s. so that there would be no barriers to cross-mating in the wild. The innate host preference of mosquitoes can be determined in the laboratory using an olfactometer, or in the field using baits. Host-selection patterns in nature are often affected by external factors, which may or may not mask the host preference of the mosquito species in question (discussed in section ...

Various strategies that block malaria transmission from an infected human host to a female Anopheline mosquito that involve killing of the blood fed mosquito have been studied as a potential strategy to control malaria. These include the immunization of animal hosts with either whole homogenized blood fed mosquito midguts or their extracts. In 1939, William Trager first demonstrated anti-vector immunity by immunizing guinea pigs and rabbits with extracts of the tick Dermacentor variabilis. This immunological targeting of tick midgut antigens led to the commercial development of a vaccine against Boophilus microplus ticks licenced in 1985.This study investigated the mosquitocidal effects of an immune response elicited by immunization of BALB/c mice with a gene, Anopheles gambiae mucin 1 gene (AgMUC1 gene) alone or in combination with immunostimulatory cytokine genes GM-CSF or IL-12. The AgMUC1 genes were cloned from the midgut of blood fed female Anopheles gambiae mosquitoes. Four groups of ...

Anopheles gambiae sensu lato (s.l.) consists of several morphologically cryptic species throughout sub-Saharan Africa. In the Sahel region of Mali, this complex includes Anopheles arabiensis (Patton 1905) and A. gambiae sensu stricto (s.s.) (Giles 1902), which is further divided into the M and S molecular forms; all are important malaria vectors (Coluzzi et al., 1979; Collins et al., 2001; della Torre et al., 2001; Coluzzi et al., 2002; della Torre et al., 2002). Although they are morphologically indistinguishable and can occur in sympatry (Lindsay et al., 1998; Coluzzi et al., 2002; della Torre et al., 2002; della Torre et al., 2005; Simard et al., 2009), these cryptic species often differ in abundance according to season, local rainfall, latitude and larval site characteristics (Gimnig et al., 2001; Edillo et al., 2002; Koenraadt et al., 2004; Diabaté et al., 2005; Edillo et al., 2006; Diabaté et al., 2008; Costantini et al., 2009), and thus local differentiation may occur between these ...

Characterisation of Species and Diversity of Anopheles gambiae Keele ColonyCharacterisation of Species and Diversity of Anopheles gambiae Keele Colony
Anopheles gambiae sensu stricto was recently reclassified as two species, An. coluzzii and An. gambiae s.s., in wild-caught mosquitoes, on the basis of the molecular form, denoted M or S, of a marker on the X chromosome. The An. gambiae Keele line is an outbred laboratory colony strain that was developed around 12 years ago by crosses between mosquitoes from 4 existing An. gambiae colonies. Laboratory colonies of mosquitoes often have limited genetic diversity because of small starting populations (founder effect) and subsequent fluctuations in colony size. Here we describe the characterisation of the chromosomal form(s) present in the Keele line, and investigate the diversity present in the colony using microsatellite markers on chromosome 3. We also characterise the large 2La inversion on chromosome 2. The results indicate that only the M-form of the chromosome X marker is present in the Keele colony, which was unexpected given that 3 of the 4 parent colonies were probably S-form.

Status of insecticide resistance in malaria vectors in Kwale County, Coastal Kenya.Status of insecticide resistance in malaria vectors in Kwale County, Coastal Kenya.
BACKGROUND: The strategy for malaria vector control in the context of reducing malaria morbidity and mortality has been the scale-up of long-lasting insecticidal nets to universal coverage and indoor residual spraying. This has led to significant decline in malaria transmission. However, these vector control strategies rely on insecticides which are threatened by insecticide resistance. In this study the status of pyrethroid resistance in malaria vectors and its implication in malaria transmission at the Kenyan Coast was investigated. RESULTS: Using World Health Organization diagnostic bioassay, levels of phenotypic resistance to permethrin and deltamethrin was determined. Anopheles arabiensis showed high resistance to pyrethroids while Anopheles gambiae sensu stricto (s.s.) and Anopheles funestus showed low resistance and susceptibility, respectively. Anopheles gambiae sensu lato (s.l.) mosquitoes were further genotyped for L1014S and L1014F kdr mutation by real time PCR. An allele frequency ...

The Anopheles gambiae genome: next steps for malaria vector control | MetaThe Anopheles gambiae genome: next steps for malaria vector control | Meta
Malaria remains a major public health problem that is made worse by poor implementation of control measures, and by the spread of drug- and insecticide-resistant parasites and vectors, respectively. Availability of the Anopheles gambiae genome sequence will accelerate identification and exploitation of new target genes in this insect vector. This provides unique opportunities to improve on existing vector control tools and to generate new tools within a global partnership. However, significant capacity needs to be built for investigators in disease-endemic countries to exploit the genome data. When integrated with existing strategies, the new tools will form an effective package for selective vector control in an effort to prevent mortality and morbidity due to malaria. ...

The Population Dynamics of Anopheles gambiae Immature Stages and their Interaction with other Aquatic Fauna.The Population Dynamics of Anopheles gambiae Immature Stages and their Interaction with other Aquatic Fauna.
Anopheles gambiae sensu lato IS a major vector of malaria in western Kenya where environmental conditions are highly conducive for its survival and reproduction. Breeding mostly occurs in newly formed small and transient water bodies but as the habitats age they may become unattractive for breeding of the species. The aim of this study was to deduce some of the ecological implications of this strategy of early colonization of breeding sites by Anopheles gambiae s.l. Ten semi-natural habitats (5 small and 5 large) were studied longitudinally (sampled same population over time) for a period of 12 weeks with daily sampling of all larval and pupal stages and quantification of all other identifiable aquatic fauna. This was followed by a final census and retrieval of all inhabitants of each habitat. A new set of 10 habitats was investigated together with the old habitats using the same procedures for an additional period of 9 weeks. Larval cohorts lasting on average twelve days were easily noticeable ...

When natural larval habitats of An. gambiae s.l. dry up, their contribution towards the population dynamics of the adult stage is often neglected, since mass larval mortality is assumed to occur [9]. We found that eggs of An. gambiae s.s. hatched and that emerging larvae showed limited capability of reaching a nearby breeding site, when placed on damp soil. With this experiment we simulated a natural situation whereby eggs remain on damp soil when the water level drops or eggs are oviposited deliberately on damp soil after desiccation of the habitat [8, 10]. In addition, we found that larvae of An. gambiae s.s. survive for several days in sites that are drying up, depending on the larval stage.. Larvae that hatch from eggs on damp soil were able to reach a breeding site within a distance of 10 cm, albeit in low numbers. We induced hatching of the eggs by keeping the soil of our experimental sites damp by daily spraying of water, but during spraying we made sure that no water ran off or that a ...

Author Summary Malaria causes more than one million deaths every year, mostly among children in Sub-Saharan Africa. Anopheles mosquitoes are exclusive vectors of human malaria. Many malaria vectors belong to species complexes, and members within these complexes can vary significantly in their ecological adaptations and ability to transmit the parasite. To better understand evolution of epidemiologically important traits, we studied relationships among nonvector and vector species of the African Anopheles gambiae complex. We analyzed gene orders at genomic regions where evolutionary breaks of chromosomal inversions occurred in members of the complex and compared them with gene orders in species outside the complex. This approach allowed us to identify ancient and recent gene orders for three chromosomal inversions. Surprisingly, the more ancestral chromosomal arrangements were found in mosquito species that are vectors of human malaria, while the more derived arrangements were found in both nonvectors

To help improve the functional annotation of the Anopheles gambiae genome we have generated the MozAtlas, a unified catalogue of tissue-specific gene expression from a single mosquito strain. In Drosophila melanogaster, cataloguing tissue expression patterns has been useful, especially for inferring biological functions, since the majority of genes encoded in the genome are not ubiquitously expressed [19]. As with the fruit fly, Anopheles gene expression also exhibits substantial tissue specificity, with only a third of detectably expressed genes found in all tissues. Thus, the MozAtlas is a useful resource for better understanding the mosquito genome, providing direct evidence of genes with tissue restricted expression. Below we highlight the utility of MozAtlas for identifying classes of gene with tissue or sex-biased expression that may be exploited for vector control. Analysis of the MozAtlas also identifies gene expression features that are of interest from an evolutionary perspective, ...

Relative humidity drops to levels that are uncomfortable for mosquitoes at the end of the rainy season. In one village, Banizoumbou, water pools dried up and interrupted mosquito breeding shortly after the end of the rainy season. In this case, relative humidity had little effect on the mosquito population. However, in the other village, Zindarou, the relatively shallow water table led to water pools that persisted several months beyond the end of the rainy season. In this case, the decrease in mosquito survival due to relative humidity improved the models ability to reproduce the seasonal pattern of observed mosquito abundance ...

Temporal and spatial expression of serine protease genes in Anopheles gambiae. | IRIS Università degli Studi di PerugiaTemporal and spatial expression of serine protease genes in Anopheles gambiae. | IRIS Università degli Studi di Perugia
Serine proteases play a crucial role during the digestion of the blood meal in the mosquito gut. The isolation and the analysis of the genomic organisation of the corresponding genes may lead to the characterization of gut-specific, inducible promoters, suitable for the expression of anti-parasitic agents in the gut of transgenic mosquitoes. We report here on the identification of a trypsin and a chymotrypsin gene family of Anopheles gambiae. Following a blood meal, the transcription of all members of the two identified gene clusters, seven trypsin genes (Antryp1-7) and two chymotrypsin genes (Anchym1-2), is induced. Recombinant Antryp1 and Antryp2, expressed in E. coli, were both active in vitro against blood proteins. Moreover, mouse sera raised against Antryp1, Anchym1 and Anchym2 recognized the corresponding proteases among the proteins of a lysate prepared from dissected guts of An. gambiae mosquitoes.. ...

Here we present data on a cluster of 3 female LRT-specific serine protease genes suggested to be involved in post-mating processes in A. gambiae s.s. As already shown for other genes with different functions, the reconstruction of the 3 gene-trees shows that most species share alleles at all loci, as an effect of introgression and/or retention of ancestral polymorphisms, and that only A. merus and A. melas are placed in monophyletic assemblages (Figure 2). On the other hand, we found an unusually high substitution rate, which contributes mostly to an exceptionally high level of intra-specific polymorphisms, especially at nonsynonymous sites (Table 1). Moreover, while A. gambiae, A. arabiensis, and A. quadriannulatus do not differ for any fixed replacement, A. melas and A. merus diverge from the other species at all loci, showing a high number of fixed substitutions at both synonymous (7-9) and nonsynonymous (13-23) sites at locus AGAP005195..

The smell of success: Detection of nutritious blood meals by mosquitoesThe smell of success: Detection of nutritious blood meals by mosquitoes
Mosquitoes are important vectors of infectious diseases and successful transmission depends on the efficacy of host discrimination and blood uptake. This process is directed by the need for the mosquito to feed on those hosts that provide greatest fitness. We have preliminary evidence that mosquitoes can detect the quality of the blood meal based on the volatiles emitted from the human skin. The mosquito would thus be able to decide who is the best host for the development of her eggs. We will unravel one of the most important evolutionary mechanisms behind mosquito host choice by answering the hypothesis that malaria mosquitoes detect the quality of a host by its skin volatiles. Therefore, we will link someones attractiveness towards mosquitoes with his/her blood quality. Blood of 40 individuals will be analysed and fed to the malaria mosquito Anopheles gambiae in vivo and in vitro to determine differences in egg production. In addition, odour samples will be analysed and tested for ...

This is particularly significant for insects that undergo complete metamorphosis; larval mosquitoes must survive a freshwater habitat whereas adults are terrestrial, and mature females must maintain ion and fluid homeostasis after blood feeding. To investigate the physiological adaptations required for successful development to adulthood, we studied the Malpighian tubule transcriptome of Anopheles gambiae using Affymetrix arrays. We assessed transcription under several conditions; as third instar larvae, as adult males fed on sugar, as adult females fed on sugar, and adult females after a blood meal. In addition to providing the most detailed transcriptomic data to date on the Anopheles Malpighian tubules, the data provide unique information on the renal adaptations required for the switch from freshwater to terrestrial habitats, on gender differences, and on the contrast between nectar-feeding and haematophagy. We found clear differences ...

Both new and previously identified immune markers are expressed in adult mosquitoes, and thus are suited for monitoring induction by the malaria parasite. The markers show distinct and in some cases complex developmental expression profiles, which may reflect potential non‐defence‐related functions. Developmental and immune‐related processes often share the same components: examples are regulatory factors such as Dif, Dorsal and Relish in D.melanogaster (Dushay et al., 1996; Hoffmann et al., 1996), or effectors such as the Sarcophaga antibacterial defence proteins sapecin, sapecin B and cathepsin L (Natori and Kubo, 1996). Some of the A.gambiae infection‐responsive markers, GNBP, IGALE20 and ICHIT, encode adhesive motifs (Dimopoulos et al., 1996, 1997), and could be involved both in binding to microbial substances in defence and in the removal of apoptotic cells and tissue remodelling during development. NOS is known to have multiple functions in a variety of physiological processes. The ...

The original description of clathrin-coated vesicles as intracellular transport shuttles was based upon ultrastructural studies of developing mosquito oocytes (Roth and Porter, 1964). Vesicular profiles encased within a `bristle coat were very prominent at the cortex of Aedes aegypti oocytes several hours following a blood meal (Roth and Porter, 1964). The dramatic appearance of this bristle border, which we now know is composed of clathrin and associated coat proteins, reflects the fact that both A. aegypti and Anopheles gambiae mosquitoes are anautogenous - adult females must feed before egg production (Raikhel and Dhadialla, 1992). Thus, unlike Drosophila melanogaster, where a succession of progressively more mature egg chambers develop continuously (Drummond-Barbosa and Spradling, 2001; Schonbaum et al., 2000), egg maturation in newly eclosed A. aegypti or A. gambiae females developmentally arrests at a previtellogenic stage (Raikhel and Dhadialla, 1992; Roth and Porter, 1964).

IDEALS @ Illinois: Evolution of the Gr family of gustatory and odorant receptors in mosquitoesIDEALS @ Illinois: Evolution of the Gr family of gustatory and odorant receptors in mosquitoes
The ability to detect chemical information from the environment is of critical importance to insects, whose ecological and evolutionary boundaries typically revolve around taste and smell. Of the receptors involved in chemoperception, the gustatory receptor (Gr) protein family comprises most of the diversity in the insect chemoreceptor superfamily, including within it not only taste receptors, but select olfactory receptors as well. Manual annotation of the Gr family in the genome sequence of the yellow fever mosquito, Aedes aegypti Linnaeus, yielded a total of 114 potential proteins encoded by 79 genes. In the sequenced genome, 23 of these genes and protein isoforms are pseudogenic, leaving 91 putatively functional Grs. Comparison with the set of 76 Grs encoded by 52 genes in the distantly related Anopheles gambiae Giles mosquito revealed 13 new AgGrs encoded by eight genes. Phylogenetic analysis reveals the conservation of carbon dioxide, sugar and several orphan receptors in these two ...

Malaria is vectored by the mosquito Anopheles gambiae (Ag) in Sub-Saharan Africa and infects approximately 500 million people annually. The increasing prevalence of pyrethroid-resistant mosquitoes has amplified the need for development of new, selective mosquitocides for use on insecticide-treated nets. We have developed several phenyl-substituted N-methylcarbamates producing a high degree of selectivity for Anopheles gambiae acetylcholinesterase (AgAChE) over human AChE. Molecular models suggest alternate conformations (flexibility) of W84 and W431 (Ag numbering) at the hydrophobic subpocket of the AgAChE active site and poor flexibility within human AChE, allowing for the high selectivity of our novel carbamates. Initial selectivity data was obtained through screening of these insecticides while using ethanol as a solvent. Re-screening of these carbamates in the presence of 0.1% DMSO (v/v) resulted in antagonism of inhibition for AgAChE, thus reducing the AgAChE-selectivity by at least ...

The pyrethroid knockdown resistance gene (kdr) has become widespread in Anopheles gambiae in West Africa. A trial to test the continuing efficacy of insecticide-treated nets (ITN) and indoor residual spraying (IRS) was undertaken in experimental huts at 2 sites in Benin, the first where kdr is present at high frequency (Ladji), the second-where An. gambiae is susceptible (Malanville). Holes were made in the nets to mimic worn nets. At Malanville, 96% of susceptible An. gambiae were inhibited from blood-feeding, whereas at Ladji feeding was uninhibited by ITNs. The mortality rate of An. gambiae in ITN huts was 98% in Malanville but only 30% at Ladji. The efficacy of IRS was equally compromised. Mosquitoes at Ladji had higher oxidase and esterase activity than in a laboratory-susceptible strain, but this fact did not seem to contribute to resistance. Pyrethroid resistance in An. gambiae appears to threaten the future of ITN and IRS in Benin ...

Vector control is a major component of the malaria control strategy. The increasing spread of insecticide resistance has encouraged the development of new tools such as genetic control which use releases of modified male mosquitoes. The use of male mosquitoes as part of a control strategy requires an improved understanding of male mosquito biology, including the factors influencing their survival and dispersal, as well as the ability to accurately estimate the size of a target mosquito population. This study was designed to determine the seasonal variation in population size via repeated mark-release-recapture experiments and to estimate the survival and dispersal of male mosquitoes of the Anopheles gambiae complex in a small west African village ...

Appropriate monitoring of vector insecticide susceptibility is required to provide the rationale for optimal insecticide selection in vector control programs. In order to assess the influence of mosquito age on susceptibility to various insecticides, field-collected larvae of An. gambiae s.l. from Tiassalé were reared to adults. Females aged 1, 2, 3, 5 and 10 days were exposed to 5 insecticides (deltamethrin, permethrin, DDT, malathion and propoxur) using WHO susceptibility test kits. Outcome measures included the LT50 (exposure time required to achieve 50% knockdown), the RR (resistance ratio, i.e. a calculation of how much more resistant the wild population is compared with a standard susceptible strain) and the mortality rate following 1 hour exposure, for each insecticide and each mosquito age group. There was a positive correlation between the rate of knockdown and mortality for all the age groups and for all insecticides tested. For deltamethrin, the RR50 was highest for 2 day old and lowest for

Radical remodeling of the Y chromosome in a recent radiation of malaria mosquitoes. | VectorBaseRadical remodeling of the Y chromosome in a recent radiation of malaria mosquitoes. | VectorBase
Y chromosomes control essential male functions in many species, including sex determination and fertility. However, because of obstacles posed by repeat-rich heterochromatin, knowledge of Y chromosome sequences is limited to a handful of model organisms, constraining our understanding of Y biology across the tree of life. Here, we leverage long single-molecule sequencing to determine the content and structure of the nonrecombining Y chromosome of the primary African malaria mosquito, Anopheles gambiae We find that the An. gambiae Y consists almost entirely of a few massively amplified, tandemly arrayed repeats, some of which can recombine with similar repeats on the X chromosome. Sex-specific genome resequencing in a recent species radiation, the An. gambiae complex, revealed rapid sequence turnover within An. gambiae and among species. Exploiting 52 sex-specific An. gambiae RNA-Seq datasets representing all developmental stages, we identified a small repertoire of Y-linked genes that lack X ...

Here, we use quantitative trait locus (QTL) mapping to investigate the genetic architecture of osmoregulation in Anopheles mosquitoes, vectors of human malaria. We analyzed 1134 backcross progeny from a cross between the obligate FW species An. coluzzii, and its closely related euryhaline sibling species An. merus. Tests of 2387 markers with Bayesian interval mapping and machine learning (random forests) yielded six genomic regions associated with SW tolerance. Overlap in QTL regions from both approaches enhances confidence in QTL identification. ...

Anopheles funestus Giles is a major malaria vector in Africa belonging to a group of species with morphologically similar characteristics. Morphological identification of members of the A. funestus group is difficult because of overlap of distinguishing characteristics in adult or immature stages as well as the necessity to rear isofemale lines to examine larval and egg characters. A rapid rDNA polymerase chain reaction (PCR) method has been developed to accurately identify five members of the A. funestus group. This PCR is based on species-specific primers in the ITS2 region on the rDNA to identify A. funestus (approximately 505bp), Anopheles vaneedeni Gillies and Coetzee (approximately 587bp), Anopheles rivulorum Leeson (approximately 411bp), Anopheles leesoni Evans (approximately 146bp), and Anopheles parensis Gillies (approximately 252bp).

Adaptive introgression can provide novel genetic variation to fuel rapid evolutionary responses, though it may be counterbalanced by potential for detrimental disruption of the recipient genomic background. We examine the extent and impact of recent introgression of a strongly selected insecticide-resistance mutation (Vgsc-1014F) located within one of two exceptionally large genomic islands of divergence separating the Anopheles gambiae species pair. Here we show that transfer of the Vgsc mutation results in homogenization of the entire genomic island region (~1.5% of the genome) between species. Despite this massive disruption, introgression is clearly adaptive with a dramatic rise in frequency of Vgsc-1014F and no discernable impact on subsequent reproductive isolation between species. Our results show (1) how resilience of genomes to massive introgression can permit rapid adaptive response to anthropogenic selection and (2) that even extreme prominence of genomic islands of divergence can be an

SUMMARY Malaria kills millions of people every year, yet there has been little progress in controlling this disease. For transmission to occur, the malaria parasite has to complete a complex developmental cycle in the mosquito. The mosquito is therefore a potential weak link in malaria transmission, and generating mosquito populations that are refractory to the parasite is a potential means of controlling the disease. There has been considerable progress over the last decade towards developing the tools for creating a refractory mosquito. Accomplishments include germline transformation of several important mosquito vectors, the completed genomes of the mosquito Anopheles gambiae and the malaria parasite Plasmodium falciparum, and the identification of promoters and effector genes that confer resistance in the mosquito. These tools have provided researchers with the ability to engineer a refractory mosquito vector, but there are fundamental gaps in our knowledge of how to transfer this technology safely

The Anopheles gambiae peptidoglycan recognition protein (PGRP) gene family consists of 7 genes with 13 PGRP domains. We analyze the role of these genes in the mosquito immune defense to bacteria and the malaria parasite Plasmodium berghei. We have previously shown that the NF-κB transcription factor REL2 is involved in defense against both types of bacteria and malaria parasites [1]. IMD is only responsible for the reaction against Gram-positive bacteria and Plasmodium. Our data suggests significant divergence as well as many similarities of immune signaling between Anopheles gambiae and the fruit fly Drosophila melanogaster. The differences most likely reflect the different lifestyles of the two insects and, consequently, different infectious agents that the two insects encounter during their lifetimes. In mosquitoes, one of these agents is the malaria parasite Plasmodium ...

Background Little is known about how malaria mosquitoes locate oviposition sites in nature. Such knowledge is important to help devise monitoring and control measures that could be used to target gravid females. This study set out to develop a suite of tools that can be used to study the attraction of gravid Anopheles gambiae s.s. towards visual or olfactory cues associated with aquatic habitats. Methods Firstly, the study developed and assessed methods for using electrocuting nets to analyse the orientation of gravid females towards an aquatic habitat. Electric nets (1m high × 0.5m wide) were powered by a 12V battery via a spark box. High and low energy settings were compared for mosquito electrocution and a collection device developed to retain electrocuted mosquitoes when falling to the ground. Secondly, a range of sticky materials and a detergent were tested to quantify if and where gravid females land to lay their eggs, by treating the edge of the ponds and the water surface.

Dan Meyrowitsch explains that the 99 % fall in the malaria mosquito population during the end of the 1990s seems to be connected to a fall in precipitation. This may be due to global climate changes.. - From 2003 to 2009 the volume of precipitation was more stable, but the rain was more chaotic and fell outside the rainy season. And this may have disturbed the natural cycle of mosquito development, he says.. -Of course it is great that the number of malaria-related fatalities among children has fallen drastically in the last five or six years, but we need to know why!. Since the researchers can discount mosquito nets, the question is whether the mosquitoes have succumbed to disease, or communities have been using pesticides, or whether the fall is due to the chaotic new precipitation patterns.. - Unless we find the answer we will not be able to predict when the malaria mosquitoes will come back, and that could rapidly prove critical, Dan Meyrowitsch explains.. ...

This study set out to develop a suite of tools that can be used to study the attraction of gravid Anopheles gambiae s.s. towards visual or olfactory cues associated with aquatic habitats. Methods: Firstly, the study developed and assessed methods for using electrocuting nets to analyse the orientation of gravid females towards an aquatic habitat. Electric nets (1m high x 0.5m wide) were powered by a 12V battery via a spark box. High and low energy settings were compared for mosquito electrocution and a collection device developed to retain electrocuted mosquitoes when falling to the ground. Secondly, a range of sticky materials and a detergent were tested to quantify if and where gravid females land to lay their eggs, by treating the edge of the ponds and the water surface. A randomized ...

Deciphering the molecular mechanisms affecting ookinete survival in the mosquito. Vector immune responses are responsible, at least in part, for the major parasite losses during parasite development. We now know, largely from functional studies in our laboratory, that even what is called susceptible A. gambiae mosquitoes effectively kill a large number of invading ookinetes (80 %), which are most probably cleared by lysis. Two genes, LRIM1 and TEP1, were shown to be strongly involved in ookinete killing in susceptible mosquitoes (G3 strain). LRIM1 expression was strongly induced in mosquito midguts and carcasses in response to the invasion of the mosquito midgut epithelium by Plasmodium ookinetes. The transient KD of LRIM1 in susceptible mosquitoes by RNAi resulted in approximately a four-fold increase in the number of parasites that successfully develop in the mosquito midguts, suggesting that LRIM1 is involved in parasite killing. TEP1 is as a bona fide pattern-recognition receptor that ...

New Findings May Help Control Disease-Carrying Mosquitoes - MosquitoTraps.bizNew Findings May Help Control Disease-Carrying Mosquitoes - MosquitoTraps.biz
Mosquito sperm have a sense of smell - a surprising finding that could one day help control disease-carrying mosquitoes, researchers say.. Mosquitoes use scent-detecting molecules known as odorant receptors in their antennae. These sensors help mosquitoes sniff out sources of blood as part of their sense of smell, technically known as olfaction.. Now, researchers have discovered mosquitoes have these same molecules in their sperm. Scientists analyzed the mosquito species Anopheles gambiae, one of the most common carriers of malaria. They found odorant receptors on the whip like tails of the mosquitoes sperm. These molecules help to spur the beating of the tails, and thus help control the movement of the sperm, the researchers said. read more. ...

A Mosquito Dna Transposon Agh1: Structure, Evolution and Evidence of ActivityA Mosquito Dna Transposon Agh1: Structure, Evolution and Evidence of Activity
Transposable elements (TEs) are mobile genetic elements. They are a significant component of many eukaryotic genomes. They are involved in chromosomal rearrangement by serving as substrates for homologous recombination, in creating new genes through a process of TE domestication, and in modifying and shuffling existing genes by transducing neighboring sequences (Lander et al., 2001). Therefore, both active and inactive TEs are potentially potent agents for genomic change (Kidwell and Lisch, 2001, 2002; Rizzon et al., 2002; Petrov et al., 2003). In the meantime, active TEs are being explored as useful tools for genetic transformation and possible gene drive mechanisms to deliver genes in natural populations (Ashburner et al.,1998; Alphey et al.,2002; Handler and OBrochta, 2004). My thesis project focuses on AGH1, a novel DNA-mediated TE in Anopheles gambiae and related mosquitoes. I have studied its genomic structure, insertion polymorphism, evolution, and transposition activity. As part of ...

The Ubiquitous Protein Domain EAL Is a Cyclic Diguanylate-Specific Phosphodiesterase: Enzymatically Active and Inactive EAL...The Ubiquitous Protein Domain EAL Is a Cyclic Diguanylate-Specific Phosphodiesterase: Enzymatically Active and Inactive EAL...
The approximately 250-amino-acid protein domain EAL (www.sanger.ac.uk/Software/Pfam), also referred to as domain of unknown function 2 or DUF2 (http://smart.embl-heidelberg.de), is conserved in the Bacteria. The domain name originates from one of the most conserved amino acid signature motifs, EAL (Glu-Ala-Leu). EAL is encoded by most sequenced genomes in all branches of the bacterial phylogenetic tree, which implies that EAL-containing proteins play important roles in Bacteria (8, 9). This domain is not encoded in the genomes of Archaea or Eukarya, except for two putative proteins of Anopheles gambiae, which probably originated from bacterial contamination (19). EAL is often linked to sensory and/or output (signal transduction) domains and is, in fact, one of the most ubiquitous bacterial signal transduction domains whose biochemical activity has not been characterized yet (8, 9). In many proteins, EAL is located C terminal of the approximately 170-amino-acid GGDEF domain (also known as DUF1). ...

Vertical and Horizontal Transmission in Paratransgenic Anopheles Mosquitoes : IGTRCNVertical and Horizontal Transmission in Paratransgenic Anopheles Mosquitoes : IGTRCN
The authors demonstrate that these marked symbionts can then be transmitted to their progeny through mating and to non-sibling larvae by horizontal transmission via the water in which the animals are living.. The authors created a number of strains of AS1 containing a collection of anti Plasmodium effectors either singly or in combination and show that these have significant impacts on the intensity of midgut infections.. This is a very interesting paper that seems to bring the promise of paratransgenic approaches closer to fruition as tools for combating vector borne diseases.. An interesting feature of this approach is that it can be used to simultaneously reduce the vectoral capacity of multiple anopheles species in an environment whereas transgenic approaches would require solving the problems of creating transgenics from these other species. Not necessarily and easy task.. The widespread presence of these genetically modified bacteria in water sources will elicit questions related to risk ...

Genetically engineered mosquitoes could be vital weapon against malaria - NextBillionGenetically engineered mosquitoes could be vital weapon against malaria - NextBillion
Wednesday, April 23, 2014. 627,000 deaths per year: thats a good figure. Malaria, the deadly illness caused by infected mosquitoes, is on the retreat, thanks to medical treatments that have reduced mortality rates by 42% since 2000. Among African children, the mortality rate has dropped even more: 54%. Even so, one African child dies of malaria every minute, according to the World Health Organisation.. Its not that NGOs and aid organisations dont try hard enough to prevent the parasite-infected mosquitoes from biting humans: its just that keeping every one of the tiny insects away with nets and insecticides is very hard work.. What if all that mosquito-chasing wasnt necessary? What if the insects killed themselves? Thats the idea behind Oxitec, an Oxford-based biotech company. It breeds sterile male mosquitoes for release in affected areas. As male mosquitoes always do, theyll find the females and mate with them - but because theyre sterile, the offspring will die. Were using ...

Mosquitoes: Etymology, History, and Habits | Wyzant ResourcesMosquitoes: Etymology, History, and Habits | Wyzant Resources
And as I think, once more I m bitten. -Dick Emmons Male mosquitoes drink only sugary fluids such as flower nectar. Both in the wild and in the laboratory, mosquitoes will visit certain flowers and will feed on fruit placed in their cage. Since they vigorously probe the flowers of some plants and can distinguish between different types of sugars, mosquitoes play a role in the pollination of certain plants. The females will also drink sugary fluids, but when hungry females are given a choice between sugar water and blood, they will always choose blood. If males are offered the same choice, they will always drink the sugar water. Since male mosquitoes do not suck blood, they also do not transmit diseases. Like the males of many other insect families, they are important for just one reason, and then they become superfluous. The female usually needs to mate just once in her life. She stores sperm in her body and fertilizes her eggs at the moment when she lays them. Shortly before or after mating, she ...

  • Malaria vector mosquitoes belonging to the Anopheles gambiae complex were studied in four hamlets in The Gambia. (semanticscholar.org)
Odorant receptor1
  • Here we functionally characterize the Anopheles gambiae odorant receptor (AgOr) repertoire. (nature.com)
Proteome1
  • Champion M.M., Sheppard A.D., Rund S.S.C., Freed S.A., O'Tousa J.E. and Duffield G.E. (2015) Qualitative and quantitative proteomics methods for the analysis of the Anopheles gambiae mosquito proteome. (vectorbase.org)
Chromosomes1
  • Dissections of the salivary gland of the Anopheles yielded chromosomes which spread successfully as expected. (scirj.org)
Malaria vector control1
  • The development of insecticide resistance in anopheles mosquitoes is a major threat for malaria vector control. (biomedcentral.com)
Anthropophilic1
  • Among other things, the author investigated the potentially very important problem: are there two races of gambiae -zoophilic and anthropophilic? (ajtmh.org)
Mechanisms2
  • We describe an in vivo model for investigation of detoxification mechanisms of the mosquito Anopheles gambiae, important for the development of malaria control programmes. (lstmed.ac.uk)
  • Studies on mechanisms of resistance and factors selecting each type of mechanism in Anopheles gambiae from south western Nigeria and Kwara State / by Djouaka-Folefack, Jean Rousseau. (who.int)
Experiments1
