Can anything be done to maintain the effectiveness of pyrethroid-impregnated bednets against malaria vectors? (1/724)

Pyrethroid-treated bednets are the most promising available method of controlling malaria in the tropical world. Every effort should be made to find methods of responding to, or preventing, the emergence of pyrethroid resistance in the Anopheles vectors. Some cases of such resistance are known, notably in An. gambiae in West Africa where the kdr type of resistance has been selected, probably because of the use of pyrethroids on cotton. Because pyrethroids are irritant to mosquitoes, laboratory studies on the impact of, and selection for, resistance need to be conducted with free-flying mosquitoes in conditions that are as realistic as possible. Such studies are beginning to suggest that, although there is cross-resistance to all pyrethroids, some treatments are less likely to select for resistance than others are. Organophosphate, carbamate and phenyl pyrazole insecticides have been tested as alternative treatments for nets or curtains. Attempts have been made to mix an insect growth regulator and a pyrethroid on netting to sterilize pyrethroid-resistant mosquitoes that are not killed after contact with the netting. There seems to be no easy solution to the problem of pyrethroid resistance management, but further research is urgently needed.  (+info)

Altered properties of neuronal sodium channels associated with genetic resistance to pyrethroids. (2/724)

Genetic resistance to pyrethroid insecticides involves nervous system insensitivity linked to regulatory and structural genes of voltage-sensitive sodium channels. We examined the properties and relative density of sodium channels in central neurons of susceptible and pyrethroid-resistant (Pyr-R) insects that were homozygous for the amino acid substitution V421M in the I-S6 transmembrane segment. Pyr-R sodium channels show approximately 21-fold lower sensitivity to the synthetic pyrethroid permethrin and a approximately 2-fold increased sensitivity to the alpha-scorpion toxin LqhalphaIT. Pyr-R channels also exhibit altered gating properties, including a approximately 13 mV positive shift in voltage-dependent activation and approximately 7 mV positive shift in steady-state inactivation. Consistent with these changes in gating behavior, Pyr-R central neurons are less excitable, as evidenced by an approximately 11 mV elevation of action potential threshold. No differences in sodium channel density are evident. The altered properties of Pyr-R sodium channels provide a plausible molecular basis for nervous system insensitivity associated with pyrethroid resistance.  (+info)

Estrogenic potential of certain pyrethroid compounds in the MCF-7 human breast carcinoma cell line. (3/724)

Estrogens, whether natural or synthetic, clearly influence reproductive development, senescence, and carcinogenesis. Pyrethroid insecticides are now the most widely used agents for indoor pest control, providing potential for human exposure. Using the MCF-7 human breast carcinoma cell line, we studied the estrogenic potential of several synthetic pyrethroid compounds in vitro using pS2 mRNA levels as the end point. We tested sumithrin, fenvalerate, d-trans allethrin, and permethrin. Nanomolar concentrations of either sumithrin or fenvalerate were sufficient to increase pS2 expression slightly above basal levels. At micromolar concentrations, these two pyrethroid compounds induced pS2 expression to levels comparable to those elicited by 10 nM 17ss-estradiol (fivefold). The estrogenic activity of sumithrin was abolished with co-treatment with an antiestrogen (ICI 164,384), whereas estrogenic activity of fenvalerate was not significantly diminished with antiestrogen co-treatment. In addition, both sumithrin and fenvalerate were able to induce cell proliferation of MCF-7 cells in a dose-response fashion. Neither permethrin nor d-trans allethrin affected pS2 expression. Permethrin had a noticeable effect on cell proliferation at 100 microM, whereas d-trans allethrin slightly induced MCF-7 cell proliferation at 10 microM, but was toxic at higher concentrations. Overall, our studies imply that each pyrethroid compound is unique in its ability to influence several cellular pathways. These findings suggest that pyrethroids should be considered to be hormone disruptors, and their potential to affect endocrine function in humans and wildlife should be investigated.  (+info)

The impact of charging for insecticide on the Gambian National Impregnated Bednet Programme. (4/724)

During the second year of the Gambian National Impregnated Bednet Programme (NIBP) charges for insecticide ($0.50 per net) were introduced into the half of the primary health care villages in the country where insecticide have been provided free of charge the previous year. Free insecticide was provided in the remaining villages that had acted as controls during the previous year. In villages where insecticide was provided free, 77% of nets were treated with insecticide. In contrast, in villages where charges were made coverage was only 14%. During the first year of the NIBP, mortality in children was significantly lower in villages where insecticide was provided free than in the control villages. Introduction of a charge for insecticide into the first group of villages and the provision of free insecticide in the latter abolished this difference. The cash income of rural Gambians is very limited and payment of even $2-3 for insecticide treatment for all the bednets in a household represents a substantial outlay. Further education on the benefits of treatment of nets and/or the provision of cheaper insecticide will be required before the full benefits of this powerful new malaria control measure can be fully realised in the Gambia.  (+info)

Yeast calcineurin regulates nuclear localization of the Crz1p transcription factor through dephosphorylation. (5/724)

Calcineurin, a Ca2+/calmodulin dependent protein phosphatase, regulates Ca2+-dependent processes in a wide variety of cells. In the yeast, Saccharomyces cerevisiae, calcineurin effects Ca2+-dependent changes in gene expression through regulation of the Crz1p transcription factor. We show here that calcineurin dephosphorylates Crz1p and that this results in translocation of Crz1p to the nucleus. We identify a region of Crz1p that is required for calcineurin-dependent regulation of its phosphorylation, localization, and activity, and show that this region has significant sequence simlarity to a portion of NF-AT, a family of mammalian transcription factors whose localization is also regulated by calcineurin. Thus, the mechanism of Ca2+/calcineurin-dependent signaling shows remarkable conservation between yeast and mammalian cells.  (+info)

Control of malaria vectors: cost analysis in a province of northern Vietnam. (6/724)

The cost of permethrin-treated bednets (50% EC; 0.2 g/m2, 2 rounds per year) was compared to the cost of residual spraying with lambdacyhalothrin 10% WP (0.03 g/m2, once yearly) in Hoa Binh, a mountainous province in northern Vietnam. Calculations of the amounts of insecticides needed were based on national guidelines, on data from a cross-sectional survey and on district activity reports. The actual cost of insecticide required per person per year was lower for impregnation (US$ 0.26) than for spraying (US$ 0.36), but the difference was smaller than expected. The total cost for impregnated bednets per person per year amounted to US$ 0.90 compared to USS 0.47 for spraying. The determining factor was the cost of the net, amounting to US$ 0.58 per person per year, assuming a 5-year life of the net. Other material (excluding nets), labour and transport combined, accounted for only 17% of the impregnation cost and 23% of spraying expenses. However, for the National Malaria Control Programme of Vietnam, the cost per person per year for impregnated bednets amounted to US$ 0.32 only, because the vast majority of nets are bought by the population. For spraying, the programme had to bear the entire cost.  (+info)

Status of pyrethroid resistance in Anopheles gambiae sensu lato. (7/724)

The present study confirms the presence of pyrethroid resistance among Anopheles gambiae s.l mosquitos in Cote d'Ivoire and reports the observation of such resistance in two other countries in West Africa (Benin and Burkina Faso). Malaria vector populations from Cameroon (Central Africa), Senegal (West Africa) and Botswana (southern Africa) were found to be susceptible to pyrethroids. In the most resistant mosquito populations, resistance to permethrin was associated with reduced mortality, not only with respect to this compound but also towards deltamethrin. Moreover, a significant increase in knockdown time was observed in some mosquito populations before any decrease in mortality, suggesting that knockdown time could be a good indicator for the early detection of pyrethroid resistance. In view of the current extension of such resistance, there is an urgent need to set up a network in Africa to evaluate its development. It is also vital that the impact of this resistance on pyrethroid-impregnated bednets be assessed.  (+info)

A new strategy for treating nets. Part 1: formulation and dosage. (8/724)

The conventional dosages of pyrethroid insecticides on mosquito nets assume that nets will be retreated at 6-12 month intervals. However, dosage should be related to washing of nets; if nets are only washed once or twice a year, their dosage requirements will be different to those which are washed fortnightly. A 'low-dose, frequent-wash' retreatment system might be technically more appropriate and more affordable where nets are washed frequently, as they are in Dar es Salaam. Moreover, for use as a domestic insecticide, water-based formulations of pyrethroid are preferable to the more commonly used emulsifiable concentrates (ECs). This paper reports laboratory evaluations of three formulations (ECs, Flowable, CS) of three pyrethroids (deltamethrin, lambdacyhalothrin, permethrin). Insecticidal activity was tested using serial bioassays at a range of dosages using Anopheles gambiae. The water-based formulations were no less effective than the ECs, even at the lowest dosages. Nets treated with 3 mg/m2 and then repeatedly washed and retreated after each wash with either 3 mg/m2 or 1 mg/m2 were subjected to gas chromatography analysis. This showed that the amounts of pyrethroid in the nets accumulated rapidly over the first few wash-retreatment cycles and then remained fairly stable over subsequent cycles. These nets gave consistently high bioassay mortalities throughout the experiment, while the mortality declined rapidly after several washes with the nets that were treated at 3 mg/m2 but not retreated. Experimental huts were used to compare the effectiveness of these 2 net retreatment regimes and nets which were not retreated. All nets caused high mortality rates amongst Anopheles females, but had negligible effects on culicines; either in killing them or in preventing feeding. Therefore use of a high 'loading' dose for initial treatment with lower 'maintenance' doses for retreatment may be preferable to ensure that net users promptly perceive the benefits of the insecticide against culicines.  (+info)

EPA reviewed 273 tolerances for a group of ten synthetic pyrethroid insecticides in the largest pesticide tolerance assessment since the inception of the Food Quality Protection Act (FQPA) of 1996. The action included establishing final tolerances for 47 time-limited tolerances which were due to expire on Nov. 15. The tolerances were time-limited because of the potential risk to aquatic invertebrates and fish posed by the pesticides. The class of ten insecticides include bifenthrin, cyfluthrin, cypermethrin, zeta-cypermethrin, deltamethrin, esfenvalerate, fenpropathrin, lambda-cyhalothrin, tralomethrin, and tefluthrin. New FQPA-mandated regulations required EPA to perform complete assessments of all tolerances before renewing the chemicals conditional registrations, and to include assessments of the aggregate risks from dietary exposure, exposure in drinking water, and exposure through residential use, for which some of these insecticides are registered. Major agricultural crop uses include ...
Mosquito resistance to the pyrethroid insecticides used to treat bednets threatens the sustainability of malaria control in sub-Saharan Africa. While the impact of target site insensitivity alleles is being widely discussed the implications of insecticide detoxification - though equally important - remains elusive. The successful development of new tools for malaria intervention and management requires a comprehensive understanding of insecticide resistance, including metabolic resistance mechanisms. Although three enzyme families (cytochrome P450s, glutathione S-transferases and carboxylesterases) have been widely associated with insecticide detoxification the role of individual enzymes is largely unknown. Here, constitutive expression patterns of genes putatively involved in conferring pyrethroid resistance was investigated in a recently colonised pyrethroid resistant Anopheles gambiae strain from Odumasy, Southern Ghana. RNA from the resistant strain and a standard laboratory susceptible strain, of

N2 - It has been demonstrated previously that select Type II pyrethroids are potent proconvulsants in the rat and that the proconvulsant actions of deltamethrin are blocked by administration of PK 11195, an antagonist of the peripheral-type benzodiazepine receptor (PTBR). The present investigation has extended these findings to include various Type I pyrethroids as proconvulsants. Additionally, the proconvulsant activity of cismethrin was reversed by administration of PK 11195. Pyrethroid displacement of specific [3H]Ro5-4864 binding to rat brain membranes was investigated to further define the interaction of pyrethroids with the PTBR. Both Type I and Type II pyrethroids potently inhibited [3H]Ro5-4864 binding with affinities ranging from nanomolar to micromolar. The ED50 values for the proconvulsant ...
ABSTRACT. Alpha-cypermethrin (α-CYP) a synthetic pyrethroid (type-II) pesticide. Pyrethroid insecticides have been used in agricultural and home formulations for more than 30 years. Despite their extensive worldwide use, there are relatively few reports of the kinetic profile. Dissolved in alcohol was given to male albino rat for 24hr individual groups at 5, 10, 25 and 50mM dose for each group. The animals were sacrificed after 24hr duration. Biochemical studies were observed in testis. Increased the activity of alkaline phosphatase(ALP) at 24hr duration, while decreased acid phosphatase(ACP) at respective duration. Therefore low doses of alpha-cypermethrin altered testicular biomarker enzyme activities. This may interfere in the functioning of the reproductive system of albino rat.. Keywords: Alpha-cypermethrin; Albino rats; ALP; ACP. ...
Malaria control today is threatened by widespread insecticide resistance in vector populations. The World Health Organization (WHO) recommends the use of a mixture of unrelated insecticides for indoor residual spraying (IRS) and long-lasting insecticidal nets (LNs) or as a combination of interventions for improved vector control and insecticide resistance management. Studies investigating the efficacy of these different strategies are necessary. The efficacy of Interceptor® G2 LN, a newly developed LN treated with a mixture of chlorfenapyr (a pyrrole) and alpha-cypermethrin (a pyrethroid), was compared to a combined chlorfenapyr IRS and Interceptor® LN (a standard alpha-cypermethrin LN) intervention in experimental huts in Cove Southern Benin, against wild, free-flying, pyrethroid-resistant Anopheles gambiae s.l. A direct comparison was also made with a pyrethroid-only net (Interceptor® LN) alone and chorfenapyr IRS alone. WHO resistance bioassays performed during the trial demonstrated a pyrethroid
Cypermethrin is very toxic to cats which cannot tolerate the therapeutic doses for dogs.[7] This is associated with UGT1A6 deficiency in cats, the enzyme responsible for metabolizing cypermethrin. As a consequence, cypermethrin remains much longer in the cats organs than in dogs or other mammals and can be fatal in large doses. In male rats cypermethrin was shown to exhibit a toxic effect on the reproductive system. After 15 days of continual dosing, both androgen receptor levels and serum testosterone levels were significantly reduced. These data suggested that cypermethrin can induce impairments of the structure of seminiferous tubules and spermatogenesis in male rats at high doses.[8] Long-term exposure to cypermethrin during adulthood is found to induce dopaminergic neurodegeneration in rats, and postnatal exposure enhances the susceptibility of animals to dopaminergic neurodegeneration if rechallenged during adulthood.[9] If exposed to cypermethrin during pregnancy, rats give birth to ...
Pyrethroid insecticides are known to modify neuronal sodium channels, inducing persistent, steady-state sodium current at depolarized membrane potentials. Cardiac myocytes are also rich in sodium channels but comparatively little is known about the effect of pyrethroids on the heart, or on the cardiac sodium channel isoform. In the present study therefore, we determined the actions of type I and type II pyrethroids against rat and guinea pig ventricular myocytes under current and voltage clamp, and on isolated perfused rat hearts. In myocytes, tefluthrin (type I) and fenpropathrin and alpha-cypermethrin (type II) prolonged action potentials and evoked afterdepolarizations. The time course of sodium current (I(Na)) was also prolonged by these compounds. Pyrethroids delayed I(Na) inactivation, when measured under selective conditions as current sensitive to 30 microM tetrodotoxin, by increasing the proportion of slowly inactivating current at the expense of fast inactivating current. ...

Beyond Pesticides, September 22, 2008) A study published in the September issue of Environmental Health Perspectives finds that low-dose, short-term exposure to esfenvalerate, a synthetic pyrethroid pesticide, delays the onset of puberty in rats at doses two times lower than U.S. EPAs stated no observable effect level (NOEL) of 2.0 mg/kg/day. Synthetic pyrethroids are used for everything from lawn care and household insecticides, to mosquito control and agriculture. There are currently 348 pesticide products registered by the U.S. EPA. The researchers conclude:. Although the exact mechanism of action is unknown at this time, we observed the effects at dosage levels below the NOEL established through chronic dietary exposure studies in rats. The U.S. EPA (1998) http://www.epa.gov/fedrgstr/EPA-PEST/1998/April/Day-29/p11372.htm stated that ˜There is no evidence of additional sensitivity to young rats or rabbits following pre- or postnatal exposure to esfenvalerate.

A new, simple, precise, and rapid high-performance thin-layer chromatography (HPTLC) method was developed for the analysis of commercial emulsifiable concentrate (EC) formulations of cypermethrin, α-cypermethrin, and λ-cyhalothrin. A known amount of reference grade synthetic pyrethroid and its EC formulation was subjected to TLC, and the amount of pesticide present in the active ingredient spot was estimated by densitometry in a single beam, single wavelength reflectance mode. Calibration curves of the synthetic pyrethroid was linear in the range of 8-24 μg, and the correlation coefficient for the calibration equation ranged between 0.97 and 0.99. Recoveries from laboratory-prepared test samples of the EC formulation were in the range of 95-99%. Pesticide formulations were further analyzed by gas liquid chromatography using flame ionization detector, and results were comparable. The proposed HPTLC method has application for quality control and determination of the shelf life of EC formulations ...

Beyond Pesticides, November 14, 2019) The Environmental Protection Agency (EPA), under pressure from chemical companies, released a proposal on Tuesday to further weaken protections regarding 23 pyrethroids. Pyrethroids are a common class of neurotoxic insecticides that have been repeatedly linked by peer-reviewed studies to neurological issues such as learning disabilities in children. They are also extremely damaging to non-target invertebrates, according to EPAs own analysis. Despite this, EPA had already recently undermined protections for children from these chemicals, and the Trump Administration is now embracing industry proposals to further remove other safety barriers to human health and the environment.. The Pyrethroid Working Group, a weighty working group of pesticide companies, requested EPA reduce safeguards such as a permanent 66-foot vegetation buffer between fields and water bodies to a 10 - 25-foot buffer. Also, the working group (and now EPA) suggests that the wind-speed ...

Whether or not a pyrethrin or pyrethroid product is toxic depends on the animal species involved, as well as the concentration, synergists and carriers used in the product. The use of pyrethrins/pyrethroids is very safe in dogs; however, cats and fish are very sensitive to pyrethrins/pyrethroids.. Fish are so sensitive that they may die from even the smallest exposure, so be sure to cover aquarium tanks (with something non-porous like plastic wrap) or remove the tanks from an area youll be treating with a product containing a pyrethrin or pyrethroid (e.g., foggers, sprays, etc.). Likewise, if you apply a topical flea and tick spot-on onto your dog, do not allow him to jump into a body of water where fish may be living (for instance, a koi pond or a neighboring creek) for at least 24-48 hours following application ...
Lambda-Cyhalothrin is extensively used in agriculture, horticulture and public health management in Kenya. The pesticide is effective against many vegetable pests, rice and other related disease vectors. This study investigated adsorption of L-Cyhalothrin onto sediments of Athi River and degradation on Kwale and Athi River soils. Sample analysis was conducted using UV-Visible spectrophotometry and the results were analyzed by fitting data into isotherm models including Langmuir, Freundlich, Temkin, Dubinin-Radushvich and Scathard plot to understand the environmental impacts of this pesticide. The models presented different numerical values but the results demonstrated similar characteristics.

Cytochrome P450 enzymes (P450s) have been implicated in insecticide resistance. Anopheles minumus mosquito P450 isoforms CYP6AA3 and CYP6P7 are capable of metabolizing pyrethroid insecticides, however CYP6P8 lacks activity against this class of compounds. Homology models of the three An. minimus P450 enzymes were constructed using the multiple template alignment method. The predicted enzyme model structures were compared and used for molecular docking with insecticides and compared with results of in vitro enzymatic assays. The three model structures comprise common P450 folds but differences in geometry of their active-site cavities and substrate access channels are prominent. The CYP6AA3 model has a large active site allowing it to accommodate multiple conformations of pyrethroids. The predicted CYP6P7 active site is more constrained and less accessible to binding of pyrethroids. Moreover the predicted hydrophobic interface in the active-site cavities of CYP6AA3 and CYP6P7 may contribute to their

Synthetic pyrethroids are lipophilic insecticides whose biological activity seems to be directly related to their chemical structure. In this investigation differences in cutaneous sensation were detected by human participants between synthetic pyrethroids with a cyano group in the (S)-configuration of the 3-phenoxybenzyl alcohol of their molecular structure (fenvalerate) and those that do not (permethrin). A strong relation was noted between insecticidal potency and degree of induced cutaneous sensation for the alpha-cyano and non-cyano pyrethroids, with a prominent difference between the two. No sensation was observed by any of the same participants on topical exposure to the inert ingredients of these agents. A linear correlation between concentration and degree of induced dysaethesia was observed for both pyrethroids. Regressing the cutaneous sensation on the common logarithm of concentration resulted in a regression equation of Y = 84.0 + 31.0X1 for fenvalerate and Y = 27.5 + 15.8X1 for ...
Introduction. Malaria vector control in southern Africa relies mainly on indoor residual house spraying (IRS) with insecticides. Synthetic pyrethroids and DDT (dichloro-diphenyl-trichloroethane) are used in IRS applications, while permethrin-treated bed-nets are used for personal protection in some households. DDT was introduced for malaria control in 1946 in South Africa and remained in use until 1996 when the choice of insecticide was changed to the pyrethroid deltamethrin.1 Following a major upsurge of malaria cases in 1999/2000 and the detection of pyrethroid resistance in the major malaria vector Anopheles funestus,2 DDT was re-introduced in 2001 and a marked reduction in malaria morbidity and mortality was recorded.3,4 Deltamethrin is currently used in modern-style houses with painted walls while DDT is used in traditional houses.. Anopheles arabiensis is a major malaria vector in southern Africa, second only to Anopheles funestus. Historically, it has been considered to be susceptible to ...
Resistance to pyrethroid insecticides is a major concern for malaria vector control. Pyrethroids target the voltage-gated sodium channel (VGSC), an essential compo nent of the mosquito nervous system. Substitutions in the amino acid sequence can inducing a resistance phenotype. We use whole-genome sequence data from phase 2 of the Anopheles gambiae 1000 Genomes Project (Ag1000G) to provide a comprehensive account of genetic variation in the Vgsc gene across 13 African countries. In addition to known resistance alleles, we describe 20 other non-synonymous nucleotide substitutions at appreciable population frequency, and map these variants onto a protein model to investigate the likelihood of a pyrethroid resistance phenotypes. Thirteen of these novel alleles were found to occur almost exclusively on haplotypes carrying the known L995F kdr (knock-down resistance allele) and may enhance or compensate for the L995F resistance genotype. A novel mutation I1527T, adjacent to a predicted pyrethroid ...
Pyrethroids are a class of widely-used insecticides that can be transported from terrestrial applications to aquatic systems via runoff and tend to sorb to organic carbon in sediments. Pyrethroid occurrence is detrimental to stream ecosystems due to toxicity to sediment-dwelling invertebrates which are particularly at risk of pyrethroid exposure in urban streams. In this work, 49 streams located in watersheds in the northeastern United States were surveyed for nine current-use pyrethroids using two extraction methods. Total sediment concentrations were determined by exhaustive chemical extraction, while bioaccessible concentrations were determined by single-point Tenax extraction. Total and bioaccessible pyrethroid concentrations were detected in 76% and 67% of the sites, and the average sum of pyrethroids was 232 ng/g organic carbon (OC) for total and 43.8 ng/g OC for bioaccessible pyrethroids. Bifenthrin was the most commonly detected pyrethroid in streambed sediments. Sediment toxicity was assessed
Pyrethroid resistance in Anopheles funestus populations has led to an increase in malaria transmission in southern Africa. Resistance has been attributed to elevated activities of cytochrome P450s but the molecular basis underlying this metabolic resistance is unknown. Microsatellite and SNP markers were used to construct a linkage map and to detect a quantitative trait locus (QTL) associated with pyrethroid resistance in the FUMOZ-R strain of An. funestus from Mozambique. By genotyping 349 F2 individuals from 11 independent families, a single major QTL, rp1, at the telomeric end of chromosome 2R was identified. The rp1 QTL appears to present a major effect since it accounts for more than 60% of the variance in susceptibility to permethrin. This QTL has a strong additive genetic effect with respect to susceptibility. Candidate genes associated with pyrethroid resistance in other species were physically mapped to An. funestus polytene chromosomes. This showed that rp1 is genetically linked to a cluster
The no action potential, temperature-sensitive (napts) mutation in Drosophila melanogaster confers resistance to the pyrethroids fenvalerate and permethrin. Additionally we have found that females are more resistant to pyrethroids than males. Piperonyl butoxide can suppress this resistance in a long pyrethroid exposure (,45 min) but has less of an effect during shorter exposures. Since the pyrethroid resistance of napts can be suppressed by piperonyl butoxide, the nap mutant appears to define a phenotypically different locus than the kdr mutant in house flies. Previous work has demonstrated that the napts mutation decreases the number of saxitoxin-binding sodium channels. We propose that the presence of fewer sodium channels in mutant flies delays knockdown by pyrethroids, which act as channel agonists. This delay allows other mechanisms to come into play which, in turn, allow survivial. This model is supported by the finding that the nap resistance can be mimicked by feeding wild-type flies a ...

In an invited commentary in JAMA, Columbia University Mailman School of Public Health professors Drs. Steven Stellman and Jeanne M. Stellman offer their perspective on results from a recent study on Pyrethroid, among the most widely used insecticides for public health control of vector-borne illnesses, including West Nile virus. While exposure to the insecticides, which are also widely used in consumer products, generally poses low health risks to humans, a recent study reported a 50 percent increase in total mortality and three-fold increase in heart disease deaths in persons with high urinary levels of 3-PBA, a metabolic product of pyrethroids indicative of human exposure.. Pyrethroid pesticides are the second most-used insecticides in the world, totaling billions of dollars in U.S. sales..

The Yellow Book has been published annually since 2005 with trial results and evaluations. Erin Hodgson, associate professor and extension specialist in entomology at Iowa State University, has been writing the publication since 2009.. For the first time during the 2016 growing season, insecticide failure was confirmed in Iowa. Pyrethroids are a common insecticide group, but did not have any knockdown in this commercial field.. This may force farmers to switch to a different kind of insecticide, most likely organophosphates, Hodgson said. If pyrethroid resistance becomes more common, it limits the tools that can be used and can increase input costs. Checking to make sure insecticides are working now becomes a priority.. If you are going to apply a foliar insecticide, make sure to go back and scout to insure there are no survivors after application, Hodgson said.. Hodgson will present much more information about the insecticide failure during the 2017 Iowa State University Extension and Outreach ...

MICHIGAN STATE (US) - The discovery of a second molecular receptor in mosquitoes could make insecticides used to fend off malaria and dengue fever more effective.. For many years, pyrethroid insecticides have been deployed in developing countries to fend off diseases. Theyre so effective that they are the only insecticides the World Health Organization uses with their mosquito nets they distribute around the globe.. Pyrethroids are effective because they eliminate mosquitoes while having few if any side effects on humans, says Yuzhe Du, a Michigan State electrophysiologist and one of the lead authors of the study published in the Proceedings of the National Academy of Sciences.. Our discovery of a second receptor in the mosquitoes sodium channel gives us a better understanding of how the insecticide works at a molecular level as well as could lead to ways to stem mosquitoes resistance to pyrethroids..

Yes. For example, the spray kills monarch caterpillars, even weeks later later due to the presence of insecticide dried onto milkweed leaves (Oberhuaser et al. 2006). And the spray can kill honey bees, even if honey bees are inside their hives when the pyrethroids are spayed (workers bring small amounts back to the hive the following day if they land on treated plants or if they find small puddles of water to drink). Sublethal amounts of pyrethroids can change honey bee behavior and make workers smaller. I would imagine the pyrethroids would end up in the honey, too. And pyrethroids kill fireflies, which are most active in a yard in the late evening when mosquito-spraying franchises like to fog.. My favorite group of unnoticed insects that are killed by evening pyrethroid applications are solitary bees, of which there are approximately 4,000 species in the United States. These are bees that collect pollen and nectar during the day but spend their evenings and nights in holes (e.g., mason bees) ...
Insecticides are substances used to kill insects.[1] They include ovicides and larvicides used against insect eggs and larvae, respectively. Insecticides are used in agriculture, medicine, industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-centurys agricultural productivity.[2] Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest. It provides another way of classifying insecticides. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds and mammals. Insecticides may be repellent or ...

Based on LC50 levels of pesticides, different concentration treatment groups designated and rotifer population responses in the five different concentrations of deltamethrin (0.00, 0.05, 0.10, 0.21 and 0.53 mgl-1) and imidacloprid (0.00, 6.22, 12.45, 24.91 and 62.27 mg l-1) with three replicates per each concentration during ten days were studied. The LC50 24h of deltamethrin and imidacloprid for freshwater rotifer determined as 1.06 mg l-1 and 124.54 mg l-1, respectively. The density of rotifers in all treatment groups of pesticides compare to the control group at tenth day decreased
is the main focus of dengue control campaigns. Because of widespread resistance against conventional chemical insecticides, chitin synthesis inhibitors (CSIs) are considered control alternatives. We evaluated the resistance status of four Brazilian Ae. aegypti populations to both the organophosphate temephos and the pyrethroid deltamethrin, which are used in Brazil to control larvae and adults, respectively. All vector populations exhibited high levels of temephos resistance and varying rates of alterations in their susceptibility to pyrethroids. The effect of the CSI novaluron on these populations was also investigated. Novaluron was effective against all populations under laboratory conditions. Field-simulated assays with partial water replacement were conducted to evaluate novaluron persistence. Bioassays were continued until an adult emergence inhibition of at least 70% was attained. We found a residual effect of eight weeks under indoor conditions and novaluron persisted for five-six weeks ...
INTRODUCTION: Based on the assumption that professional groups with frequent chemical exposure are at an increased risk for developing Multiple Chemical Sensitivity (MCS), a sample of 45 professional pest controllers was investigated. METHODS: The examination of the pest controllers consisted of a physical and laboratory examination with urine screening for pyrethroid metabolites, a psychiatric interview, a neuropsychological test battery, and a chemical sensitivity questionnaire. RESULTS: Persistent or serious work related health problems and chemical sensitivity were not reported. In urine, cis-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid (Br(2)CA) was detected in 11%, 4-fluoro-3-phenoxybenzoic acid (F-PBA) in 7%. 3-phenoxybenzoic acid (3-PBA) exceeded the reference range in 9%, cis- and trans-3-(2,2-dichlorovinyl)-2,2-dimethyl-cyclopropane-1-carboxylic acid (Cl(2)CA) in 20%. Increased liver enzymes and blood count deviations were rather common. 38% had psychiatric ...
