An overview of the evolution of overproduced esterases in the mosquito Culex pipiens. (1/3500)

Insecticide resistance genes have developed in a wide variety of insects in response to heavy chemical application. Few of these examples of adaptation in response to rapid environmental change have been studied both at the population level and at the gene level. One of these is the evolution of the overproduced esterases that are involved in resistance to organophosphate insecticides in the mosquito Culex pipiens. At the gene level, two genetic mechanisms are involved in esterase overproduction, namely gene amplification and gene regulation. At the population level, the co-occurrence of the same amplified allele in distinct geographic areas is best explained by the importance of passive transportation at the worldwide scale. The long-term monitoring of a population of mosquitoes in southern France has enabled a detailed study to be made of the evolution of resistance genes on a local scale, and has shown that a resistance gene with a lower cost has replaced a former resistance allele with a higher cost.  (+info)

The bystander effect in the HSVtk/ganciclovir system and its relationship to gap junctional communication. (2/3500)

The bystander effect (BSE) is an interesting and important property of the herpes thymidine kinase/ganciclovir (hTK/GCV) system of gene therapy for cancer. With the BSE, not only are the hTK expressing cells killed upon ganciclovir (GCV) exposure but also neighboring wild-type tumor cells. On testing a large number of tumor cell lines in vitro, a wide range of sensitivity to bystander killing was found. Since transfer of toxic GCV metabolites from hTK-modified to wild-type tumor cells via gap junctions (GJ) seemed to be a likely mechanism of the BSE, we tested GJ function in these various tumors with a dye transfer technique and pharmacological agents known to affect GJ communication. We confirmed that mixtures of tumor cell resistant to the BSE did not show dye transfer from cell to cell while bystander-sensitive tumor cells did. Dieldrin, a drug known to decrease GJ communication, diminished dye transfer and also inhibited the BSE. Forskolin, an upregulator of cAMP did increase GJ, but directly inhibited hTK and therefore its effect on BSE could not be determined. We conclude that these observations further support port the concept that functional GJ play an important role in the BSE and further suggest that pharmacological manipulation of GJ may influence the outcome of cancer therapy with hTK/GCV.  (+info)

A toxicokinetic model to assess the risk of azinphosmethyl exposure in humans through measures of urinary elimination of alkylphosphates. (3/3500)

Azinphosmethyl (APM) is one of the most common insecticides used in fruit farming. The object of this paper is to develop a quick and practical test for assessing the risk for humans coming into contact with APM. It has been shown that the principal component of occupational and/or accidental exposure is through the skin (C. A. Franklin et al., 1981, J. Toxicol. Environ. Health 7, 715-731), but our approach is applicable to exposures via any route or a combination of routes. The method proposed in the present paper can accommodate a single-event exposure or repeated exposures over long periods. Urinary alkylphosphate (AP) metabolites are reliable bioindicators of the presence of APM in the body; they are easily accessible and can be used to estimate APM body burden. We developed a simple toxicokinetic model to link the time varying APM body burden to absorbed doses and to rates of elimination in the form of AP urinary metabolites. Using this model and data available in the literature, we are able to propose a "no observed adverse effect level" (NOAEL) for APM body levels and for corresponding absorbed doses. We have established that after a single exposure, the safe limit corresponding to the NOAEL is reached at a cumulative 0.215 mumoles AP/kg bw eliminated in urine in the first 24 hours following the beginning of exposure. For repeated daily exposures at steady state, the corresponding urinary AP metabolite level is equal to a cumulative 0.266 mumoles AP/kg bw eliminated per 24 hours.  (+info)

Involvement of two plasmids in the degradation of carbaryl by Arthrobacter sp. strain RC100. (4/3500)

A bacterium capable of utilizing carbaryl (1-naphthyl N-methylcarbamate) as the sole carbon source was isolated from carbaryl-treated soil. This bacterium was characterized taxonomically as Arthrobacter and was designated strain RC100. RC100 hydrolyzes the N-methylcarbamate linkage to 1-naphthol, which was further metabolized via salicylate and gentisate. Strain RC100 harbored three plasmids (designated pRC1, pRC2, and pRC3). Mutants unable to degrade carbaryl arose at a high frequency after treating the culture with mitomycin C. All carbaryl-hydrolysis-deficient mutants (Cah-) lacked pRC1, and all 1-naphthol-utilization-deficient mutants (Nat-) lacked pRC2. The plasmid-free strain RC107 grew on gentisate as a carbon source. These two plasmids could be transferred to Cah- mutants or Nat- mutants by conjugation, resulting in the restoration of the Cah and Nah phenotypes.  (+info)

Altered properties of neuronal sodium channels associated with genetic resistance to pyrethroids. (5/3500)

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. (6/3500)

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)

Relationships between environmental organochlorine contaminant residues, plasma corticosterone concentrations, and intermediary metabolic enzyme activities in Great Lakes herring gull embryos. (7/3500)

Experiments were conducted to survey and detect differences in plasma corticosterone concentrations and intermediary metabolic enzyme activities in herring gull (Larus argentatus) embryos environmentally exposed to organochlorine contaminants in ovo. Unincubated fertile herring gull eggs were collected from an Atlantic coast control site and various Great Lakes sites in 1997 and artificially incubated in the laboratory. Liver and/or kidney tissues from approximately half of the late-stage embryos were analyzed for the activities of various intermediary metabolic enzymes known to be regulated, at least in part, by corticosteroids. Basal plasma corticosterone concentrations were determined for the remaining embryos. Yolk sacs were collected from each embryo and a subset was analyzed for organochlorine contaminants. Regression analysis of individual yolk sac organochlorine residue concentrations, or 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalents (TEQs), with individual basal plasma corticosterone concentrations indicated statistically significant inverse relationships for polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans (PCDDs/PCDFs), total polychlorinated biphenyls (PCBs), non-ortho PCBs, and TEQs. Similarly, inverse relationships were observed for the activities of two intermediary metabolic enzymes (phosphoenolpyruvate carboxykinase and malic enzyme) when regressed against PCDDs/PCDFs. Overall, these data suggest that current levels of organochlorine contamination may be affecting the hypothalamo-pituitary-adrenal axis and associated intermediary metabolic pathways in environmentally exposed herring gull embryos in the Great Lakes.  (+info)

The effect of body mass index (BMI) and waist:hip ratio (WHR) on plasma levels of organochlorines [i.e., 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (DDE)] was investigated in a sample of black and white women drawn from a population-based study in North Carolina. Organochlorine levels were determined in plasma samples from 99 women selected on the basis of race (black versus white) and quartile of the WHR (1st versus 4th). Of a panel of 20 organochlorine compounds tested, only DDE was detectable in most study subjects. Measurements of height, weight, and waist and hip circumferences were taken during an in-person interview. Information was elicited regarding dietary, residential, and breast-feeding histories. Results of multiple regression analyses indicate that black women had significantly higher plasma levels of DDE than white women. These levels were independent of BMI and WHR. BMI but not WHR was also found to be an independent predictor of DDE plasma level. These results suggest that black/white differences should be considered in studies that explore the relationship between environmental contaminants and various disease outcomes, such as breast cancer risk. In addition, BMI may affect circulating levels of contaminants and should also be considered a potentially important modifying factor for exposure to lipophilic substances.  (+info)

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 ...
For insecticide resistance management, Transform Insecticide is a Group 4C insecticide. Some naturally occurring insect biotypes resistant to Transform Insecticide and other Group 4C insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Transform Insecticide and other Group 4C insecticides are used repeatedly. The effectiveness of Transform Insecticide on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Dow AgroSciences Australia Limited accepts no liability for any losses that may result from the failure of Transform Insecticide to control resistant insects. Transform Insecticide may be subject to specific resistance management strategies. For further information contact your local supplier, Dow AgroSciences representative or local agricultural department agronomist.. MIXING ...
TY - JOUR. T1 - Insecticide control of vector-borne diseases. T2 - When is insecticide resistance a problem?. AU - Rivero, Ana. AU - Vézilier, Julien. AU - Weill, Mylene. AU - Read, Andrew F.. AU - Gandon, Sylvain. PY - 2010/8. Y1 - 2010/8. N2 - Many of the most dangerous human diseases are transmitted by insect vectors. After decades of repeated insecticide use, all of these vector species have demonstrated the capacity to evolve resistance to insecticides. Insecticide resistance is generally considered to undermine control of vector-transmitted diseases because it increases the number of vectors that survive the insecticide treatment. Disease control failure, however, need not follow from vector control failure. Here, we review evidence that insecticide resistance may have an impact on the quality of vectors and, specifically, on three key determinants of parasite transmission: vector longevity, competence, and behaviour. We argue that, in some instances, insecticide resistance is likely to ...

The rapid selection of pyrethroid resistance throughout sub-Saharan Africa is a serious threat to malaria vector control. Chlorfenapyr is a pyrrole insecticide which shows no cross resistance to insecticide classes normally used for vector control and is effective on mosquito nets under experimental hut conditions. Unlike neurotoxic insecticides, chlorfenapyr owes its toxicity to disruption of metabolic pathways in mitochondria that enable cellular respiration. A series of experiments explored whether standard World Health Organization (WHO) guidelines for evaluation of long-lasting insecticidal nets, developed through testing of pyrethroid insecticides, are suitable for evaluation of non-neurotoxic insecticides. The efficacy of WHO recommended cone, cylinder and tunnel tests was compared for pyrethroids and chlorfenapyr. To establish bioassay exposure times predictive of insecticide-treated net (ITN) efficacy in experimental hut trials, standard three-minute bioassays of pyrethroid and chlorfenapyr
The idea of evolution-proof insecticides is currently a hot topic in mosquito control (Read et al. 2009) because of the potential to slow down or even halt the evolution of insecticide resistance in mosquitoes. While insecticides are an effective and cheap method of controlling malaria, it is well known that mosquitoes can develop resistance and that this can happen on a surprisingly fast time scale. It was known by the end of the 1960s that the mosquito species that transmit malaria were developing resistance to dichlorodiphenyltrichloroethane (DDT), the single insecticide that had been relied on until then (see Hemingway et al. (2002) and Kelly-Hope et al. (2008) for recent discussions on the management of insecticide resistance). Current insecticides kill extremely rapidly after contact, but their high lethality leads to intense selection for resistance because they kill young female adults. The very limited insecticide arsenal available (there are still just four classes, only one of which ...

This project completed in December 2015.. New Insecticides for Malaria Control: Discovery Research for the Identification of New Chemical Entities for Malaria Control was a continuation of research initiated under the FNIHs Vector-based Control of Transmission: Discovery Research (VCTR) program. VCTR was itself an extension of the Bill & Melinda Gates Foundations Grand Challenges in Global Health initiative. As a subset of activities under the VCTR program, the New Insecticides for Malaria Control program addressed the urgent need for new chemicals to kill mosquitoes that transmit malaria. Current efforts rely heavily on the use of available insecticides for use on bednets, for indoor residual spraying and for application of chemical larvicides. Available insecticides are limited in number and the only one class of compound (pyrethroids) can safely be used on bednets. The situation is grim as mosquitoes have evolved resistance to the compounds currently in use. This program sought to address ...

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

As folks consider spraying fields for soybean aphid, we want to remind everyone that soybean aphid has developed resistance to pyrethroid (Group 3A) insecticides. Currently, any populations of soybean aphid in Minnesota should be considered potentially resistant to pyrethroids. Insecticide rotations are an important part of insecticide resistance management and may help reduce the chances of further development of insecticide resistance in soybean aphid. If a field needs to be sprayed more than once, it is important to rotate to a different insecticide group for the follow-up spray. On a new webpage, we provide some guidance for insecticide rotations for pyrethroid-resistant soybean aphid ...
Both Aedes aegytpi and Ae. albopictus are major vectors of 5 important arboviruses (namely chikungunya virus, dengue virus, Rift Valley fever virus, yellow fever virus, and Zika virus), making these mosquitoes an important factor in the worldwide burden of infectious disease. Vector control using insecticides coupled with larval source reduction is critical to control the transmission of these viruses to humans but is threatened by the emergence of insecticide resistance. Here, we review the available evidence for the geographical distribution of insecticide resistance in these 2 major vectors worldwide and map the data collated for the 4 main classes of neurotoxic insecticide (carbamates, organochlorines, organophosphates, and pyrethroids). Emerging resistance to all 4 of these insecticide classes has been detected in the Americas, Africa, and Asia. Target-site mutations and increased insecticide detoxification have both been linked to resistance in Ae. aegypti and Ae. albopictus but more work is
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 ...

This dramatic increase in oral-based toxic load is connected to a shift toward widespread use of neonicotinoid insecticides, which are unusually toxic to bees when they are ingested, said Douglas.. The most widely used family of insecticides in the world, neonicotinoids are commonly used as seed coatings in crops, such as corn and soybean. Some of the insecticide is taken up by the growing plants and distributed throughout their tissues, while the rest is lost to the environment.. Several studies have shown that these seed treatments have negligible benefits for most crops in most regions, said Grozinger. Unfortunately, growers often dont have the option to purchase seeds without these treatments; they dont have choices in how to manage their crops.. The researchers suggest that the common method of evaluating insecticide use trends in terms of pounds of insecticides applied does not give an accurate picture of environmental impact.. The indicator we use - bee toxic load - can be ...
Of the citrus plantings, 74 per cent received no insecticide sprays and a further 18 per cent received only an oil spray (table 3). An average of 8 per cent of plantings received an organophosphate Insecticide (one spray only). Methidathion was the most commonly used insecticide.. Low insecticide use on citrus may be attributed to the effectiveness of the red scale parasite. Aphytis melinus De Bach, in the biological, or integrated (parasites and oil sprays) control of red scale, Aonidiella eurentii (Mask.). Citrus orchards are supplied with parasites regularly on a contract basis by two insectaries . The Biological Services insectary at Loxton services 750 ha of citrus throughout the Riverland (R.

To serve the citizens of Maryland, the Maryland Department of Agriculture annually reviews the insecticides available for mosquito control. The recommended insecticides are selected from the list of products registered by the U. S. Environmental Protection Agency (EPA) for mosquito control use. The Department of Agriculture bases its selection on experience and research and includes factors of risk, economy and effectiveness under Maryland conditions. The Department promotes integrated pest management of mosquitoes and advocates alternatives to insecticide application when possible. These alternatives include water management, biological control and public education.. When alternative controls are not possible to utilize or are not effective in reducing the mosquito population below a level that may cause unacceptable annoyance or constitute a public health threat, the use of insecticide is an approved option as part of an integrated pest management program..

sources]. Amphibian populations are declining worldwide, and pesticides and insecticides are one hypothesized cause, says Jessica Hua, lead author of the paper and a PhD candidate studying biological sciences in Relyeas laboratory. So this discovery has promising implications for the persistence of amphibian populations.. For the study, published in Evolutionary Applications, researchers examined three potential factors that might allow larval wood frogs to have a high tolerance to the insecticide: the concentration of the initial insecticide exposure, the timing of the exposure, and the populations history of exposure.. They chose to work with carbaryl, a popular household insecticide that also is used for malaria prevention.. The researchers conducted experiments with both embryos and hatchlings that were collected as newly laid eggs from four Pennsylvania ponds-two near agricultural fields and two farther away.. Both embryos and hatchlings from all four environs were first exposed to a ...

An experimental strategy for the study of enhanced degradation is described based on its occurrence in Midwestern corn soils. The shift from recalcitrant chlorinated hydrocarbons to biodegradable organophosphorus and carbamate insecticides has resulted in the failure of some compounds, notably carbofuran and isofenphos, to provide adequate pest control following repeated use. Enhanced degradation of an insecticide involves its rapid degradation by a population of soil microorganisms that has adapted to beneficially catabolize it following exposure to it or a similar insecticide. For enhanced degradation to be thoroughly investigated studies must be carried out to demonstrate an increased rate of degradation in soils with prior insecticide exposure, to identify the rates and products of degradation in similar soils under controlled conditions, and to elucidate the microbiological mechanisms.
Zika virus (ZIKV) is primarily transmitted to humans by Aedes aegypti and Ae. albopictus. Vector-virus interactions influencing vector competence vary and depend on biological and environmental factors. A mosquitos chronological age may impact its immune response against virus infection. Insecticides, source reduction, and/or public education are currently the best defense against mosquitoes that transmit ZIKV. This study assessed the effects of a mosquitos chronological age at time of infection on its response to ZIKV infection. We exposed young (6-7 d post-emergence) and old (11-12 d post-emergence) Ae. albopictus to a sublethal dose of bifenthrin prior to oral exposure to blood meals containing ZIKV (7-day incubation period). Old mosquitoes experienced a significantly (p < 0.01) higher rate of mortality than young mosquitoes. Significantly higher ZIKV body titers (p < 0.01) were observed in the old control group compared to the young control group. Significantly higher (p < 0.01) ZIKV

Programmatic monitoring of insecticide resistance in disease vectors is mostly done on a large scale, often focusing on differences between districts, regions or countries. However, local heterogeneities in residual malaria transmission imply the need for finer-scale data. This study reports small-scale variations of insecticide susceptibility in Anopheles arabiensis between three neighbouring villages across two seasons in Tanzania, where insecticidal bed nets are extensively used, but malaria transmission persists. WHO insecticide susceptibility assays were conducted on female and male An. arabiensis from three proximal villages, Minepa, Lupiro, and Mavimba, during dry (June-December 2015) and wet (January-May 2016) seasons. Adults emerging from wild-collected larvae were exposed to 0.05% lambda-cyhalothrin, 0.05% deltamethrin, 0.75% permethrin, 4% DDT, 4% dieldrin, 0.1% bendiocarb, 0.1% propoxur, 0.25% pirimiphos-methyl and 5% malathion.

A model is developed to describe the decay of seven insecticides on stored paddy rice, maize, sunflowers and peas, and is shown to be more precise than each of six literature models on pesticide decay. It relates residues (R), as a ratio of applied concentration (R0), to time after insecticide application (t), modifying the usual first-order kinetics equation lnR=lnR0−kt by assuming that the rate constant k has a mixture of values according to a gamma distribution with mean K. The resulting equation is lnR=lnR0−Kc ln(1+t/c), where c is a constant determined empirically. For large c, this model reduces to the first-order model with K=k. The parameter K is further modelled as linear in temperature for maize and rice. The rate of loss of protectants was found not to be seriously affected by co-application with other insecticides, and this is a useful finding for future studies on rates of loss of grain protectants. The apparent rate of loss was also not seriously affected by the method of ...
DESCRIPTION (provided by applicant): Insecticides are among the cheapest, most effective and best proven methods of controlling malaria but as historical and contemporary experience shows, mosquitoes can rapidly evolve resistance. We wish to test the hypothesis that existing public health insecticides could be made to deliver excellent malaria control without driving the evolution of insecticide resistant mosquitoes simply by using their active ingredients at lower concentrations. This hypothesis, which is completely opposite to conventional wisdom, derives from the observation that current insecticide paradigms indiscriminately target all adult mosquitoes and thus impose immense selection for resistance, whereas malaria is actually transmitted by only a small faction of mosquitoes (old, infected individuals). If insecticides targeted only those dangerous mosquitoes, and avoided all the others, particularly the young reproductively-active mosquitoes most responsible for evolutionary change, then ...
