Cascading effects of insecticides and road salt on wetland communities, outdoor mesocosm experiment, New York, USA, 2015
Novel stressors introduced by human activities increasingly threaten freshwater ecosystems. The annual application of more than 2.3 billion kg of pesticide active ingredient and 22 billion kg of road salt has led to the contamination of temperate waterways. While pesticides and road salt are known to cause direct and indirect effects in aquatic communities, their possible interactive effects remain widely unknown. Using outdoor mesocosms, we created wetland communities consisting of zooplankton, phytoplankton, periphyton, and leopard frog (Rana pipiens) tadpoles. We evaluated the toxic effects of six broad- spectrum insecticides from three families (neonicotinoids: thiamethoxam, imidacloprid; organophosphates: chlorpyrifos, malathion; pyrethroids: cypermethrin, permethrin), as well as the potentially interactive effects of four of these insecticides with three concentrations of road salt (NaCl; 44, 160, 1600 Cl- mg/L). Organophosphate exposure decreased zooplankton abundance, elevated phytoplankton biomass, and reduced tadpole mass whereas exposure to neonicotinoids and pyrethroids decreased zooplankton abundance but had no significant effect on phytoplankton abundance or tadpole mass. While organophosphates decreased zooplankton abundance at all salt concentrations, effects on phytoplankton abundance and tadpole mass were dependent upon salt concentration. In contrast, while pyrethroids had no effects in the absence of salt, they decreased zooplankton and phytoplankton density under increased salt concentrations. Our results highlight the importance of multiple-stressor research under natural conditions. As human activities continue to imperil freshwater systems, it is vital to move beyond single-stressor experiments that exclude potentially interactive effects of chemical contaminants.
Effect of insecticide treatment on leaf damage to Salix spp within experimental plots on the Tanana River 2012-2017
This dataset contains information on the amount and type of damage to Salix leaves on insecticide-sprayed and control subplots. The intend is to (a) measure interannual variation in leaf damage on the plots, and (b) validate the spraying treatment.
Effect of insecticide treatment on Salix interior stem tannin activity and elemental composition.
This dataset contains information on stem chemistry of Salix interior within experimental plots on the Tanana River. There are 6 permanent plots, each of which contains two fenced subplots and two unfenced subplots. Subplots are sprayed with either insecticide (insect-treated subplots) or water (controls) annually. This particular dataset contains chemistry data for leaves collected from insecticide-treated and control subplots only within fenced subplots. The intent was to measure the effect of insect herbivory on chemistry in the absence of browsing.
Data from: Evolutionary trade-offs of insecticide resistance – the fitness costs associated with target-site mutations in the nAChR of Drosophila melanogaster
<p>The evolution of resistance to drugs and pesticides poses a major threat to human health and food security. Neonicotinoids are highly effective insecticides used to control agricultural pests. They target the insect nicotinic acetylcholine receptor and mutations of the receptor that confer resistance have been slow to develop, with only one field-evolved mutation being reported to date. This is an arginine to threonine substitution at position 81 of the nAChR_β1 subunit in neonicotinoid resistant aphids. To validate the role of R81T in neonicotinoid resistance and to test whether it may confer any significant fitness costs to insects, CRISPR/Cas9 was used to introduce an analogous mutation in the genome of <i>Drosophila melanogaster</i>. Flies carrying R81T showed an increased tolerance (resistance) to neonicotinoid insecticides, accompanied by a significant reduction in fitness. In comparison, flies carrying a deletion of the whole nAChR_α<em>6</em> subunit, the target-site of spinosyns, showed an increased tolerance to this class of insecticides but presented almost no fitness deficits.</p>

Data from: Barrier bednets target malaria vectors and expand the range of usable insecticides
<p>Transmission of <i>Plasmodium falciparum </i>malaria parasites occurs when nocturnal <i>Anopheles </i>mosquito vectors feed on human blood. In Africa, where malaria burden is greatest, bednets treated with pyrethroid insecticide were highly effective in preventing mosquito bites and reducing transmission, and essential to achieving unprecedented reductions in malaria until 2015. Since then, progress has stalled and with insecticidal bednets losing efficacy against pyrethroid-resistant <i>Anopheles</i> vectors, methods that restore performance are urgently needed to eliminate any risk of malaria returning to the levels seen prior to their widespread use throughout sub-Saharan Africa. Here we show that the primary malaria vector <i>Anopheles gambiae</i> is targeted and killed by small insecticidal net barriers positioned above a standard bednet, in a spatial region of high mosquito activity but zero contact with sleepers, opening the way for deploying many more insecticides on bednets than currently possible. Tested against wild pyrethroid-resistant <i>Anopheles gambiae </i>in Burkina Faso, pyrethroid bednets with organophosphate barriers achieved significantly higher killing rates than bednets alone. Treated barriers on untreated bednets were equally effective, without significant loss of personal protection. Mathematical modelling of transmission dynamics predicted reductions in clinical malaria incidence with barrier bednets that exceeded those of 'next-generation' nets recommended by WHO against resistant vectors. Mathematical models of mosquito-barrier interactions identified alternative barrier designs to increase performance. Barrier bednets that overcome insecticide resistance are feasible using existing insecticides and production technology, and early implementation of affordable vector control tools is a realistic prospect.</p>

Relative impacts of gypsy moth outbreaks and insecticide treatments on forest resources and ecosystem: An experimental approach
<p><span class="KONAHeading1CharChar"><span>Gypsy moth outbreaks cause severe defoliation in Holarctic forests, both in North America where it is invasive, and in its native range in Eurasia. Severe defoliation can hamper timber production and impact ecological communities and processes. Aerial insecticide applications are regularly performed in outbreak areas to mitigate economic losses. These operations can be financially costly and harmful to non-target species and may disrupt species interaction networks. However, replicated studies of the relative impacts of gypsy moth outbreaks and insecticide application on forest growth and animal communities are rare and have yet to be carried out in the species' indigenous range. </span></span></p> <p><span class="KONAHeading1CharChar"><span>Here, we review the pathways in which gypsy moth outbreaks and the chemical control of these outbreaks affect forest ecosystems. We then present an experimental design established in South Central Germany in early 2019, aiming to study the ecological and economic consequences of gypsy moth eruptions and insecticide application in oak forests. The study's full factorial design comprises forest stands with high and low defoliation risk, either treated with tebufenozide or left unsprayed, within 12 experimental blocks. Measurements of forest growth and structure, tree mortality, gypsy moth density, and composition of lepidopteran, bird, bat, ground beetle, and canopy arthropod communities will be conducted for several years. </span></span></p> <p><span class="KONAHeading1CharChar"><span>One-year intensive monitoring of gypsy moth populations and damage across the selected sites showed substantial differences in population density between plots with high and low defoliation risk and high efficacy of tebufenozide in suppressing gypsy moth populations in treated plots. In the first year of the experiment, gypsy moth density and defoliation in predicted outbreak plots differed strongly, confirming the importance of using many replicates and blocking to control spatial heterogeneity. The experiment will be running continuously during the coming years to produce short- and medium-term economic and ecological data to improve our understanding and management of gypsy moth outbreaks.</span></span></p>
The weakest link: Haploid honey bees are more susceptible to neonicotinoid insecticides
<p><span>Neonicotinoid insecticides are currently of major concern for the health of wild and managed insects that provide key ecosystem services like pollination. Even though sublethal effects of neonicotinoids are well known, there is surprisingly little information on how they possibly impact developmental stability, and to what extent genetics are involved. This holds especially true for haploid individuals because they are hemizygous at detoxification loci and may be more susceptible. Here we take advantage of haplodiploidy in Western honey bees, <i>Apis mellifera</i>, to show for the first time that neonicotinoids affect developmental stability in diploid females (workers), and that haploid males (drones) are even more susceptible. Phenotypic fore wing venation abnormalities and fluctuating wing asymmetry, as measures of developmental instability, were significantly increased under field-realistic neonicotinoid-exposure of colonies. The higher susceptibility of haploid drones suggests that heterozygosity can play a key role in the ability to buffer the sublethal effects of neonicotinoids. Aiming to improve conservation efforts, our findings highlight the urgent need to better understand the role that genetics plays at enabling non-target organisms to cope with insecticide exposure.</span></p>
Data from: Efficacy of Aedes aegypti control by indoor Ultra Low Volume (ULV) insecticide spraying in Iquitos, Peru
Background: Aedes aegypti is a primary vector of dengue, chikungunya, Zika, and urban yellow fever viruses. Indoor, ultra low volume (ULV) space spraying with pyrethroid insecticides is the main approach used for Ae. aegypti emergency control in many countries. Given the widespread use of this method, the lack of large-scale experiments or detailed evaluations of municipal spray programs is problematic. Methodology/Principal Findings: Two experimental evaluations of non-residual, indoor ULV pyrethroid spraying were conducted in Iquitos, Peru. In each, a central sprayed sector was surrounded by an unsprayed buffer sector. In 2013, spray and buffer sectors included 398 and 765 houses, respectively. Spraying reduced the mean number of adults captured per house by ~83 percent relative to the pre-spray baseline survey. In the 2014 experiment, sprayed and buffer sectors included 1,117 and 1,049 houses, respectively. Here, the sprayed sector's number of adults per house was reduced ~64 percent relative to baseline. Parity surveys in the sprayed sector during the 2014 spray period indicated an increase in the proportion of very young females. We also evaluated impacts of a 2014 citywide spray program by the local Ministry of Health, which reduced adult populations by ~60 percent. In all cases, adult densities returned to near-baseline levels within one month. Conclusions/Significance: Our results demonstrate that densities of adult Ae. aegypti can be reduced by experimental and municipal spraying programs. The finding that adult densities return to approximately pre-spray densities in less than a month is similar to results from previous, smaller scale experiments. Our results demonstrate that ULV spraying is best viewed as having a short-term entomological effect. The epidemiological impact of ULV spraying will need evaluation in future trials that measure capacity of insecticide spraying to reduce human infection or disease.
Insecticidal activity of Lantana camara extract oil on controlling maize grain weevils
<p>Currently farmers are faced by serious post-harvest problems from weevils especially in storage of grains. When grains exposed to insects they become less marketable and loss quality of grain. In this study the insecticidal property of methanol, ethanol and ethyl acetate extracted oil from Lantana Camara leaf for controlling of maize weevils, Sitophilus Zeamais were studied. Gas Chromatography-Mass spectrometry (GC-MS) and Fourier transform infrared spectroscopy (FT-IR) was used to identify the chemical composition and Functional group of solvent extracted oil respectively. Adult weevil's repellency and mortality were studied by the effect of extract oil concentration at 0% (w/w), 2% (w/w), 3% (w/w), 5% (w/w), 7% (w/w), and 10% (w/w) to weight of grain maize and exposed days. Repellency effect was also conducted at 6, 12 and 24 h at different concentration oil. The number of weevil's death increases significantly as exposed time increases. The extracted oil by the three-solvent fraction had direct repellent and toxic effect to the weevil. From all treatment applied, extracted by methanol fraction had showed highest percentage mortality (74%). The lowest mortality rate was observed in ethyl acetate fraction oil (26%), at 2% (w/w) concentration. The effect of lantana Camara leaf powder and extracted oil on repellency and mortality was showed directly proportional to concentration dosage.</p>
Data from: Effective population size of Culex quinquefasciatus under insecticide-based vector management and following Hurricane Harvey in Harris County, Texas
<div> <em>Culex quinquefasciatus</em> is mosquito species of significant public health importance due to its ability to transmit multiple pathogens that can cause mosquito-borne diseases, such as West Nile fever and St. Louis encephalitis. In Harris County, Texas, <em>Cx. quinquefasciatus</em> is a common vector species and is subjected to insecticide-based management by the Harris County Public Health Department. However, insecticide resistance in mosquitoes has increased rapidly worldwide and raises concerns about maintaining the effectiveness of vector control approaches. This concern is highly relevant in Texas, with its humid subtropical climate along the Gulf Coast that provides suitable habitat for <em>Cx. quinquefasciatus</em> and other mosquito species that are known disease vectors. Therefore, there is an urgent and ongoing need to monitor the effectiveness of current vector control programs. In this study, we evaluated the impact of vector control approaches by estimating the effective population size of <em>Cx. quinquefasciatus</em> in Harris County. We applied Approximate Bayesian Computation to microsatellite data to estimate effective population size. We collected <em>Cx. quinquefasciatus</em> samples from two mosquito control operation areas, 415 and 802, during routine vector monitoring in 2016 and 2017. No county mosquito control operations were applied at area 415 in 2016 and 2017, whereas extensive adulticide spraying operations were in effect at area 802 during the summer of 2016. We collected data for eighteen microsatellite markers for 713 and 723 mosquitoes at eight timepoints from 2016 to 2017 in areas 415 and 802, respectively. We also investigated the impact of Hurricane Harvey's landfall in the Houston area in August of 2017 on <em>Cx. quinquefasciatus</em> population fluctuation. Although we did not detect significant effects of vector control interventions, we found considerable influences of the winter season and a major hurricane on the effective population size of <em>Cx. quinquefasciatus</em>. The fluctuations in effective population size in both areas showed a significant seasonal pattern. Additionally, the significant population expansion following Hurricane Harvey in 2017 supports the necessity for post-hurricane vector-control interventions.</div>
Data from: Fecundity of diamondback moth females when offered honey with pyridalyl, a selective insecticide
<p class="MsoNormal"><span>We previously reported that the presence of pyridalyl, a selective insecticide, in aqueous honey (50 % v/v) negatively affects the survival of diamondback moth (<em>Plutella xylostella</em>: DBM) adults. However, it remains unclear whether toxicity of pyridalyl in aqueous honey affects the fecundity of adult female DBMs. We analyzed the survival and fecundity of adult DBM under the water, honey, or honey + pyridalyl conditions in glass tubes</span><span> containing Japanese mustard spinach (</span><em><span>Brassica rapa</span></em><span>: Komatsuna) leaves</span><span> for 10 days. The survival of adults under the honey (50 % v/v) and honey + pyridalyl (100-fold dilution) conditions was significantly higher and lower, respectively, than under the water condition during the experimental period. The number of eggs laid by DBM females each day (fecundity) under the water condition was significantly lower than that under the honey condition throughout the experimental period, except on day 1. In contrast, the numbers under the water, and honey + pyridalyl conditions were not significantly different, except on day 2 (the honey + pyridalyl condition was significantly lower). To study the effects of plants grown in pots on the survival and fecundity of DBM females, we conducted experiments using acrylic cages containing potted komatsuna plants. The survival trends under the honey, and honey + pyridalyl conditions in the cages were similar to those in the glass tubes. Fecundity was evaluated based on the total number of subsequent generations (DBM larvae and pupae) on day 10. The numbers were significantly higher in the honey condition than in the water condition. </span><span>In contrast, the number in the honey + pyridalyl condition was not significantly different from that in the water condition. Based on these findings, the possible use of pyridalyl in honey for the biological control of DBM is discussed.</span></p>
JAK/STAT signaling regulated intestinal regeneration defends insect pests against insecticidal proteins produced by Bacillus thuringiensis
<p><span>A variety of coordinated host-cell responses are activated as defense mechanisms against pore-forming toxins (PFTs). <em>Bacillus thuringiensis</em> (Bt) is a widely used biopesticide whose efficacy and precise application methods limit its use to replace synthetic pesticides in agricultural settings. Here, we analyzed the intestinal defense mechanisms of two lepidopteran insect pests after intoxication with a sublethal dose of Bt PFTs to find out potential target genes for reduction of defense responses using dsRNA to silence their expression. We show that larval intestinal epithelium was initially damaged by the PFTs and that </span><span>larval survival</span><span> was observed after intestinal epithelium regeneration</span><span>. Further analyses showed that the proliferation and differentiation of intestinal stem cells after Bt </span><span>toxins</span><span> treatments were regulated through JNK and JAK/STAT signaling pathways. Repression of intestinal regeneration by treating specific dsRNA led to increased toxicity of Bt PFTs to both <em>Chilo suppressalis </em>and Spodoptera<em> frugiperda</em>. Consequently, a nano-biopesticide was designed to improve pesticidal efficacy based on the combination of dsRNA-nanoparticles with </span><span>Bt</span><span> bacterial strains. This formulation efficiently controlled insect pests suggesting its potential use to reduce the use of synthetic pesticides in agricultural settings for pest control. </span></p>
