Sublethal effects by deltamethrin and spinosad on the grain weevils Sitophilus zeamais and S. granarius
… context, we evaluated the sublethal effects by deltamethrin and spinosad on two species of grain weevils (Sitophilus zeamais e S. granarius). In the first experiment, we evaluated the insecticide effect of deltamethrin and spinosad on survival, walking activity, irritability and different …

Characterization of the Increased Risk of Attention Deficit Hyperactivity Disorder Following Early-Life Exposure to Deltamethrin
… the mechanism through which the pyrethroid deltamethrin (DM) contributes to the development of ADHD. Our studies identify perturbations in voltage-gated sodium (Nav) channel 1.6 and medium spiny neurons which highly express Nav1.6- both of which are key components of reward circuitry. These …

Transcranial Doppler sonography: a new noninvasive method for measuring toxicant-induced alterations in cerebral blood flow
… to the commonly used pyrethroid insecticide deltamethrin. Deltamethrin has previously been shown to increase CBF in rats as determined by other techniques. In this experiment, deltamethrin was dissolved in glycerol-formal solvent and administered intravenously at dosage levels of 5% and 10% …

Long-term effects of insecticides on environmental health: How does exposure of a female egg-laying insect to an insecticide affect subsequent generations?
… varied greatly depending on the pyrethroid (deltamethrin, cypermethrin) and neonicotinoid (thiacloprid, imidacloprid, thiamethoxam) they were topically exposed to, and that sublethal doses may take time to have an effect. Furthermore, males appeared to be more sensitive, with reduced …

Insecticide-Mediated Neurochemical and Behavioral Changes as Possible Predisposing Environmental Factors in Idiopathic Parkinson's Disease
… insecticide heptachlor or the pyrethroid deltamethrin. Results were compared to those induced by the established parkinsonian neurotoxicant, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). At the end of the treatment period, mice were assessed for effects on behavior, as well as …

Assessing chemical control options and their effects on lesser clover leaf weevil, red clover pollinators and evaluating red clover seeding rates for optimal seed production and N fixation in Saskatchewan, Canada
… evaluate the effectiveness of the insecticides deltamethrin and cyantraniliprole in controlling LCLW in red clover in both field and laboratory-based evaluations, as well as to assess potential impacts on the bee community. The second objective was to determine the optimal red clover seeding …

Pest Management of Japanese Beetle (Coleoptera: Scarabaeidae) and a Study of Stink Bug (Hemiptera: Pentatomidae) Injury on Primocane-bearing Caneberries in Southwest Virginia
… (JB) activity on primocane-bearing caneberries. Deltamethrin, chlorantraniliprole, bifenthrin, lime-alum, and thyme oil reduced JB activity in the field. Deltamethrin, chlorantraniliprole, acetamiprid, an azadirachtin and pyrethrin mixture, an azadirachtin and neem oil extract mixture, and an …

Molecular characterization and functional analysis of cytochrome P450 genes in the yellow fever mosquito Aedes aegypti (Diptera: Culicidae)
… insecticides (permethrin, cypermethrin and deltamethrin) resulted in either down or up-regulation of these transcripts. Functional analyses of the selected P450 transcripts were conducted by using RNA interference (RNAi) followed by insecticide bioassay. RNAi was achieved by feeding mosquito …

Flea Beetle Populations and Their Management on Vegetables in Virginia
… highest yield in cabbage and eggplant. Lastly, deltamethrin-incorporated mesh row covers were evaluated and shown to provide excellent control of FB compared to an untreated row cover or a control; and comparable to the standard insecticide, dinotefuran. This research helps vegetable growers to …
