Susceptibility of the brown stink bug, Euschistus serous (Say), and the spined soldier bug, Podisus maculiventris (Say), to acetamiprid, cyfluthrin, dicrotophos, indoxacarb, oxamyl, and thiamethoxam, was compared in residual and oral toxicity tests. Generally, susceptibility of P. maculiventris to insecticides was significantly greater than or not significantly different from that of E. servus....

The present study is a summary of the current level of the insecticide resistance to selected organophosphates, pyrethroids, and neonicotinoids in seven Indian field populations of Bemisia tabaci genetic groups Asia-I, Asia-II-1, and Asia-II-7. Susceptibility of these populations was varied with Asia-II-7 being the most susceptible, while Asia-I and Asia-II-1 populations were showing significan...

Beet armyworm, Spodoptera exigua (Hübner), and fall armyworm, Spodoptera frugiperda (J. E. Smith), are occasional pests of cotton, Gossypium hirsutum (L.), and soybean, Glycine max (L.) Merrill. These insects can be difficult to control due to insecticide resistance and larval behavior on plants. The objectives of these studies were to determine the efficacy of selected insecticides against nat...

Insecticide susceptibility tests were conducted on five mosquito species collected from two localities in the Jordan Valley (Deir Alla and Ghor as Safi) in 2014. Diagnostic concentration of Temephos (0.25mg/L) was used against the larvae, while diagnostic concentrations of Deltamethrin (0.025%) and Lambdacyhalothrin (0.03g/m2) were used against the adults. The procedures of WHO were followed. A...

The ubiquitous use of agrochemicals is one driver for the ongoing loss insect biomass and diversity. Data show that field-realistic concentrations neonicotinoid insecticides can negatively affect both population density fitness solitary bees. However, underlying mechanisms these effects remain poorly understood. Here, using an established semi-field experimental set-up Osmia cornuta as a bee mo...

Changes in the susceptibility and detoxifying enzyme activity were measured in laboratory strains of Banks grass mite, Oligonychus pratensis (Banks), and twospotted spider mite, Tetranychus urticae Koch, that were repeatedly exposed to three insecticides. Three strains of each mite species were exposed to one of two pyrethroids, bifenthrin, and lambda-cyhalothrin, or an organophosphate, dimetho...

Pyrethroids are powerful insecticides used in the vector control program with impregnated mesh, and residual indoor sprays. However, resistance to insecticide reduces effectiveness. The present susceptibility study carried out against theAnopheles Stephensi monitor sensitivity conditions of An. vector, which raises need understand state Dungarpur region Rajasthan, India order better report vect...

OBJECTIVE The multidrug resistance (MDR) 1 gene encodes a membrane transporter called P-glycoprotein, which plays an important role in protecting cells against lipophilic xenobiotics by way of an ATP-dependent cellular efflux mechanism. Among children enrolled in the Northern California Childhood Leukemia Study, we examined the susceptibility conferred by MDR1 single nucleotide polymorphisms (S...
