The performance of five insecticides (bendiocarb, deltamethrin, DDT, malathion, and imidacloprid) using three application methods (oil-based insecticide films on filter paper, and acetone-based insecticide deposits on two substrates: filter paper and glass) was assessed against a susceptible strain of Cimex lectularius (L.) and two resistant strains of Cimex hemipterus (F.). Substrate type sign...

The effects of 0.001, 0.01, 0.1 and 0.5 ppm concentrations of malathion, an organophosphorus insecticide, viewed over the course of the experiment, on adult emergence and sex ratios of emerging adults of the parasitic wasp, Pimpla turionellae L. (Hymenoptera: Ichneumonidae) were investigated. Diets which contain 0.001 and 0.01 ppm malathion significantly increased the total adult emergence on d...

Ground applied ultralow volume spraying is part ofthe integrated pest management program undertaken by the Saginaw County Mosquito Abatement Commission, and as such, is subject to scrutiny of its effectiveness in the program. For several years, the Commission relied almost exclusively on ultralow volume (ULV) malathion in the adulticiding program but always had problems effectively controlling ...

Understanding how ecological interactions mitigate the impacts of perturbations such as pesticides in biological communities is an important basic and applied question for ecologists. In aquatic ecosystems, new evidence from microcosm experiments suggests that submerged macrophytes can buffer cladocerans from pulse exposures to the widely used insecticide malathion, and that mitigation increase...

to determine the degree of susceptibility of an. sacharovi to malathion 5%, fenitrothion 1% and ddt 4% extended studies were carried out on sucked blood engorged mosquitoes collected from dasht argen (fars province) in 1997. testing method was according to standard who method in lots of 25 adults' mosquitoes in 4 replicates. an. sacharovi were touched by malathion 5% and ddt 4% insecticides in ...

OBJECTIVE To define the insecticide resistance status of Triatoma infestans to deltamethrin (pyrethroid), malathion (organophosphate) and bendiocarb (carbamate) in Bolivia. METHODS Fifty populations of T. infestans were sampled in Bolivian human dwellings. Quantal response data were obtained by topical applications of 0.2 μl of insecticide-acetone solutions on nymphs N1 of the F1 generations....

Pesticides have an innate capacity to cause damage to biological system. Considering above fact the present study deals with the effect of the insecticide malathion on histological and biochemical study on cardiac muscle tissue in Channa punctatus. In present study effect of sub lethal concentration (0.8 ppm) of malathion on protein, lipid and glycogen content and histopathological changes in h...

Features of pesticide synergism and acetylcholinesterase (AChE) inhibition (in vitro) were studied using a selected range of organotin compounds against the early 4th instar larvae of a highly resistant strain of the diamondback moth (DBM), Plutella xylostella, a major universal pest of cruciferous vegetables.Fourteen triorganotin compounds were evaluated for their ability to enhance the toxici...

Vector resistance to insecticides is becoming a major obstacle to malaria prevention measures. A baseline survey was carried out in Khartoum city, Sudan, during September-November 2007, to map the insecticide susceptibility status ofAnophelesarabiensis and to examine the correlation with insecticide usage in urban agriculture. Susceptibility tests were conducted in 6 sentinel sites representing...
