...cide mixture (endosulfan+chlorpyrifos) in peripheral blood erythrocytes of freshwater fish, Oreochromis niloticus by using Comet assay. The 96-h LC50 value of pesticide mixture was estimated for 180-old fingerlings of O. niloticusin a static system and then four sub-lethal concentrations viz. 1/3rd of LC50, 1/4th of LC50, 1/5th of LC50 and 1/6th of LC

...i.e., bifenthrin and chlorpyrifos, on the consumption rate of web weaving spider Cyrtophora citricola, was observed. Live spiders for the study were collected from citrus orchards of Sargodha and maintained individually in the laboratory. Both the control and insecticide treated spiders were offered larvae of Drosophila melanogaster in different densities. C. citricola increased prey consumption as the prey density was increased. Insec...

...rasitism was recorded in chlorpyrifos treated plots. We conclude from this experiment that for the management of C. partellus, Imidacloprid is recommended as it exhibited high level of selectivity for T. chilonis parasitization capacity. However, further investigation is needed to study the effect of these chemicals on the whole life cycle of T. chilonis.

...25, 0.75 and 1.25ppb) of chlorpyrifos administered for 96 h has been studied on hematological and seral biochemical components of Oreochromis mossambicus. RBCs, Hb and Hct decrease significantly (p < 0.05) indicating an anemic condition, while the WBCs and platelet counts increased significantly (p < 0.05) in all the treated groups compared to the control group. Among the seral biochemical parameters, the level of blood glucose, cortisol and cholesterol ...

...an) and organophosphate (chlorpyrifos) investigated on the activity of antioxidant enzymes viz. superoxide dismutase, peroxidase, catalase and glutathione S-transferase in different organs (liver, gills, kidney, brain, heart and muscle) of fish, Labeo rohita. The LC50 of chlorpyrifos+endosulfan mixture was calculated as 1.95±0.02 μgL-1 for 96 h with the 95% confidence limits. The fish e...

...cypermethrin, abamectin, chlorpyrifos, thiamethoxam and bisultap on toxicity against 1st-6th instar larvae in Phauda flammans Walker (Lepidoptera: Zygaenidae) were tested using the leaf-dipping method. Meanwhile, effects of these pesticides on detoxifying and protective enzymes in P. flammans larvae were also measured. Results showed that the LC50 value of beta-cypermethrin, abamectin, chl...
