...ases, choline esterases, acetylcholine esterases and aryl esterases were determined in 4th & 6th instar larvae and adult beetles of phosphine-tolerant populations (previously exposed to phosphine for 15 years) of wheat grain pest, Trogoderma granarium collected from various storage facilities of Punjab, Pakistan viz., Mandi Bahauddin-I, Mandi Bahauddin-II, Gujrat, Gujranwala and Sargodha. The activities of all esterases ...

...le of saponins on insect acetylcholinesterase (AChEs). The enzyme activities were tested for the effect of saponins. The AChE activity of T. castaneum was inhibited by the saponins and follows competitive inhibition kinetics. In case of A. mellifera enzyme activity was not inhibited. In vitro and in vivo inhibition was observed for T. castaneum at larval stages, in dose dependent and time dependent manner. LC50 was det...

...terases, cholinesterase, acetylcholinesterase, arylesterase and carboxylesterase in 4th, 6th instar larvae and adult beetles of deltamethrin-resistant populations’ viz., Gujranwala, Okara and D.G. Khan was significantly increased as compared to susceptible population of T. granarium (population never exposed to any kind of insecticide/fumigant since 2001). Different developmental stages possessed different levels of es...

...y HPLC. The toxicity and acetylcholinesterase activity of selected venom fractions were determined using of Musca domestica adults. Only one fraction (out of 7) from H. tamulus venom and one fraction (out of 5) of A. finitimus venom were selected on the basis of their maximum yield. The approximate molecular weights of these selected venom fractions were determined by SDS Gel electrophoresis. The molecular weight of venom fractions of H...
