... tolerance/resistance in phosphine-tolerant populations. The level of total esterases, carboxyl esterases, 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 collec...

...mine the toxic effect of phosphine on microsomal enzymes (NADPH-Cytochrome P450 reductase (NADPH-CPR), ethylmorphine-N demethylase and aniline 4-hydroxylase) and soluble protein contents of a wheat grain pest, Trogoderma granarium collected from godowns of Punjab, Pakistan. Six populations of khpara beetle with different levels of susceptibility to phosphine were used in this study. Based on LC50...

...nt of resistance against phosphine in stored grain insect pests in Pakistan is the result of whole godown improper fumigation of bagged wheat over the past several years. Trials were conducted in 338 godowns in 8 districts of upper Sindh. Out of these, 169 godowns were selected for fumigation with phosphine inside and under polyethylene sheets, while the others for indoor space fumigation in godowns without covering wheat st...

...eus) were tested against phosphine and bio fumigants to check their fitness and potential following by F1 generation. Phosphine fitness in term of mortality mean calculated at 300 ppm was minimum against weevil but highly effective against red flour beetle after 24hours while, at 400ppm showed same resistance level in all. At 500ppm, lesser grain borer (LGB) was more susceptible as compared to others as in rice we...

...against deltamethrin and phosphine. Results indicated significant difference between lab and field collected pests strains regarding their resistance mechanisms to deltamethrin as well as phosphine treatments. Field strains collected from various geographical locations were observed more resistant then lab strains. Calculated LC50 values was very less in field strains as compared to lab strains. Maximum mortality of lab and...
