Newly optimised and validated LC-MS/MS methods have been used for the quantification of pesticide residues in larvae samples. Analysis showed that DELTA and TEB are retained by larvae, even after 24 h of fasting, due to their lipophilicity. Larvae fasting period allowed the elimination of 47% ...

The individual urine was collected during 24 h after administration and samples were analysed by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). DON was rapidly excreted within 24 h, the total DON recovered (free DON + DON glucuronides) was 64.0 ± 22.8% of the ...

Smallest value of intrinsic rate of increase (rj occurred at LC_(50) (0.0393 females/female/ day) while the highest value (0.0539) was at control. Overall larval development was significantly reduced to 18.0 days with LC_(50) opposed to 24.1 days at control. Pupal period was shortened to ...
Daily fecundity rate was significantly greater (200 females/day) in the control than 126 in LC20 (5.13 mg/L). Potential fecundity was lowest (179 females/female/generation) with LC50 treatment than 675 in the control. Smallest value of intrinsic rate of increase (rm) occurred at LC50 (...
The larvicidal bioassay tests indicated that the mixture from the degradation reaction showed LC 50 increased significantly ( P < 0.05). This is the first report demonstrating deltamethrin metabolism by chymotrypsin.doi:10.1016/j.tiv.2008.05.007Qinggui Yang...
