Alteration of carbohydrates metabolism and midgut glucose absorption in Gromphadorhina portentosa after subchronic exposure to imidacloprid and fenitrothion.

摘要: This study was undertaken to test the hypothesis that following exposure insecticides, changes take place in metabolism of carbohydrates and absorption midgut insects. The Madagascar hissing cockroach (Gromphadorhina portentosa) chosen for experiment as a model organism, due it being easy breed its relatively large alimentary tract, which important when preparing microperfusion bioassay. In each group cockroaches treated with imidacloprid fenitrothion, glucose, expressed area under curve (AUC), elevated compared control group. Glucose hemolymph examined insects present vestigial amount, often below threshold determination, so determinable carbohydrate indices were: trehalose concentration fat body glycogen content. level found exposed irrespective mixed into food, wer...
