“…After the three months, all animals were sacrificed. Fasting blood samples were collected by puncture of the sublingual vein and left for clotting then, centrifuged at 3000 rpm for 15 min to separate serum for liver and kidney function tests [[6], [7], [8]]. Biochemical parameters were determined in serum using Biodiagnostic kits (Bio diagnostics Co., Egypt).…”

“…These results were in agreement with those obtained by Barrania (2002). This indicates that the toxic potential of these pesticides for the tested organism is greater when present in a mixture than in an individual (Tiwari, et al 2019). Several reports on the interaction of drugs and insecticides with AChE appeared.…”

The toxicological effects of some insecticide mixtures (chlorpyrifos, pyridalyl, chlorantraniliprole, emamectin benzoate, and methoxyfenozide), against the 3 rd instar of Spodoptera larvae were evaluated. The results indicated that, LC 50 values for each insecticide were 12.44, 0.88, 0.08, 0.16 and 3.35 mg L-1 respectively, and 0.458, 0.009, 0.0014 and 0.357 mg L-1 respectively.Also, the LC 50 values of chlorpyrifos are increased by larvae weight increased. LC 50 values of chlorpyrifos as a function of postfeeding initiation of Spodoptera larvae to pyridalyl, chlorantraniliprole, emamectin benzoate, and methoxyfenozide after two days (single exposure) were 1.33, 1.99, 0.74, and 0.37 mg L-1 respectively. Therefore, post-feeding initiation of larvae to previous insecticides tremendously decreased LC 50 values of chlorpyrifos.Also, the percent inhibition of AChE from Spodoptera head capsules by chlorpyrifos, pyridalyl, chlorantraniliprole, emamectin benzoate, and methoxyfenozide (LC 10 equivalent concentrations) were 44.5, 23.4, 19.4, 33.5, and 15.4%, respectively. The percent inhibition of AChE from Spodoptera head capsules by chlorpyrifos either pre-treatment or post-treatment with pyridalyl, chlorantraniliprole, emamectin benzoate, and methoxyfenozide were increased. This indicates that the toxic potential of these pesticides for the tested organism is greater when present in a mixture than in an individual.

“…Agricultural soils and even public playgrounds are frequently contaminated by pesticide mixtures [ 38 ]. Pesticides can have greater toxic effects in mixtures than when they are tested individually in earthworms [ 39 ] and other animal species such as chicks [ 40 ], salmon [ 41 ] or on mammalian bone marrow erythrocytes in CD-1 mice [ 42 ]. Recent scientific studies have highlighted the need to test real-life exposure scenarios [ 43 ].…”
