“…Following treatment with the tested extract, the impairment of these enzymes reduced the relative growth rate. This is consistent with previous reports by Elbanhawy et al 33 and Kandi et al 34 , which linked the toxicity of tested oil to AST and ALT impairment. These results were consistent with our results which indicated that the treatments with nanoemulsion of mandarin crust oil, mandarin crust oil, nanoemulsion of marigold extract and marigold extract, at LC 50 reduced the activity of AST (Aspartate amino transaminase) and ALT (Alanine amino transaminase), compared to control.…”

Background and Objective: In recent years, nanoemulsions have been used to target pest toxicity due to the dangers of chemical pesticides. The current study investigated the insecticidal activity of the mandarin crust oil (Citrus reticulata) and marigold extract (Calendula officinalis L.) in the form of nanoemulsions formulations and plant oil against 2nd instars larvae of Spodoptera littoralis.(Boisduval). Materials and Methods: To assess the toxicity of treatments to 2nd instar larvae, the leaf-dipping technique was used. The toxicity was recorded after one, three, five and seven days post-treatment and LC 50 values were calculated. Results: The results indicated that nanoemulsion of plant oil extracts has the highest insecticidal activity against S. littoralis, followed by plant oil extracts. The major constituents identified by GC-MS analysis in marigold extract and mandarin crust oil were, 6-epi-shyobunol (Longiborneol) and D-Limonene, respectively. Furthermore, at LC 50 , all treatments decreased AST/GOT and ALT/GPT activity, showing a significant reduction in creatinine activity when compared to control. Conclusion: According to the current study, the use of the nanoemulsion formulation could be useful in integrated pest management programs.

Xanthogaleruca luteola (Mull., 1766) is the major defoliator pest of elm trees in urban area. In this study the effect of lufenuron on some biochemical and biological characteristics was investigated on X. luteola. The LC30 and LC50 of lufenuron were determined on the second instar larvae as 20.22 and 36.65 mg l-1, respectively. Effects of LC30 and LC50 concentrations of lufenuron on some biological parameters showed that lufenuron caused an increase in larval, pre-pupal and pupal developmental periods. Also, none of the female insects that emerged from the treated larvae did not spawn during their life. The LC50 concentration of lufenuron decreased carbohydrate, lipid and protein content and increased glycogen content. But there was not a significant difference in glycogen, and protein contents following the exposure to LC30 concentration. However, glutathione-s-transferase (GST) and esterase activities were significantly increased at LC50. In conclusion, due to lethal and sublethal effect of lufenuron on biochemical and biological traits of X. luteola, it can be recommended for control this pest in IPM program.
