Abstract

Alpha-cypermethrin, indoxacarb, and lufenuron insecticide residues were studied in oranges and tangerine after their application in open fields in Egypt. This was done using QuEChERS for extraction and clean-up, the integration of technology with HPLC and GC equipments. When validating a method for the analysis of insecticides in commodities, there are certain criteria that must be met. These include linearity range, limit of quantitation (LOQ), and accuracy regarding precision and dependability.  In our testing, we found that the recovery rates of the method at different fortification levels (0.01, 0.1, and 1.0 mg/kg) ranged from 91% to 103% for the insecticides used in both crops. Results showed that the zero time (initial) of alpha-cypermethrin, indoxacarb, and lufenuron in orange were 2.55, 1.88, 3.1, and 2.67, 1.92, and 3.4 ppm in tangerine. The percentage of losses in residues was greater in tangerine than orange. The half-lives of Alpha-Cypermethrin, indoxacarb, and lufenuron were 2.4, 4.2, and 4.71 days in orange and 2.5, 4.6, and 5.69 days in tangerine. Contaminated orange and tangerine could be consumed safely after two-week treatment. Conclusively, from these results it could be concluded that the percentage of losses in residues was greater in tangerine than orange, andcontaminated orange and tangerine could be consumed safely after two-week treatment.
