Insecticide Resistance of a Field Strain of Mediterranean Fruit Fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in Egypt

Ismail Ragab El-Gendy

Background and Objective: Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is one of the most destructive insect-pests of vegetable and horticultural crops in Egypt. Conventional insecticides, especially malathion have been applied extensively to control this pest. The present study aimed to monitor whether the field-strain of C. capitata has developed a resistance to certain insecticides mostly used in the field to control this pest. Materials and Methods: The study was conducted under laboratory conditions on the 2nd generation of the wild flies of C. capitata. Feeding bioassay of malatox, malathion, fenitrothion and spinosad pesticides was assayed at 24 and 48 h post-treatment. All data were statistically subjected to the LDP line program. Results: Bioassay results proved occurrence of resistance of C. capitata to the tested insecticides, with a moderate to very high level of resistance in male flies ranged from 24.24-115.56 fold and females ranged from 18.79-112.81 fold, 24 h post-treatment. Resistance factor increased to high level of resistance in males; 89.19-100.8 fold and moderate to high level in females; 29.34-99.45 fold, 48 h post-treatment. Conclusion: The results showed that the least resistance insecticide was recorded with malathion for C. capitata males and females at 24 h. In this study, resistance levels found her are considered a good indicator of possible field control failures if one of the tested products is used. Thus, this study suggests that resistance management programs must be planned in control this pest.
