Abstract
The peach fruit fly, Bactrocera zonata S. is a species that can cause important economic losses to various fruit species, with more than 50 host plants. In this study, repellent and oviposition deterrent effects of methanol (Mx), ethanol (Ex) and distilled water (Dx) extracts of moringa bark and leaves, cinnamon, peppermint and ginger were evaluated at different concentrations (10, 20 and 30%) against B. zonata adults. The experiment was carried out by using free choice test. Among all extracts, peppermint (Pm) extracts (Pm-Mx, Pm-Ex and Pm-Dx) delivered important repellent activity at the maximum dosage (30%), i.e. 0.50, 0.75 and 0.50 mean number of adults, respectively; while, the minimum repellent activity was observed in moringa bark of all three extracts. Correspondingly, all extracts have oviposition deterrent effect but Peppermint (Pm) extracts (Pm-Mx, Pm-Ex and Pm-Dx), deliver the best effect. The present investigation revealed that bio-active extracts can be used as alternative cost-effective, safe, and environment-friendly insecticides for the effective management of B. zonata in order to reduce the ecological hazards caused by traditional chemical pesticides.
