Sterilant and oviposition deterrent activity of neem formulation on Peach fruit fly Bactrocera zonata (Saunders) (Diptera: Tephritidae)
Journal of Biopesticides 1 (2), 177-181
Abstract: Impact of neem (600, 300, 150, 75, 37.5 and 18.7 ppm) on sterilant and oviposition activity was evaluated on the peach fruit fly Bactrocera zonata (Saunders) (Diptera: Tephritidae) under laboratory conditions using filter paper dip method. Results revealed that neem formulation has a significant effect against eggs of B. zonata at all concentrations used, compared with control. However no effect of neem on the sterilant percent and adults emerged from treated eggs at all concentrations. Moreover, the rate of eggs sterility which produced from treated adults with the previous concentrations was concentration-dependent and significant differences were existed when mated (treated females with normal male and treated female with treated male). While no significant differences observed in treated male mated with normal female. When compared with control (normal male with normal female). The repellency effect of neem on egg deposited in orange fruits after being sprayed with previous concentrations was high and reach to 5.0 % eggs/puncture/fruit, compared with 65.8 % of control. Moreover, the percent of egg hatch decreased to 76.2 % at 600 ppm, compared with 89.0 % of control.
