Abstract

The behavioral inhibitory effect of methanol extracts from neem leaves (Azadirachta indica A. Juss) at different concentrations (0, 10,000, 18,000, 32,000 and 56,000 ppm) was evaluated using naïve and experienced medflies (Ceratitis capitata (Wied.)) ovipositing on the fruits of grape cv. ‘Italia’. The grapes were immersed in the specific treatments and were exposed for 24 h to 3 pairs of female and male medflies, both naïve and experienced, in a choice test. At concentrations a 18,000 ppm, the extract that was applied to the grapes inhibited oviposition. The previous experience with treated grapes did not affect the response of the medflies. This study is the first step toward the application of the behavior control of the medflies as a tool in grape vineyards. The potential for using oviposition inhibitory in behavioral control of C. capitata are discussed.
