Feeding ethanol extracts of seed kernel of Melia azedarach L., leaves of Lantana camara L., bulbs of Allium sativum L. and corms of Curcuma longa L. and one commercial Azadirachta indica formulation (Neem Baan 300 ppm) at 1, 2 and 3% concentration to fruit fly adults (Bactrocera tau) resulted in delayed egg laying in comparison to control. The egg laying started from 13th to 15th day onwards in different treatments in comparison to control where egg laying was observed from 11 to 12th day onwards. The flies fed on A. indica formulation (Neem Baan) showed significantly higher inhibitory effect on oviposition (7.3 eggs/female/day) followed by C. longa and M. azedarach both being at par with an average of 10.6 and 10.9 eggs/female/day, respectively. The inhibitory effect increased with the increase in concentration of test materials, the maximum being at 3% concentration. Egg hatch also decreased significantly in all the treatments and was directly proportional to the concentration of plant extracts. A. sativum proved best with minimum egg hatch (27.9%) followed by A. indica (44.7%) and M. azedarach (51.9%).
