Laboratory studies were carried out in Egypt on the biology of the fig pest Silba virescens Macq. Egg hatch was highest at 25 deg C. The larval stage (3 instars) lasted 7.3 days at 30 deg C, and the pupal stage 33.4 days at 15 deg C and 21.3 days at 20 deg C. Adult emergence was highest at 25 deg C and 75% RH, and the sex ratio was 1:1. Copulation occurred most frequently about 3 days after emergence. About 96% of eggs were laid in groups under the 1st 3 layers of scales surrounding the aperture of small unripe fruits. Figs 1-2.5 cm in diameter and 8-15 days old were the most preferred for oviposition. Field observations indicated that there were 6 generations a year.1 aAwadallah, A., M.1 aKira, M., T.1 aEl-Borollosy, F., M.1 aHashem, A., G.  uhttps://lonchaeidae.myspecies.info/some-biological-aspects-fig-fruit-fly-silba-virescens-maquart
