| Abstract | ||
| Occurrence and distribution of the Pumpkin or cucurbit Fruit Fly, Dacus &lotus Loew as re-appearing pest on Cucurbitaceae were studied in addition to its biology. D. cillatus was found in ten Egyptian governorates from 2002 till 2004, causing serious damage for gourd, marrow, cucumber, cantaloupe, melon and luf. Larvae as well as adults were reared under laboratory conditions of 25 ± 2°C and 65+ 5% R. H. on marrow fruits. The mean durations for eggs, larval and pupal stages were 3.0 ± 0.8, 7.3 ± 2.7 and 9.3 ± 1.9 days, respectively. Adult insects fed on sugar, protein hydrolyzed and water lasted alive from 14 to 45 days. Copulation occurs with begging of night, female deposited S22.6 eggs, hatched and complete to give adults have sex ratio 1:1 and the total generation lasted 73.6 days. | ||
