| Abstract | ||
| The latent effect of some pesticides belonging to different chemical groups on certain biological aspects of Ceratitis capitata adults emergeing from treated pupae was studied under laboratory conditions. All the tested toxicants affected significantly fecundity of females and egg hatchability. The tested compounds induced female sterility of 62.07, 72.07, 77.69, 50.25, 28.43 and 54.94% for chlorfluazuron, fenamiphos, fenobucarb, oxamyl, pirimiphos-methyl and pyriproxyfen, respectively. The longevity of both males and females was affected significantly. The mean longevity of males and females emerging from treated pupae were 4.80-10.13 and 6.12-16.18 days compared with 11.50 and 16.84 days for the control, respectively. Field chemical control trials were conducted in citrus orchard by applying partial bait-spray. All treatments achieved good control for the pest. Treatment of one branch in all rows was more efficient compared with the other treatments. ❑imethoate reduced the population of files by 84.89 and 79.56%, and the reduction of fruit infestation was 71.47 and 81.51% in 1990 and 1991, respectively. Pirimiphos-methyl caused reduction of population by 82.46 and 70.84% and the infestation was reduced by 59.11 and 70.94% in 1990 and 1991, respectively. | ||
