Abstract
Results indicated that the developmental periods of eggs, larvae, prepupal and pupal stages were 6.70, 14.75, 2.20 and 12.80 days at 20 ◦C and 65%RH, while it lasted 3.76, 8.80, 1.25 and 6.35 days at 30 ◦C and 65%RH. The longevity of female was 27.30 days, while the male longevity was 32.60 days at 21.6◦C and 67%RH. The longevity of female was 27.3 days, the male longevity was 32.6 days at 21.6◦C and 67%RH. The number of eggs/female ranged from 75 to 180 eggs. Concerning pheromone traps study, the highest peaks of male catches recorded in the first week of Dec. and in the first week of Nov. with 550 and 880 males /3traps for both two seasons, respectively. On the other hand, water pan trap was the most effective (406 males /trap) followed by modified palm weevil bucket trap (226/males/ trap). Also, the green traps caught the higher males compared with that of yellow, red and white colors but the means of all tested colors were not significantly different. Regarding the lure types, Tuta optima, lure was the highest efficient (252.8 males/trap), while the prepared locally lure was the lowest (39.4 males/trap) and the differences among means of the three lure types were significant. For periodicity of male catches during scootphase and photophase it found that the attraction was higher in the 1st hour of photophase than that of the 2nd hour where the trapped moths in the 1st hour represented 5.8 folds of that of the 2nd hour.
