Abstract
The present experiments were conducted at the experimental farm belonging to the faculty of agriculture, Mansoura University. The squash plants (var. Eskandrani) was cultivated in the beginning of the third week of March, the first week of June, and the second week of August during the two successive seasons (2014 and 2015). The cotton aphid, Aphis gossypii recorded the highest relative abundance in March plantation during the first and second season of study (53.7 and 55.6 %, respectively) followed by Thrips tabaci (21.9 and 19.3 %, respectively). On the other hand, the potato leafhopper ranked the last category during the first and second season and represented by 2.3 and 2.1 %, respectively. While, the snake cucumber beetle Hensoepilachna argus did not occurred during the two seasons. In June plantation, A. gossypii recorded the highest relative abundance during the first and second season (39.4 and 26.6 %, respectively) followed by H. argus (20.9 and 24.3 %, respectively). While, in August plantation, H. argus ranked the first category during the first and second season and represented by 33.8 and 44.6 %, respectively. Moreover, during the two seasons, June plantation harbored the highest total numbers of the main pests and represented by 4590 and 3673 pests, respectively. The cotton mealybug, Phenacoccus solenopsis and the cotton whitefly Bemisia tabaci recorded the highest average number in August plantation during the two seasons with non-significant differences for P. solenospis and significant differences for B. tabaci. The snake cucumber beetle, H. argus recorded the highest average number for all stages in August plantation during the two seasons with non-significant differences during the first season and with significant differences during the second one.
