Abstract
The present study was conducted to survey and count the population density of parasitoids on crucifers aphid infesting cabbage plants in Egypt and, Iraq during the two seasons 2019-20 and 2020-21. Three parasitoids, one primary D. rapae and two hyperparasitoid, Pachyneuron sp. andAlloxysta sp., were recorded. Diaeretiella rapae was highly dominant (91.37 and 88.39%) in Egypt and (94.00 and 91.03% )in Iraq during the 2019-20 and 2020-21 seasons. The highest parasitism rate in Egypt was 92.39% recorded in the 2019-20 season and 95.65 % in the 2020-21 season. Meanwhile, in Iraq it was77.78% recorded in the 2019-20 season while it was 53.33 % in the 2020-21 season. The life cycle of D. rapae was 17.43±0.91 days at 18.00°C ±1°C and 65 ±5RH%. The sex ratio (Female: Males) was 2.47 :1. By rearing D rapae for two generations, the sex ratio was almost 1:1 in two generations. This investigation may be helpful in implementing the use of parasitoids as biological control agents in integrated pest management programs for aphids on cabbage.
