Abstract

The experiments were carried out in laboratory at Plant Protection Institute, Sharkia branch, Sharkia Governorate during 2013-2014 seasons. The results indicate that the female of D. rapae accepted all stages of the cabbage aphid B. brassicae. The number of parasitoid adults emerged from the mummies of B. brassicae was significantly greater on the third and fourth instars than that obtained from the first and second instars. The highest average of parasitism was in the second instar. On the other hand, host relationship between the parasitoid D. rapae and B. brassicae, impact of males on the number of progeny of the parasitoid reared on different host plants was conducted. The results revealed that with the increase of parasitoid density the percentage of parasitism raised in cabbage followed by cauliflower and radish. The presence of males caused considerable decrease in the efficiency of the parasitoid females. This decrease reached its minimum on the three crops. The highest percentages of parasitism reached were 36.2%, 28.2% and 25.8% at eight females only/Petri dish Meanwhile; the percentages were 30.8%, 25.8% and 21.4% at 8♀+8♂ (females with males). The number of aphid offspring emerged per parasitoid female decreased with increasing of parasitoid density. The number of offspring emerged per parasitoid female was adversely affected by the presence of males.
