تأثير درجات الحرارة و كثافة المضيف المختلفة في الكفاءة التطبيقية و الأداء الحياتي للمتطفل Bracon hebetor Say

Abstract EN

Parasitism efficacy and biological performance of Bracon hehetor Say at different temperatures and densities of host larvae were investigated.

The results showed that the parasitoid female in spite of its ability to paralyze host larvae at all densities but it was not able to lay eggs at 14± 1°C.

While at temperatures of 26 and 35 ± 1SC it was able to paralyze their host larvae and laying eggs which were developed to larvae and pupae.

Finally the parasilism efficacy and biological performance of the parasitoid B, hebetor were increased as a result of increasing its larva) host.
