دراسة تأثير العائل الحشري في بعض الخصائص الحياتية للمتطفل Pristomerus vulnerator (Panzer, 1799)‎ تحت ظروف التربية المختبرية

Abstract EN

Laboratory experiments were conducted to rear the parasitoid pristomerus vulnerator (panzer, 1799) (hymenoptera : ichneumonidae : cremastinae) on larvae of three insect hosts fed on an artificial diet at the biological control studies and research center, Damascus university.

the parasitoid was reared on flour moth ephestia kuehniella, zeller,1879 (lepidoptera : pyralidae), apple codling moth cydia pomonella linnaeus (lepidoptera : tortricidae) and grapevine moth lobesia botrana (denis and schiffermüller, 1775) (lepidoptera : pyralidae), to select the most suitable host for the quantitative rearing of this insect parasitoid.

results obtained showed that the preferred host for rearing of this parasitoid in the laboratory was the second stage larvae of the apple codling moth.

the duration of the different stages and the whole generation on this host was shorter than that of the flour moth and the grapevine moth, the highest sexual ratio was recorded for individuals reared on the larvae of the codling moth, and the parasitism rate was the highest on the larvae of the codling moth, and the lowest mortality rate of the parasite was observed on the apple codling moth.

results of this study indicated that the laboratory rearing of the parasitoid in large commercial scale is possible by using the larvae of the apple codling moth as a host.
