Abstract
The changes in glycogen levels depending on starvation, feeding, aging and parasitisation in the mature female of Pimpla turionellae L. (Hymenoptera: Ichneumonidae), which is a biological control agent, have been observed. Glycogen level, which is a major energy source in insects, increased when the females of P.turionellae are fed with 30% honey, but it decreased depending on aging, starvation and parasitism. There was a positive relationship between the glycogen level of an insect and the number of its eggs laid within the host pupae.
Özet
Bu çal›flmada, biyolojik mücadele ajan› bir böcek olan Pimpla turionellae L. (Hymenoptera: Ichneumonidae)’n›n ergin diflilerinde açl›k, beslenme, yafll›l›k ve parazitlemenin glikojen seviyelerine etkileri araflt›r›ld›. Böceklerde önemli bir enerji deposu olan glikojenin P.turionellae’n›n diflilerinde %30’luk bal ile beslenmeye ba¤l› olarak artt›¤›, açl›k, yafllanma ve parazitleme durumlar›nda ise azald›¤› saptand›. Böce¤in glikojen seviyesi ile konak puplar›na b›rakt›¤› yumurta say›s› aras›nda do¤ru orant›l› bir iliflki oldu¤u belirlendi.
