تأثير نوع العائل النباتي لذبابة الفاكهة Ceratitis capitata في نسبة التطفل بالدبور Aganaspis daci

Abstract EN

The relationship between the host plant species of fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) and parasitism level of Aganaspis daci (Weld) (Hymenoptera: Figitidae) was investigated, depending on the host species fruit size and fruit infestation level by C.

capitata larvae.

The study was carried out during the period from May to October of 2015 in Amret area, Akkar plain, Tartous Governorate.

The results showed that the highest parasitism level of A.

daci was recorded form the larvae obtained from guava fruits (16.3%) followed by those from peach (13.1%), Valencia orange (8.7%), loquat (6.8%) and plum (6.3%), but there was no significant correlation between the fruit size and parasitism level.

Whereas, the relationship between fruit infestation level by C.

capitata larvae and parasitism level of A.

daci was positive (R2=0.62).

These results indicated that the parasitoid wasp A.

daci could play a positive role in the biological control of C.

capitata within integrated pest management along the Syrian coast.
