Distribution area and natural parasitism of Apanteles brunnistigma Abdinbekova (Hymenoptera: Braconidae) on the olive leaf moth
Abstract :Olive leaf moth, Palpita unionalis
H�bner (Lepidoptera: Carambidae) is an important pest in olive groves in
Mediterranean countries. It feeds on leaves, shoots, and later green fruits of
olive trees. The native larva parasitoid Apanteles
brunnistigma Abdinbekova (Hymenoptera: Braconidae) was found a solitary
endoparasitoid on P. unionalis in the
eastern Mediterranean and southeastern Anatolia regions. In this study, the
distribution and natural parasitism by A.
brunnistigma on P. unionalis were
determined in seven provinces (Adana, Gaziantep, Hatay, Kahramanmaraş, Kilis,
Osmaniye, and Mersin of Turkey). P.
unionalis larvae were collected all provinces over its period of occurrence
from May to December. The collected larvae were reared until adult parasitoids
or moths emerged in the laboratory. The parasitism rate and the number of A. brunnistigma per P. unionalis larva were estimated for each grove. A total of 2903 P. unionalis larvae were collected for
two years. The
highest natural parasitism rate (58.3%) was
observed in Gaziantep and (30%) in Hatay. The
parasitism was observed in “summer” (during the period of June through
December), with a mean of 9.2-17.6% in 2014-2015, respectively.These findings highlight the need for improved
biological control of P. unionalisthrough introduction, augmentation and releasing of the solitary
parasitoid A. brunnistigma
