Survey and distribution density of genus Brachymeria species (Hymenoptera : Chalcididae)‎ in Egypt

Abstract EN

Surveys of Brachymeria (Hymenoptera: Chalcididae) parasitoids attack larvae and pupae of Lepidoptera, Diptera and Coleoptera were conducted in the Egypt between 2014 and 2018.

The population density of Brachymeria was counted in Egypt.

Data on distribution of 12 Brachymeria wasp species provides.

In this study, field experiments were undertaken during 2014 and 2016 seasons in Monoufia, Qalubiya and Giza Governorates.

The obtained results indicated that pupae of Pieris rapae (Linnaeus) (Lepidoptera: Pieridae) and Earias insulana (Boisduval) (Lepidoptera: Noctuidae), were obtained.

The highest mean parasitism percentage was recorded at sowing during September 2014 and 2015 cabbage growing seasons (28.49% at 2014 and24.46 % in 2015) respectively by Brachymeria femorata (Panzer) (Hymenoptera: Chalcididae).

The highest mean parasitism percentage was recorded in Qalubiya Governorate during 2015 in cotton growing seasons (4.76%) followed by Giza Governorate during 2016 in cotton growing seasons (4.47%) by Brachymeria brevicornis (Klug) (Hymenoptera: Chalcididae).
