The egg parasitoid, Trichogramma brassicae Bezdenko (Hymenoptera: Trichogrammatidae) is the most important and widely distributed species of Trichogramma in Iran. It attacks eggs of several lepidopterous pests, and is a major biological control agent. Rearing parasitoids is necessary for experimental work, and, potentially, for mass release in the field. Selecting a suitable host is critical fo...

To enhance biological control of insect pests in greenhouses, facilities and procedures for mass production of the parasitoids, Eretmocerus sp., Encarsia formosa, and Trichogramma brassicae, and the predator, Aphidoletes aphidimyza were successfully developed in Hengshui, Hebei province, China. Mass production of the aphelinid wasps was achieved by using different plant varieties and host insec...

The paper describes the monitoring of phytosanitary conditions in different regions Almaty region (Kazakhstan) and demonstrates large population cruciferous fleas (Phyllotreta cruciferae) on rapeseed plants, which reaches 7-9 spec./m2, exceeding economic injury level (3-5 spec./m2). disease is observed to spread wheat barley seeds. Proceeding from this, study aims develop effective protection m...

Host-foraging responses to different intra- and interpatch densities were used to assess three Trichogramma spp. (Hymenoptera: Trichogrammatidae) Trichogramma deion Pinto and Oatman, T. ostriniae Pang and Chen, and T. pretiosum Riley - as potential biological control agents for the Indian meal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae). Single naïve females were allowed 6 h to ...
