Trichogramma parasitoids are the most widely used biocontrol agents and play a crucial role in biological control of agricultural forest pests. Many studies have shown that feeding on carbohydrate rich diet can effectively improve their egg laying capacity longevity. However, few reported impact carbohydrate-rich parameters different species parasitoids. In this study, we compared differences b...

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...
