Food characteristics strongly regulate digestive enzymatic activity of insects through direct influences on their midgut mechanisms. Insect performance is better on diets that contain nutrients in proportions that fit its digestive enzymes. Little is known about the influences of rearing history on parasitism success of Habrobracon hebetor Say. This research focused on the effect of nutrient re...

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...

Eicosanoids are oxygenated metabolites of three C20 polyunsaturated fatty acids, mainly arachidonic acid (AA; 20:4n-6), but also 20:3n-6 and 20:5n-3. Aside from their importance in biomedicine, eicosanoids act in invertebrate biology. Prostaglandins (PGs) influence salt and water transport physiology in insect rectal epithelia and in Malpighian tubules. PGs also influence a few insect behaviors...
