searching efficiency and handling time are two major components of functional response and are usually used to evaluate effectiveness of natural enemies. the effect of different foraging periods on the functional response of larval aphidoletes aphidimyza (rondani) (dip.: cecidomyiidae) feeding on third instar nymphs of aphis craccivora was studied. the experiment was conducted in terms of time-...

Most studies on chemical and biological control of arthropod pests of agriculture do not consider the effects of partial host plant resistance. We present research using two partially resistant and a susceptible cultivar of common cabbage (Brassica oleracea var. capitata L.) and determining specific effects of interactions between the host plants, one or two common crucifer aphids (Myzus persic...

Abstract Conservation biological control could be an alternative to insecticides for the management of aphid Myzus persicae (Sulzer). To develop sustainable strategies M. in peach orchards Mediterranean, a 2-yr field experiment was conducted identify key predators aphid; determine whether proximity insectary plants boost natural enemies comparison resident vegetation; and selected enhance enemy...

Abstract To improve exclusion systems for fruit trees, insect nets of various types were evaluated their permeability to different beneficial and pest species, under laboratory field conditions. Pests studied the apple maggot, Rhagoletis pomonella (Diptera: Tephritidae) spotted wing drosophila, Drosophila suzukii Drosophilidae). Beneficials Aphidoletes aphidimyza Cecidomyiidae), Aphidius matric...
