in this research, the effect of entomopathogenic fungus, beauveria bassiana (ascomycota, hypocreales), on functional response (in laboratory) and reproduction (in microcosm) of parasitoid wasp, aphidius matricariae haliday (hym.: braconidae) on its host, myzus persicae (sulzer) (hem.: aphididae) was investigated. illustrating number of mummified aphids versus initial density of green peach aphi...

the aphidiine parasitoids (hym., braconidae) attacking the pest aphids on various pome and stone fruit trees in different parts of iranwere studied. a total of 13 species belonging to seven genera of aphid parasitoids were identified in association with 17 aphid species on 10 different species of fruit trees. sixty nine tritrophic associations were detected from the studied area of which 25 ass...

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...

Heritable symbionts are common in insects with many contributing to host defence. Hamiltonella defensa is a facultative, bacterial symbiont of the pea aphid, Acyrthosiphon pisum that provides protection against the endoparasitoid wasp Aphidius ervi Protection levels vary among strains of H. defensa that are differentially infected by bacteriophages named APSEs. By contrast, little is known abou...
