This article provides information on the influence of biotic and abiotic factors development population orchard agrobiocenosis woolly apple aphid (Eriosoma lanigerum Hausm), main sucking pest seed orchards.

Insect pests are soft-bodied and tiny creatures with plant sap sucking habits that devastate various agricultural crops, fruit trees, ornamental plants several vegetables. To control these insect four IPM techniques were used in tomato field an aim to minimize the use of synthetic pesticides. Five colours sticky traps (yellow, green, blue, black red), different light trap (red, yellow, green wh...

Plants employ diverse responses mediated by phytohormones to defend themselves against pathogens and herbivores. Adapted pathogens and herbivores often manipulate these responses to their benefit. Previously, we demonstrated that Turnip mosaic virus (TuMV) infection suppresses callose deposition, an important plant defense induced in response to feeding by its aphid vector, the green peach aphi...

A laboratory model system with the rosy apple aphid (Dysaphis plantaginea Pass.) on apple seedlings was developed to study the effects of homeopathic preparations on this apple pest. The assessment included the substance Lycopodium clavatum and a nosode of the rosy apple aphid. Each preparation was applied on the substrate surface as aqueous solution of granules (6c, 15c, or 30c). Controls were...

Pecan foliage is attacked by three species of aphids [Monellia caryella (Fitch), Melanocallis caryaefoliae (Davis), and Monelliopsis pecanis Bissell], resulting in damage that can reduce tree nut yield. In this study, we assayed the ovipositional response of the green lacewing Chrysoperla rufilabris (Burmeister) to M. caryella and M. caryaefoliae at high and low aphid densities and the developm...
