Abstract
The woolly apple aphid Eriosoma lanigerum (Homoptera: Aphidiae) is an important pest of apples around the world. Since the withdrawal of certain broad-spectrum insecticides from use, E. lanigerum has become one of the most important pests in apple growing regions. Currently , the effective management of the blood-red toad population is based on a good synergy between chemical methods of control and biological management of beneficial insects, especially through its main unique natural enemy, the parasite Aphelinus mali (Hymenoptera: Aphelinidae). Detailed monitoring data of both types were collected in the field (Almaty region) for ten years (2010-2020) to develop a Knowledge-Based Decision Support System. The flights of Aphelinus mali began before the flowering of apples in the garden and continued at least until the end of the flight of the second generation . E. the emergence of important stages in the cultivation of lanigerum, such as the beginning of wool formation or spring activity, and the transition of reptiles from colonies to flower clusters or shoots, was carefully monitored. All the information obtained was compared with historical and literary data and analyzed in a phenological model of population dynamics. Our results are based on the developed model of the first generation adult A. it was assumed that the appearance of mali (important for the first parasitic activity and the basis for the continuation of the offspring of A. mali in the continuation of the season) can be accurately predicted. Therefore, this information can be used to stop spraying insecticides with harmful effects at this point, as the results of field tests show. In addition, E. the beginning of migration of lanigerum reptiles to flower clusters or new shoots is accurately predicted by the model.
