Abstract:

The host choice action of Anoplophora glabripennis was studied in different analog mixed forest of Ailanthus altissima and Populus bolleana. The result showed that the effect of the types of the mixed forests on the beetle's host choice was significant. Along with the reducing of individuals of P. bolleana in the mixed stands, the landing and mating frequencies of the beetle were reduced, but the total landing frequencies of some types of mixed stand were invariably. Mating action of the beetle mainly occurred on the individuals of P. bolleana in analog stands. According to the analog stand experiment result, the two insect resistance mixed stand types (mixed proportion was 3∶2 or 2∶3) were acquired.
