Abstract:

In order to understand the biological characteristics of Anoplophora glabripennis adults in different hosts and develop the science of ecological control measures. We studied the weight, longevity, fecundity and hatching rate of A. glabripennis Motschulsky. on maples Acer negundo (AN), Salix matsudana f. lobato-glandulosa (SM), Populus alba var. pyramidalis (PA), and Fraxinus chinensis (FC). The results showed that host plants had some effects on weight of female and not significant effect on weight of male. The longevity of adult feeding on AN was the longest (female: 40.5 d, male: 32.2 d), whereas that on FC was the shortest (female: 14.4 d, male: 11.4 d). The longevity of adult on AN and SM were significantly higher than those on PA and FC. The fecundity of adult female feeding on AN was the largest (46.6 eggs), while that on FC was the lowest (8.9 eggs). The fecundity of female adult on AN and SM were significantly higher than those on PA and FC. These data showed that the host plants had a significant effect on adult longevity and fecundity. The egg hatching rate among four kinds host plants were not significant, and this indicated that the host plant had little effect on egg hatchability. An overall comparison of performance on the four plant species indicates that AN and SM were the most suitable host plant for A. glabripennis, while PA and FC were common host plant for A. glabripennis.
