Abstract:

Larvae of Argyrogramma albostriata Bremeret Grey feeding on Solidago canadensis were found in China, this research was to determine the host range of insect. Insect larvae collected in the field were fed, observed, identified and ascertained the life history in the laboratory. The author investigated the plants in sites where insects were found and other areal area of S. canadensis in Hefei. Host range tests with 13 representative plant species from 6 families. Artificially feeding them S. canadensis, they could complete their life history only on S. canadensis, new generation of larvae also could feed on it. Surveys and feeding habits studies showed that their host plants were all in compositae: such as Kalimeris indica, Conyza canadesis, Erigeron annuus, Aster subulatus and S. canadensis. When above five species of plant existed simultaneously, S. canadensis were eaten preferentially. S. canadensis had become the constant part of host range of Argyrogramma albostriata Bremeret Grey. Their primary host was weeds, it’s advantageous to the prevention and control of S. canadensis.
