The second generation larva of Argyrogramma albostriata of 4th instar, which were fed in the lab with Solidago canadensis under the condition of room temperature and natural light, were used as material for the experiment of host specify. 104 plant species from 52 families were used in testing host specify and the herbivory of leaves of different plants and survival time were observed. The results show that leaves of Conyza canadensis, Aster subulatus, Kalimeris indica, Erigeron annuus and S. canadensis were eaten by A. albostriata after 24 hours, while other plants were not eaten until the larva were starve to death. Then the life history of A. albostriata fed on C. canadensis, A. subulatus, K. indica, E. annuus and S. canadensis were observed and the main indexes of life history were recorded. The main results are as follows. 1) Survival rates of A. albostriata fed on C. canadensis, A. subulatus, K. indica, and S. canadensis are higher than larva fed on E. annuus significantly. 2) Fed on different plants have different influence on the length of different instars of A. albostriata. 3) Pupation rate, emergence rate, longevity and pupation weight of A. albostriata fed on C. canadensis, A. subulatus, K. indica, and S. canadensis are higher than that fed on E. annuus. The results indicate that A. albostriata is oligophagous, only eat C. canadensis, A. subulatus, K. isindica, E. annuus and S. canadensis. A. albostriata can complete its life history on C. canadensis, A. subulatus, K. indica, and S. Canadensis. However, the growth of lava of A. albostriata is constrained when fed on E. annuus.
