摘要

In the present study, fresh eggs of Plain Tiger butterfly, Danaus chrysippus (Linnaeus) were collected from the host in a net room. The fresh eggs were placed in a growth chamber under conditions of 25±1℃, 80±5% RH, and with a photoperiod of 14 hr of light and 10 hr of darkness. Hatching larvae were individually reared with either the semi-synthetic artificial diet as experimental group, or the leaves of host plant, Asclepias curassavica as control group until adult emergence. We observed the effect of growth and development with artificial diet on various development stages in this species. The results are summarized as follows. The survival rates of various development stages of larvae reared with the artificial diet are lower than the leaves of host plant group. All duration of various development stages of larvae of the experimental group was longer than that those of the control group. The above data of the two groups were analyzed with a t-test and showed a significant difference existed (p ＜ 0.05). And the duration of two groups during the pupa stage had a significant difference too. The head capsule width, body length of larvae, weight of pupa, wing length and width of the experimental group are less than that those of the control group, only the weight of adult of the experimental group slightly higher than the control group. The increment of the head capsule width of the larva was in accordance with the increase in the larval instar stage; it maintained a ration of 1.56 times in the experimental group and 1.55 times in the control group, approximately. In both group, the increment of body length of larvae was in accordance with the increase in the larval instar stage. Though the survival rate of this species reared with the semi -synthetic artificial diet was only half than that those with the host plant leaves, and the survival rate of the experimental group is still low. As each results of this experiment show the semi-synthetic diet still has some shortcomings need to be improved in the future. But in the present study, the exploitation of semi-synthetic diet on rearing butterflies has already a breakthrough.
