Abstract: The predation of Coccinella septempunctata on tea aphids was studied for artificial breeding the predator for pest control in tea plantations. The 1^st to the 4^th instar larvae and juveniles from the 1^st generation of C. septempunctata raised on a forage that included bean aphids (Group A) or one exclusive of bean aphids (Group B) were placed in an enclosed chamber with released live tea aphids to monitor their preying patterns. The results showed that, when N→∞, the maximum daily counts on predated tea aphids by the 1^st to the 4^th instar C. septempunctata were 29.6930, 112.3571, 304.4702, and 552.0794, respectively, for Group A, while 30.7353, 94.6816, 305.1269, and 575.1551, respectively, for Group B. There was no significant difference shown between the two groups (p＞0.05, n = 6). On the other hand, the counts for the male and female adults from Group A were 187.3163 and 120.0344, but from Group B 499.5544 and 222.1254, respectively, displaying a significant difference between the groups (p＜0.01, n=6). Therefore, feeding C. septempunctata with the bean aphids-containing forage or bean aphids alone did not significantly affect the predatory behavior of the 1^st generation larvae. However, the adult males and females of Group B would devour tea aphids in much greater a number than those of Group A. The information would be of value for the biocontrol program on tea aphids.
