Abstract: To explore predatory capacity and biocontrol potential of Nesidiocoris poppiusi Carvalho, the functional response and searching efficiency to Myzus persicae, Bemisia tabaci and Frankliniella occidentalis, were investigated under laboratory conditions. The results indicated that the functional response of both females and males fitted with the Holling Ⅱ model. The females showed a high voracity to M. persicae, B. tabaci and F. occidentalis, with the estimated maximum daily predation rates of 123.5, 133.3 and 192.3 individuals, respectively, while the males displayed much less rates of 43.3, 19.6 and 22.1 individuals, respectively. The instantaneous attack rates of the females on M. persicae, B. tabaci and F. occidentalis were 1.065, 1.037 and 0.810, respectively, and those of the males were 1.184, 1.129 and 0.853, respectively. The handling time of the females for M. persicae, Bemisia tabaci and F. occidentalis was 0.0081 d, 0.0075 d and 0.0052 d, respectively, shorter than the counterpart of the males. The search efficiency of N. poppiusi for the three pests decreased with increasing prey density. N. poppiusi had higher search rates for M. persicae and B. tabaci than F. occidentalis, and the downward trend of the males was larger than that of the females. The results suggest the high potential control ability of N. poppiusi adults against the three pests and provide valuable information for its application in agriculture.

Key words: Nesidiocoris poppiusi, Myzus persicae, Bemisia tabaci, Frankliniella occidentalis, functional response, searching efficiency
