Abstract:

To explore the control potential of the mirid bug Nesidiocoris tenuis in vegetable pest management, the predation and preference of N. tenuis to three vegetable insect pests were tested via non-choice and choice experiments in the laboratory. The non-choice experiments showed that the predation of N. tenuis male adults on Bemisia tabaci adults, 1st-2nd instar nymphs of Myzus persicae and 2nd instar larvae of Plutella xylostella were 15.6,11.2 and 13.2, respectively. The highest predation was found on B. tabaci, which was significantly higher than the others. In choice experiments, N. tenuis preferred to feed on B. tabaci adults, followed by the 2nd instar larvae of P. xylostella and 1st-2nd instar nymphs of M. persicae. The results showed that for the three common pests in vegetable, N. tenuis could be preferentially used for the biological control of B. tabaci.

Key words: Nesidiocoris tenuis, Bemisia tabaci, Myzus persicae, Plutella xylostella, predation preference
