| Abstract: | As one of the dominant species of predatory mites in citrus orchards, Amblyseius eharai Amitai et Swirski is widely distributed in citrus production areas in China. The indiscriminate use of chemical pesticides is harmful to a large number of natural enemies of spider mites, while the drug resistance is increasing year by year. The use of natural enemy organisms to control spider mites has become an important green control measure for citrus pest mites in recent years. In this paper, the predatory ability and selectivity of A. eharai on three orchard pests, including Panonychus citri McGregor, Dialeurodes citri Ashm and Thrips hawaiiensis Morgan, were investigated. The results showed that, A. eharai could prey on about 18.5 larva and nymphs of P. citri, 13.9 nymphs of D. citri, and 10.4 nymphs of T. hawaiiensis within 24 h at 28℃. The functional responses to these three prey species were of Holling II type. The predation efficiency of A. eharai is highest at 28℃, but much higher or lower temperature will reduce the predation ability. While P. citri, D. citri and T. hawaiiensis exist at the same time, A. eharai would preferentially prey on P. citri, accounting for 82.14% of the prey taken. Female adult A. eharai are selective for feeding on all developmental stages of the P. citri, and their larva and nymph are the preferred stages. Our study shows that A. eharai has strong potential to control P. citri, D. citri and T. hawaiiensis, which provides a theoretical basis for the field application of A. eharai. |
