Abstract: The rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae) was reported in India during 2016. Biological control of RSW plays an important role in Integrated pest management (IPM). Therefore, the study was undertaken to determine the distribution of native predator species and their potential against this invasive pest in the key coconut-growing regions of Tamil Nadu. Totally nine species of predators belonging to different insect orders viz., Coleoptera, Neuroptera and Hymenoptera were recorded on A. rugioperculatus. It was interesting to note that the Mallada desjardinsi and Chrysoperla zastrowi sillemi were more abundant in all the regions. To determine the neuropteran predators as potential biocontrol agents, the biology and life table parameters of C. zastrowi sillemi and M. desjardinsi on RSW were studied in the laboratory. M. desjardinsi seemed to have the maximum developmental period and total longevity of both female and male (23.44 ± 0.83, 41.63 ± 0.86 and 35.22 ± 1.23 days) relative to C. zastrowi sillemi (20.29 ± 0.18, 34.64 ± 0.74 and 30.58 ± 0.89), respectively. The net reproductive rate (Ro)113.7 ± 0.21females/female/generation and mean fecundity (F) 224.25 eggs/female was observed maximum in M. desjardinsi than C. zastrowi sillemi. Both of the neuropteran predators could complete their life cycle on RSW, illustrating that the invasive whitefly is a suitable substrate for the development of these neuropteran predators. Thus, the present study clearly indicates the effectiveness of neuropteran predators and paves the way for the development of novel techniques for the management of invasive RSW through the release of chrysopid predators.
