Efficiency of plant induced volatiles in attracting <i>Encarsia formosa</i> and <i>Serangium japonicum</i>, two dominant natural enemies of whitefly <i>Bemisia tabaci</i> in China

Abstract

The present results indicate that RJA- and SJA-induced plant volatiles have higher efficiencies in attracting the natural enemies of whitefly B. tabaci. The attractive efficiencies varied according to the plant volatiles that JA induced, and also depended on the natural enemy species. The parasitoid E. formosa seems to be more sensitive to and attracted by the induced volatiles than the predator S. japonicum.
