英文摘要	To explore sustainably effective biological control measures to suppress the super pest Bemisia tabaci (Gennadius) Middle East-Asia Minor 1 and better understand the biological control effects of single and multiple releases of parasitoids, we evaluated the performance and interaction of two aphelinid parasitoids of B.tabaci, Eretmocerus hayatiZolnerowich & Rose (an exotic primary parasitoid) and Encarsia sophia (Girault & Dodd) (an autoparasitoid, which is controversial in a biological control program). Single species or two species were jointly (1:1 density ratio) released in field cages on cotton in Hebei province, China, in 2010. Results of the field cage experiment showed that all parasitoid release treatments were successful in reducing the densities of the host B.tabaci relative to the control in which no parasitoid was released. The combined release of two parasitoid species showed the highest control effect among the treatments. Different population growth trajectories indicated asymmetric competitive effects of En.sophia on Er.hayati. The densities of Er.hayati were significantly higher in the Er.hayati alone treatment than in the combined release treatment, while densities of En.sophia were lower in the En.sophia alone treatment than in the combined release treatment. Our results demonstrated interspecific competition between autoparasitoid En.sophia and exotic primary parasitoid Er.hayati. However, no evidence indicated that autoparasitoid En.sophia disrupted the host suppression achieved by primary parasitoid Er.hayati. The release of the autoparasitoid together with the primary parasitoid may not influence host suppression in biological control.
