Abstract:
Bactrocera dorsalis Hendel is an invasive pest
widely distributed in Asia and the Hawaiian Islands that causes serious damage
to fruit and vegetable crops. The prevention
and control of B. dorsalis mainly
relies on chemical insecticides but extensive use of these has not only caused
different degrees of resistance to emerge in B. dorsalis populations,
but also kills the natural enemies of this pest, making control progressively more difficult.
Biological control is an important alternative to pesticides for the control of B. dorsalis. Currently more than 70
species of parasitic natural enemies of B.
dorsalis have been identified in China and abroad. Predatory natural
enemies are mainly ants, earwigs, rove
beetles, mites, spiders and birds, whereas parasitic microorganisms are mainly
fungi, bacteria, nematodes and symbiotic bacteria. Deploying multiple
biological control agents is generally preferable to a single agent. This paper systematically and comprehensively
categorizes the available domestic and foreign natural enemies of B.
dorsalis, and assesses the potential of using individual species or multi-species
combinations for the biological control of this pest.
