Major Research Interests

• Evolutionary biology, including systematics, molecular phylogeny and evolution, developmental biology of Hymenopteran parasitoids, especially the family Braconidae;

• Physiological interaction between parasitoids and host insects with particular reference to the molecular mechanism underlying the regulation of the host larvae by parasitoids;

• Biological control of insect pests using parasitoids;

• Plant quarantine and invasive biology of exotic insect pests;

• IPM of agricultural insect pests;

• Bio-safety of transgenic crops.

Research Activity

Parasitoid wasps (Insecta: Hymenoptera) constitute one of the most specious groups of terrestrial organisms with probably 1 million species worldwide (the majority as yet undescribed, especially in China). They are of major importance in both natural ecosystems and agriculture and forestry. Some of them have been exploited in many successful biocontrol enterprises. My research on parasitoid wasps used to cover from systematics (taxonomy and phylogenetics), morphology and ultra-structure, biodiversity, biogeography, development of parasitoid immature stages, investigation and evaluation of parasitoids of insect pests, to utilization of parasitoids as biological control agents in both IPM and biological control programs in China.

Since 1990¡¯s, this focus has been expanded to understand speciation, molecular phylogeny and evolution of parasitoids, and co-evolution of parasitoids and their hosts. We have been sequencing 16S rRNA, 28S rRNA, and cyt b genes of a large number of parasitoid species in China and analyzed the molecular phylogenies of Braconidae, both at subfamily and generic levels. Using the diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae), as host, we have also been conducting research on physiological interaction between host and its three parasitoid species (each having the different kinds of associated factors, such as venom, polydnavirus (PDV) and teratocyte) and the molecular mechanism underlying the regulation of host larvae by parasitoid-associated factors.

In recent years we have also been conducting applied research on plant quarantine, insect pest management, and bio-safety of transgenic crops. We have been cooperating with the University of Queensland in Australia on the project ¡°Quarantine Decision Support and Training Aids for China and Australia¡± supported by ACIAR, and a web-based system for both domestic and international plant quarantine in China has been developed and accessible via http://qpm.8866.org. We have been launching several programs (both national and provincial levels) on the recently invaded insect, the super-bug, Bemisia tabaci (Hemiptera) in Zhejiang, China with particular reference to its parasitoids and biocontrol. We have identified several newly recorded insect pests from the urban ecosystem and analyzed the new trends for the occurrence of insect pests in the current urban ecosystem in China. In last five years the citrus borer, Agrilus auriventris Saunders (Coleoptera), had caused serious loss on citrus production in the citrus growing area in the southeast China, therefore we are now focusing on an IPM project incorporating with basic research results, from both our own or the literature, into practice to develop and improve the pest management system in citrus gardens against this pest. We have also been carrying out research on the bio-safety of transgenic Bt cotton and rice, especially the impact on the natural enemies and insect community since 1998.
