His research interests lies in : 1 ) insect fungal pathogenesis and strain improvement by genetic modification ; 2 ) fungal conidiation , conidial germination and dimorphism 研究领域： 1 ）昆虫病原真菌致病机理和基因工程研究； 2 ）真菌孢子发育和形态转换的分子机理研究。

Infectivity and virulence of millet culture . the 7 - day - old broomcorn millet culture was bioassayed against m . persicae nymphs by exposing aphids to conidial showers at 9 different concentrations ( 0 . 4 - 50 . 1 conidia / mm2 ) 由此可见，在所测试的因素中，湿度和温度对黍米培养物产抱的影响最为明显，而光照影响较小。

Based on modeling of the resultant time - dose - mortality data , the estimates of lc50 for the culture against the aphid species were 3 . 0 , 1 . 7 , and 1 . 2 cominia / mm2 on days 5 - 7 after exposure to conidial shower ; the estimates of lt50 dropped from 4 . 6 days at the concentration of 4 . 5 conidia / mm2 to 3 . 2 days at 26 . 3 conidia / mm2 . all aphid cadavers exhibited typical pandora syndrome . thus , the millet culture of p . delphacis was highly virulent to m . persicae , suggesting an applicability of the easy and convenient millet culture method to entomophthoralean fungi 用第1 、 5及9代黍米培养物对桃蚜2一3龄若蚜分别进行30min的单剂量抱子浴接种试验，均表现很强的侵染力，各代培养物的实际接种剂量分别为25 . 2个抱子/ mmz 、 18 . 7个抱子/ mmz和21 . 0个抱子/ mmz ，对桃蚜的lt50分别为3
