| Abstract: | Results of field investigations conducted in main citrus growir.g areas of Gaizhou Province during 1985-198S indicated rhat U. yananensis was attacked by 12 species of predators, 5 species of parasitoids, and 2 fungal pathogens. The dominating natural enemy species differed in different citrus groves. For example, in Nanjie Citrus Orchard, Aphytis yanonensis Hym.:Aphelinidae] had the highest population density of 10 per leaf at its peak in October. Chilocorus bijugus Col.:Coccinellidae] had 3.4/leaf in August. In Xiaoshan Citrus Orchard, the population density of A. yanonensis in October was 2.5/leaf. C. hupehamis and Cybocephalus nipponicifs Col.:'Nitidulidae] had low numbers of less than 0.5 per branch throughout the year. |
