%X The oviposition period of white wax insect is the key period of white wax production.The species and numbers of its natural enemy were investigated in the 10 main production areas in the oviposition period of white wax insect.The results showed that there were 15 natural enemy species of white wax insect in the 10 communities.The dominants were \%Microterys ericeri\% Ishii.\%M.sinicus\% Jiang,\%Tetrastichus kodaikanalensis\% Saraswat,\%Anthribus lajievorus\% Chao and \%Chilocorus rubidus\% Hope.The aggregation index was relatively low in the 10 communities,but the diversity index and evennes index were high.The highest coefficient of community similarity was 97.46%,and the lowest coefficient was 75.92%.The main factors interfering with community similarity were the production area,ecological environment and different numbers of the dominants in different community.The 10 communities were divided into three groups by a systematic clustering analysis and two\|dimensional ordination.The first group is in the production area of the female white wax insect,the number of its natural enemy were relatively few.The second is in the production area of white wax,where the natural enemy number was much more than the first group.The third is in production area of both female white wax insect and white wax,the dominant natural enemy number was between the 1st and 2nd groups.The natural enemy harm of white wax insect is an important factor to cause that the white wax can not produce female seed insect.in some production areas.
