摘要

The occurrence regularity of Phyllocnistis citreua in northern Guizhou was investigated,and the relationship between summer shoot controlling of citrus and occurrence of P. citreua was studied. The results showed that P. citreua occurred from May to September every year in northern Guizhou,and the occurrence reached the peak from early May to late June and from early July to late August. The occurrence in early and mid July was the most serious. The free-sprouting time had a close relationship with occurrence quantity and damage level of P. citreua. The earlier the free-sprouting time was,the greater the occurrence quantity and damage level of P. citreua was. The integrated control techniques focused on timely erasing summer shoots and controlling shoots were suggested to use in production,in order to control the occurrence of P. citreua.
