| Abstract: | The pathogen Capnodium sp.causes a serious sooty mold disease on Lagerstroemia indica in Guiyang.The Disease Index(DI)goes to the highest in October.The occurence of the disease is closely related to the populution of two insect species Eriococcus lagerostroemiae Kuw(Eriococcidae) and Tinocallis kahawaluokalani (Kirkaldy)(Aphidoidea,Callaphidae).The correlation coefficient(r)and the linear regression equation(y=a bx)between the disease and two insect species were given. |
