ABSTRACT
Damaging effect of two species of gall midges (Diptera: Cecidomyiidae) have been investigated on Castanopsis hystrix Miq. (Fagales: Fagaceae) in Pubei County of Guangxi, China were investigated from December 2012 to December 2013. Jaapiella sp. damaged leaves, while Contarinia sp. damaged stems and leafstalks. The damage ratio and the index of Jaapiella sp. in December 2012, March, July and December 2013 were 9.7±2.0%, 14.8±1.9%, 24.1±1.5%, 12.3±0.6% and 25.6%, 31.3%, 35.6%, 26.2%, respectively, while those of Contarinia sp. were 33.2±3.4%, 38.4±4.3%, 43.2±3.1%, 31.6±3.5% and 29.6%, 30.9%, 36.0%, 30.9%, respectively. The results will provide essential information to develop strategies that can be used for their control.
