Bionomics of Dactylispa approximata on Lophatherum gracile
Abstract:Through field investigation,bionomics of Dactylispa approximata,a new recorded leaf miner on L.gracile in Jiangxi was systematically studied in this paper.Mine characteristic,adult and pupa morphology and life history of D.approximata were described.A theoretical basis and technical support were provided for the forecast and control of D.approxirnata on L.gracile. Key words:leaf—mining insect;mine;morphology;life history;Dactylispa appraximata;Lophatherum gracile
