【摘要】 大竹缘蝽 (N otobitus excellens Distant,缘蝽科 Coreidae)在云南新平一年发生一代。成虫于竹包衣内与绿竹缘蝽 (Cloresmue Pulchellus)、狭竹缘蝽 (N.elongates Hsiao)等混聚越冬。若虫严重危害龙竹 (Dendrocalamus giganteus Munro)新笋。越冬期成虫及发笋期若虫空间分布型为聚集分布。印楝素防治若虫效果较好 ;并可在聚集高峰期采用相应的人工防治措施。更多还原

【Abstract】 Notobitus excellens Distant has one generation annually in Xinping County, Yunnan Province. Adults spend winter in bamboo shoot sheath living with Cloresmue Pulchellus Hsiao and N. elongates Hsiao . During bamboo shoot period, nymphs attack and do harm to the newborn shoots of the host bamboo Dendrocalamus giganteus Munro seriously. Their peaks of population gathering were observed. The biopesticide azadirachtin was used to control the nymphs efficiently. Among the methods of IPM, silvicultural way has the fundamental function. Artificial methods should be carried out correspondingly.更多还原
