板栗(Castanea mollissima Blume)为山毛榉科栗属植物,是中国栽培最早的经济树种和重要干果之一,也是中国出口创汇的重要干果之一[1]。但中国板栗主要栽培于山地、丘陵地带,地理环境复杂,加之在生产上管理粗放,常遭受多种害虫的危害。目前,全国共记载鞘翅目、鳞翅目和半翅目等板栗害虫共计10目118科823种[2]。
网蛾科幼虫以取食植物叶片、蛀食植物茎和枝干生活,取食寄主有板栗、榛子、核桃、石榴等20科22种[3],其中板栗昆虫共记载5属17种,即树形拱肩网蛾(Camptochilus aurea Butler)、黄带拱肩网蛾(Camptochilus reticulates Moore)、枯叶拱肩网蛾(Camptochilus semifasciata Gaede)、金盏拱肩网蛾(Camptochilus sinuosus Warren)、蝉网蛾(Glanycus foochowensis Chu et Wang)、黑蝉网蛾(Glanycus tricolor Moore)、蜂形网蛾(Hyperthyris aperta Leech)、中线赭网蛾(Rhodoneura atristrigulalis Hampson)、直线网蛾(Rhodoneura erecta Leech)、中带网蛾(Rhodoneura midfascia Chu et Wang)、中带褐网蛾(Rhodoneura sphoraria Swinhoe)、中褶网蛾(Rhodoneura mollis yunnanensis Chu et Wang)、银线网蛾(Rhodoneura yunnana Chu et Wang)、叉斜线网蛾(Striglina bifida Chu et Wang)、二点斜线网蛾(Striglina bispota Chu et Wang)、曲线网蛾(Striglina curvita Chu et Wang)、一点斜线网蛾(Striglina scitaria Walker)[2,3]。2013-2014年对罗田县各栗园板栗害虫进行调查时新发现3种网蛾卷叶危害,本研究对其幼虫形态学特征及生活习性进行了描述,并拍摄了成虫及其雌雄外生殖器、幼虫及其卷叶习性的照片,以供栗农和板栗工作者快速识别鉴定。
1 材料与方法
2013-2014年先后从罗田县大崎乡、三里畈、白庙河、大河岸、河铺镇、白庙河等栗园板栗树上发现3种网蛾卷叶危害,将其幼虫连同卷叶带回实验室饲养,获取成虫,在解剖镜下对其雌雄外生殖器进行解剖制片,根据成虫和外生殖器形态结构特征(图1)对3种网蛾进行鉴定。……
