摘要：竹蝉在浙江省为 6a1代 ,若虫于地下吸食竹子鞭、根的汁液 ,以卵在竹上枯枝中和各龄若虫在土下越冬。成虫发生在 6月底、7月初到 9月上中旬 ,刺吸竹、树枝汁液为补充营养 ,有扑灯、鸣叫习性 ;7～ 8月在竹上已死 2～ 3年的枯竹枝上产卵 ,每产卵孔中有卵 12～ 2 1粒 ,卵于下年 7月上旬孵化。若虫 5龄 ,生活于土下 5～ 4 0 cm深的竹鞭两侧 ,每穴 1虫 ,虫穴与地面有垂直的通气孔 ;若虫性好斗 ,两虫相遇 ,常争斗致伤或致死。天敌较多 ,重要的有竹蝉卵旋小蜂 ,3 8.3 %～ 4 1.4 %的产卵孔中发现有旋小蜂的幼蜂 ,1头幼蜂可食竹蝉卵 2～ 4粒。竹蝉履甲取食若虫 ,挖掘 50 0余头老熟若虫于室内饲养 ,若虫被食率 2 8.71%～ 3 2 .58%。蝉花菌也寄生若虫 ,经 5a调查 ,寄生率为3 2 .5%～ 3 7.8%。防治竹蝉可采取加强竹林管理、挂枝诱成虫产卵。
Platylomia pieli Kato ,an underground bamboo pest,completes the development of one generation in 6 years in Zhejiang,with eggs and nymph overwintering on dead branches and in soil respectively.Adults occur through late June or early July to mid September,feeding on branches of bamboo and other tree species by sap sucking .Eggs,12～21 eggs per hole,are laid in dead,2～3 year old branches,and hatch in early July of the following year.The nymphal stage has 5 instars.They live in soil with 5 to 40 cm in depth,and feed on bamboo roots.Nymphs live individually,and are aggressive and attack each other when two or more of them meet ,leading to heavy wounds or death.Platylomia pieli is rich of natural enemies ,of which the wasp,Eupelmus sp.,is the most important,and its larvae destroys 38 3%～41 4% Platylomia pieli eggs. Sandalus sp.,another key enemy,kills 28.7%～32.58% P.pieli larvae.Isaria cicadae Maquel is the main nymph parasitic fungi.
