花椒潜跳甲生物学特性及防治试验

Biological characteristics and control experiment on Podagricomela shirahatai

本文报道了花椒潜跳甲 Podagricomela shirahatai(Chuj)在甘肃舟曲１年发生 ２代，以成虫港入树干基部３～５ｃｍ土层内或砂石缝中越冬，越冬成虫春季出土上树时是防治关键时期，成虫产卵前用５０％增效辛硫磷乳油和４０％氧乐果乳油１２００～１５００倍稀释液在成虫期和幼虫期喷洒叶面，杀虫率在９０％～９８．２％。不发生药害，效果显著。

It is found that Podagricomela shirahatai has two generations a year in Zhouqu County Gansu Province.In winter imagoes usually sneak into the ground 3 - 5cm around be trunk of Chinese Prickly ash to survive. It is high bine to control its density when imagoes come out from ground and climb up tree. The effective rate to kill imago or larva through spraying the surface of leaves with 1: 1200 - 1500 solution of Phovim (50% )or omethoate(40% ) and water is as high as 90% ~ 98.2% with little side effect.
