【摘要】 油菜叶露尾甲是在安徽省油菜田发现的一种新害虫,之前,在中国仅甘肃、青海有分布。田间调查、试验表明,该虫在安徽省年发生2代,主要危害期在每年的3-5月份。每年3月份,越冬成虫出土取食冬油菜花蕾和叶片,并在叶片上产卵危害,幼虫孵化后潜食油菜叶片危害,老熟幼虫入土化蛹、羽化,成虫有越夏、越冬习性。叶露尾甲喜凉不喜热,山区发生较重,也可危害白菜、甘蓝等十字花科蔬菜,近年来,在油菜上危害有加重的趋势。在防治上应以消除越冬虫源、蕾花期综合控制为宜,水旱轮作对其发生危害有较好的控制作用。
【Abstract】 Strongyllodes variegatus is a new insect pest of oilseed rape in Anhui Province.This pest was only distributed in Gansu and Qinhai Province of China previously.Field surveys and tests showed that the specie of insect pest occurred two generations each year in Anhui Province, and the main damage period was from March to May.The over-wintering adults came out from the soil in March and feed on rape flowers,buds and leaves,then oviposit on the leaves.After the eggs hatched,the larvae drilled into the leaves and fed on them until developing into mature larvae, which would fall into the soil to develop into pupas,then adults.Strongyllodes variegatus adults had over-summering and over-wintering habits.Strongyllodes variegatus prefered cool weather. The oilseed rape in mountain area suffered heavier damages by Strongyllodes variegatus than those in non-mountain area.Strongyllodes variegatus also damaged Chinese cabbage,cabbage and other cruciferous vegetables.The damage caused by Strongyllodes variegatus was becoming heavier and heavier in recent years.For the control of this pest,reducing the over-wintering pest sources with integrated pest control during flowering and budding period would be a suitable control strategy.The paddy-upland rotation was also effective in controlling this pest.
