经３ａ试验观察，查清了愈纹萤叶甲的生活史：愈纹萤叶甲以卵越冬，１ａ１代；成虫在羽化后取食近２０ｄ，高温时在葱地及附近背阴处钻入土壤表层枯叶下呈半休眠状态越夏近９０ｄ。对葱的为害期为幼虫、成虫羽化初期、成虫越夏后至产卵前３阶段。防治应在为害最集中的幼虫期和成虫产卵前。 After 3a observation, the life history of A. lucorum was found out: A. unguiculatus eggs overwintered for generations 1aa; adults fed on eclosion for nearly 20 days, and drilled into the soil at the shade and nearby shade at high temperature The surface of the dead leaves showed a semi-dormant summer nearly 90d. Onion damage on the larvae, early adult emergence, adult summer after the summer before spawning 3 stages. Prevention should be in the most concentrated larvae and adult eggs before spawning.
