叶足虫Leptoglossus zonatus(Dallas)(Het.，Coreidae)在尼加拉瓜饲养，只吃未成熟的坚果(麻疯树，大戟科)果实。这种寄主植物的适宜性用从卵到成虫的发育阶段的死亡率和不同阶段的持续时间来描述，这些死亡被列在生命表中。给出了产卵前时间、产卵量和每头雌虫的总产卵量。对所有的幼虫进行了生物测量。对新鲜药用坚果的蛋白质、脂肪和水分含量进行了全年测定。结果表明，坚果是一种高度适宜的寄主植物，果实不断，营养品质波动不大，全年可维持该害虫的种群。
The leaf‐footed bug Leptoglossus zonatus (Dallas) (Het., Coreidae) was reared in Nicaragua on a diet consisting of unripe physic nut (Jatropha curcas L., Euphorbiaceae) fruit only. The suitability of this host plant is described by the mortalities in the developmental stages from egg to adult, which are presented in a life table, and the durations of the different stages. Pre‐oviposition time, number of ovipositions and total number of eggs per female are given. Biometric measurements of all instars were made. Protein, oil and water content of fresh physic nut fruit were measured throughout a whole year. The results show that physic nut is a highly suitable host plant, which can maintain populations of this insect pest throughout the whole year as fruit are constantly present with only little fluctuation in their nutritional quality.
