摘要/Abstract

摘要： 东亚小花蝽Orius sauteri (Poppius)作为一种重要的捕食性天敌，被广泛用于多种温室害虫的防控。由于该天敌具有在植物组织内产卵的特殊习性，其卵的发育离不开植物，导致筛选适宜的产卵基质植物一直是其规模繁育的重要基础。豆科植物不仅可以作为绿肥和保护型生物防治的功能植物，而且还可以作为东亚小花蝽的适宜产卵基质。因此，本研究以产卵量、产卵持续时间、卵孵化时间、卵孵化率及净生殖力等为指标，在实验室内评价了豇豆、菜豆、大豆、豌豆、绿豆和花生6种豆科植物作为东亚小花蝽产卵基质的适合度。结果表明：东亚小花蝽在绿豆上的总产卵量和净生殖力最高，分别为72.0粒和59.5头，显著高于菜豆、大豆和花生；卵孵化率最高的是花生，为86.79%，但与绿豆并无显著差异；东亚小花蝽在6种植物上的产卵持续时间无显著差异，在绿豆上卵的孵化时间最短，显著低于菜豆和花生。东亚小花蝽在绿豆上的产卵位置也优于其他植物，所以综合考虑绿豆为所试6种植物中东亚小花蝽的最适产卵基质植物。

Abstract: Orius sauteri (Poppius), an important predatory natural enemy, is widely used in the management of various greenhouse pests. The predator lays eggs into plant tissues and relies on plants for egg development, which entails the screening of suitable oviposition substrate plants (OSP) for mass rearing. Leguminous plants are green manure plants and functional plants in conservation biological control, and are potential suitable OSP for O. sauteri. The study evaluated the fitness of cowpea, kidney bean, soybean, pea, mung bean and peanut as OSP for O. sauteri in the laboratory. The results showed that the total egg numbers and net fecundity of O. sauteri were 72.0 and 59.5, respectively, when mung bean was used as OSP, which were significantly higher than those of the insects when kidney bean, soybean or peanut was used as OSP. The highest egg hatching rate (86.79%) was observed with peanut, which was not significantly different from that with mung bean. There was no significant difference in the oviposition duration of the predators on the six plants, whereas the egg hatching duration on mung bean was the shortest, significantly shorter than those on kidney bean and peanut. Taken together, mung bean is the most suitable OSP for O. sauteri among the six tested plants.
