Mass production is a prerequisite for using natural enemies in integrated pest management and organic farming. Natural enemies in agroecosystems include predators that prey on insects, which they can subdue while maintaining adequate pest population densities. The Leafhopper Assassin Bug (LAB), , can be a natural enemy in agroecosystems, selecting its prey for size and mobility. Some of LAB's prey include (L.), (Rossi), (Matsumura), and Kuwayama, suggesting this reduviid for biocontrol agent in various contexts. We reared LABs for two subsequent broods offering living prey and artificial diets. Our data show that the rearing of is feasible with oligidic, meridic, and holidic artificial formulations. Four artificial diets allowed the complete post-embryonic development of LABs in captivity for two successive generations. The accumulated degree-days (ADDs) accurately predict the growth of LABs based on heat accumulation, estimating that up to three generations could grow per year in captivity at the experimented T°C.
大规模生产是在综合虫害管理和有机农业中使用天敌的前提条件。农业生态系统中的天敌包括捕食昆虫的捕食者，它们能够在维持足够害虫种群密度的同时制服害虫。叶蝉猎蝽（LAB）可以成为农业生态系统中的一种天敌，它会根据猎物的大小和活动能力来选择猎物。LAB的一些猎物包括黑尾叶蝉（Nephotettix cincticeps (Uhler)）、大青叶蝉（Cicadella viridis (L.)）、电光叶蝉（Inazuma dorsalis (Motschulsky)）和桑斑叶蝉（Erythroneura mori (Kuwayama)），这表明这种猎蝽在各种情况下都可作为生物防治剂。我们用活体猎物和人工饲料连续饲养了两代LAB。我们的数据表明，使用低质、半纯和全纯人工配方饲养LAB是可行的。四种人工饲料使LAB在圈养条件下连续两代完成胚胎后发育。积温（ADDs）基于热量积累准确预测了LAB的生长，估计在实验温度T°C下，圈养条件下每年最多可生长三代。
