The minute pirate bug Orius insidiosus (Say) is an important predator in mango agroecosystems. It attacks several species of thrips, particularly Frankliniella invasor Sakimura, which is considered a species of economic importance in mango. We investigated the effect of six diets on the development, survival, and reproduction of O. insidiosus: 1) first instars of F. invasor, 2) second instars, 3) adults, 4) pollen, 5) pollen plus thrips larvae, and 6) water. Individuals fed on thrips larvae, with or without pollen, completed their immature development significantly faster. Nymphs of O. insidiosus were able to complete their development feeding on pollen only, while individuals that received water as a diet were unable to reach the adult stage. The highest intrinsic growth rate was obtained when O. insidiosus were fed on pollen plus thrips larvae, and the lowest when individuals were fed on thrips adults. Our studies show that a diet of pollen plus F. invasor larvae is optimal for O. insidiosus development and population growth.

在富兰克林入侵者（缨翅目：蓟马科）上饲养的 Orius insidiosus（半翅目：Anthocoridae）的发育、生存和繁殖

微小的海盗虫 Orius insidiosus (Say) 是芒果农业生态系统中的重要捕食者。它攻击几种蓟马，特别是富兰克林氏菌入侵者 Sakimura，这被认为是芒果中具有经济重要性的物种。我们研究了六种饮食对 O. insidiosus 的发育、存活和繁殖的影响：1) F. invasor 的一龄期，2) 二龄期，3) 成虫，4) 花粉，5) 花粉加蓟马幼虫，以及6) 水。以蓟马幼虫为食的个体，无论有无花粉，都明显更快地完成了它们的未成熟发育。O. insidiosus 的若虫能够仅以花粉为食完成发育，而以水为食的个体无法达到成虫阶段。当 O. insidiosus 以花粉和蓟马幼虫为食时，获得了最高的内在生长速率，当个体以蓟马成虫喂养时最低。我们的研究表明，花粉加 F. invasor 幼虫的饮食对于 O. insidiosus 的发育和种群增长是最佳的。
