Psocids are difficult to manage using grain protectants and phosphine hence research on non-chemical control methods. This study evaluated the effectiveness of (Reuter) (Hemiptera: Anthocoridae) at managing (Pearman) (Psocodea: Liposcelididae). The functional responses of adult♀ and nymphs of on a diet of nymphs, adult♂, and adult♀ of were determined under laboratory conditions at 28 ± 1 °C, 63 ± 5% RH, and a 0:24 (L:D) photoperiod. Maximum likelihood estimates (MLEs) of a logistic regression analysis showed that the functional responses of the life stages of on diets of three stages of were Holling Type II. Estimates of the attack rate (), handling time (), maximum predation () per day, and predation efficiency () per day for the two predator life stages against each prey life stage showed that the adult♀ predation rate was better compared with the nymphs. The adult♀ per capita consumption rate and searching efficiency were also higher than those of the nymphs. The data showed adults of are more favorable for adult♀ whereas their nymphs prefer nymphs of . Field evaluation of is required for their incorporation into psocid pest management.
啮目昆虫很难使用谷物保护剂和磷化氢进行防治，因此需要开展非化学防治方法的研究。本研究评估了小花蝽（Reuter）（半翅目：花蝽科）对嗜卷书虱（Pearman）（啮目：书虱科）的防治效果。在28 ± 1 °C、相对湿度63 ± 5%、光周期0:24（光照:黑暗）的实验室条件下，测定了小花蝽成虫♀和若虫以嗜卷书虱若虫、成虫♂和成虫♀为食时的功能反应。逻辑回归分析的最大似然估计（MLEs）表明，小花蝽各虫态对嗜卷书虱三个虫态的功能反应均为Holling II型。两种捕食者虫态对各猎物虫态的攻击率（a）、处理时间（Th）、每日最大捕食量（1/Th）和每日捕食效率（a/Th）估计表明，小花蝽成虫♀的捕食率优于若虫。小花蝽成虫♀的人均消耗率和搜寻效率也高于若虫。数据表明，小花蝽成虫更偏好嗜卷书虱成虫♀，而其若虫更喜欢嗜卷书虱若虫。需要对小花蝽进行田间评估，以便将其纳入书虱害虫管理。
