Psocids are damaging stored-product pests. In this study, eggs and early-instar nymphs, adults, and all life stages of Liposcelis entomophila, L. decolor, L. bostrychophila, and L. paeta were subjected to 43, 50, or 75% (Control) relative humidity (RH) for 2, 4, 6, 8, 10, 12, 14, or 16 d at 30.0°C. All adults of these species died within 8 d at both 43 and 50% RH, except for L. bostrychophila, which required 12 d at 50% RH for 100% mortality to occur. For all life stages and eggs and early-instar nymphs, maximum survival times (times to 100% mortality) at 43 or 50% RH for L. entomophila, L. decolor, L. bostrychophila, and L. paeta, were 8 and 10 d, 8 and 12 d, 12 and 14 d, and 12 and 16 d, respectively. During this study, numbers of nymphs and adults of all species 14 d after the RH treatments increased within the 75% RH Control arenas. Different species and life stages responded differently to 43 and 50% RH, as time to kill all stages of the four psocid species was 8-12 and 10-16 d, respectively. Results indicate that using a specific RH environment may be effective in psocid management.

除湿对四种伴生物种生存的影响。

人民正在破坏储存的产品有害生物。在这项研究中，对卵和嗜脂脂虫，脱色乳杆菌，乳突孢杆菌和paeta乳杆菌的卵和早熟若虫，成虫以及所有生命阶段进行了43％，50％或75％（对照）的相对湿度（RH）的测定。 ）在30.0°C下放置2、4、6、8、10、12、14或16天。这些物种的所有成年动物在43％和50％相对湿度下均在8 d内死亡，除了嗜麦芽孢杆菌（L. bostrychophila）需要在50％RH下12 d才能发生100％的死亡率。对于所有生命阶段，卵和早熟若虫，在43或50％相对湿度下，嗜L. enophophila，L。decolor，L。bostrychophila和L. paeta的最大存活时间（达到100％死亡率的时间）分别为8和10。分别为d，8和12 d，12和14 d以及12和16 d。在这项研究中，RH处理后14 d内所有物种的若虫和成虫数量在75％RH对照区域内增加。不同的物种和生命阶段对43％和50％RH的反应不同，因为杀死这四个梭菌物种所有阶段的时间分别为8-12 d和10-16 d。结果表明，使用特定的RH环境在人为管理中可能是有效的。
