系统介绍了书虱（booklice）实验种群的饲养技术。研究表明虱啮属（Lopscelis）昆虫的最佳饲养条件为：饲料；全麦粉+酵母粉+脱脂奶粉（10:1:1）；温度25～28℃，相对湿度75%-80%。以嗜卷书虱Loposcelis bostrychophila和嗜虫书虱Lopasocilis entoruphila这例，分析了上述饲养条件对两种书虱的生长发育及繁殖力影响的结果。

用植物性杀旦剂苦皮藤素Ⅳ（KTP乳症）有效成份30.15mg/kg防治柑橘潜叶蛾，采用离体叶片受叶法处理5b 3d后，幼虫校正虫口减退率分别为89.63%，63.02%；枝梢浸寝泡处理5s，5d后，潜道伸长度校正抑制率分别为76.12%和41.51%；10d后，对树梢的相对保叶效果分别为69.34%和52.29%。结果表明，采用KPT乳油有效成分30mg/kg对柑橘潜叶蛾有较好的控制作用，对柑橘秋哺有良好的保护效果。

测试结果表明：苦皮藤乳油对莱粉蝶的卵没有直接杀伤作用，但卵孵化出的幼虫却有较高的死亡率，对1-5龄不同龄期的莱青虫进行胃毒测试，苦皮藤素LC50分别为24.7mg/kg，72.55mg/kg，124.35mg/kg，1240.42 mg/kg，田间药效试验表明，一次施药50mg/kg和100mg/kg的苦皮藤乳油对菜青虫的防效差异不显著，但保产效果明显不同。研究蛄果表明，苦皮藤乳油防治菜青虫的有效浓度以50mg/kg为宜。

The effects of controlled atmosphere (CA) and DDVP on population growth and resistance development by the psocid, Liposcelis bostrychophila Badonnel, were studied in the laboratory. Results indicated that the population of L. bostrychophila increased rapidly under natural conditions; after 11 weeks, this population had increased 48.1-fold at 288C, 80% relative humidity (r. h.). Exposure to CA (35% CO2, 1% O2) or DDVP (Dichlorvos, 0.3 mg/ml) alone failed to control the population growth. After 11 weeks, populations increased 4.3-and 9.1-fold, respectively. However, alternating exposure to CA and DDVP provided a significant increase in mortality as compared to those exposed to CA or DDVP alone. The results of bioassay showed that both populations exposed to CA and DDVP developed a low but significant resistance to CA and DDVP, respectively. After six exposures, the level of resistance to CA and DDVP increased 1.8-and 2.0-fold, respectively. Probit analysis did not show an appreciable increase in slope value of either population in spite of continuous exposures, indicating considerable heterogeneity of these psocids in response to CA or DDVP and suggesting a greater potential for the development of higher levels of resistance. It is suggested that alternating CA with insecticides could be an important management measure for psocids in storage. #2002 Elsevier Science Ltd. All rights reserved.

Six plant essential oils alone as repellent and fumigant, and in combination with the controlled atmosphere against Liposcelis bostrychophila Badonnel were assessed in the laboratory. These essential oils were extracted from the leaves of six source plants: Citrus tangerina Tanaka, Citrus aurantium L., Citrus bergamia Risso et Poiteau, Pinus sylvestris L., Cupressus funebris Endl., and Eucalyptus citriodora Hook. The repellency test indicated that L. bostrychophila adults were repelled by

采用饲料混毒法系统测定了吡丙醚和烯虫酯两种昆虫生长调节剂（IGRs）对重要的储藏物害虫嗜卷书虱Liposcelis bostrychophila Badonnel若虫和成虫的致死作用，对若虫发育情况、成虫繁殖力和卵孵化率的影响。结果表明，以吡丙醚和烯虫酯10mg/kg的混毒饲料饲喂嗜卷书虱2龄幼虫49d后，若虫的死亡率分别为80.00%和31.11%；取食20、10和5mg/kg吡丙醚的若虫最长存活天数分别为71.0、98，2和116.4d，而对照仅11.3d即全部羽化为成虫；取20mg/kg以下烯虫酯混毒饲料的若虫一部分仍可羽化成成虫，而且成虫仍可繁殖后代；取食吡丙醚混毒饲料的若虫，60d后存活下来的若虫大多以超龄若虫的形式存在，而取食烯虫酯的若虫则很少出现超龄若虫。成虫取食烯虫（200mg/kg）和吡丙醚（40mg/kg）混毒饲料后7d，死亡率分别为26.67%和23.33%，成虫产卵量分别是对照的39.77%和26.13%，产卵后15d，卵的孵化率分别是65.71%和8.69%，而对照仅为93.18%。该项研究表明，采用40mg/kg吡丙醚和200mg/kg的烯虫酯对嗜卷书虱虫口数量有明显的控制作用。

Book 1ouse Liposcelis bostrychophila is a minor pest in stored products, and may seriously infest the stored prod, ucts when its population outbreaks. This study was conducted to evaluate the toxic effect of DDVP on various development stages ofL, bostrychophiha. The results showedthat at 28±0.5℃ and 24h exposure under 75%～80% RH, the LCso of the eggs, 18-rvae of 1st to 4th stadium, and adults was 16.83, 0.22, 0.22, 0.23, 0.26 and 0.25ug·L-1, respectively. The 1ethal effect of DDVP on the adults at different exposure periods showed that their mortality was linearly related to the treated time. implying that the test colony of L. bostrychophila was susceptible to DDVP. In the practical fumigation. DDVP as a fumigant had a good effect on the pest control if the development stage, time and periods of treatment were appropriate.

近年来书虱逐渐成为储藏物环境中的优势害虫种群，严重危害储粮的品质。已引起粮食储运、植物检疫和卫生部门的高度重视。本文介绍了书虱的主要类群及生物学特性，指出其大量发生的危害性，系统讨论了在储粮环境中书虱猖獗发生的因子，指出书虱的生殖潜力及高温和高湿等是有利于书虱种群发展的生态因子，而在储粮过程中采用的不恰当的熏蒸和气调处理措施则是导致书虱暴发的主要原因。
