Psocids have become global pests of stored commodities as they can cause considerable economic losses. These insects are difficult to control because they have developed resistance to many chemical insecticides. Therefore, it is crucial to investigate alternative integrated pest management (IPM) approaches, such as the use of light attraction for monitoring and/or controlling psocids. Light attraction has been studied for Liposcelis bostrychophila Badonnel (Psocoptera: Liposcelididae) but not for other psocid species. In this study, we investigated the response of adults of three psocid species (Psocoptera: Liposcelididae), Liposcelis entomophila (Enderlein), Liposcelis paeta Pearman, and Liposcelis brunnea Motschulsky, to six wavelengths of light from light-emitting diode (LED) in paired-choice pitfall tests. L. entomophila females and males were not attracted to any of the wavelengths tested. L. paeta females responded positively to two ultraviolet (UV) wavelengths (351 and 400 nm) and to green light (527 nm), while males did not respond to any light. L. brunnea females and males responded positively to all six wavelengths evaluated. Most of the LEDs that elicited positive responses to L. paeta females and L. brunnea females and males were also preferred when these lights were presented against brewer's yeast, a food attractant highly preferred by several psocid species. Females of L. paeta and L. brunnea were attracted to white light when compared with a blank, but females of L. entomophila were not attracted to white light compared to a blank.
书虱已成为全球储存商品的害虫，因为它们会造成相当大的经济损失。这些昆虫很难控制，因为它们已对许多化学杀虫剂产生了抗性。因此，研究替代的综合虫害管理（IPM）方法至关重要，例如利用光诱捕来监测和/或控制书虱。已经对嗜卷书虱（Liposcelis bostrychophila Badonnel，啮目：书虱科）进行了光诱捕研究，但尚未对其他书虱种类进行研究。在本研究中，我们在配对选择陷阱试验中研究了三种书虱（啮目：书虱科），即嗜虫书虱（Liposcelis entomophila，恩德勒林）、小眼书虱（Liposcelis paeta，皮尔曼）和褐皮书虱（Liposcelis brunnea，莫施尔斯基）的成虫对发光二极管（LED）发出的六种波长光的反应。嗜虫书虱的雌性和雄性对所测试的任何波长光均无反应。小眼书虱的雌性对两种紫外（UV）波长（351和400纳米）以及绿光（527纳米）有正向反应，而雄性对任何光均无反应。褐皮书虱的雌性和雄性对所有六种评估波长光均有正向反应。当将这些光与啤酒酵母（几种书虱种类高度偏好的食物引诱剂）对照呈现时，大多数对小眼书虱雌性和褐皮书虱雌性及雄性产生正向反应所需的LED也更受青睐。与空白对照相比，小眼书虱和褐皮书虱的雌性被白光吸引，但嗜虫书虱的雌性与空白对照相比对白光无反应。
