The African parasitoids Cephalonomia stephanoderis Waterston (Bethylidae: Hymenoptera), Prorops nasuta Betrem (Bethylidae: Hymenoptera), and Phymastichus coffea LaSalle (Eulophidae: Hymenoptera) are biological control agents of the coffee berry borer (Coleoptera: Curculionidae). In this study, we investigated in laboratory the female behavioral responses of these parasitoids to 14 different wavelengths (340-670 nm) against a control (570 nm, yellow). When nonchooser females were included in the analysis, none parasitoids species showed a preference between 340, 350, 370, 460, 490, 520, 540, 590, 640, and 650 nm with respect to the control wavelength. In contrast, the three species of parasitoids were more attracted to wavelengths of 380, 400, and 420 nm than the control wavelength. Phymastichus coffea and P. nasuta were more attracted to the wavelength of 400 and 420 nm compared to C. stephanoderis. At 380 nm, P. coffea and C. stephanoderis wasps showed the higher responses in comparison to P. nasuta females. When nonchooser wasps were excluded from the analysis, we observed other differences among the parasitoid species. For instance, P. coffea were more attracted to 490-540 nm than to 570 nm, whereas the bethylids did not discriminate between 490-540 nm or 570 nm. Our results are discussed in relation to possible implications associated with the vision of these parasitoid species.

为控制咖啡浆果Bor（Curculionidae：Scolytinae），向美洲进口的三种寄生虫的颜色偏爱。

非洲寄生虫头足纲头孢菌属（Bethidae：Hymenoptera），Prorops nasuta Betrem（Bethylidae：Hymenoptera）和Phymastichus coffea LaSalle（Eulophidae：Hymenoptera）是咖啡bore的生物防治剂（Coleoptera：Curculionidae）。在这项研究中，我们在实验室研究了这些寄生虫对14种不同波长（340-670 nm）相对于对照（570 nm，黄色）的女性行为反应。当将非选择雌性动物包括在分析中时，相对于对照波长，没有任何寄生虫种类在340、350、370、460、490、520、540、590、640和650 nm之间显示出偏好。相反，与对照波长相比，这三种寄生虫对380、400和420 nm波长的吸引力更大。Phymastichus咖啡和P. 与Stephannoderis相比，nasuta对400和420 nm的波长更有吸引力。在380 nm处，相比于nasuta雌性，P。coffea和C. stephanoderis黄蜂表现出更高的响应。当将非选择性黄蜂从分析中排除时，我们观察到了寄生蜂物种之间的其他差异。例如，P。coffea在490-540 nm处比在570 nm处更易吸引，而甲壳虫在490-540 nm或570 nm之间没有区别。我们讨论了与这些寄生虫物种的视觉可能产生的影响有关的结果。我们观察到了寄生虫物种之间的其他差异。例如，P。coffea在490-540 nm处比在570 nm处更易吸引，而甲壳虫在490-540 nm或570 nm之间没有区别。我们讨论了与这些寄生虫物种的视觉可能产生的影响有关的结果。我们观察到了寄生虫物种之间的其他差异。例如，P。coffea在490-540 nm处比在570 nm处更易吸引，而甲壳虫在490-540 nm或570 nm之间没有区别。我们讨论了与这些寄生虫物种的视觉可能产生的影响有关的结果。
