Abstract
Abstract Information on insect phototaxis can be applied to the collection, monitoring, and management of insects. This study investigated the phototaxis of three species of Cryptolestes (Coleoptera: Laemophloeidae)—Cryptolestes pusillus (Oliver), Cryptolestes turccus (Grouvelle), and Cryptolestes ferrugineus (Stephens)—to light-emitting diode (LED) lights with six wavelengths. The three species had different responses to the different wavelengths, with C. pusillus displaying the strongest phototaxis. The taxis of the three species exhibited the same tendency across light waves of different lengths. All showed positive taxis to 450-, 390-, and 530-nm wavelengths, and their highest taxis indices occurred with 450 nm. The taxis indices of all three Cryptolestes species were positively correlated to light intensity.
