Natural enemies of agricultural pests, such as parasitoids and predators, often use chemical and visual cues in search of their hosts and prey, and they can learn the association between the cues and the host and prey presence. The braconid, egg-larval endoparasitoid waspAscogaster reticulatais a promising biological control agent for tortricid pests, such asAdoxophyes honmai, in tea plantations. Although previous studies revealed thatA. reticulatauses contact chemicals released by tea plants in response to tortricid egg oviposition and that it can learn the associated cues, the diurnal wasp is also expected to use visual cues, especially color. Therefore, in this study, we investigated the innate color preference and associative color learning ability ofA. reticulata. When a green paper and a paper of a different color (black, blue, red or yellow) was offered together to naive females of the wasp, the females spent less time on a black and blue papers. However, wasps trained to associate black or blue with the presence of a host egg-mass showed increased preference for these colors, whereas red- and yellow-trained wasps did not show changes in preference. Our findings indicate thatA. reticulatauses colors, in addition to chemical cues, in host searching behavior and has the ability to learn colors associated with host presence.
