| broadband photoreceptors are involved in violet light preference in the parasitoid fly exorista japonica. | phototaxis has been described in many insects, which are often attracted to specific wavelengths of light. however, little is known about phototaxis in parasitoid insect species that are potentially useful for integrated pest management. in this study, we investigated the wavelength dependency of the phototactic behavior of the parasitoid fly exorista japonica and its possible mechanism. multiple-choice tests with six monochromatic stimuli revealed that the flies were specifically attracted to v ... | 2016 | 27532635 |
| attraction to herbivore-induced plant volatiles by the host-foraging parasitoid fly exorista japonica. | responses of the tachinid fly exorista japonica townsend to odors from corn plants infested with the fly's host, the larvae of the noctuid moth mythimna separata (walker), were examined in a wind tunnel. naïve female flies showed a higher rate of landing on m. separata-infested corn plants from which the host larvae had been removed than on artificially damaged or intact corn plants. when paper impregnated with a solution of headspace volatiles collected from host-infested plants was attached to ... | 2008 | 18398656 |
| visual recognition of the host in the parasitoid fly exorista japonica. | we presented the tachinid fly exorista japonica with moving host models: a freeze-dried larva of the common armyworm mythimna separata, a black rubber tube, and a black rubber sheet, to examine the effects of size, curvature, and velocity on visual recognition of the host. the host models were moved around the fly on a metal arm driven by motor. the size of the larva, the velocity of movement, and the length and diameter of the rubber tube were varied. during the presentation of the host model, ... | 2005 | 15930829 |
| visual control of host pursuit in the parasitoid fly exorista japonica. | the tachinid fly exorista japonica is a parasitoid of many kinds of lepidopterous larvae. after encountering a suitable host, the fly pursues the crawling larva on foot using visual cues to guide it. to investigate the visual control of host pursuit, we observed and videotaped pursuits of a host, the common armyworm mythimna separata, for frame-by-frame analysis. observation was performed in sunlight and under illumination from a fluorescent lamp. the fly pursued hosts discontinuously with a rep ... | 2002 | 11893762 |
