Estimation of the Dispersal Distance of the Onion Thrips, Thrips tabaci Using Traps
JAPANESE JOURNAL OF APPLIED ENTOMOLOGY AND ZOOLOGY(2015)
摘要
We investigated the dispersal distance of the onion thrips, Thrips tabaci Lindeman, using traps. In a greenhouse, fourteen hours after releasing thrips, we found insects at sticky traps up to 54m from the release point. The estimated mean dispersal distance (+/- SE) was 7.4 +/- 0.25m at thirty-nine hours after releasing thrips. In a field, forty-eight hours after releasing thrips applied with the fluorescent brightening agent, we found insects at traps up to 119m from the release point. The estimated mean dispersal distance (+/- SE) was 66.6 +/- 10.7m.
