Movement of Monochamus alternatustiope (Coleoptera: Cerambycidae) Adults among Young Black Pine Trees in a Screen Cage

摘要

Movement of adult Monochamus alternatus was investigated on young black pine, Pinus thunbergii, trees for about one month in a screen cage. Number of pine trees to which M. alternatus females and males moved during the experimental period was 6.4±1.4and 7.2±1.5 out of 15 trees, respectively. Adult females and males moved to 0.2±0.1 and 0.3±0.1 tree per day, respectively. A 74.6 and 80.7% of adult females and males moved at night (17:00-08:00) to other trees. After moving, most beedes (72.6% of females and 76.0% of males) stayed on the tree to which they moved for one to two days. Some beetles stayed for up to seven days.
