Abstract：
[Objectives] To investigate the effects of hunger and thirst on the
activity of adult B. minax. [Methods] The ratio of active
to inactive insects, and the height climbed by individual insects on day 1 and
day 10 of the experiment, were measured and compared in a group of insects
deprived of food and water and a control group provided with food and water. [Results] The ratio of
active to inactive insects was significantly higher in the deprived group than
in the control group.
Females in the deprived group climbed
significantly higher on day 1, and the ratio of active to inactive
insects, and height climbed per insect, were higher than control females on day
10. There was no significant difference in the ratio of active to inactive
insects and the height climbed per insect between males and females. [Conclusion] Starvation
and thirst can increase the activity and potential dispersal range of adult B. minax.
