Abstract: | Studies were carried out in the laboratory on the influences of time of day, temperature, relative humidity and starvation
on flight initiation byProstephanus truncatus (Horn) (Coleoptera: Bostrichidae). Flight occurred throughout the 12 h photophase and at the beginning of the scotophase
but peaked at 2–0 h before darkness. Temperature exerted a significant effect on flight. The frequency of flight take-off
increased with temperature over the range 20–30°C but declined sharply at 35°C. Flight activity increased with starvation
up to a maximum at 2 days after which it began to decline. |
