Abstract: | Flight activity in females of the parasitoid wasp Nasonia vitripennis(Walker) was examined by measuring still-air tethered flight. There was a large amount of variation among females in flight duration. The longest single flight (with no pauses of more than 5 s) was more than 2 h long. Mating status had a significant and large effect on flight: mated females flew twice as long as virgin females. There also was a slight but significant effect of age on flight, with 3-day-old females being less likely to fly than 1-day-old females. Flight duration was not affected by prior exposure to other females, to honey, or to a low or a high host density. |
