Estimation of some characteristic dispersal ranges of diamondback moth (Plutella xylostella) (Lepidoptera: Plutellidae)
نویسندگان
چکیده
The dispersal ranges of the diamondback moth (Plutella xylostella) were estimated with mark-recapture collected during 1998-2000 in commercial cauliflower and broccoli crops in the northern Adelaide plains. Moths were marked with fluorescent powder and released at one or more points within the experimental fields. Recaptures of the marked moths were made with pheromone traps and yellow sticky buckets (YSB), the latter were used to trap both sexes of the moth. Four indices of dispersal ranges were estimated, the average dispersal distances and the distances within which 95, 99 and 99.9% of the released moths were expected to remain. The average dispersal distances estimated from the recapture data with pheromone traps were 21-35 m and those from the YSB recapture data were 14-18 m for the males and 13-24 m for the females. The 95, 99 and 99.9% distances estimated from YSB recapture data were 41-54 m, 69-90 m and 117-164 m respectively for the males and 40-72 m, 63-120 m and 113 –203 m respectively for the females. The corresponding distances estimated from the recapture data with pheromone traps were 62-106 m, 104177 m and 176-300 m respectively. Implications of the results in the designing and implementation of insecticide resistance management strategies and in a number of alternative control strategies are discussed.

The diamondback moth, Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae), is a major pest of cruciferous vegetables worldwide. Cantharidin, a natural toxin isolated from blister beetles, has been reported to be toxic to P. xylostella. However, little is known on the chronic sublethal effects of cantharidin on this species. In this study, we assessed the changes of susceptibility, develop...
