Abstract

Hung, C. C., Wang, W. L., Wu, C. Y., and Chang, C. H. 2016. Comparing the efficiency of different types

of traps for the diamondback moth,

Plutella xylostella

(Lepidoptera: Plutellidae ): an evaluation using field

data. Taiwan Pestic. Sci. 1: 91-106.

We compared the trapping efficiency of 5 commercial traps as well as various dry traps

and sticky traps that had been newly designed in this study. In all cases, traps were baited

with sex pheromones, and we compared their ability to capture diamondback moths (DBMs),

Plutella xylostella

, in cauliflower fields of Puyan and Tianwei, Changhua, Taiwan from 2003

to 2006. We found that none of the 5 commercial traps, including TDAR trap, Hwang’s

beauty fly trap, Fly Trap, Golden McPhail fly trap and Victor fly trap, were not suitable for

trapping DBMs when baited with sex pheromones. Conversely, of the many types of dry

traps we designed and tested, the 1-up-PET trap appears to efficiently capture DBMs when

the lure is placed in the lower section of the trap. In addition, the trapping efficiency of the

wing sticky trap was found to be better than that of the Cylinder sticky trap. For the wing

sticky trap, the location of the DBM lure (i.e., either on the bottom layer or on the cover layer

of the trap) had no influence on trapping efficiency; however, captured moths were mainly

found on the bottom layer. Finally, our data indicates that the PET water trap (i.e., a double

layer PET water trap with two entrances) may also be feasible for trapping DBMs.

Key words:

diamondback moth (

Plutella xylostella

), sex pheromone, dry trap, sticky trap,

water trap.
