Abstract:

Olfactory responses of Plutella xylostella to polyamines were measured using a Y-tube olfactometer in the laboratory. The results indicated that the diamondback moth adults both unmated and mated had an obvious orientation response to the three polyamines tested (spermine, spermidine, and putrescine) compared with distilled water; but no significant difference in their choice between these three polyamines. Except that unmated males had an obvious orientation response to putrescine compared with cabbage juice and mated male had an obvious orientation response to cabbage juice compared with spermine, the moths had the same orientation response to the three polyamines and cabbage juice.


Key words: Plutella xylostella, polyamines, spermine, spermidine, putrescine, olfactory response
