[Electroantennogram responses of the diamondback moth, Plutella xylostella, to three plant volatiles and field trapping test]
Acta Entomologica Sinica 48 (4), 503-508
Abstract: Electroantennogram (EAG) responses of the diamondback moth (DBM),Plutella xylostella to three plant volatiles, i.e. Z-3-hexen-1-ol (OH),Z-3-hexenyl cetate (ACTE) and allyl isothiocyanate (NCS), were tested in the laboratory. Tested with the volatiles at different concentrations of 0.008 µg/µL, 0.08 µg/µL, 0.2 µg/µL, 0.8 µg/µL, 8 µg/µL, 20 µg/µL and 40 µg/µL, DBM male or female had stronger responses to volatiles with higher concentration. Among the three volatiles, DBM had stronger response to NCS and ACTE. Responses to volatiles were different in male or female and in DBM mated or not. Field tests about aptures by the three volatiles with 6 µL per lure were conducted in Hubei province, China and in the suburb of Hanoi, Vietnam. DBM males were more attracted by ACTE and NCS at the two places at the beginning of the test, but the number of moths attracted by volatiles decreased quickly with time. Mixture of the three volatiles as 1:1:1 in volume also had good attractive activity to the diamondback moth. Few females were attracted by the three plant volatiles or their mixture.
