Botanical pesticides are playing an increasingly important
role in the control of agricultural pests. In this study, the
insecticidal effects of the essential oil extracted from Chinese
chive (EOC) against Plutella xylostella larvae were confirmed in
terms of their repellent action and contact toxicity. The repellent
actions of four pyrazines isolated from EOC were studied based
on electroantennograms (EAG). The effects on glutathione
S-transferase, carboxylesterase and acetyl cholinesterase were
assayed after treatment with EOC. EOC had an obvious effect on
the EAG and inhibited the activities of glutathione S-transferase
and carboxylesterase in treated P. xylostella larvae, which could
explain their repellent action and contact toxicity. In addition, two
principal sulfide compounds in EOC, diallyl disulfide and methyl
disulfide, were tested. Both showed the repellent action and
contact toxicity against P. xylostella larvae, although weaker than
the effects of EOC. The four pyrazines isolated from essential oil of
Chinese chive showed better repellent activities than that of EOC.
