摘要: Apolygus lucorum (Meyer-Dur) (Hemiptera: Miridae) is a serious pest of cotton, jujube, grape and many other crops around the world. Understanding how olfactory information directs this insect to its host plants may provide environment-friendly approaches control population in agriculture. In our study, we cloned an odorant receptor gene, AlucOR46, that was specifically expressed antennae female-biased. Functional expression AlucOR46 Xenopus oocytes showed it tuned six plant volatiles (S)-(−)-Limonene, (R)-(+)-Limonene, (E)-2-Hexenal, (E)-3-Hexenol, 1-Heptanol (1R)-(−)-Myrtenol. Electroantennogram (EAG) recordings revealed all compounds could elicit electrophysiological responses from A. lucorum, higher females. Our results are agreement with previous reports showing (E)-2-Hexenal attract female behavior experiments. These suggest might play important role locating therefore represents suitable target for green control.
