茶园杂草小飞蓬挥发物对茶小绿叶蝉行为的反应
Response of Tea Green Leafhoppers to Volatiles Emitted from Conyza canadensis Plants in Tea Plantations
摘要
Abstract
In the ecosystem of a tea plantation the effects of the volatiles released from the canopy of Conyza Canadensis plants on the behavior of tea green leafhoppers (Empoasca flavescence F.) were investigated.A Y-tube olfactometer was used to examine the response of the leafhoppers exposed to the volatiles emitted by the plants.It was found that the insects would significantly avoid the volatiles at the concentrations tested.A total of 47volatile compounds were isolated from the shoots and fresh leaves of the plants by SPME-GC-MS.Among them, D-limonene, (E) -β-farnesene, β-cubebene andβ-caryophyllene were most prominent.Ten synthetic chemicals representing them as well as some minor compounds in 3dosages, along with air as control, were subsequently exposed to the leafhoppers for the test using Y-tube olfactometer.It was observed that 10-3and 10 (-5) mL·mL-1β-pinene or 10 (-3) mL·mL-1β-caryophyllene significantly repelled the leafhoppers.Whereas, 10 (-3) mL·mL-1bisabolene significantly attracted the insects.关键词
