以石油为基础的专有园艺油阳光喷雾6E Plus对温室菊花(Dendranhema×gran-diflorum(Ramat.)北村冰山)。2%(v/v)水喷雾剂喷洒后对成虫驱避时间至少为11d，对初孵化和三龄幼虫均有毒杀作用。每周喷洒1%、2%和4%的油剂均未观察到植物毒性。
The repellency and toxicity of a petroleum-based proprietary horticultural oil, Sunspray 6E Plus, was tested against the greenhouse whitefly, Trialeurodes vapor- ariorum (Westwood), on greenhouse-gr own chrysanthemums (Dendranthema ×gran- diflorum (Ramat.) Kitamura cv. Iceberg). A 2% (v/v) aqueous spray repelled adult whiteflies for at least 11 days after spraying and it was toxic to newly hatched and third stage larval whiteflies. No phytotoxicity was observed when four weekly sprays of 1%, 2%, and 4% oil were applied.
