喷布油乳剂防治不同的柑桔害虫已应用了多年,但人们还未考虑到它适于防治柑桔锈壁虱(即柑桔锈螨:Phyllocoptruta oleivora)。Yothers等(1930)曾报导过他们在1912—1922年用油防治锈璧虱的试验,所用油剂浓度为0.5%,被处理的锈壁虱几乎全被杀死。有几项施用1%油剂防治锈壁虱的试验,采收时观察到果实上无锈色伤班。另有一些喷油试验,结果不大理想,作者们认定喷油只有部分效果,因为这种喷布是不完善的。 Sprayed oil emulsions have been used for many years against various pests of citrus, but no one has considered it suitable for controlling citrus rust mites (Phyllocoptruta oleivora). Yothers et al. (1930) reported that they used oil to control rust pest in the years 1912 to 1922 at a concentration of 0.5% and almost all of the rusty ticks were killed. There are several tests using 1% oil for the control of rust ticks, and no rusty wounds were observed on the harvest. In addition, some fuel injection tests, the result is not ideal, the authors believe that injection only part of the effect, because this spray is not perfect.
