国内从未报道过的一种地粉蚧——柑桔地粉蚧 Geococcus citrinus Kuwana 1960—1965 年在福建初次发现。它属于同翅目,蚧总科,粉蚧科。当年我们在资料交流时把它暂名为柑桔根粉蚧,果区群众称之为“小白虫”。这种国内柑桔上的新害虫在福建的一些果区严重发生为害,是引致柑桔树衰退的一个主要原因,群众迫切要求防治。根据生产上的需要,我们时柑桔地粉蚧的发生和为害情况进行过初步的考查,同时进行了药剂防治试验。本文除了介绍这两方面的工作结果外,并就分布、奇主和形态特征作简要的记述。
Geococcus citrinus Kuwana, a mealy scale ever reported in China, was first discovered in Fujian Province from 1960 to 1965. It belongs to the Homoptera, Scale Division, Fenyida Branch. In the same year, we tentatively referred to it as citrus root mealybugs in the exchange of information, and the fruit masses called it “little white worms.” The new pests on this domestic citrus tree are seriously harmed in some fruit areas in Fujian Province, which is one of the major causes of the decline of citrus trees. The people are pressing for prevention and treatment. According to the needs of production, when we citrus mealybug occurred and harm the initial examination, at the same time, the chemical control test. In addition to introducing the results of these two aspects of the work, this article provides a brief account of the distributions, unique forms and morphological features.
