摘要： 糠片蚧是湖南省柑桔上的主要害虫。据调查,糠片蚧的天敌中有寄生蜂6种,寄生率一般为5～10％。高的达34.75％。其中糠片蚧蚜小蜂为优势种,系首次发现。凡湿度大、肥力足的桔园寄生率较高,春梢上寄生率比秋梢和果实上的高,不喷农药的桔园比喷药的寄生率高出一倍以上。一年之中,寄生蜂发生高蜂期在秋季。

Abstract: During 1984-1887, surveys were conducted in 34 citrus orchards of Hunan Province for parasites of the chaff scale, ParJatoria perhandii, a major pest of citrus in the province. Six hymenopterous parasites were found, among which, Aphytis hispanicus was a new recording in the province and was found to be predominant. Parasitization rate of chaff scale was 5-10% in the fields, wrth a maximum of 34.7%. Relatively high parasitism was found in the orhcards with high humidity, fertile soil, and little insecticidal treatment. Parasitization of the scale on the spring shoots was found to be higher than that on the autumn-shoots and fruits. The population peaks of the parasites usuallyoccur in the autumn of a year.
