摘要
采用定点观察和普查的方式对湖南省吉首市、麻阳县柑橘大实蝇的危害特点进行了研究。结果表明:柑橘大实蝇对不同柑橘品种的危害时间由早到晚依次为:脐橙>温洲蜜柑>冰糖橙≥大红甜橙=广柑>椪柑;其危害最严重的品种是脐橙,虫果率达63%,其次是早熟温洲蜜柑和冰糖橙,达22%,再次是椪柑,达6%;同时还发现,柑橘不同品种果皮表面存在产卵假痕迹现象。这些结果可为柑橘大实蝇的防治提供理论参考依据。
The damage characteristics of Tetradacus citri Chert in Mayang County, Jishou City, Hunan Province were investigated by fixed-point observation method and general survey method. The results indicated that the harm time of Tetradacus citri Chen on different varieties of citrus ordered as navel orange〉satsuma mandarin〉Citrus sinensis ≥Citrus sineasis Osbeck cv. Dahong= Citrussinensis （L.） Osbeck〉Citrus reticulata Blanco cv. Ponkan; the damage level of Tetradacus cirri Chen on different varieties of citrus ordered as navel orange〉early mature satsuma mandarin and Citrus sinensis 〉Citrus reticulata Blanco cv. Ponkan, and the insect infestation ratio of navel orange, early mature satsuma mandarin, Citrus sinensis and Citrus reticulata Blanco cv. Ponkan was 63%, 22%, 22% and 6%, respectively. Meanwhile, the research also showed that there are fake oviposition traces of Tetradacus citri Chen on the Peels of different varieties of citrus. These results above can provide the theory basis for the control of Tetradacus citri Chen.
