The main pest species and their occurrence regularity in the guava orchards imported into Fujian from Taiwan

通过普查、系统调查和诱集法对入闽台湾番石榴园的害虫种类及主要害虫的发生规律进行研究。结果发现番石榴害虫(螨)74种,隶属8目46科。主要害虫包括桔小实蝇Bactrocera dorsalis(Hendel)、棉蚜Aphisgossypii Glover、小绿叶蝉Empoasca flavescens(Fabricius)、黑刺粉虱Aleurocanthus spiniferus Quaintance、花蓟马Frankliniella intonsa(Trybon)、桉小卷蛾Strepsicrates coriariae Oku等。桔小实蝇为害高峰期在8-9月;棉蚜在夏秋季和秋末冬初发生较严重;蓟马类的发生与番石榴的花期密切相关,其高峰期在6月份。

Based on systematical investigation and sex attractant,the pest species and their occurrence regularity in the guava orchards imported into Fujian from Taiwan were studied.The results showed that there were 74 guava pests,belonging to 7 orders and 46 families.in which Bactrocera dorsalis,Aphis gossypii,Empoasca flavescens,Aleurocanthus spiniferus,Frankliniella intonsa and Strepsicrates coriariae were the main pests.The peak of B.dorsalis was from August to September.Aphis gossypii occurred more seriously in summer,autumn and early winter,while thrips reached peak in June and there was close relationship between the occurrence of thrips and the bloom season of guava.
