【摘要】 柑桔木虱是柑桔新梢期重要害虫,剌吸为害。福建福州在柑桔上一年发生8 代,在月桔、九里香上一年约发生 10 代左右,世代重叠,以成虫在柑桔叶背群集越冬,无完全滞育。4- 5 月气温 22.3℃世代历期 42.5天,6- 7 月 27.2℃为 24.4 天,8 月 28.1℃为 23.2 天,10- 12 月 19.6℃为 52.9 天。成虫寿命长,约历 1 个月半,越冬代长达半年。田间种群消长与柑桔芽梢抽发期相对应,一年中虫口数量出现 3 个高峰期,第一峰期 3- 4 月为柑桔春梢主要抽发期,第二峰期 5- 6 月为夏梢主要抽发期,第三峰期 8- 9 月为秋梢主要抽发期,其中以秋梢期虫口数量最大,秋芽受害最重,次为春梢期。本文还对柑桔木虱天敌进行调查,并对柑桔木虱卵、若虫和成虫进行药剂防治试验。

【Abstract】 The citrus psylla, Diaphorina citri Kuwayama (Homoptera, Psyllidae), is one of the important pests of citrus shoot stage. It develops, with generation overlapping, 8 generations on the citrus and 10 generations on the obovate kumquat and common jasminorange respectively per year in Fuzhou of Fujian Province, China. The pest overwinters with the adults crowding under the surface of leaves. The population dynamic of the citrus psylla appears 3 peak periods a year, closely related to the 3 stages of citrus shoot development, which are the spring shoot stage from March to April, the summer shoot stage from May to June and the autumn shoot stage from August to September. The population of the citrus psylla is the largest during the autumn shoot stage and results in the most damage, and secondly during the spring shoot stage. The duration of generation, biological characters, natural enemies and chemical control are also dealt with in the paper.
