摘要
于2018年调查了湖南省江永县柑橘园的柑橘木虱种群发生动态,并在防虫网室内观察了柑橘木虱的生活史和习性。结果表明:椪柑园和夏橙园的柑橘木虱种群数量较高,香柚园的则相对较低;果园抽梢期柑橘木虱发生严重程度,椪柑园表现为夏梢>秋梢>春梢,夏橙园表现为秋梢>春梢>夏梢,香柚园则主要在春梢和秋梢期发生;失管或管理不当果园的柑橘木虱种群数量远大于正常管理的果园;若持续有寄主新梢,柑橘木虱在湖南地区一年可完成10个世代,卵—若虫的历期通常为15~26 d,在甜橙和九里香上的发育历期无显著差异。综合柑橘木虱的生物学特性和柑橘的栽培特点,一年中有2个防治柑橘木虱的重要时间点,分别在冬季和夏季。
The field population dynamics of Diaphorina citri Kuwayama(Hemiptera:Liviidae)was investigated in Jiangyong county,Hunan province in 2018.The life history and behavior habits of D.citri were observed in artificial net-room.The results showed that in ponkan and summer orange orchards the population density of D.citri was high,while in sweet pomelo orchard it was relatively low.The order of occurrence severity of D.citri at shoot phase was summer shoot period>autumn shoot period>spring shoot period in ponkan orchard,autumn shoot period>spring shoot period>summer shoot period in summer orange orchard.D.citri occurred mainly in spring shoot and autumn shoot periods in sweet pomelo orchard.The population density of D.citri in neglected orchards was much higher than that of orchards under normal management.If there are persistent host shoots,D.citri can complete 10 generations of development in a year in Hunan.The total developmental duration from eggs to nymphs is 15 to 26 days,which has no significant difference between sweet orange and Murraya exotica L..According to biological habits of D.citri and cultivation characteristics of citrus,winter and summer are two important time points to control D.citri during the year.
