摘要:

柑桔木虱没有得到有效控制是正常管理柑桔园黄龙病发生严重的最重要原因,弄清这些果园柑桔木虱种群的年发生规律是有效防治柑桔木虱和柑桔黄龙病的基础。6年的系统调查结果表明,10-12月份是木虱种群数量最多的时期,其次分别是9月、1月和5月。9-12月的柑桔木虱数量与次年的柑桔黄龙病发生率呈显著正相关。

Abstract:

The main reason for the outbreak of Citrus Huanglongbing is that the Diaphorina citric Kuwayama hasn’t been well controlled. Figuring out the annual regularity of outbreak for Diaphorina citri Kuwayama is the basis to effectively control Diaphorina citri Kuwayama and Citrus Huanglongbing. According to a six-year systemic investigation, we found that October to December is the peak time for population of Diaphorina citric Kuwayama, and followed by September, January and May respectively. The Huanglongbing’s incidence rate of next year is markedly positive correlated with the Diaphorina citri Kuwayama quantity of September to December.
