[目的]研究广西金银花主要病虫及天敌昆虫的发生规律。[方法]于2008~2010年,在广西忻城县对各品种金银花上的主要病虫害、害虫主要捕食性天敌种群数量变化进行系统调查。[结果]胡萝卜微管蚜种群数量变化属单峰型,即在4月发生量较大;花蓟马和露尾甲的种群数量变化属双峰型,即在4月和9月发生量较大;白粉病的病情严重度的变化周期属双峰型,即在4月和9月的病情指数较高,而病梢率的变化周期属单峰型,即在4~6月的病梢率较高(毛花柱忍冬、红腺忍冬)和2~5月病梢率较高(华南忍冬),主要捕食性天敌双带盘瓢虫、七星瓢虫、异色瓢虫等种群数量变化属双峰型,即在4月和9月发生量较大。[结论]研究结果可为确定金银花主要病虫害防治适期、制定综合防治方案提供科学依据。
[Objective] The research aimed to study the rule of the main pests, diseases and insect pests of honeysuckle in Guangxi. [Method] From 2008 to 2010, the main pests and diseases of perennial honeysuckle and the population changes of major predatory natural enemies were systematically investigated in Xincheng County, Guangxi. [Result] The change of population size of carrot Aphis gossypii was monomodal, that is, the occurrence was large in April. The population change of flower thrips and Aralia elata was bimodal, that is, the occurrence in April and September was more Large; powdery mildew disease severity changes cycle is a bimodal type, that is, in April and September the disease index higher, and the change of disease rate of the peak period is a single peak, that is, in April and June of the disease The rate of population change was higher in populations with higher rates (honeysuckle honeysuckle, rhizomatous honeysuckle) and from May to May (honeysuckle wintersweet), major predatory natural enemies, such as ladybirds, ladybirds and ladybirds Bimodal, which occurred in April and September larger. [Conclusion] The results could provide a scientific basis for determining the suitable control period of main diseases and insect pests of honeysuckle and formulating the comprehensive prevention and cure plan.
