杨梅是浙江省的优势特色农产品,近年来以柏牡蛎蚧为主的介壳虫已成为杨梅主要害虫种类,且其发生为害呈明显上升趋势。通过在浙江台州黄岩、临海等杨梅主产区监测调查,探明了杨梅上常见发生为害的介壳虫有16种,隶属1目5科。其中,柏牡蛎蚧为优势种。柏牡蛎蚧在浙江1年发生2代,种群数量消长呈双峰型,5月下旬至6月上旬和8月上、中旬为主害期,为害杨梅春梢和夏梢。初步分析了寄主植物、栽培管理、田间防治、自然天敌、气候条件与害虫发生消长关系,制定了预测预报方法。药剂试验结果表明,植物源农药45%松脂酸钠可溶粉剂100倍液、150倍液喷雾防治,校正防治效果达97.99%、97.51%,对害虫防治效果好,使用安全,已在杨梅上登记,可应用于生产。研究提出了防控对策和农业防治、天敌保护利用与安全高效药剂防治相结合的综合防治技术,有效控制害虫的发生为害。
Yangmei is the predominant characteristic agricultural product in Zhejiang Province. In recent years, the scale insects that dominate the plantation have become the major insect pests of the genus Myrica rubra, and the incidence of the damage has been on the rise. Through monitoring surveys in the main producing areas of Yangmei, such as Huangyan and Linhai in Taizhou, Zhejiang Province, 16 species of common insects on the bayberry were identified as belonging to 1 order and 5 families. Among them, cypress oyster scale for the dominant species. Cypress oyster scale in Zhejiang 1 year occurred two generations, the population growth showed bimodal type, from late May to early June and August, the middle and the main period, damage bayberry spring shoots and summer shoots. Preliminary analysis of the host plant, cultivation and management, field control, natural enemies, climatic conditions and pest occurrence and decline of the relationship between the development of forecasting methods. The test results of the pesticide showed that the pesticide 45% sodium rosinate soluble powder of plant was controlled and sprayed with 100 times of liquid and 150 times of liquid. The control effect was 97.99% and 97.51% respectively. The pest control effect was good and safe to use. , Can be applied to production. The study put forward the integrated prevention and control and agricultural prevention and control, the protection and utilization of natural enemies and the safe and effective agent combination prevention and control technology to effectively control the occurrence of pests.
