目前蓟马已成为危害大棚辣椒和传播辣椒病毒病的重要害虫.近年农户采用各种杀虫剂进行防治,虽有一定的防效,但也为农产品质量安全埋下潜在风险.近年来,各生产厂家相继推出多种替代农药防治害虫的产品,其中粘虫纸防治蓟马在国内有相关报道.为了明确粘虫纸对大棚辣椒上蓟马的防治效果,及比较不同生产厂家粘虫纸粘虫水平,为实际生产应用提供依据,设计本试验.
福奇150ZC（微囊悬浮-悬浮剂）是先正达公司开发的新一代高效、广谱性杀虫混剂，其有效成分为氯虫苯甲酰胺和高效氯氟氰菊酯，互补了两个单剂的防治范围，同时其不同的作用机理也延缓了害虫抗性的产生。作者于2010年进行了福奇150ZC防治西兰花菜青虫田间药效试验，为生产防治提供技术依据[3-5]。
白粉病是玫瑰的主要病害之一，生产上防治长期以三唑类农药为主，由于大量使用农药，白粉病对药剂的抗性上升较快。75%肟菌·戊唑醇（拿敌稳）水分散粒剂由新的甲氧基丙烯酸酯类杀菌剂肟菌酯和内吸性三唑类杀菌剂戊唑醇复配而成，杀菌活性较高、内吸性较强，既具有保护作用又具有治疗作用。作者于2009年进行了75%肟菌·戊唑醇（拿敌稳）WG防治大棚玫瑰白粉病田间药效试验，为生产上防治玫瑰白病提供替代药剂[1-3]。
The population dynamics of Spodoptera exigua by using the sex-pheromone from 2001-2003 in Kunming of China was monitored.The result indicated that it happened in each month.The number of adult begin increase from the last ten-day of March and decrease from the last ten-day of October,the main period of the month appeared from April to June.In winters,the number of adult was low.In the greenhouse vegetable crops the peaks of population happened from May to June.The number of adult happened in June on the land.It's happened on the flower every month,and the peaks of population happened from June to September in the greenhouse.According to the population dynamics,the author analyses the reason about its outbreak not only its population proliferate dynamics but also suitable temperature,cultivation practices,allocation of crops and prevention plant pests.
