茄瓜蓟马盆栽药效试验报告.doc

实验一、茄瓜蓟马盆栽药效试验报告1. 目的要求 利用盆栽实验比较几种不同农药对棕榈蓟马的防治效果，为田间实验提供依据。2. 实验材料2.1吡虫啉1500X 2.2哒螨灵2500X2.3阿维菌素1000X2.4苏云金杆菌1500X2.5啶虫脒1500X2.6高效氯氰菊酯 1500X2.7敌敌畏800X2.8乐斯本1500X3. 实验内容和方法全班分成5个小组，每个小组选六盆长势较一致的茄子，先检查每盆的茄子上的蓟马数量。应选取蓟马达30头以上的植株。每盆选取三片叶片记下每片叶的蓟马数量，挂上标签。最后用手压式小型喷雾器喷药。每个药剂三个重复，另外空白对照（仅喷清水）。然后施药后1d、3d、7d检查残存活的蓟马数。计算虫口减退率及校正虫口减退率。虫口减退率（%）=100%防治效果（%）=4结果整理及分析4.1 数据记录药剂喷药前虫口数喷药1d后虫口数喷药3d后虫口数喷药7d后虫口数吡虫啉1500X356260132285583102082450232221482哒螨灵2500X778372390134430450646262534460546232阿维菌素1000X3582918924320037421099457305553427苏云金杆菌1500X298247250242713411154242141935551啶虫脒1500X402387468386580442845519218206335315高效氯氰菊酯 1500X363353596453775692599383351328465246敌敌畏800X225154189359521211361400492306392232乐斯本1500X658401291768422304662561658401471320CK4285066286553313044144414934545342674.2杀虫剂对茄瓜蓟马处理后的虫口减退率及防效药剂喷药1d后喷药5d后喷药7d后虫口减退率防效虫口减退率防效虫口减退率防效吡虫啉1500X27.0%36.2%62.9%69.2%92.1%91.6%44.4%62.7%95.7%35.9%57.4%83.7%平均虫口减退率35.8%61.0%90.5%哒螨灵2500X52.2%20.5%49.9%-0.9%82.8%59.5%-4.7%-50.2%39.1%13.9%-2.2%56.6%平均虫口减退率20.5%-0.9%59.5%阿维菌素1000X18.7%-11.7%75.1%16.4%32.1%29.7%-87.0%-5.0%50.5%33.3%-21.0%6.6%平均虫口减退率-11.7%16.4%29.7%苏云金杆菌1500X17.1%-2.7%16.1%29.8%91.9%88.1%-25.8%57.6%84.5%0.5%15.7%87.9%平均虫口减退率-2.7%29.8%88.1%啶虫脒1500X3.7%11.0%-16.4%-38.6%4.0%-10.0%23.8%-45.7%10.5%5.5%-53.7%-44.5%平均虫口减退率11.0%-38.6%-10.0%高效氯氰菊酯 1500X2.8%6.7%-64.2%-24.7%-24.8%18.6%10.7%22.7%50.6%6.6%-32.5%29.9%平均虫口减退率6.7%-24.7%18.6%敌敌畏800X31.6%43.0%16.0%22.3%-59.6%5.5%59.5%30.7%23.2%37.8%20.3%52.8%平均虫口减退率43.0%22.3%5.5%乐斯本1500X39.1%35.4%55.8%9.1%-16.7%0.6%28.0%-56.9%-32.9%39.1%28.4%51.4%平均虫口减退率35.4%9.1%0.6%CK-18.2%-46.7%-53.0%8.2%-25.1%-33.2%7.9%-8.3%45.8%平均虫口减退率-0.7%-26.7%-13.5%4.3结果评估4.3.1用上述药剂及使用剂量防治棕榈蓟马，根据几天后的虫口减退率的统计分析可见，吡虫啉和苏云金杆菌的药效明显要高，而啶虫脒和乐斯本的药
