| 摘 要： | 为探明贵州威宁地区马铃薯田间蚜虫种类及消长动态,为蚜虫的防治提供科学依据,对4-7月田间黄皿诱蚜进行数量调查和种类鉴定.结果表明:威宁地区马铃薯田间有翅蚜共12种,其中桃蚜、玉米蚜、甘蓝蚜为主要种群.有翅蚜的消长动态受气象因素影响较大,其中以温度和湿度影响较大,风速次之.4月中旬和5月中旬为有翅蚜发生的两个高峰期,6月中旬有翅蚜大量迁飞,建议该地区的蚜虫防治至少应包括这3个时段.

| Abstract: | The quantity and types of aphids in potato fields from April to July were determined and identified to verify its types and growth and decline trends,and provide a scientific basis for aphid control.The results showed that there were 12 types of alatea,in which Myzus persicae,Rhopalosiphum maidis and Brevicorvne brassicae were dominant populations,and its growth and decline trend was obviously affected by temperature and humidity,followed by wind speed.There were two occurrence peaks in the middle ten days ... |
