小麦皮蓟马是福海县春麦生产上主要害虫之一。据查,全县所有麦田均有不同程度的发生,一般每株虫口密度为29头左右,多则达96头。经82—83年调查资料表明:每年因该虫的危害,全县约损失小麦100万斤左右。为探讨化学农药防治此虫的较有效途径,1984年进行了六种新农药的防效实验。 共试药剂为2.5％敌杀死乳油(即溴氢菊酯。法国、罗索、优克福公司)。20％速灭杀丁乳油(即杀灭菊酯。日本,住友化学工业株式合社产)。40％久效磷乳油〈江苏省、南通农药厂产)。36％优杀磷乳油〈山 Wheat thrips is one of the major pests on spring wheat production in Fuhai County. According to the investigation, all the wheat fields in the county have different degrees of occurrence. Generally, the density of each insect population is about 29 and the number reaches 96. After 82-83 years of investigation data show that: the annual damage due to the insects, the county about the loss of about 1000000 pounds of wheat. In order to explore the chemical pesticides to control this pest more effective way, in 1984 carried out six kinds of new pesticide control experiment. A total of 2.5% of the co-test agents kill the EC (ie Brommethrin, France, Roseau, Optik). 20% speed kill kill EC (ie fenvalerate Japan, Sumitomo Chemical Co., Ltd.). 40% monocrotophos
