摘要
测试3种季酮酸类药剂对脐橙上柑桔红蜘蛛的室内毒力和田间药效。结果表明:柑桔红蜘蛛对螺螨酯、螺甲螨酯和螺虫乙酯三种药剂对的敏感性远低于阿维菌素,以田间喷施不同药剂2 d后以阿维菌素的防效最高,螺虫乙酯为最低且差异显著。7 d后螺螨酯、螺甲螨酯和阿维菌素的防效无显著差异,但这三种药的防效仍然显著高于螺虫乙酯。而到14 d后,四种药剂的防效相当,无显著差异。
The toxicity and field control efficacy of three tetranic acid to citrus red mite Panonychus citri were stud- ied. The results showed that citrus red mite is more susceptible to abamectin than spirodiclofen, spiromesifen and spi- rotetramat. The efficacy of abamectin is highest and spirotetramat is lowest after two days of spray. There is no signifi- cant difference to the field efficacy of spirodiclofen, spiromesifen and abamectin after seven days of spray, but the field efficacy of the above three is still higher than that of spirotetramat respectively. The field efficacy of four pesti- cide have no significant difference after fourteen days of spray.
