实验室条件下研究了涕灭威、甲氨基阿维菌素苯甲酸盐和丙溴磷在低剂量胁迫下对甘薯茎线虫趋化性的影响. 结果表明:在无药剂胁迫情况下甘薯茎线虫对灰霉菌、半裸镰刀菌的趋化性最强,其次为马铃薯,对甘薯无趋性. 在含有5~510~(-2)μg/mL涕灭威、甲氨基阿维菌素苯甲酸盐和丙溴磷的水琼脂平板,线虫的趋化性均受到抑制,且甲氨基阿维菌素苯甲酸盐的抑制活性高于其他2种药剂;线虫经10~(-1)~10~(-3)μg/mL的涕灭威、甲氨基阿维菌素苯甲酸盐和丙溴磷浸溃24 h后采用灭菌去离子水清洗3次并恢复24 h后,线虫的趋性仍受到抑制. 值得注意的是,在含5×10~(-3)μg/mL丙溴磷水琼脂或经丙溴磷10~(-3)~10~(-4)μg/mL...

The effects of different type of nematicides on the chemoreceptive activity of Ditylenchus destructor were tested by using a chemoreception bioassay in vitro. Nematodes were placed in the centre of a petri dish containing 1% agar base. The attractants, including Botrytis cinerea, Fusarium semitectum, potato cutting and sweet potato cutting, were placed at equal distance from the centre. The 1% water agar discs were used as blank. The results showed that B. cinerea and F. semitectum were significantly much more attractive than potato cutting, an...
