摘　　要：中日合作研究了增效成分对桐酸酯类系列品种对玉米象的防治效果。试验表明含增效成分的桐酸酯对玉米象具有明显的致死效果,致死率为70%￣87.5%,未添加增效成分的处理致死率只有2.5%￣5%。不含增效成分的桐酸酯处理玉米象的平均产卵数是含增效成分处理的2.3倍,含增效成分的桐酸酯具有明显抑制害虫产卵的作用,对卵的羽化具有完全的抑制作用。A China-Japan cooperative research project was conducted to study the efficacy or an eleostearate series containing synergistic ingredients in controlling the maize weevil （Sitophilus zeamais）. Eleostearates containing synergists showed significant lethality toward the maize weevil, with mortalities between 70 and 87.5%. Mortalities without synergist were 2.5 to 5%. Average maize weevil oviposition rates in the absence of synergist were 2.3 times greater than treatments containing synergist. Eleostearates containing synergist significantly inhibited insect pest oviposition and completely inhibited larval emergence.
