本文应用灭蟑螂蚂蚁药毒饵,分别在实验室和远洋船舶对德国小蠊的杀灭作用进行了观察。结果表明,该药有良好的效果。在80×40×30cm的玻璃柜内,四组试验的LT_(50)为6.39～10.1天;轮船大面积投放毒饵后,5天平均杀灭率为71.6%,半个月为93.2%,1个月为95.4%,3个月为99.6%,近于绝迹。讨论了远洋船舶蟑螂的种类、传统喷洒法效果不佳的原因及投放毒饵的注意事项,提出了无论蟑螂密度高低均可大面积使用毒饵的观点。 In this paper, the ant poison bait of cockroach was applied to investigate the killing effect on German cockroach in laboratory and ocean-going ships respectively. The results show that the drug has good results. In the 80 × 40 × 30cm glass cabinet, the LT_ (50) of the four groups was 6.39 ~ 10.1 days after the bait was put on a large area. The average killing rate of the five days was 71.6% and 93.2% after 1 month 95.4% in a month, 99.6% in 3 months, almost extinct. The types of cockroaches in ocean-going vessels, the reasons for the poor effect of traditional spraying methods and the precautions of putting poison bait are discussed. A viewpoint is put forward that the bait can be widely used irrespective of the density of cockroaches.
