摘　　要：目的测定不同食物对德国小蠊的引诱效果,筛选出一种诱杀效果较好的毒饵,为德国小蠊的化学防治提供更有效的指导。方法采用四臂嗅觉仪从多种食物材料中筛选出对德国小蠊引诱作用较好的食物,将其与杀虫剂配成毒饵。结果4组食物中诱集效果最好的分别为炒大豆粉、小白菜汁、香蕉和葡萄糖,诱集率分别达到63.33%、59.44%、63.33%和42.78%,将引诱效果较好的4种食物进行最佳引诱试验,发现炒大豆粉对德国小蠊的引诱效果最好,诱集率达到45.66%;香蕉次之,诱集率为25.83%,与溴氰菊酯或辛硫磷混配后,香蕉毒饵的诱杀效果较好。结论通过筛选发现炒大豆粉和香蕉对德国小蠊有很强的引诱性,利用香蕉所配制的毒饵诱杀效果最好。Objective To determine the attractiveness of different foods and identify an effective attractant that can act as a toxic bait for chemical control for Blattella germanica. Methods The four-arm olfactometer was used to sort out strongly attractive foods from a variety of edible materials for B. germanica. The candidate was then prepared with insecticides into toxic baits. Results The strongest attractants identified from four groups were fried soybean powder,cabbage juice,bananas and glucose,with attracting rates of 63.33%,59.44%,63.33% and 42.78%,respectively. The four best attractive ingredients were subject to the optimal luring test,which showed that fried soybean powder had the greatest attracting effect on B. germanica with the attracting rate of 45.66%,followed by bananas （25.83%）. Combined with deltamethrin or Phoxim,bananas could act as the most efficiently attractive toxic bait. Conclusion The screening study showed that soybean powder and bananas had strong attractiveness for B. germanica. Bananas can be used to produce the most effective toxic bait.
