为寻找有效的杀灭蟑螂制剂，制备了复方灭蟑螂毒饵。采用实验室几种毒饵对比实验的方法，对制备的复方灭蟑螂毒饵进行了防制效果观察。适口性试验结果表明，德国小蠊对复方灭蟑螂毒饵２４ｈ消耗量为１２５ｍｇ，对混合饲料２４ｈ消耗量为６ｍｇ。敏感品系德国小蠊取食复方毒饵后，２４ｈ死亡率为５６．８％，４８ｈ死亡率为８２．３％，７２ｈ死亡率为１００％。对溴氰菊酯和氯菊酯有抗性的德国小蠊取食毒饵后，２４ｈ死亡率为５５．２％，４８ｈ死亡率为８１％，７２ｈ校正死亡率为９６．５％。该复方毒饵与溴氰菊酯和氯菊酯无交互抗性（０．０１＜Ｐ＜０．０５）。动物毒性试验结果表明，该毒饵对小白鼠的ＬＤ５０＞１００００ｍｇ·ｋｇ－１体重。在为期６周的现场试验中，投放毒饵后，德国小蠊若虫的密度下降率依次为：４３．０％、６１．６％、８９．２％、９６．２％９６．８％，成虫的密度下降率依次为７４．１％、７７．８％、９０．９％、９０．９％、９０．９％、９０．９％。复方灭蟑毒饵完全符合实际应用要求 In order to find an effective cockroach killing agent, a compound cockroach bait was prepared. The experiment of several baits in the laboratory was carried out to observe the preventive effect of the prepared compound cockroach bait. The palatability test results showed that the German cockroach 24h consumption of compound cockroach poison bait 24h, 125mg mixed feed 24h consumption of 6mg. Sensitive strain German cockroach feeding compound bait, 24h mortality was 56.8%, 48h mortality was 82.3%, 72h mortality was 100%. The baits were resistant to deltamethrin and permethrin after bait bait, 24h mortality was 55.2%, 48h mortality was 81%, 72h corrected mortality was 96.5%. The compound bait had no cross resistance with deltamethrin and permethrin (0.01

10000mg · kg-1 body weight. During the six-week field trial, the densities of nymphs of Germanic cockroach were decreased by 43.0%, 61.6%, 89.2%, 96.2% and 96.8%, respectively The density descending rates were 74.1%, 77.8%, 90.9%, 90.9%, 90.9% and 90.9%, respectively. Compound cockroach bait completely in line with the actual application requirements
