According to the LC-P line of each of insecticide in the mixture and the formula of co-toxicity factor, several expected mortality and the region of additive action (expected mortality±20% expected mortality) were calculated, and according to observed mortality of mixture, the 95% confidence interval was calculated, LC-P line of expected mortality with the region of additive action and LC-P line of observed mortality with the 95% confidence interval were drawn, it was found that there was overlap between the region of additive action and 95% confidence interval and two lines crossed each other when co-toxicity coefficient was more than 100 and the co-toxicity factor was less than 20, which meant there was no significant differences between expected mortality and observed mortality, and that there was on or a few overlap between the region of additive action and 95% confidence interval when co-toxicity coefficient was more than 100 and the co-toxicity factor was more than 20 or co-toxicity coefficient was less than 100 and the co-toxicity factor was less than 20, which meant there was significant differences between expected mortality and observed mortality.

根据单剂的LC-P线和共毒因子公式，求出混剂的期望死亡率和"相加作用区间"（期望死亡率±20%期望死亡率），根据混剂的实测死亡率求出95%置信区间，画出期望LC-P线及"相加作用区间"和实测LC-P线及"95%置信区间"，发现当共毒系数大于100、共毒因子小于20时，实测LC-P线和期望LC-P线彼此交缠，期望LC-P线的"相加作用区间"和实测LC-P线的"95%置信区间"能高度重叠，表明两条LC-P线之间没有毒力差异；当共毒系数大于100、共毒因子大于20，或者共毒系数小于100、共毒因子小于-20时，实测LC-P线的"95%置信区间"和期望LC-P线的"相加作用区间"只有少量重叠或完全不重叠，体现出了实测LC-P线和期望LC-P线对供试害虫的毒力差异。

结果表明，在中华绒螯蟹的饲料中添加每千克蟹体重400.0mg至1200.0mg的免疫多糖，对中华绒螯蟹的生长速度和身体颜色等没有显著影响；能有效地增强供试中华绒螯蟹的抗病力，与对照组相比，经口服攻毒后投喂不同剂量免疫多糖试验组的中华绒螯蟹有效率为52.4%~66.77%，而经注射攻毒后各试验组中华绒螯蟹的有效率为39.2%~49.9%，口服攻毒后的有效率稍高可能与病原体的感染方式有关。

Toxicity and repellent activity of several plant-based compounds on Blattella germanica were studied, results showed that rotenone, toosendanin and azadirachtin had stomach toxic effect on Blattella germanica, rotenone showed high stomach toxicity and all insects died after 8 hours, matrine also has deformative effect on Blattella germanica , matrine and toosendanin can affect oviposition of Blattella germanica; repellent activity of these botanicals was further studied, results showed that bering hydrochloridum, azadirachtin and sparteinehave had repellent activity against Blattella germanica, observation also showed that rotenone and bering hydrochloridum had high contact toxicity against Blattella germanica, the time of all insects knocked down were 8 and 48 hours.

选取了7种植物源化合物，测定了它们对德国小蠊的毒性和驱避性，结果表明，鱼藤酮、川楝素和印楝素对德国小蠊具有不同程度的胃毒作用，其中鱼藤酮乙酸乙酯溶液作用较强，8小时死亡率已达100％，川楝素和印楝素对德国小蠊也表现出一定的毒杀作用，观察还发现印楝素和苦参碱对德国小蠊的发育有致畸作用，苦参碱和川楝素影响其卵鞘形成；进一步对这几种化合物的驱避性进行研究，结果表明盐酸黄连素、鱼藤酮乳油和印楝素乳油对德国小蠊有不同程度的驱避作用，其驱避率分别为96.7％、51.3％和50.1％，另外观察到鱼藤酮乙酸乙酯溶液和盐酸黄连素对德国小蠊具有较强的触杀活性，供试虫全部被击倒的时间分别为8小时和48小时。
