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。

RESULTS: On day 2 after PH, oval cells began to proliferate around the portal area, and matrilin-2 deposition was observed in the hepatic sinusoids in the periportal area. On day 9, proliferating oval cells were present in the hepatic acini, and matrilin-2 upregulation was noted. On day 12, as oval cells differentiated to form hepatocellular nodules, matrilin-2 was distributed mainly in the periphery of the nodules, and little protein was present in the nodules.
