The insectoacaricid Briz 25% e.c. was tested for its effects on Toxocara canis eggs in pure culture. In the solar-illuminated laboratory at 22-23°C, T. canis eggs of pure culture were destroyed on days 17-18 when in 1.25% aqueous emulsion of the insectoacaricid Briz 25% e.c. (0.313% with reference to the active ingredient cypermethrin). Within the egg, the parasite failed to die not only in the stage of protoblast (5-6 days), but also in the stages of semiformed (4 days) and mobile larva (7-8 days), i.e. for 16-17 days of the experiment. After eggshell destruction, T. canis larvae actively entered the working aqueous emulsion of Briz 25% e.c. and died within the first hours in the test agent. The working aqueous emulsion of Briz 25% e.c. (1.25% with reference to the agent or 0.313% to the active ingredient cypermethrin) exerted ovicidal and larvicidal activities against the pathogen of T. canis in the pure culture on days 17-18 at 22-23°C.
对25%乳油制剂Briz杀螨杀虫剂进行了纯培养条件下对犬弓首蛔虫卵作用的测试。在温度为22 - 23°C的阳光照射实验室中，当处于25%乳油制剂Briz的1.25%水乳剂（按活性成分氯氰菊酯计为0.313%）中时，纯培养的犬弓首蛔虫卵在第17 - 18天被破坏。在虫卵内，寄生虫不仅在原胚阶段（5 - 6天）没有死亡，在半成形阶段（4天）和活动幼虫阶段（7 - 8天）也未死亡，即在实验的16 - 17天内都未死亡。卵壳被破坏后，犬弓首蛔虫幼虫积极进入25%乳油制剂Briz的工作水乳剂中，并在测试剂中最初几个小时内死亡。25%乳油制剂Briz的工作水乳剂（按制剂计为1.25%或按活性成分氯氰菊酯计为0.313%）在22 - 23°C下于第17 - 18天对纯培养的犬弓首蛔虫病原体具有杀卵和杀幼虫活性。
