In laboratory experiments an introduced fish Perccottus glenii consumed selectively tadpoles of three numerous anuran amphibian species of Moscow Province. Perccottus glenii actively consumed all seized tadpoles of the Rana arvalis and R. temporaria. These predators consumed significantly lesser number of Bufo bufo tadpoles and frequently rejected them after seizing without considerable damages. Observations showed that P. glenii rejects B. bufo after intraoral testing. Larvae of dragonfly Aeschna cyanea also actively consumed almost all seized R. arvalis tadpoles, while usually rejected B. bufo after attacking and damaging them. Larvae of diving beetle Dytiscus marginalis sucking out captured prey, intensively consumed tadpoles of R. arvalis and B. bufo and did not reject them.
在实验室实验中，引入的葛氏鲈塘鳢选择性地捕食了莫斯科省三种数量众多的无尾两栖动物的蝌蚪。葛氏鲈塘鳢积极捕食所有捕获的泽蛙和林蛙蝌蚪。这些捕食者捕食的中华大蟾蜍蝌蚪数量明显较少，并且在捕获后经常将其拒食，而中华大蟾蜍蝌蚪并未受到严重损伤。观察表明，葛氏鲈塘鳢在口内测试后会拒食中华大蟾蜍蝌蚪。蓝纹大蜓幼虫也积极捕食几乎所有捕获的泽蛙蝌蚪，而在攻击并损伤中华大蟾蜍蝌蚪后通常会将其拒食。龙虱幼虫通过吸食捕获的猎物，大量捕食泽蛙和中华大蟾蜍蝌蚪，并且不会将其拒食。
