Miracidia of the eyefluke Philophthalmus megalurus were tested in phi-chambers to determine if they reacted similarly to chemicals found stimulative for miracidia of Philophthalmus gralli, a closely related species. Philophthalmus megalurus miracidia were less responsive than P. gralli to the dicarboxylic amino acids and showed a significantly positive response only to 10 mM glutamic acid. These P. megalurus miracidia were chemonegative to 10 mM HCl and H2SO4, chemicals to which P. gralli miracidia gave a significantly positive response. Ammonia and Mg2+ did not elicit any response from P. megalurus miracidia.
对大眼嗜眼吸虫的毛蚴在φ小室中进行测试，以确定它们对与亲缘关系相近的格氏嗜眼吸虫毛蚴有刺激作用的化学物质是否有类似反应。大眼嗜眼吸虫毛蚴对二羧酸氨基酸的反应不如格氏嗜眼吸虫毛蚴灵敏，仅对10 mM谷氨酸有显著的阳性反应。这些大眼嗜眼吸虫毛蚴对10 mM盐酸和硫酸呈化学阴性反应，而格氏嗜眼吸虫毛蚴对这些化学物质有显著的阳性反应。氨和镁离子未引起大眼嗜眼吸虫毛蚴的任何反应。
