半蛞蝓Parmarion cf. 1893年，在夏威夷的奥廷加首次发现了martensi Simroth，然后在2004年在夏威夷岛发现。该物种可能原产于东南亚，在夏威夷岛东部大量存在，据报道在某些地区取代了古巴蛞蝓Veronicella cubensis（Pfeiffer，1840）。2005年7月至8月的一项调查发现，P. cf. martensi主要分布在夏威夷岛的下普纳地区，在Kailua-Kona（夏威夷岛西部）有一个孤立的种群。它现在在商业木瓜种植园中建立，调查参与者报告说它是家庭花园中莴苣和木瓜的害虫。调查受访者认为P. cf.此外，由于它喜欢爬上排泄物所在的建筑物，而且有传播疾病的潜力，因此，它也是一种有害生物。发现该物种的个体携带大量感染性广州管圆线虫第三期幼虫（Chen，1935），广州管圆线虫是人类管圆线虫病的病原体，也是人类嗜酸性脑膜脑炎的最常见原因。利用新开发的聚合酶链反应测试，77.5%的P.cf。在调查点采集的100只马氏链霉菌中发现有A.广州卷叶螟（V. cubensis）为24.3%，而同一地区的古巴卷叶螟（V. cubensis）为24.3%。该物种的传播潜力可能高于夏威夷的其他蛞蝓和蜗牛，因为感染率高，蠕虫负担，以及它与人类居住地的更大联系，增加了人类与软体动物相互作用的可能性。
ABSTRACT The semi-slug Parmarion cf. martensi Simroth, 1893, was first discovered on O‘ahu, Hawai‘i, in 1996 and then on the island of Hawai‘i in 2004. This species, which is probably native to Southeast Asia, is abundant in eastern Hawai‘i Island, reportedly displacing the Cuban slug, Veronicella cubensis (Pfeiffer, 1840), in some areas. A survey in July–August 2005 found P. cf. martensi primarily in the lower Puna area of Hawai‘i Island, with an isolated population in Kailua-Kona (western Hawai‘i Island). It is now established in commercial papaya plantations, and survey participants reported it as a pest of lettuce and papaya in home gardens. Survey respondents considered P. cf. martensi a pest also because of its tendency to climb on structures where it deposits its feces and because of its potential to transmit disease. Individuals of this species were found to carry large numbers of infective third-stage larvae of the nematode Angiostrongylus cantonensis (Chen, 1935), the causative agent of human angio-strongyliasis and the most common cause of human eosinophilic meningo-encephalitis. Using a newly developed polymerase chain reaction test, 77.5% of P. cf. martensi collected at survey sites were found infected with A. cantonensis, compared with 24.3% of V. cubensis sampled from the same areas. The transmission potential of this species may be higher than that for other slugs and snails in Hawai‘i because of the high prevalence of infection, worm burdens, and its greater association with human habitations, increasing the possibility of human-mollusk interactions.
