To assess the role of Aedes albopictus in transmission of filarial nematodes of veterinary importance, researches were carried out in different geographical areas. In Italy a first research was performed to study the susceptibility of Ae. albopictus to Dirofilaria repens, D. immitis and Setaria labiatopapillosa. The development of L3 larvae was longer than in other species of mosquitoes but Ae. albopictus could be a suitable vector of filariae. To understand the role of Ae. albopictus in the natural transmission of Dirofilaria and to assess the risk for animal and human health, in 2000, 2001 and 2002 another study was carried out in the town of Padua. A total of 2,534 Ae. albopictus were caught on human-attracted mosquitoes. Specific primers and sequencing identified filarial DNA as D. immitis; Ae. albopictus was proved a natural vector of D. immitis. Similar results were confirmed in Central Italy also for D. repens. The presence of Ae. albopictus increased the probability of transmission of canine and human dirofilariosis in urban environment and it could change the epidemiology of dirofilariosis, in particular for what concern the time of biting and the risk season. These aspects must be considered to outline a correct prophylaxis.
为评估白纹伊蚊在传播具有兽医重要性的丝虫线虫中的作用,在不同地理区域开展了研究。在意大利,首先进行了一项研究,以探究白纹伊蚊对匐行恶丝虫、犬恶丝虫和唇乳突丝状线虫的易感性。L3幼虫的发育时间比其他蚊种更长,但白纹伊蚊可能是丝虫的合适传播媒介。为了解白纹伊蚊在恶丝虫自然传播中的作用,并评估对动物和人类健康的风险,2000年、2001年和2002年在帕多瓦镇开展了另一项研究。在诱捕到的嗜人按蚊中,共捕获了2534只白纹伊蚊。特异性引物和测序鉴定出丝虫DNA为犬恶丝虫;已证实白纹伊蚊是犬恶丝虫的自然传播媒介。在意大利中部,对于匐行恶丝虫也证实了类似结果。白纹伊蚊的存在增加了城市环境中犬类和人类恶丝虫病传播的可能性,并且可能改变恶丝虫病的流行病学,特别是在叮咬时间和风险季节方面。在制定正确的预防措施时,必须考虑这些方面。
