目的了解东莞市病媒生物鼠、蚊、蝇、蜚蠊、伊蚊的本底和种群季节消长,为制定防制对策提供依据。方法2006年在城区及郊区选点,分别用笼夜法、诱蚊灯法、诱蝇笼法、粘捕盒法、诱蚊诱卵器法监测鼠、蚊、蝇、蜚蠊、伊蚊密度。结果鼠类以小家鼠为优势种,占43.10%;蚊类以致倦库蚊为优势种,占99.70%;蝇类以家蝇为优势种,占64.29%;蜚蠊以德国小蠊为优势种,占97.64%。年平均密度分别为6.01%、27.4只/灯、0.87只/笼、1.29只/盒。鼠、蚊、蜚蠊全年有活动,出现两个明显的活动高峰,分别在5月、8月;5月、12月和7月、11月。蝇的活动受环境因素影响较大,密度季节消长不明显,波动较大。伊蚊全部为白纹伊蚊,年平均密度为2.33%,活动高峰在7月和10月。结论掌握本市病媒鼠、蚊、蝇、蜚蠊、伊蚊的本底情况,应在病媒密度高峰前采取有针对性的防制措施,降低病媒密度。
Objective To understand the background and seasonal fluctuation of vector-borne gerbils, mosquitoes, flies, cockroaches and Aedes mosquitoes in Dongguan City, and to provide evidence for the development of control strategies. Methods In 2006, the density of mice, mosquitoes, flies, cockroaches and Aedes mosquitoes were monitored in the urban and suburban areas by using the method of cage night, trap lamp, fly trap, . Results The dominant species was Mus musculus, accounting for 43.10% of the total. Musca domestica was the dominant species, accounting for 99.70%. Musca domestica was the dominant species, accounting for 64.29% of the total. Blattella germanica was the dominant species Species, accounting for 97.64%. The annual average density was 6.01%, 27.4 / lamp, 0.87 / cage, 1.29 / box. Rats, mosquitoes and cockroaches are active throughout the year, with two distinct activity peaks occurring in May and August; May, December and July and November respectively. The activities of flies are greatly influenced by environmental factors, the density of the season is not obvious, fluctuate greatly. Aedes albopictus are all Aedes albopictus, the annual average density of 2.33%, the peak activity in July and October. Conclusion To master the background of disease vector mice, mosquitoes, flies, cockroaches and Aedes mosquitoes in the city, we should take targeted control measures before the peak of vector density to reduce the vector density.
