摘要
目的了解粤北地区的医学媒介生物本底情况。方法采用光催化诱捕器捕蚊,捕蝇笼诱捕法捕蝇,粘蟑盒诱捕法捕蜚蠊。结果蚊类有1亚科2属3种,以致倦库蚊为优势种群,季节消长从4月份开始升高,后呈双峰型,冬季密度较低。蝇类有3科4属6种,以家蝇和市蝇为优势种群,2004年季节消长在6月份有一个高峰,2005年全年密度大幅下降。蜚蠊有2科2属4种,以德国小蠊为优势种群,季节消长以冬季密度较低,后随气温升高而升高,2005年密度比2004年有所上升。结论从2004与2005年的对比可见,韶关市区除四害工作还有待进一步加强,须采取以环境治理为主的综合防治措施,防止媒介传播疾病的发生和扩散。
Objective To study the diversity and distribution of medically important insect vectors in the northern area of Guangdong. Method Photochemical catalysis traps,fly catchers,and cockroach catchers were used in this study. Result There is only one subfamily, two genera, and three species of mosquito. Culex pipiens fatigans is the dominant species. The activity of this species increased from April and reached a bimedal peak. The population density is low in winter. There are three families, four genera, and six species of fly. Domestica and sorbens are the dominant species. The fly population reached a peak density in June 2004, and the density descended sharply in 2005. Cockroach comprises of two families, two genera and four species. Blattella germanica is the dominant species. The population density of cockroach was affected by the temperature. The density is low in winter. The density of cockroach in 2004 is lower than 2005. Conclusion By comparing the changes of insect vectors between 2005 and 2004, we can conclude that the pest control measure should be tighten in the urban areas of Shaoguan.
