市区约有三大类场所65个点,阳性点69.2%,共调查719点次,阳性率为48.5%;幼虫度密平均43.1条/勺;发现蚊种3属16种,以淡色库蚊为优势种,其次为凶小库蚊;幼虫四月份出现,七月份达到高峰,十二月下旬消失,幼虫密度变化和气候变化相一致,蚊幼主要孳生在倾倒生活垃圾和有机物多的孳生场所。翻缸倒水,定期换水并彻底清除底层有机物,特殊场所用药物处理能达到有效防制蚊幼虫的目的,加盖处理对蚊幼孳生无明显影响。
There were 65 points in three main types of places in the urban area, with a positive point of 69.2%. A total of 719 points were surveyed and the positive rate was 48.5%. The density of larvae averaged 43.1 pieces per square meter. Three mosquito species, 16 genera, The dominant species was secondly, Culex pipiens pallens larvae. The larvae appeared in April and peaked in July. The larvae disappeared in late December. The larval density change was consistent with the climate change. The mosquito larva breed mainly in dumping household garbage and many organic breeding places. Turn over the water tank, regularly change the water and completely remove the underlying organic matter, special places with drug treatment can achieve the purpose of effective anti-mosquito larvae, stamped with mosquito breeding no significant impact.
