WANG Pi-yu; ZHOU Hong-ning; GU Yun-an;et al
Objective To investigate malaria vector biology behavior,distribution and seasonal fluctuation,and to make out reasonable vector control measures. Methods At the peaks of malaria transmission from May to October,collected mosquito two times every month by human biting catches and houses catches methods. Results By houses catches,in cattle pens,a total of 11 414 individuals of 25
Anophelesspecies were collected,
An.sinensisis the predominant species (63.72%),its peaks of population density occurred in May and June,i.e.49.25 and 56.56 individuals per hour per pen respectively,but in October,its density declined to 15.50 individuals per hour per pen; for
An.minimus,its proportion was 4.87% of total collected mosquitoes,its peak of density was from August to October. In human house,a total of 1 061 individuals of 15
Anophelesspecies were captured,
An.sinensiswas 66.26% of total collected mosquitoes,its peak of density occurred at June,6.88 individuals per hour per house,but in October was 1.18 ;
An.minimuswas 3.96% of total collected mosquitoes,peaks of density,in June and September,were 0.40 and 0.29 individuals per hour per house respectively. By human biting catches,a total of 648 individuals of 16
Anophelesspecies were captured.
An.sinensisand
An.minimuswere 46.45% and 16.67% of total collected mosquitoes respectively,and their peaks of density,June and August respectively. Conclusion Mosquito monitor could be effective to know malaria vectors distributions,seasonal fluctuations,which provided evidences for mosquito control,as well as to make out the better control measures to block malaria incidences and transmission.
