【Abstract】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 A nopheles species were collected , A n. sinensis is the predominant species (63. 72 %) ,its peaks of population density occurred in May and J une , 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 A n. 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 A nopheles species were captured , A n. sinensis was 66. 26 %of total collected mosquitoes , its peak of density occurred at J une , 6. 88 individuals per hour per house , but in October was 1. 18 ; A n. minimus was 3. 96 % of total collected mosquitoes , peaks of density , in J une 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 A nopheles species were captured. A n. sinensis and A n. minimus were 46. 45 % and 16. 67 %of total collected mosquitoes respectively , and their peaks of density , J une and August respectively. Conclusion Mosquito monitor could be effective to know malaria vectors distributions , seasonal fluctuations , whichprovided evidences for mosquito control , as well as to make out the better control measures to block malaria incidences and transmission.
