目的进一步研究诱卵器法在口岸媒介监测现场的应用技术。方法诱卵器法。结果 (1)诱卵器放置不同高度时,0m组和1m组的诱卵指数分别为87.68和83.79,0m组高于1m组(χ2=13.24,P<0.005),0m组和1m组的幼虫密度分别为13.21条/个和11.23条/个,0m组高于1m组(t=2.259,P=0.05);(2)诱卵器放置不同时间时,4d、7d和10 d组的诱卵指数分别为28.00、74.50和76.41,4 d组低于7 d组(χ2=86.54,P=0.000)和10 d组(χ2=92.69,P=0.000),4d、7d和10d组幼虫密度分别为2.095条/个、9.11条/个和11.36条/个,4d组低于7d组(t=2.334,P=0.024),7d组低于10 d组(t=4.691,P=0.000);(3)诱卵指数和幼虫密度呈较为密切的正相关(0 m组r=0.779,P=0.008;1 m组r=0.794,P=0.006),不同监测时间和监测点诱卵指数和容器指数的关系需进一步研究。结论在福州口岸建议诱卵器放置在地面上,放置时间为7～10d,以提高成蚊产卵率,增加敏感性;需进一步研究诱卵器法和布雷图指数、房屋指数和容器指数在口岸地区的关联性,探索评价指标的推广应用。
Objective To further study the application technology of the ovitrap method at the port media monitoring site. Methods Oviposition method. Results (1) The oviposition index of 0m and 1m groups were 87.68 and 83.79 respectively at the different height of the oocysts, while those of the 0m and 1m groups were higher than those of the 1m group (χ2 = 13.24, P <0.005) The density was 13.21 / 11.23 / group, and 0m group was higher than 1m group (t = 2.259, P = 0.05). (2) The indices of larval density in the 4 d, 7 d and 10 d groups were 28.00, 74.50 and 76.41, respectively, and those in the 4 d, 7 d and 10 d groups were lower than those in the 7 d group (χ2 = 86.54, P = 0.000) and 10 d (T = 2.334, P = 0.024) in group 4d and group 10d at 7d (t = 4.691, P = 0.000) ) The oviposition index and larval density were positively correlated (r = 0.779 in 0 m group, P = 0.008; r = 0.794 in 1 m group, P = 0.006). The ovulation index and container index in different monitoring time and monitoring sites Relationship needs further study. Conclusion It is suggested that the ovitrap should be placed on the ground at the port of Fuzhou for a period of 7-10 days to increase the rate of egg production and increase the susceptibility of adult mosquitoes. Further study on the method of ovitrap and Brett index, housing index and container index Port area, explore the application of evaluation index.
