目的观察诱蚊诱卵器在监测白纹伊蚊密度时水质对该蚊诱蚊诱卵的影响,同时评价该监测方法的实用效果。方法在2012年7-8月白纹伊蚊数量高峰季节,选择深圳市某医院花园作为试验现场,用诱蚊诱卵器对白纹伊蚊进行诱蚊诱卵试验,比较评价其诱捕白纹伊蚊成蚊、卵的效果。结果共布放240个诱蚊诱卵器,有效回收230个,诱卵阳性率为37.39%,诱蚊阳性率为18.26%,成蚊逃逸率为51.16%;试验发现生态水(自然环境积水)对白纹伊蚊诱卵率显著高于瓶装矿泉水(χ2=13.79,P<0.01);以是否有幼虫孵化作为衡量诱卵阳性结局的金指标,发现诱蚊诱卵器监测方法观察的白纹伊蚊产卵阳性率与实际产卵阳性率一致性较高(Kappa=0.828,P<0.01),该法监测白纹伊蚊产卵灵敏度为82.56%,特异度为97.92%,试验得到的ROC曲线下面积为0.902(0.853～0.952)。结论诱蚊诱卵器监测白纹伊蚊诱卵效果较佳,但捕蚊效果不甚理想;不同水质对诱蚊诱卵器监测白纹伊蚊效果不同;诱蚊诱卵器监测伊蚊产卵有较好的实用价值。
Objective To observe the effect of water quality on the mosquito-killing and mosquito-luring of mosquitoes when the mosquito-ovipositor is monitoring the density of Aedes albopictus, and evaluate the practical effect of this method. Methods During the peak season of Aedes albopictus from July to August in 2012, a garden of a hospital in Shenzhen City was selected as the test site. The mosquito and egg-laying test of Aedes albopictus was carried out by using the mosquito-ovitrap. The trapping of Aedes albopictus Mosquito mosquito, the effect of eggs. Results A total of 240 mosquito-evacuated eggs were collected, 230 were effectively recovered, the positive rate of oviposition was 37.39%, the positive rate of mosquito was 18.26% and that of adult mosquitoes was 51.16%. The ecological water (natural environment) The Ae. Albopictus oviposition rate was significantly higher than that of bottled mineral water (χ2 = 13.79, P <0.01). Whether the larvae were hatched was the gold index to measure the ovum-positive result, The detection rate of Aedes albopictus was 82.56% and the specificity was 97.92%. The ROC The area under the curve is 0.902 (0.853 ~ 0.952). Conclusion The mosquito-ovitrap is effective in monitoring the infection of Aedes albopictus, but the mosquito-killing effect is not ideal. Different water quality has different effects on the mosquito-ovitrap monitoring of Aedes albopictus. Eggs have good practical value.
