摘要:

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。

Abstract:

Objective To observe the impact of water quality on the capacity of mosq-ovitrap for monitoring the density of Aedes albopictus and to evaluate the practical value of this monitoring method. Methods During July to August 2012, the peak season of Ae. albopictus, mosq-ovitraps were set in the garden of a hospital in Shenzhen, China to capture Ae. albopictus adults and eggs, and their capacities for capturing Ae. albopictus adults and eggs were compared. Results A total of 240 mosq-ovitraps were set, and 230 were recovered. The oviposition rate was 37.39%; the mosquito-trap rate was 18.26%; 51.16% of adult mosquitoes escaped. The oviposition rate was significantly higher in water from natural environment than in bottled mineral water (χ2=13.79, P<0.01). Using larva hatching as an indicator of positive oviposition response, there was a high similarity between the oviposition rate of Ae. albopictus determined using mosq-ovitraps and the actual oviposition rate (Kappa=0.828, P<0.01). The sensitivity and specificity of mosq-ovitraps for monitoring oviposition of Ae. albopictus were 82.56% and 97.92%, respectively, with a mean area under the ROC of 0.902 (range, 0.853-0.952). Conclusion Mosq-ovitrap has a good performance in monitoring the oviposition of Ae. albopictus, but its capacity for capturing adult Ae. albopictus is not satisfactory. Water quality has an impact on the performance of mosq-ovitrap in monitoring Ae. albopictus. Mosq-ovitrap has a good practical value in monitoring the oviposition of Ae. albopictus.
