摘　　要：目的通过现场比较实验，进一步研究诱卵杯、诱蚊诱卵器在现场的使用技术，为推广现场应用和评价提供技术依据。方法2006年在白纹伊蚊密度高峰期（6-10月），选择3个市区、1个郊区的居民小区、公园、学校和医院的绿化地带，分别放置含有脱氯水或稻草浸出液的WHO诱卵杯、诱蚊诱卵器，观察其在不同放置高度、不同放置时间内的幼虫阳性情况，并于8—10月在实验环境周围同步检查容器指数（CI）、房屋指数（HI）、布雷图指数（BI），研究2种监测方法与传统监测方法监测结果的关联度。结果（1）诱卵杯幼虫阳性指数为43．16％，诱蚊诱卵器幼虫阳性指数为27．98％，两者差异有统计学意义（X^2=13．73，P≤0．01），诱蚊诱卵器6—10月诱蚊密度指数（MDI值）在1．79～1．38之间，平均1．56。（2）以稻草浸出液和脱氯水进行监测的数据表明，前者的成蚊容器阳性率、MDI值和幼虫密度明显高于后者，诱蚊诱卵器中稻草浸出液成蚊阳性率是脱氯水的2倍左右。（3）用含有稻草浸出液和脱氯水的2种容器进行监测，发现在市区和郊县环境放置14d后幼虫阳性率和幼虫密度均明显高于7d。（4）放置在地面的诱卵杯和诱蚊诱卵器，幼虫阳性率分别为40．00％和28．12％；而放置在离地1m处的幼虫阳性率分别为16．67％和9．38％，表明放置高度对诱捕效果有较明显的影响（诱卵杯高度问：矿=23．74，P≤0．01；诱蚊诱卵器高度间：矿=3．70，P≤0．05）。（5）8—10月现场实验发现诱蚊诱卵器监测获得的幼虫阳性率与传统监测方法获得的HI、CI、BI指数间存在正相关关系（r=0．7627；与HI，r=0．9832；与CI，r=0．9817；与BI，r=0．7498），诱卵杯监测获得的幼虫阳性率与传统监测方法获得的HI、CI、BI指数间也有一定的正相关关系（r：0．4574；与HI，r=0．9751；与CI，r=0．6313�Objective To study the application techniques of two monitoring methods for Aedes albopictus in the filed. Methods Put the mosq-ovitrap and ovitrap containing straw liquid or dechlorinated water at the households, hospitals, schools and park of 3 city zones and 1 suburb selected, and then observe the larval positive rates at different heights and different times from June to October of 2006. As the same time, investigate the larval indices such as HI, CI, BI around the surroundings of those places. Results （1） The larval indices of the ovitrap and mosq-ovitrap were 43.16% and 27.98% respectively, and there was significant difference between them （X^2 = 13.73, P≤0.01 ）. MDI value of mosq-ovitrap was 1.79-1.38 from June to October. （2） On monitoring by the two containers with straw liquid or dechlorinated water, the results showed that MDI, larval density and adult positive rate of the former were obviously higher than those of the latter. The adult positive rate of mosq-ovitrap with straw liquid was 2 times of that with dechlorinated water. （3） The larval index and larval density of two tested container put for 14 days was higher than that for 7 days. （4） Put the mosq-ovitrap and ovitrap on ground, the larval positive rates were 40.00% and 28.12% respectively. And the larval positive rates were 16.67% and 9.38% respectively when put them in the 1 m positionon above the ground. It suggested that the putting height of the containers had more significantly effect on epigarnic efficiency （ovitrap X^2 = 23.74, P≤0.01 ; mosq-ovitrap X^2 = 3.70, P≤0.05）. （5） The larval positive indices of two the containers have positive correlation with the HI, CI, t3I index of traditional monitoring method （mosq-ovitrap r 0.7627, HI r= 0.9832; CI r= 0.9817; BIr =0.7498; ovitrap r=0.4574; HI r-0.9751; CI r= 0. 6313; BI r =0. 5301）. Conclusion The methods of Mosq-ovitrap and ovitrap were effective for the monitoring of larvae of Aedes albopictus.
