[目的]比较改良瓶诱法和一般瓶诱法在蟑螂密度监测中捕获蟑螂的优劣。[方法]在4～10月,用普通瓶和改良瓶按1∶1的配比布放捕捉蟑螂。[结果]普通瓶的阳性瓶百分比为48.6%,蟑螂密度指数为0.60只/瓶;改良法的阳性瓶百分比为64.3%,高于一般法,蟑螂密度指数为0.97只/瓶。[结论]瓶诱法进行蟑螂密度监测中,改良瓶优于一般瓶。
[Objective] The aim of the study was to compare the advantages and disadvantages of improved vial induction and general vial induction in cockroach density monitoring. [Method] Between April and October, cockroaches were caught and placed in a ratio of 1: 1 with ordinary bottles and modified bottles. [Result] The percentage of positive bottles in common bottles was 48.6%, and the density index of cockroaches was 0.60 / bottle. The positive percentage of modified bottles was 64.3%, which was higher than that of common method. The density index of cockroaches was 0.97 / bottle. [Conclusion] The bottle-induced method for cockroach density monitoring, modified bottle better than the general bottle.
