在商业诱捕器上加装塑料漏斗，设计了一种诱捕活捉褐家鼠成虫的诱捕器。漏斗被设置在一个桶里，以防止被收集的成年人逃跑。在实验条件下，平均每天约有30%的甲虫从带有漏斗的桶中逃脱。在松林内设置21个诱捕器，每3-4天收集一次捕获的甲虫。每个普查期间的逃逸率估计为34-56%，与实验室实验估计值吻合较好。在阳光明媚的夏天，桶里的温度达到45-49°C，这似乎对甲虫是致命的。用铝箔覆盖的桶的最高温度比未覆盖的桶低约6℃，但仍然太热，无法使捕获的甲虫存活。
A trap for capturing Monochamus alternatus adults alive was devised by adding a plastic funnel to a commercial attraction trap. The funnel was set in a bucket to prevent collected adults from escaping. About 30% of collected beetles escaped from buckets with funnels per day on average under experimental conditions. Twenty-one traps were set in pine stands and captured beetles were collected every 3-4 days. The escape ratio during each census period was estimated at 34-56%, corresponding well to the value estimated from the laboratory experiment. On sunny summer days, the temperature in the buckets reached 45-49°C, which seemed to be lethal to the beetles. The maximum temperature in buckets covered with aluminum foil was about 6°C lower than in the uncovered bucket, but was still too hot to keep captured beetles alive.
