本研究旨在开发新型林木害虫缓释引诱剂诱芯,选用聚氨酯为缓释基质,通过发泡工艺加工成直径4 cm的缓释球体诱芯,并优化调整诱芯各项指标,日均释放速率超过0.072 g/d。新型缓释诱芯具有释放稳定、环境适应性强和持效性较好的特点。同时,经过气相色谱对新型缓释诱芯释放成分进行分析,其结果与标样引诱剂成分一致。本文的研究为林木害虫的监测提供了能便捷使用的缓释型诱芯产品。
The purpose of this study was to develop a novel entrapment attractant for forest pest release. Polyurethane was used as a sustained-release matrix, which was processed into a 4 cm-diameter slow-released spheroid by the foaming process. Rate exceeds 0.072 g / d. The new sustained-release enticement has the characteristics of stable release, strong environmental adaptability and good holding efficiency. At the same time, the release of the new release of sustained release induced by gas chromatography analysis, the results with the sample attractant composition. The study in this paper provides a convenient and easy-to-use entrained core for the monitoring of forest pests.
