Provided is a technique comprising blowing air onto a carrier having supported thereon a preparation containing a highly safe pesticidal component to vaporize and diffuse the component from the preparation under non-heating conditions thereby to control flying insect pests. An insect pest control method characterized by preparing a preparation-retaining material by supporting on a carrier a preparation containing a pesticidal component which is hard to vaporize at normal temperature, preferably at least one pesticidal component selected from compounds which are hard to vaporize at normal temperature and have a vapor pressure of lower than 1×10-3 mmHg and a boiling point of not lower than 120°C/1 mmHg, setting the resulting preparation-retaining material, and contacting the preparation with an air current raised by an air blowing means to release the component into the air under non-heating conditions, an apparatus suitable therefor, and a carrier to be used in the preparation-retaining material set in the apparatus characterized by not blocking the air current toward the vent hole of the apparatus are provided.
本发明提供了一种技术,该技术包括向载体吹气,载体上支撑着含有高安全性杀虫成分的制剂,在非加热条件下,使该制剂中的杀虫成分蒸发和扩散,从而控制飞行害虫。一种虫害防治方法,其特征在于通过将含有常温下难以蒸发的杀虫成分的制剂支撑在载体上制备制剂保持材料,该制剂最好至少含有一种杀虫成分,该杀虫成分选自常温下难以蒸发且蒸气压低于 1×10-3 mmHg 和沸点不低于 120°C/1 mmHg 的化合物、将得到的制剂-保留材料设置,并使该制剂与由吹气装置升起的气流接触,以便在非加热条件下将该成分释放到空气中,提供了适用于该装置的设备,以及用于设置在该装置中的制剂-保留材料的载体,其特点是不会阻挡朝向该装置通风孔的气流。
