insect pest control using low vapour pressure pesticide and a blower at ambient temperature

摘要

An insect pest control method and an apparatus suitable therefor, wherein an air current is supplied to a pesticide-carrying support under non-heating conditions to vaporise and disperse a highly safe pesticidal component from the pesticide, thereby controlling flying pest insects. The pesticide-carrying support is prepared by supporting on a support a pesticidal component of a compound hard to evaporate at normal temperature, preferably, at least one pesticidal component selected from compounds that have vapor pressures lower than 1 x 10-3 mmHg at 30 ‹C, a difficulty in evaporating at normal temperature, and boiling points of at least 120 ‹C/1mmHg. The pesticide support is placed and exposed to a gas current by using a blower device so as to vaporise the pesticidal component from the support into the gas under non-heating conditions. The support is gas permeable so that when the support with a pesticide is placed in the apparatus, the support will not block the gas current going to a vent hole.
