The measuring device of the noxious insect which utilizes the pheromone trap which measures the number of valve cores from the valve core tonnage which utilizes the dial scale.

摘要

PROBLEM TO BE SOLVED: To provide a counter for counting number of insects captured/killed by a pheromone trap from their total weight measured by a dial scale, capable of accurately determining the number, even when one or more of the captured insects are damaged, because essentially no error is involved in the total weight measured. ;SOLUTION: This counter counts number, of insects captured by a pheromone trap T, comprising a roof 1 supporting pheromone 2 thereunder, and a main body 3 covered by the roof 1 and containing funnels 4 and 7, a baffle 6 under the bottom opening of the funnel 4, automatic shutter 8 under the bottom opening of the funnel 7 to automatically open or shut the opening, container 9 under the shutter 8 to receive the captured insects, dial scale 10 to weigh the captured insects, and vibration-preventive table 11 to support the dial scale 10 wherein the captured insects are collected in the funnel 7 for a given measurement time determined by controlling a CPU controller 12, and then transferred down to the container 9 by opening the automatic shutter 8 after insect capturing time is over, where their total weight is measured by the dial scale 10.;COPYRIGHT: (C)2000,JPO
