It is 45cm×45cm and consists of 23 slats (1cm square, 45cm long) nailed 1cm apart on a Z-shaped frame. The practical method for taking count by it is as follows: The grill is placed at the center of fly concentration and the count is made with 30 seconds. In a house, the counts are made at 6 places, 3 indoors and 3 outdoors. The mean of 2 maxima out of 6 counts is considered as the fly index of that house. The mean of 3 maximum indices out of all houses in a certain village containing from about 6 to 15 houses under examination is considered as the fly index of that village. This method of using fly grill has been proved experimentally the most applicable for evaluating housefly control., 長崎大学風土病紀要 1(1), p.60-67, 1959}, pages = {60--67}, title = {蠅格子によるイエバエの撲滅効果の判定法}, volume = {1}, year = {1959} }
