Factors responsible for variable results in small chamber fumigation tests were studied to develop a reliable and sensitive method for detecting susceptibility differences between insect strains. Quart Mason jars; weighed fumigant-filled glass capillary tubes; absorbent paper; and screen cages attached under jar lids and charged with insects through readily sealed openings constituted the apparatus selected. At room temperature a two-hour evaporation period, five-hour exposure period and 14- to 20-day post-exposure period proved best. The effects of day-to-day variability were minimized by testing each material along with a standard and making comparisons based on susceptibility indices. [...]
