Abstract
The effects of NaF, Na2SiF8, BaSiF6 and NasAlF. on adult Thermobia domestica were studied. Each compound was made available to the insects at 4. 8 and 12% concns. in a food consisting of rolled oats. NaCl and sucrose. Median lethal times at all concns. followed the order: NaF < Na2SiF8 < BaSiF6 < Na3AlFe. All these concns. produced 100% mortality: NaF, NaiSiFo and BaSiF8 in about the same time, and NasAlFs in a somewhat longer time. NaF killed 27 to 53% in 24 hours, the other compounds only a few insects in this period. Expts. made on the 12% concns. in which the bait was taken away from the insects after 24 hrs. indicated that the delayed mortalities with the 2 fluosilicates resulted from their slower lethal action, while that of Na3AlF6 is probably due either to repellence or to high lethal dosage.This publication has 3 references indexed in Scilit:
