Survival of red flour beetles (Coleoptera : Tenebrionidae) on concrete partially treated with cyfluthrin
Journal of Economic Entomology 92 (4), 981-987
Abstract: Different densities of red flour beetles, Tribolium castaneum (Herbst), were exposed for 1 h on concrete with 20, 40, 60, or 80% of the total area treated with 200 mg/m² of 20% [(AI)] cyfluthrin wettable powder. Residual bioassays were repeated 4 times at monthly intervals. Population density did not affect knockdown or survival of red flour beetles. The percentage of beetles still mobile after they were exposed decreased as the percentage of treated area increased, and there was no significant difference with respect to month. Survival decreased as the percentage of treated concrete increased and increased with each successive monthly bioassay. When beetles were knocked down after exposure, survival was higher for beetles knocked down on untreated concrete compared with treated concrete in 9 out of 16 comparisons. The presence of untreated pockets within a treated area could enable some of the insects to partially survive exposure to cyfluthrin in field applications.
