Response of adults of Tribolium confusum Duv. (Coleoptera, Tenebrionidae) to treatment of surfaces with a new biinsecticide

Resumo

The results of the experimental investigation of the biological activity of a new biinsecticide in the form of emulsifiable concentrate containing 400 g/1 of pirimiphos-methyl and 10 g/1 of bifenthrin with respect to adults of Tribolium confusum are described. One and 7 days after treatment with biinsecticide applied directly onto insects, the LD-99.9 values were 1.45 ml/m² and < 0.01 ml/m², respectively. For insects contacting with treated concrete surfaces, LD-99.9 was 0.27 ml/m² and 0.1 ml/m² 1 and 7 days after treatment, respectively.
