Effectiveness of Biocidal Paint Containing Permethrin, Ultramarine and Violet 23 Against <i>Alphitobius diaperinus</i> (Panzer) (Coleoptera: Tenebrionidae) in Laboratories and Poultry Houses

Reducing <i>Alphitobius diaperinus</i> in poultry production is a difficult task. However, attempts should be made to control the insect pest, as it poses a serious threat to the life and health of the chickens, as well as the workers on a farm. Our research was conducted in two stages to assess the effectiveness of the biocidal paint against <i>A. diaperinus</i>, containing active substances such as permethrin and a mixture of ultramarine and violet 23. In the first stage, under laboratory conditions, after 22 days, 100% mortality of <i>A. diaperinus</i> larvae and adults was achieved. This allowed us to assume that the biocidal paint may also be effective in poultry houses. In the poultry house where biocidal paint was applied, the number of insects decreased continuously alongside the sampling dates. In both research stages, the biocidal paint proved more effective against <i>A. diaperinus</i> than traditional limewash, and also the time to effective interaction of the paint was noted. Additionally, it was observed that the larvae were more susceptible to the active substances than adults. The research was practical, however, further analyses are necessary to fully control <i>A. diaperinus</i>, especially in poultry houses.
