ABSTRACT
The lesser mealworm infests chicken-house litter and is a key pest in modern poultry raising. Its control is inefficient and done mostly using insecticides. Due the lack of information on pest bioecology in Brazil, this study was carried out in Cascavel, state of Paraná, Brazil, in two broiler houses: the first with concrete floor and automatic trough (concrete-automatic) and the second with compact soil floor and manual trough (manual-soil), both covered with wood residues litter. The assessments were made in the houses weekly using traps (15 in the concrete-automatic and 10 in the manual-soil). Temperature was also recorded. In general, there was a tendency to find a lower number of insects in the concrete-automatic house due to difficulty of insect development on this kind of floor. Greater populations were found in the shelter areas due to greater temperature and food concentration throughout the entire period of rearing.
