ABSTRACT
Background:
Even though insecticides are managed and the period of sanitary emptiness in poultry is respected, the elimination of Alphitobius diaperinus may not be successful. The use of essential oils of plant origin presents as a good alternative in the substitution of insecticides with synthetic molecules, since they are easy to obtain, with rapid degradation and without risk of residues for non-target organisms. The main objective of the present study was to examine whether Cinnamomum zeylanicum oil reduces Alphitobius diaperinus (Panzer) (Coleoptera Tenebrionidae) infestations under experimental conditions, without causing toxicity to broilers chicks exposed to treated litter.Materials, Methods &Results:
The experimental design was completely randomized, with four replications per treatment. The treatments were as follows solvent control using the diluent Dimethyl Sulfoxide 5% (oil diluent); chemical control using 5 g/m² cypermethrin; one spray of C. zeylanicum 5% oil; and two sprays of C. zeylanicum 5% oil. Each experimental unit was infested with 150 lesser mealworm adults. At 15 days of the broiler chicks life, blood was collected for biochemical analysis (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total protein, albumin, globulin, triglycerides and uric acid), and liver fragments were isolated for histopathological analysis. Using TupeTrap devices, we counted lesser mealworm 40 days after treatment. The treatments did not alter biochemical variables, and did not cause histopathological lesions in liver. The treatments with C. zeylanicum 5% oil with one and two sprays efficiently reduced lesser mealworm infestation compared with solvent control. Cypermethrin treatment had no effect.Discussion:
Many of the commercial products present low effectiveness in the control of A. diaperinus, since the target organisms develop resistance to the product.[...]Palavras-chave
