BIOMARCADORES COMPORTAMENTAIS E MATAGÊNICOS EM coturnix coturnix japonica EXPOSTAS À ABAMECTINA

Abstract

The need to produce food, in order to meet the world population, demands the use of agrochemicals. However, its extensive use has brought serious environmental problems and risks, as they may cause changes in the environment, whether by altering the biological communities, or by the physical, chemical-chemical and chemical changes that may occur in the abiotic components of natural ecosystems. In this context, the effect of chronic exposure of Japanese quail (Coturnix coturnix japonica) to abamectin (acaricide and insecticide) and its possible interference in different behaviors typical of the species was evaluated. For this, 32 animals, aged between 35 and 40 days, were distributed in 3 groups (control, ABA 1% and ABA 10%), the "control group": composed of quails exposed only to drinking water, without abamectin; "ABA 1% LC50 group", composed of water exposed animals containing 15.5 mg ai / L abamectin (via Kraft® 36EC commercial formulation) and "ABA 10% LC50 group", composed of water-exposed birds containing 155, 0 mg / ml abamectin. At the end of the 40 days of exposure, the animals were submitted to open field tests (locomotion), object recognition (social motivation), aggressiveness (social interaction), predator response (survival) and social aggregation (predatory vulnerability). The results showed that the animals of the 1% ABA and 10% ABA groups showed a failure to detect a predator, an increase in the level of fear and lack of social motivation. It can be concluded that abamectin causes neurotoxicity and cytotoxicity in the studied bird model.
