Effect of Pesticides from Organic and Conventional Agriculture on the Activity of Insectivorous Bats and their Potential Prey in the Savanna Ecoregion of Brazil

Orlando Hernández Leal

Aerial insectivorous bats are the arthropod controllers in agricultural areas. This control service is affected by the use of pesticides in conventional agriculture, since it negatively affects the survival of insect populations and therefore reduces bat resources. Organic agriculture has been proposed as an alternative production strategy that avoids the use of pesticides by favoring the natural interactions that occur in crops.

By using acoustic monitoring and identifying the pesticides in nocturnal flying insects from organic and conventional agricultural schemes, we hope to understand how the activity of insectivorous bats and their prey respond to a gradient of agricultural management.
