Abstract
In recent years, agriculture has grown considerably in Brazil and as a result, there has been a significant increase in the use of pesticides in crops. In this sense, studies have shown that one of the main causes of the disappearance of insects is directly related to the use of pesticides, which in addition to being a highly aggressive product for the environment, are also harmful to the health of individuals. Based on this assumption, the present work has as main objective to carry out a survey with the main works that describe about the effect of the use of pesticides in the reduction of insects. To carry out the study, a methodological research was used based on a literature review with reading in several books, magazines and scientific articles. After collecting the data, it was concluded that the exacerbated use of pesticides in crops contributes to the mass extinction of several insects, including bees, which are of great importance for the existence of life on the planet.
