Irradiação e eliminação de pragas: um levantamento de dados sobre as culturas do sul do Brasil

Abstract

The present study consists in the Sterile Insect Technique application using ionizing radiation as a source of insect pests sterilization. The objective of the work is to survey the main pest insects that affect the corn crops, soybeans, beans and wheat in southern Brazil, survey the radiation doses applied and analyze whether they are in accordance with international parameters of IDIDAS. In the bibliographical survey, several pest insects were analyzed, but only two species could be compared to the IDIDAS data, which were Spodoptera frugiperda and Helicoverpa armigera, two pests of agricultural importance. It was verified through data triangulation that the doses used are in partial disagreement with the doses regulated by IDIDAS. As a continuation proposal for this work, at the end some characteristics of Dalbulus maidis (DeLong & Wolcott) are presented as a form of reproduction, a form of population growth and the development cycles of the species, in order to apply the sterilization technique to this insect pest, which affects the corn crop.
