Integrated pest control adopted by soybean and corn farmers in Londrina, Paraná state, Brazil

ABSTRACT: The metropolitan area of Londrina has the presence of strong agribusiness and agroservices and it is an important center for agricultural production, especially soybean and corn. We evaluated the technical aspects and characteristics of farming and crop handling by the producers of soybean and corn, through a semi-structured questionnaire. Two hundred and forty responses were recorded: 120 from soybean farmers and 120 from corn farmers, which represented 10% of the farmers in the city of Londrina. Farmers reported that bedbugs and caterpillars are the main pests. Farmers use organo-synthetic insecticides as the primary means to control pests, but also employ crop-growing measures such as tillage, crop rotation, and the use of transgenic seeds in the management of insect pests affecting soybean and corn.摘要：隆德里纳（Londrina）都会区拥有雄厚的农业综合企业与农业服务业基础，是重要的农业生产中心，尤以大豆与玉米种植为核心优势领域。本研究采用半结构化问卷，对大豆与玉米种植户的耕作技术细节与作物管理特征展开调研评估。本次调研共回收有效问卷240份，其中大豆种植户与玉米种植户样本各120份，覆盖隆德里纳市10%的种植从业者群体。受访种植户反馈，臭虫与毛虫为当地主要虫害类型。当前种植户主要以有机合成杀虫剂作为虫害防控的核心手段，同时辅以耕作、轮作及转基因种子应用等农艺措施，开展针对危害大豆与玉米的虫害的综合治理工作。
