Cacao farming is considered the main perennial crop established in the southwestern state of Pará. Medicilândia is the largest producer of cocoa beans in Brazil. The culture presents a system of production with recognized social and environmental economic sustainability because it is inserted in Agroforestry Systems. It is in this municipality that the project “Roça Sem Queimar: systematization and analysis of the productive, ecological and socioeconomic aspects” was developed. The objective of this work was to survey harmful insects, natural enemies and disease levels in traditional and non-fire farms. Field surveys were carried out in two different periods of the year and three extracts of roças ages. Among the pests, highlight the monalonium bug. In relation to the natural enemies, the bug was identified, the red ant and an entomopathogenic fungus. The level of witch’s broom was lower in the system without fire compared to the traditional one, especially in the extracts over six years. These results reaffirm the agroecological importance of non-fire plantations in the maintenance of bio-controllers.
可可种植被认为是西南部帕尔州的主要多年生作物。印度是巴西最大的可可豆生产国。这种文化是一种公认具有社会和环境经济可持续性的生产系统，因为它被纳入农林业系统。正是在这个城市，“roa Sem Queimar:生产、生态和社会经济方面的系统化和分析”项目得到了发展。这项工作的目的是调查传统和非火农场的有害昆虫、天敌和疾病水平。实地调查是在一年中的两个不同时期进行的，并对三种植物进行了提取。在这些害虫中，值得注意的是单孢虫。在天敌方面，鉴定出了小虫、红蚂蚁和一种昆虫病原真菌。无火系统中女巫扫帚的含量低于传统系统，特别是在六年以上的提取物中。这些结果重申了非火人工林在维持生物控制方面的农业生态学重要性。
