Potencial inseticida do óleo essencial de eucalyptus globulus (myrtaceae) no manejo de euschistus heros (hemiptera: pentatomidae)

Abstract

Brazil is one of the largest soybean producers in the world. However, annual soybean production is affected by attacks by hytophagous insects such as the brown stink bug, Euschistus heros (Hemiptera: Pentatomidae), which causes direct and indirect damage to Brazilian soybean crops. The main method of controlling this pest is the use of chemical insecticides. However, in order to ensure public, food and environmental safety, the guarantee of safety in the production of plant-based foods becomes a specification evaluated by the consumer and export market. Thus, the use of Essential Oils (EOs) is a promising alternative to conventional chemical control, due to their insecticidal properties and lower environmental impact. In this work, we investigated the insecticidal potential of Eucalyptus globulus EO in controlling insect pests through a literature review, covering its insecticidal properties and mechanism of action. Furthermore, we performed toxicity bioassays of E. globulus EO on E. heros nymphs and adults. The results revealed the oncentrations of E. globulus EO have an insecticidal effect on different developmental stages of E. heros, proving to be a potential tool in pest management.
