Allelopathy and phytotoxic interactions

In the search for alternative chemical control against Aedes aegypti L., various studies are developedand encouraged in order to find new substances insecticidal plant and in this context essential oilshave been shown to be very promising. Extracted from the essential oils of Lindl Pimenta dioica species(leaves) and Aniba duckei Kostermans (stems) by means of hydrodistillation using a Clevengersystem and promoted its mixture of equal parts. In this study, the larvicidal effect of the mixture ofessential oils extracted from leaves of Pimenta dioica species Lindl and branches of Aniba duckei Kostermanswere evaluated against the mosquito Aedes aegypti (Linnaeus, 1792). The larvicidal activitywas observed based on the percentage of dead larvae, the action was assessed 24 h after treatment.The blend of essential oils had larvicidal activity with LC50 of 113,95 (±2.11) μg mL−¹ and the patternsof eugenol 90,86 (±0,03) μg mL–1 and linalool 305,42 (±0,03) μg mL–1. The results indicate that themixture of essential oils evaluated, is composed of substances that together with the major componentseugenol and linalool provided greater larvicidal effect against the mosquito Aedes aegypti L.
