EXTRATOS VEGETAIS NO CONTROLE DA MOSCA-BRANCA EM MELANCIA

Abstract

A melancia é uma das principais culturas geradoras de divisas e empregos diretos e indiretos no Rio Grande do Norte. Tendo uma produção anual cada vez maior, principalmente no Nordeste, onde há condições climáticas favoráveis à cultura. No entanto, os ataques de pragas estão entre os principais fatores limitantes da produção, tendo seu controle com base na utilização de produtos químicos, que além de aumentar o custo de produção geram acúmulo de resíduos químicos nos frutos. Para contornar este problema é necessário criar novas alternativas para o manejo de pragas, em especial a mosca-branca que se destaca como uma das principais. Em um cenário onde pesquisas relacionadas aos inseticidas de origem vegetal abrem perspectivas e espaço para sua utilização no controle de pragas, o presente trabalho teve como objetivo avaliar o efeito de extratos vegetais no controle da mosca-branca em melancia. Foram realizados testes de livre escolha para alimentação e oviposição utilizando-se quatro extratos aquosos (nim, tiririca, pimentão e sorgo) e testemunha (água), com quatro repetições. Os tratamentos foram dispostos ao acaso em gaiolas formando uma arena cujo meio foi liberado a praga. Concluiu-se que as plantas de melancia pulverizadas com extratos de nim foram menos atrativas à mosca-branca, tanto para alimentação quanto para oviposição, seguido pelos extratos de tiririca, pimentão e sorgo.
