Padrões espaciais da broca da coroa da folha Eupalamides cyparissias (Cramer, 1775) (Lepidoptera: Castiniidae) em coco (Cocos nucifera L.) região tropical

Resumo

A broca-da-coroa-foliar Eupalamides cyparissias (Cramer, 1775) é um importante praga para as culturas do coqueiro (Cocos nucifera Linnaeus) e outras palmeiras (Areacaceae) de importância econômica, atacando a base de folhas, inflorescências e infrutescências acarretando o aumento do abortamento de frutos. O objetivo deste estudo é avaliar a distribuição espacial da taxa de plantas com sintomas de ataque por E. cyparissias das quadras de plantio de coqueiro na Amazônia brasileira, de janeiro a dezembro de 2019, no município de Santa Izabel, Pará, Brasil. A área de estudo é uma fazenda subdividida em 157 quadras de plantio comercial de coqueiro anão verde (C. nucifera). O Índice de Moran Local foi utilizado para avaliar a existência de autocorrelação espacial da variável sintomatologia do ataque de E. cyparissias das 157 quadras com as quadras vizinhas. Há correlação significativa da sintomatologia do ataque por E. cyparissias nas quadras da área experimental, o que indica um padrão de distribuição agregado. Não há correlação significativa entre o ataque pela broca e idade do coqueiro, no entanto há correlação significativa entre o ataque pela broca e proximidade a áreas de mata. Esses resultados indicam que regiões de floresta são focos de infestação pela broca em plantios de coqueiro.
