Resumo
O cacau é um recurso estratégico porque abriga alta biodiversidade e é uma fonte confiável de divisas. En Venezuela su productividad se ve afectada principalmente por hongos y squilos. O objetivo é avaliar a influência da estrutura do cultivo de cacau no nível do dano causado por esquilos às mazorcas. A estrutura da vegetação é definida em 15 fazendas midiendo a biomasa do árbol de cacau, a magnitude da cobertura das árboles de sombra, o número de cultivos associados, a presença de árboles frutas alternativas e o tipo de sucessão ecológica presente no entorno. Foi calculado el % de daño e foram utilizadas testes não paramétricas para processar os dados. El daño fue mayor en cultivos com menor cobertura de sombra, maior número de cultivos associados e de frutas alternativas. Os squilos ussaram as bagas de cacau de manera oportunista, pero prefirieron outros frutos. Conclui-se que as vainas podem ser o alimento complementar para los squilos na medida em que a plantação de cacau é mais completa e tem uma conexão com o bosque. A cobertura de sombra não influenciou diretamente nos squilos, mas é crucial para as aves depredadoras que são mais sensíveis às perturbações.
