A madeira de mogno, Swietenia macrophylla King, é valorizada no mercado internacional por sua beleza e durabilidade para fins nobres, como mobiliários e decoração. Quaisquer tentativas de plantios comerciais dessa espécie de modo a reduzir a pressão exercida pela sua exploração seletiva invariavelmente fracassam devido à incidência da broca do ponteiro do mogno, Hypsipyla grandella (Zeller). Embora alguns trabalhos tenham obtido relativo sucesso em apresentar técnicas de controle sob aspectos pontuais, ainda não foi estabelecida uma estratégia de manejo integrado que seja prática, econômica e eficiente para H. grandella no Brasil. Este trabalho tem como objetivo rever e atualizar informações sobre o inseto e seu hospedeiro, além de indicar as áreas de...

Este é o primeiro registro do ataque de besouros (Curculionidae, Scolitinae), no Brasil, causando danos em plantios de nim, entre 7 e 10 anos, em Brejinho de Nazaré, Tocantins, constado em junho de 2009. Os insetos foram identificados como, Xylosandrus compactus (Eichhoff), Cryptocarenus diadematus Eggers, 1937 e Hypothenemus sp. Westwood, 1836. Os plantios atacados apresentavam crescimento abaixo do esperado para a região, baixa produção de sementes, desfolhamento acentuado e rebrota intensa nos ramos, seguida por morte de brotos jovens e/ou do ápice do ramo. A ação dos insetos provocou pontos de exsudação intensa de goma nos orifícios provocados. O fato tem similaridade com a síndrome denominada “declínio do nim”, relatada na África.doi:...
