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:... |

The tribe Attini (Hymenoptera: Formicidae) comprises 14 genera with approximately 230 described ant species, which are engaged in an obligate mutualism with fungi. The fungus is cultivated inside their colonies, using a variety of organic material as substrate. The fungus is used as food by the ants, and in return, the ants nourish, protect, and disperse their fungal cultivars. Although all species of this tribe cultivate fungi, attine ants are quite heterogeneous in relation to agricultural system, colony size and social structure, substrate preparation behavior, foraging behavior, etc. Agriculture, symbiosis and natural history traits of fungus-farming ants are discussed in this review, as well as future research directions. |

The woodwasp Sirex noctilio Fabricius (Hymenoptera: Siricidae) was introduced in Brazil in 1988 and became the main pest in pine plantations. It has spread to about 1.000.000 ha, at different population levels, in the states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo and Minas Gerais. Control is done mainly by using a nematode, Deladenus siricidicola Bedding (Nematoda: Neothylenchidae). The evaluation of the efficiency of natural enemies has been difficult because there are no appropriate sampling systems. This study tested a hierarchical sampling system to define the sample size to monitor the S. noctilio population and the efficiency of their natural enemies, which was found to be perfectly adequate. |
