First record of Eremionycha bahiana (Boheman) infesting Tabebuia sp

The Chrysomelidae is the second largest family regarding the number of species within the order Coleoptera. It consists of 37,000 species grouped into 19 subfamilies. Among these subfamilies, most presents species considered agricultural pests ( Chaboo, 2007 ; Laumann et al., 2004 ; Stolar and Bidau, 1997 ). The subfamily Cassidinae has about 6,000 species distributed into 324 genera. They can be found worldwide, with a higher diversity in the tropics, especially in South America and less frequently in North America and Australia ( Chaboo, 2007 ). According to Barney et al. (2007) , the subfamily Cassidinae currently includes two previously recognized subfamilies: Hispinae (“hispines” or leaf-mining beetles) and Cassidinae (tortoise beetles). The species of this subfamily feed on leaves and are associated with the Boraginaceae, Bignoniaceae, Asteraceae, Convolvulaceae and Solanaceae families, and also associated with other no host plants ( Boldt and Staines, 1993 ; Buzzi, 1988 ; Virkki et al., 1992 ). Coleoptera specimens of all developmental stages were collected manually in plants of the genus Tabebuia sp. (Bignoniaceae) at the Agricultural Sciences Center, Socopo campus, Teresina, Piauí state, located in the campus of the Federal University of Piauí (UFPI). They were housed in small cages (transparent plastic pots, 500 mL capacity) and their development was observed at laboratorial conditions. Samples of these insects were sent to a taxonomist for species identification. Images of specimens were obtained using the stereo microscope Hirox at the São Paulo University (Esalq/USP, Piracicaba, SP) Electron Mycroscopy Laboratory and the Nikon SMZ1500 at the Federal University of Lavras (UFLA, Lavras, MG) Electron Microscopy Laboratory.(AU)

Coraliomela brunnea brunnea: morfologia do adulto e sinonímias (Coleoptera, Chrysomelidae)

The adult of Coraliomela brunnea brunnea (Thunberg, 1821) is redescribed and illustrated including new morphological characters. Coraliomela brunnea collaris (Guérin-Méneville, 1840) and C. brunnea nigripes (Guérin-Méneville, 1840) are considered synonyms of C. brunnea brunnea.

Descriptions and biological notes of immatures of Microctenochira Difficilis (Coleoptera, Chrysomelidae, Hispinae, Cassidini)

Descriptions and illustrations of egg, larva and pupa of Microctenochira difficilis (Boheman, 1855) are presented for the first time. Biological notes and bionomic informations are also included. Eggs, larvae, pupae and adults were collected on Tabebuia sp. (Bignoniaceae) in Monjolinho arboretum at Centro Experimental Santa Elisa, Campinas, State of São Paulo, and kept in laboratory for rearing.

Occurrence of Spaethiella coccinea Boheman (Coleoptera: Chrysomelidae, Hispinae) on Theobroma grandiflorum [Willdenow ex Sprengel] Schumman, (sterculiaceae), in Manaus, Amazonas, Brazil

A preliminary study on the ocurrence of Spathiella coccinea Boh. (Coleoptera) on Theobroma grandiflorum (cupuassu), native Amazonian fruit plant, are reported. S. coccinea is known to feed on leaves of many species of palm, and has been found in Elaeis guineensis (Palmaceae) leaves. From September 1994 to February 1996 observations were made on the behavior and seasonal aspects of S. coccinea and larvae, pupae and adults found on the leaves of cupuassu were hand collected. The highest number of insects was found in the rainy season February 1995.

A ocorrência de Spathiella coccinea Boh. em plantas de Theobroma grandiflorum Schum. (cupuaçuzeiro), fruteira nativa da região Amazônica é aqui registrada. S. coccinea é conhecida como um Coleoptera que se alimenta de folhas de palmeiras de diversas espécies tendo sido encontrado na região de Tefé, alimentando-se de folhas de dendezeiros Elaeis guineensis. Durante dezoito meses foram feitas observações sobre o comportamento sazonal desses besouros, coletando-se manualmente larvas, pupas e adultos sobre e sob as folhas de cupuaçuzeiros. Encontrou-se o maior número desses indivíduos nos meses correspondentes ao período mais chuvoso.

Coleopterofauna visitante de Theobroma grandiflorum Schum. (Sterculiaceae) de uma plantação nos arredores de Manaus, Amazonas, Brasil1

The cupuassu (Theobroma grandiflorum, Sterculiaceae) is a native Amazonian fruit tree that about its entomological informations had been demonstrated the highest insects diversity princi-pallyColeoptera. During in a period of 12 consecutive months, manual collections were realized using insecticide and flight interception traps in a private plantation of cupuassu in Manaus and 1.212 individuals of Coleoptera visitors of Theobroma grandiflorum were collected Some plants aspects phenologies were done. The most great abundance was registered in plants exposed to the sun, in plants with flowers and without fruits, and plants localized in level and steep areas. Seasonal differences were also considered, finding a greater frequency of samples in the months corresponding to the less rainy period (from June to November). The quantity of samples collected (and the families of Coleoptera) was correlated with the period of collection, the morning hours presenting a greater sample quantity. From the Coleoptera found visiting the cupuassu plants, 32 families were collected and identified, the most abundant of which were Chrysomelidae 25.17%, Curculionidae 18.08%, Staphylinidae 17,57%, Coccinellidae 12.46%. The species Homophoeta aequinoctialis, Exora obsoleta, Spaethiella coccinea (Chrysomelidae). Colobothea hirtipes, Clorida curta,Compsibidion maronicum, Heterachthes pelonioides (Cereambycidae) and Marshallius multisignatus (Curculionidae), were identified. The samples of Desmobaris and Heilipus were found on leaves spronts and flowers of the plants being considered pest of young cupuassu plants, (Phytotribus), however their relation with the plant is not know yet. The Spaethiella coccinea (Chrysomelidae, Hispinae) was observed and collected feeding on leaves of the cupuassu plant.

O cupuaçu (Theobroma grandiflorum Schumman), é uma planta frutífera nativa da Amazônia, com uma diversificação na entomofauna encontrada, registrando-se maior abundância na ordem Coleoptera. Em uma plantação nos arredores da cidade de Manaus usando-se métodos de coletas, manuais, com aplicação de inseticida (método de queda) e armadilhas de interceptação de vôo foram coletados durante 12 meses consecutivos, 1.212 exemplares de Coleoptera. Alguns aspectos em relação a fenologia e localização das plantas foram abordados. A maior abundância foi registrada em plantas localizadas em áreas de relevo plano expostas ao sol, com flores e sem frutos. Encontrou-se maior frequência nos meses correspondentes ao período menos chuvoso (de junho a novembro), registrando-se maior quantidade de exemplares no horário matutino. Foram identificadas 32 famílias e as mais abundantes foram Chrysomelidae 25,17%, Curculionidae 18,08%, (incluindo Scolytinae e Platypodinae), Slaphylinidae 17,57% e Coccinellidae 12,46%. Foram identificados indivíduos dos gêneros Palaminus (Staphylinidae), Phenrica, Asphaera, Colaspis, Homophoeta, Heilipus (Chrysomelidae), Desmobaris, Phitotribus, Comptocerus (Curculionidae) e das espécies Homophoeta aequinoctialis, Exora obsoleta, Spaethiella coccinea (Chrysomelidae), Colobothea hirtipes, Clorida curta, Compsibidion maronicum, Heíerachthes pelonioides (Cerambycidae) e Marshallius multisignatus (Curculionidae). Os indivíduos de Spaethiella coccinea foram observados alimentando-se das folhas, Desmobaris e Heilipus foram encontrados alimentando-se dos brotos das folhas e das flores sendo considerados pragas para mudas das plantas. A relação dos indivíduos do gênero Phitotribus com a planta ainda não é conhecida.
