RESUMO Os cupins sem soldados (Blattodea: Isoptera: Apicotermitinae) são um grupo pequeno e taxonomicamente pouco conhecido, principalmente na região neotropical. Neste artigo descrevemos um novo gênero monotípico Caputitermes gen. nov., que possui a junção mesênetero-P1 reta e ausência de segmento misto. A espécie Caputitermes dimorphus sp. nov., se destaca por ter dois tipos de operários.

ABSTRACT Soldierless termites (Blattodea: Isoptera: Apicotermitinae) are a small and taxonomically poorly known group, especially in the Neotropical region. In this paper we describe a new monotypic genus Caputitermes gen. nov. with a straight mesenteron-P1 junction, and absence of mixed segment. The species Caputitermes dimorphus sp. nov., which stands out for having two types of workers.

ABSTRACT Several factors limit cowpea quality and yield, such as the choice of a cultivar better adapted to the region, the ideal sowing season, as well as diseases and pests. Aimed to evaluate the effect of different sowing seasons on the population dynamics of pest insects of cowpea crops. The study was carried out during the dry season, the rainy season, and the season recommended for sowing by the Experimental Farm of the Federal University of Amazonas (FAEXP–UFAM), Brazil. A total of 33 weekly collections were carried out during the three sowing seasons, distributed in two ways according to the phenological stage of the crop: manual collection per linear meter of plantation and entomological scanning net. The faunistic analysis detected the pest insects Acromyrmex laticeps nigrosetosus, Cerotoma arcuata, Crinocerus sanctus, Euschistus heros, Horciasinus signoreti, Liriomyza sativae, and Nezara viridula. Of these species, H. signoreti stands out for being recorded for the first time as predominant in cowpea crops in the Brazilian state of Amazonas. Infections by hemipterans such as C. sanctus, E. heros, H. signoreti, and N. viridula were detected throughout the study, regardless of the sowing season, except for H. signoreti, which was dominant in all three seasons. The highest infestation of C. arcuata occurred during the recommended sowing season for cowpeas (June to August). According to the Jaccard index, plantation I e II share 86% of the species. This study provides important information to programs in insect control and management and to the agronomic decision-making process.

RESUMO: Esse é o primeiro registro, para o estado do Amazonas, da ocorrência de Anastrepha striata em frutos de abiu (Pouteria caimito, Sapotaceae) e de carambola (Averrhoa carambola, Oxalidaceae). As associações entre A. striata e Inga fagifolia (Fabaceae), A. striata e Passiflora nitida (Passifloraceae) e Anastrepha distincta e P. nitida são inéditas para o Brasil.

ABSTRACT: This is the first record, for the state of Amazonas, of the occurrence of Anastrepha striata in fruits of abiu (Pouteria caimito, Sapotaceae) and star fruit (Averrhoa carambola, Oxalidaceae). The associations between A. striata vs Inga fagifolia (Fabaceae), A. striata vs Passiflora nitida (Passifloraceae) and Anastrepha distincta vs P. nitida are new for Brazil.

A Coleção do Museu Paraense Emílio Goeldi (MPEG), na cidade de Belém, Estado do Pará, Brasil, possui 65 amostras que são exemplares-tipos de Isoptera, representando 26 espécies (21 holótipos e 5 parátipos) pertencentes a 18 gêneros. Este trabalho lista o número de espécimes de cada casta em cada série-tipo, localidade tipo com as coordenadas geográficas, coletor e dados da coleta.

The collection of the Museu Paraense Emílio Goeldi (MPEG), in the city of Belém, State of Pará, Brazil, has 65 samples of type-specimens of Isoptera, representing 26 species (21 holotypes and 5 paratypes) of 18 genera. This paper lists the number of specimens of each caste in each type series, type localities with geographical coordinates, collectors, and dates of collection.

O cultivo de camu-camu Myrciaria dubia (H.B.K.) Mc Vaugh tem apresentado inúmeros problemas fitossanitários, dentre os quais, Tuthillia cognata Hodkinson et al. (Hemiptera: Homoptera, Psyllidae), que constantemente é citada como praga secundária. Os objetivos deste estudo foram determinar o nível e a intensidade de infestação (%) por T. cognata e estudar aspectos do ciclo biológico e do comportamento de T. cognata, em plantios experimentais de camu-camu. Foram selecionados, de forma aleatória, 17 e 14 exemplares nos plantios I e II, respectivamente. Para cada uma das variáveis estudadas, foram calculados a média aritmética, o desviopadrão, a variância e a amplitude de variação. Foi verificado um nível de infestação de 82% (plantio I) e 57% (plantio II), uma intensidade de infestação de 94% (plantio I) e 75% (plantio II) e uma média de seis ninfas/folha em cada plantio, o que indica que T. cognata representa uma das pragas-chave dessa cultura. Foram observados adultos de Chrysoperla sp. (Neuroptera: Chrysopidae) e ninfas de Reduviidae (Hemiptera: Heteroptera), que podem atuar como prováveis agentes de controle biológico de T. cognata.

The cultivation of camu-camu Myrciaria dubia (H.B.K.) Mc Vaugh has presented countless phytosanitary problems, among them, Tuthillia cognata Hodkinson et al. (Hemiptera: Homoptera, Psyllidae), which often is noticed as a secondary pest. This study aimed to determine the level and the intensity of infestation (%) for T. cognata, as well as to study the biological cycle and behavioural aspects of T. cognata, in experimental plantation of camu-camu. 17 and 14 specimens from plantation I and II, respectively, were randomly selected. The arithmetic average, the standard deviation, the variance and the total amplitude were calculated for each studied variable. A level of infestation of 82% (plantation I) and 57% (plantation II), an intensity of infestation of 94% (plantation I) and 75% (plantation II) and an average number of six nymphs/leaf in each plantation were found, indicating that T. cognata is one of the key pest on this culture. Adults of Chrysoperla sp. (Neuroptera: Chrysopidae) and nymphs of Reduviidae (Hemiptera: Heteroptera), which can to be considered as probable biological control agents for T. cognata, were found in the plantations.
