O eucalipto sofre severos danos por cupins durante a implantação das mudas no campo, sendo considerada praga importante da cultura. No ecótono Cerrado/Pantanal não existem estudos anteriores sobre a ocorrência de cupins em plantações de eucalipto. O objetivo foi conhecer a riqueza de cupins, sua distribuição nos tratamentos e a influência do ambiente nas populações de cupins, nos híbridos de eucalipto Eucalyptus grandis x E. camaldulensis e Eucalyptus urophylla x E. grandis com fertirrigação por gotejamento, microaspersão e sequeiro. O delineamento experimental foi o de blocos ao acaso, com 10 tratamentos e quatro repetições. A riqueza de cupins foi associada pela Análise de Correspondência e pela influência climática pela Análise de Componentes Principais. Os cupins foram coletados de março de 2012 a fevereiro de 2013, em 432 parcelas de 4,0 x 2,25 m, em uma área de 3 ha, seguindo o protocolo rápido de coleta, observando-se a serrapilheira, e até 30 cm de profundidade no solo. Obtiveram-se 18 espécies de Termitidae, Rhinotermitidae, Heterotermitinae, Syntermitinae, Apicotermitinae e Nasutitermitinae. Nos tratamentos com gotejamento, houve a maior frequência total, com presença de 18 espécies de cupins nos híbridos, sem associação significativa. A associação entre espécies de cupins e tratamentos constituiu quatro grupos. A precipitação e a umidade relativa do ar influenciaram significativamente na comunidade dos cupins. Portanto, a maior riqueza de espécies ocorreu nos tratamentos com gotejamento. Das espécies consideradas pragas de eucalipto, destacou-se Syntermes molestus, pela sua maior frequência durante as coletas. Ocorreu diferença significativa na distribuição das espécies de cupins associadas aos tratamentos entre os meses de coleta. A riqueza e a distribuição dos cupins são influenciadas ao longo do ano pelos diferentes manejos de irrigação em áreas de cultivo de eucalipto.

Eucalyptus suffers severe damage by termites during deployment of seedlings in the field, and it is an important pest of the crop. In the ecotone Cerrado/Pantanal there are no previous studies on the occurrence of termites in eucalyptus plantations. The objective was to know the richness of termites, their distribution in treatments and the influence of the environment on the population of termites in Eucalyptus hybrid Eucalyptus grandis x E. camaldulensis and Eucalyptus urophylla x E. grandis with fertigation by dripping, micro sprinkler and only rain (dryland). The experimental design was a randomized block design with 10 treatments and four replications. The richness of termites was associated by Correspondence Analysis and climate influence by Principal Component Analysis. Termites were collected from March 2012 to February 2013, in 432 plots of 4.0 x 2.25 m , in an area of 3 ha, following the rapid protocol for collection, observing the litter and up to 30 cm into the ground. 18 species were obtained of Termitidae, Rhinotermitidae, Heterotermitinae, Syntermitinae, Apicotermitinae and Nasutitermitinae. In treatments with dripping there was the highest total frequency with the presence of 18 species of termites in the hybrids, and no significant association. The association between termite species and treatments constituted four groups. Rainfall and relative humidity significantly influenced the termites community. Therefore, the highest species richness occurred in treatments with dripping. Among the species considered as pests of eucalyptus, Syntermes molestus stood out by their greater frequency during collections. There was a significant difference in the distribution of termite species associated with treatments between the months of collection. The richness and the distribution of termites are affected throughout the year by different irrigation managements on plantations of eucalyptus.

In addition to β-sitosterol, stigmasterol, phaeophitin A, luteolin, kaempferol, quercetin, (+)-catechin, quercetin-3-O-α-L-rhamnopyranoside, rutin, and p-hydroxy-benzoic acid, six known sesquiterpenes, namely (rel)-2β,6β-epoxy-5β-hydroxy-isodaucane, oplopanone, 1β,6α-dihydroxy-4(15)-eudesmene, caryophyllene oxide, α-cadinol, and spathulenol, were isolated from the leaves of Pterodon pubescens (Leguminosae) growing in the Cerrado of Mato Grosso do Sul, Brazil. The (rel)-2β,6β-epoxy-5β-hydroxy-isodaucane corresponds to the correct structure of homalomenol D. The sesquiterpene oplopanone, which bears a modified cadinane skeleton, is being reported for the first time in this genus. The structures of the compounds were determined on the basis of spectral data (MS, IR, and NMR-1D and 2D) and subsequent comparison with data reported in the literature.

Fruit flies (Diptera, Tephritidae) and their parasitoids on cultivated and wild hosts in the Cerrado-Pantanal ecotone in Mato Grosso do Sul, Brazil. Information on frugivorous flies in cultivated or wild host plants and their parasitoids in the Cerrado-Pantanal ecotone in Aquidauana, Mato Grosso do Sul is presented and discussed. Fruit fly samples were collected weekly in specific fruit trees, and McPhail® traps were installed in the same trees for a period of two years. The fruit flies infested ripe and unripe fruits of Averrhoa carambola L., Schoepfia sp., Psidium guajava L. and Pouteria torta (Mart.) Radlk and mature fruits of Anacardium occidentale L. and Inga laurina (Sw.) Willd. Nineteen fruit fly species were obtained with the combination of sampling methods (collecting fruits and trapping), nine of them obtained with both methods, five found only in fruits and five only in traps. This is the first record of Anastrepha striata Schiner in a species of Sapotaceae, as well as for A. castanea Norrbom and A. daciformes Bezzi in Schoepfia sp. (Olacaceae), and for A. distincta Greene in fruits of P. guajava in the state of Mato Grosso do Sul. Fruit collections simultaneously associated with capture of fruit flies by McPhail traps in the same host plants are essential to understand the diversity of fruit flies and their relationship with hosts and parasitoids. Species of Braconidae and Pteromalidae were recovered, where Doryctobracon areolatus (Szépligeti) was the most abundant parasitoid in larvae of tephritids infesting both cultivated and wild host fruits.

O feijão-caupi (Vigna unguiculata (L.) Walp.) é uma importante fonte de alimento. Na região centrooeste do Brasil, poucos são os estudos desenvolvidos com essa cultura. Assim, foram desenvolvidos experimentos, em condições de campo, em Aquidauana, MS, visando encontrar genótipos menos preferidos pelo pulgão preto (Aphis craccivora) para infestação e colonização. Em abril e outubro de 2009, foram semeados 20 genótipos de porte prostrado e após a germinação verificouse o número de fêmeas e colônias de pulgão presentes e aos 30 dias avaliouse a porcentagem de plantas infestadas. No experimento conduzido em abril e maio, verificouse que todos os genótipos de feijãocaupi foram colonizados por A. craccivora. Porém nos genótipos MNC99537F142 e BRS Paraguassu foram observadas as menores percentagens de colônias. Em maio encontrouse as menores percentagens nos genótipos MNC99537F142, MNC01631F205 e BRS Paraguassu, com 6,3, 5,7 e 6,3% de plantas infestadas, respectivamente. Dentre os genótipos estudados, concluise que MNC99537F142, MNC01631F205 e BRS Paraguassu, podem ser melhores estudados, visando à seleção de materiais resistentes ao pulgão preto.

Cowpea (Vigna unguiculata (L.) Walp.) is an important food source. However, there is a lack of studies on this crop in Midwestern Brazil. Experiments were conducted in field conditions in Aquidauana, Mato Grosso do Sul, aiming to find genotypes less preferred by black aphid (Aphis craccivora (Koch.)). In April and October 2009, 20 prostrate genotypes were sown, and after germination the number of females and colonies were counted. At day 30, the percentage of infested plants was evaluated. In the experiment carried out in April and May, all genotypes were colonized by A. craccivora. However, the genotypes MNC99537F142 and BRS Paraguassu showed the smallest numbers of colonies. In May, the lowest percentages were found in the genotypes MNC99537F142, MNC01631F205 and BRS Paraguassu, with 6.3, 5.7 and 6.3 % of infested plants, respectively. Among the studied genotypes, MNC99537F142, MNC01631F205 and BRS Paraguassu should be further investigated for the selection of materials resistant to black aphids.
