| A mosca-minadora é a principal praga do meloeiro no Brasil e motivo para o uso abusivo de inseticidas. Considerando que a implantação de cultivares resistentes se apresenta como uma alternativa promissora, este trabalho avaliou o efeito de diferentes linhagens de meloeiro sobre a biologia (número de minas, sobrevivência larval e pupal) da mosca-minadora Liriomyza sativae, com o objetivo de encontrar, entre os materiais testados, linhagens que sejam menos danificadas por L. sativae . Avaliaram-se 17 linhagens de meloeiro, provenientes do Programa de Melhoramento de Melão da Embrapa, incluindo o híbrido comercial ?Goldex? como testemunha suscetível. No teste com chance de escolha, não foram constatadas diferenças significativas entre as linhagens em relação... |

| De junho/92 a maio/94, capturas de mutucas foram realizadas mensalmente em eqüino e utilizando armadilhas do tipo ?canopy?, na fazenda Nhumirim, subregião da Nhecolândia, Pantanal sul-mato-grossense. Capturas no eqüino foram realizadas do crepúsculo matutino ao vespertino, com o auxílio de redes entomológicas, em ambientes de campo e cerradão (1 dia/ambiente/mês), durante o primeiro ano do estudo. Capturas com armadilhas foram realizadas nos mesmos ambientes (10 dias/ambiente/mês), por dois anos. Foram capturadas 6.274 mutucas ao longo do estudo, pertencentes a 25 espécies, 13 gêneros e 3 subfamílias. A espécies mais abundantes foram Tabanus importunus (44,04%), Tabanus occidentalis (15,95%), Tabanus claripennis (9,98%) e Lepiselaga crassipes (7,60%).... |

| Many insects host facultative, bacterial symbionts that confer conditional fitness benefits to their hosts. Hamiltonella defensa is a common facultative symbiont of aphids that provides protection against parasitoid wasps. Protection levels vary among strains of H. defensa that are also differentially infected by bacteriophages named APSEs. However, little is known about trait variation among strains because only one isolate has been fully sequenced. Generating complete genomes for facultative symbionts is hindered by relatively large genome sizes but low abundances in hosts like aphids that are very small. Here, we took advantage of methods for culturing H. defensa outside of aphids to generate complete genomes and transcriptome data for four strains of... |

| In several insects, sex-pheromones are essential for reproduction and reproductive isolation. Pheromones generally elicit stereotyped behaviors. In moths, these are attraction to conspecific sex-pheromone sources and deterrence for heterospecific sex-pheromone. Contrasting with these innate behaviors, some results in social insects point toward effects of non-sex-pheromones on perception and learning. We report the effects of sex-pheromone pre-exposure on gustatory perception and habituation (a non-associative learning) in male Agrotis ipsilon moths, a non-social insect. We also studied the effect of Z5-decenyl acetate (Z5), a compound of the sex-pheromone of the related species Agrotis segetum. We hypothesized that conspecific sex-pheromone and Z5 would... |

| Heritable symbionts are common in terrestrial arthropods and often provide beneficial services to hosts. Unlike obligate, nutritional symbionts that largely persist under strict host control within specialized host cells, heritable facultative symbionts exhibit large variation in within-host lifestyles and services rendered with many retaining the capacity to transition among roles. One enigmatic symbiont, Candidatus Fukatsuia symbiotica, frequently infects aphids with reported roles ranging from pathogen, defensive symbiont, mutualism exploiter, and nutritional co-obligate symbiont. Here, we used an in vitro culture-assisted protocol to sequence the genome of a facultative strain of Fukatsuia from pea aphids (Acyrthosiphon pisum). Phylogenetic and genomic... |

| The sugarcane borer, Diatraea saccharalis Fabricius, has great economical interest as it affects the culture and industrial use of the sugarcane. However, there are few studies concerning the internal morphology of this insect. This work aims to study morphometrically the midgut and the epithelium along their lenght, trying to characterize different regions. Midgut of last instar larvae was divided in three regions: anterior, middle and posterior, and the fragments were processed for light microscopic observation. Histological sections were analyzed in a computerized system concerning the length, width and area of the epithelium, their cells, and the midgut lumen. The obtained data were statistically analyzed by the Kruskal-Wallis test and by multivariate... |
