“…Elongation factor-1␣ (EF-1␣) has been widely used to infer phylogenies (e.g., Cho et al, 1995;Belshaw and Quicke, 1997;Friedlander et al, 1998). It is one of the most abundant proteins in eukaryotic cells, in which it catalyzes the binding of charged tRNAs to the ribosome during translation.…”

“…Protocolo 5 -modifi cado a partir de Belshaw & Quicke (1997): Insetos inteiros foram macerados em 700 l de NaCl 5 M. Em seguida adicionou-se 1 l de proteinase K (20 mg ml -1 ) e incubou-se as amostras por 18h a 37ºC. Posteriormente, estas foram centrifugadas por 7 min a 12484 g e o pellet foi lavado com 500 l de acetato de sódio 0,2 M em etanol 76%.…”

-The work was carried out to test DNA extraction protocols and to characterize populations of Tibraca limbativentris Stål, an important rice insect-pest. Insects were collected in Joinville, Rio do Oeste and Turvo, in Santa Catarina State, and Agudo, Uruguaiana, Pelotas and Palmares do Sul, in Rio Grande do Sul State, and six literature-referenced protocols, besides a new one, were tested. DNA from ten individuals of each population was extracted using the best protocol and RAPD reactions were carried out with ten initiators. The new protocol showed the best results and was used in the PCR reactions, that generated 151 polymorphic bands, allowing to access genetic differences among all the populations; no individuals from one population were clustered with individuals from another. The largest intrapopulacional similarity was found in Uruguaiana (22%), and the smallest in Palmares do Sul (50%), which was also the most divergent population in relation to the others. The Gst was 0.5215, and the Nm was 0.4588; these values refl ect the low similarity between the populations. The smallest genic fl ow was obtained when Palmares do Sul and Pelotas were included in the comparisons, in accordance with the largest divergence of these two populations in relation to the others. There was no signifi cant relation between geographic distance and genetic similarity, which can refl ect unknown model of dispersion of T. limbativentris. New studies exploring the species dispersion strategies may help to understand the insect distribution and to unveil the main factors linked to the genetic variability within and between populations.KEY WORDS: Insecta, rice stem bug, irrigated rice, molecular marker RESUMO -O trabalho objetivou testar protocolos de extração de DNA e caracterizar populações de Tibraca limbativentris, Stål, importante inseto-praga do arroz. Os insetos foram coletados em Joinville, Rio do Oeste e Turvo, em Santa Catarina, e Agudo, Uruguaiana, Pelotas e Palmares do Sul, no Rio Grande do Sul. Testaram-se seis protocolos de extração de DNA citados na literatura, e um novo protocolo adequado à espécie em questão. DNA de dez indivíduos de cada população foi extraído usando o melhor protocolo e reações de RAPD foram realizadas com dez iniciadores. O novo protocolo mostrou os melhores resultados e foi utilizado nas reações de PCR, que geraram 151 bandas polimórfi cas, permitindo acessar diferenças genéticas entre todas as populações; não ocorreram indivíduos de uma população agrupados com os de outra. A maior similaridade intrapopulacional foi encontrada em Uruguaiana (22%), e a menor em Palmares do Sul (50%), também a população mais divergente das demais. O valor Gst foi 0,5215, e de Nm 0,4588; esses valores refl etem a pouca similaridade entre as populações. O menor Nm foi apresentado quando Palmares do Sul e Pelotas foram incluídos nas comparações, em consonância com a maior divergência apresentada por essas populações em relação às outras. Não se observou relação entre a distância geográfi ca e a similaridade ...

In a previous study, we observed no spatial genetic structure in Mexican populations of the parasitoids Chelonus insularis Cresson (Hymenoptera: Braconidae) and Campoletis sonorensis Cameron (Hymenoptera: Ichneumonidae) by using microsatellite markers. In the current study, we investigated whether for these important parasitoids of the fall armyworm (Lepidoptera: Noctuidae) there is any genetic structure at a larger scale. Insects of both species were collected across the American continent and their phylogeography was investigated using both nuclear and mitochondrial markers. Our results suggest an ancient northÐsouth migration of C. insularis, whereas no clear pattern could be determined for C. sonorensis. Nonetheless, the resulting topology indicated the existence of a cryptic taxon within this later species: a few Canadian specimens determined as C. sonorensis branch outside a clade composed of the Argentinean Chelonus grioti Blanchard, the Brazilian Chelonus flavicincta Ashmead, and the rest of the C. sonorensis individuals. The individuals revealing the cryptic taxon were collected from Trichoplusia ni (Hü bner) (Lepidoptera: Noctuidae) on tomato (Lycopersicon spp.) and may represent a biotype that has adapted to the early season phenology of its host. Overall, the loosely deÞned spatial genetic structure previously shown at a local Þne scale also was found at the larger scale, for both species. Dispersal of these insects may be partly driven by wind as suggested by genetic similarities between individuals coming from very distant locations.
