Qualidade de diferentes espécies de pulgões como hospedeiros do parasitóide Lysiphlebus testaceipes (Cresson) (Hymenoptera: Braconidae, Aphidiinae)

Use of Rubidium to Label Lysiphlebus testaceipes (Hymenoptera: Braconidae), a Parasitoid of Greenbugs (Homoptera: Aphididae), for Dispersal Studies

Interference of Field Evidence, Morphology, and DNA Analyses of Three Related Lysiphlebus Aphid Parasitoids (Hymenoptera: Braconidae: Aphidiinae)

This study provides evidence on integrating the morphological, field, and laboratory data, and application of the cytochrome oxidase subunit I (COI) barcoding gene to the three asexual or sexual Lysiphlebus spp., i.e., Lysiphlebus cardui (Marshall), Lysiphlebus confusus Tremblay and Eady and Lysiphlebus fabarum (Marshall) (Hymenoptera: Braconidae: Aphidiinae). New aphid- invasive plant associat...

An 18S rDNA-based molecular phylogeny of aphidiinae (Hymenoptera: braconidae).

We have obtained a molecular phylogeny of the subfamily Aphidiinae (Hymenoptera: Braconidae) by sequencing the 18S rDNA in 37 aphidiine taxa. Approximately 1857 nucleotides were sequenced in each species. Evolutionary relationships were established by comparing the results of maximum-parsimony, maximum-likelihood, and distance analyses. The most variable region of this gene, V4 (approx 403 nucl...

Novas estratégias comunicativas como fator de qualidade na interação de surdos em um sistema organizacional

Reading difficulties and interpreting textual information interferes with the quality of communicative interactions between pre-linguistic deaf and web environment. This article aims to present a study of eight pre-linguíticos deaf users interacting with a web form in order to verify if the use of new communication strategies helps to improves the interactions. Were observed two sessions of int...
