Morphometric Analysis of Populations of Centris aenea Lepeletier (Hymenoptera: Apidae) from Northeastern Brazil
Provedor de dados: 82
Autores: Ferreira,VS; Aguiar,CML; Costa,MA; Silva,JG.
Centris aenea Lepeletier is a solitary bee that has raised interest in management to pollinate crops, such as acerola, Malpighia emarginata. This study investigated the level of morphometric variability among populations of C. aenea from Northeastern Brazil. Traditional and geometric morphometric analyses were used. Head length, leg length, wing length, and wing shape were measured in samples (5-10 females) from eight localities. We did not find statistically significant differences among the populations (P &gt; 0.01). The partial wing warps were similar in the populations and indicated that the bees were not morphometrically different. Our results suggest that C. aenea shows low population morphometric variability and highlight the need for further...

A morphometric and molecular study of Anastrepha pickeli Lima (Diptera: Tephritidae)
Provedor de dados: 82
Autores: Bomfim,ZV; Lima,KM; Silva,JG; Costa,MA; Zucchi,RA.
This study investigated the level of morphometric and genetic variability among populations of Anastrepha pickeli Lima from several localities in Brazil, one locality in Bolivia and one in Paraguay. Traditional and geometric morphometric analyses were used, as well as sequencing of a fragment of the cytochrome oxidase gene (COI). Six variables were measured from the aculeus for traditional morphometric analysis and 14 landmarks from the right wing were used for geometric analysis, using 10 specimes/population. The aculeus tip length, aculeus width at the end of the cloaca opening, and the serrate part length contributed with 62.7% for grouping. According to the results from traditional morphometry, there was no significant difference, but the multivariate...
