Cassava is an essential tuber crop used to produce food, feed, and beverages. Whitefly pests, including Aleurothrixus aepim (Goeldi, 1886) (Hemiptera: Aleyrodidae), significantly affect cassava-based agroecosystems. Plant odours have been described as potential pest management tools, and the cassava clone M Ecuador 72 has been used by breeders as an essential source of resistance. In this study, we analysed and compared the volatile compounds released by this resistant clone and a susceptible genotype, BRS Jari. Constitutive odours were collected from young plants and analysed using gas chromatography?mass spectrometry combined with chemometric tools. The resistant genotype released numerous compounds with previously described biological activity and substantial amounts of the monoterpene (E)-β-ocimene. Whiteflies showed non-preferential behaviour when exposed to volatiles from the resistant genotype but not the susceptible genotype. Furthermore, pure ocimene caused non-preferential behaviour in whiteflies, indicating a role for this compound in repellence. This report provides an example of the intraspecific variation in odour emissions from cassava plants alongside information on odorants that repel whiteflies; these data can be used to devise whitefly management strategies. A better understanding of the genetic variability in cassava odour constituents and emissions under field conditions may accelerate the development of more resistant cassava varieties. |

Genetic characterization is an essential issue in the conservation and breeding programs of any country. In these work we report the use of RAPD markers in population genetic study of three breeds of different species that are in Brazilian genetic conservation program. The objective was to analyze the genetic similarity of individuals of those populations breeds in order to contribute to ex situ and in situ conservation. The selection of animals with least genetic similarity can help to conserve the maximum variability within a population, and can even optimize the choice of breeders for ex situ conservation programs. These studies were carried out in the Animal Genetics Laboratory (AGL) at Embrapa's Center for Genetic Resources and Biotechnology (CENARGEN). The native populations studied include: the Pantaneiro horse (in situ conservation nuclei), the bovine Crioulo Lageano (in situ conservation nuclei) and the Moxoto goat (five populations of these breed distributed in Northeast states). Using RAPD markers, obtained for each specie, we generated a Jaccard coefficient similarity matrix by NTSYS-pc v. 2.0 program. By the comparison between pairs of individuals we could chose those that were more similar between itself and those that were more distant. Using those matrix we suggested three kinds of procedure that could be used for helping the conservation of those breeds: the choice of the males to be semen donators - those less similar - avoiding duplication of samples (animals with high genetic similarity); the indication of preferential crossings aiming at the maintenance of the maximum genetic variability and the indication of animals for discarding - those that had high similarity - the breeder chose one of them for the discard. This kind of analysis could be done between two populations of the same breed in order to contribute to the genetic sample exchange between different nuclei. We must remember that these recommendations are based exclusively on genetic data and must lead in account the phenotypic characteristics of each animal, not having however to be considered separately.
