Special attention should be given to forest plantings in order to minimize the probability of exotic pest introduction and, consequently, of production losses. The objective of this review was to present, under a historic perspective, the main exotic insects that harm the Brazilian forest sector. Therefore, to better describe the phytosanitary context of introduced forest pests in Brazil, the main information regarding these insects was gathered here. Introduced species and species with a risk of introduction were listed. The following species were registered: 12exotic introduced species related to eucalyptus, non?quarantine; 9 species related to pine, one quarantine; and 1 species related to teak, quarantine. Overall, the core problems for 57 pest species were addressed, followed by projections on current risks and priorities. Biological control programs and their respective agents were also mentioned. For eucalyptus plantations, the species belonging to the genera Ophelimus and Leptocybe are priorities and should be emphasized. Regarding pine species, the main current concerns are Bursaphelenchus xylophilus (transmitted by species of Monochamus), Rhyacionia frustrana, and Dendroctonus frontalis. Better risk management requires reinforcement of phytosanitary inspections and constant refinement of contingency plans, whose actions include monitoring by visual sampling, employment of sentinel plants, and preventive breeding programs aiming at pest resistance. |

Estimates of genetic diversity based on molecular and morphological data are common in the literature; however, they do not take the most agronomically important traits into consideration. Use of these estimates for recommending parent lines has not had much practical success because the populations thus generated generally exhibit wide variability, but medium to low means for the target trait. A total of 17 common bean cultivars were evaluated in 31 trials conducted in 2008, 2009, and 2010 in the rainy, dry, and winter crop seasons in Brazil. Twelve traits of agronomic importance were evaluated. Analysis of variance were performed on the data and the means were used to estimate the Euclidean distances. In addition, leaves were collected, DNA extracted, and amplification reactions were performed with 33 microsatellite markers to obtain the genetic distances based on complement of the weighted similarity indexes. The genotypes were clustered by the Tocher method. Both forms of estimation of genetic distance showed diversity among the cultivars. The Pearson correlation estimate between the agronomic and molecular genetic distance matrices was significant (0.32), but of low magnitude, which indicates that the distances estimated by the two sets of data supply different information. Coincidence between the clusters was 53%, confirming that this information can truly be considered complementary. The phenotypic mean values for grain yield, the divergence estimates, and the clusters formed by phenotypic and molecular data indicated some crosses with greater probability of obtaining higher yielding lines: BRSMG Majestoso 9 CNFC 10431, BRS Estilo 9 BRS Nota´vel, and BRS Estilo 9 BRS Pontal.
