The mite Varroa destructor is one of the most studied parasites in apiculture, and its genotype variation is a key factor for the severity of infestation in bee colonies. Here we report the genetic and reproductive profile of mites from 14 Brazilian states with different geographic and climatic conditions. We performed PCR to amplify a fragment of the COI gene and differentiate the haplotypes using restriction enzymes. The K haplotype was widely prevalent in the studied sites, while the J haplotype was found only in four municipalities. We also observed both haplotypes (J and K) coexisting in the same colony, a fact unprecedented in Brazil. Infestation levels were low (0.33 to 15.3%). The reproductive potential showed wide variation (0 to 1.5), indicating that even with the massive presence of K haplotype, environmental and biotic factors related to Africanized honeybees may be responsible for maintaining the mite under low levels in Brazil. |

Potassium (K) is one of the most important nutrients limiting yield of common bean in South America. Use of K-efficient crop genotypes along with K fertilizer may be a viable strategy to improve yield and reduce cost of production. A greenhouse experiment was conducted to evaluate K-use efficiency of 10 promising genotypes of common bean (Phaseolus vulgaris L.). The genotypes were grown on an Oxisol at 0 mg K kg-1 (low K) and 200 mg K kg-1 (high K) of soil. Shoot dry weight, grain yield, number of pods, number of grains, 100-grain weight, grain harvest index, and K harvest index were significantly (P < 0.01) affected by level of K as well as genotype, except for the number of pods by genotype. Significant genotypic differences in K-use efficiency were found. On the basis of K-use efficiency (mg grain weight/mg K accumulated in shoot and grain), genotypes were classified as efficient and responsive (ER), efficient and nonresponsive (ENR), nonefficient and responsive (NER), and non-efficient and non-responsive (NENR). Only genotype Diamante Negro was only classified as ER, and genotypes Carioca, Pérola, Rosinha G-2, and Xamego were classified as ENR. Genotypes LM93300166 and LM93300176 were in the group NER, and in the NENR group were genotypes Iraí, Jalo Precoce, and Novo Jalo. From a practical point of view, genotypes which produce high grain yield at a low level of K and respond well to added K are the most desirable because they are able to express their high yield potential in a wide range of K availability.
