| Three methods of division of Melipona quadrifasciata Lep. colonies were evaluated: fisogastric queen naturally mated; orphans colonies, and queen mated in laboratory. Out of six colonies, five had grade 7 in 221 days, reaching 83,3% of success, in the 1st method. Out of four, 100% were formed using the 2nd method, in 221 days, and 71,4% out of seven colonies were formed with grade 7 in 195 days using the 3rd method. All colonies were treated with Syrup-A; the same management and same system of evaluation. Colonies obtained were described performance by the following mathematic models: Grade1 = 1.202 + 0.262 x reading; Grade2 = 1.474 + 0.250 x reading and Grade3 = 1.406 + 0.287 x reading. The 3rd method was the best considering time of the colonies... |

| Them aim scope of this study is to characterize the enzymatic polymorphism found in the Melipona quadrifasciata Lepeletier, 1936 populations from Ribeirão Preto, São Paulo and Espírito Santo, Brazil and its hybrids. Samples from each colony (about 52) were prepared for starch gel electrophoresis in order to investigate the genetic variation of the following enzimes: esterase (EST), isocitrate dehydrogenase (IDH), malic enzyme (ME), phosphoglucomutase (PGM), superoxide desmutase (SOD), α-glycerophosphate dehydrogenase (αPGD), malate dehydrogenase (MDH), leucine aminopeptidase (LAP), hexokinase (HK) and phosphoglucose isomerase (PGI). The analysis showed that LAP and HK did not show enzymatic activity and EST showed two alleles(est-sand and est-f) while all... |
