Última Polimorfismo enzimático em populações de Melipona quadrifasciata anthidioides Lepeletier (Hymenoptera, Apidae, Meliponinae) Zoologia Aidar,Davi S.; Pagotto,Rubiane C.; Contel,Eucleia P.B.. 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...

Ano: 2001 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0101-81752001000200018 Número de alelos XO em uma população de Melipona quadrifasciata anthidioides Lepeletier (Hymenoptera, Apidae, Meliponinae) Zoologia Aidar,Davi S.; Kerr,Warwick E.. The number of xo alleles of a population of stingless bees can be estimated by observing the male proportion of the first brood comb produced by a new queen (about 40 Fl bees) and the total number of colonies. A proportion of 50% diploid males indicates insemination of the queen by a single male with some xo sex allele: 25% diploid male would indicate insemination by two males (one with some xo as the queen and another with different one). Diploidy was confirmed by cytology of the testis. The original population (78 colonies) of Ribeirão Preto, State S. Paulo, Brazil, had 8 xo sex alleles. From this population, 10 colonies were orphaned and taken to the Serra do Mar (Sea Mountains) at Espirito Santo State (1200 km far) in order that the virgin queen of...
