| The dark coloration of insects eyes is attributed to the accumulation of the brown pigment insectorubin, a mixture of ommochromes, xanthommatin and several ommins, biosynthesized from tryptophan. When any of the events in the synthesis chain is interrupted, formation and accumulation of pigments other than insectorubin occurs, and a new eye color will appear. The aim of the present work is to evaluate the longevity of worker honey bees Apis mellifera, homozygous and heterozygous for the mutant alleles cream (cr), snow-laranja (s la) and brick (bk). Eye pigmentation and average longetivity of bees are very closely related. Mutant bees carrying lighter eye pigmentation are unable to return to the hive; there is, therefore, a close association between the eye... |

| In this work, we used the Minimum Inhibitory Concentration (MIC) technique to evaluate the antibacterial potential of the apitoxin produced by Apis mellifera bees against the causative agents of tooth decay. Apitoxin was assayed in naturaand in the commercially available form. The antibacterial actions of the main components of this apitoxin, phospholipase A2, and melittin were also assessed, alone and in combination. The following bacteria were tested: Streptococcus salivarius, S. sobrinus, S. mutans, S. mitis, S. sanguinis, Lactobacillus casei, and Enterococcus faecalis. The MIC results obtained for the commercially available apitoxin and for the apitoxin in natura were close and lay between 20 and 40µg / mL, which indicated good antibacterial activity.... |
