ANWAR MOHAMED, ABEDELSALAM et al. Effect of larval nutrition on the development and mortality of Galleria mellonella (Lepidoptera: Pyralidae). Rev. Colomb. Entomol. [online]. 2014, vol.40, n.1, pp.49-54. ISSN 0120-0488.

The greater wax moth, Galleria mellonella, is an important pest of beekeeping industry. The effects of five natural diet materials on the developmental biology and mortality of all life stages of the greater wax moth were investigated in a laboratory trial. Effect of all five natural diets on the developmental biology and mortality varied significantly. New wax comb (NW) was found to be the poorest larval diet inducing prolonged immature stage duration, shortening adult moth longevity, decreasing egg productivity, retarding oviposition, prolonging the entire life-cycle duration and causing significantly higher overall life stage mortality. In contrast, feeding larvae on diets of old wax comb (OW), old wax comb containing 10% w/w added pollen (OWP), new wax comb containing 10% w/w added pollen (NWP), and bee-collected pollen (BP), positively affected the development and vitality of all life stages. The significance of these results with respect to the control measures are proposed and discussed.
