Spraying the infective stage of the nematode Neoaplectana carpocapsae Weiser directly on frames containing Apis mellifera L. resulted in limited mortality of worker bees and no mortality to the brood. Nematode mortality of adult bees was found only d

Twenty-five adult female Plodia interpunctella infected with Nosema plodiae laid 856 eggs in laboratory tests; 12.5% of the eggs were infected transovarially. The highest level of transmission by an individual female was 14 infected eggs of 27 laid (
