The influence of some honeybee products as a diet substitute on the different stages of Coccinella undecimpunctata L. in Egypt

Several natural diets of honeybee products were tested for rearing Coccinella undecimpunctata L. under laboratory conditions. Two groups of tested adult and larval insect have been fed on the tested diets, the first group were fed on the tested honey bee products diets without adding aphids, while the second group fed on the same honeybee products with aphids added. The oviposition period in the first group was significantly shorter than control. The tested diets supplied with royal jelly + aphid and/or pollen grains + aphid caused the longest oviposition period. Diets of aphid alone and bee honey with aphid recorded the shortest oviposition period. Fecundity of ladybird was the highest in the tested diets with aphids than diets without aphid and/or aphid diet alone. The durations of larval and pupal stages were significantly different when compared with the diets with or without aphid and/or aphid diet alone. Further results indicated that the diets of royal jelly caused the shortest duration in larval and pupal stages.
