Influence of a diet containing tobacco on the biology of Ephestia kuehniella (Lepidoptera: Pyralidae) and its parasitoid Habrobracon hebetor (Hymenoptera: Braconidae)
Host diet often influences its biological parameters and the success of their parasitoids, both in mass rearing, field research and parasitism in applied biological control programs. Habrobracon hebetor (Say, 1836) (Hymenoptera: Braconidae) is an important biological control agent of the flour moth...

| description | Host diet often influences its biological parameters and the success of their parasitoids, both in mass rearing, field research and parasitism in applied biological control programs. Habrobracon hebetor (Say, 1836) (Hymenoptera: Braconidae) is an important biological control agent of the flour moth Ephestia kuehniella (Zeller, 1879) (Lepidoptera: Pyralidae), which infests tobacco, grain and other products in storage. This study aimed to evaluate the effect of different proportions of tobacco in artificial diets on the biological parameters of the host E. kuehniella and its parasitoid H. hebetor. Four classes of Virginia tobacco with different sugar and nicotine concentrations were added to flour diets for moths in different percentages (5, 10 and 15%).The experimental design was completely randomized in a 3 × 4 factorial scheme (percentage of dietary tobacco × class of tobacco). In the parasitoid bioassays, hosts fed only with 5% tobacco were used. For E. kuehniella, the development time (egg-adult), viability of immature stages, sex ratio, fecundity, egg viability and longevity were measured. For H. hebetor, percentage parasitism, offspring sex ratio, number of paralyzed and parasitized larvae, egg-adult viability and parasitism preference were measured. Tobacco classes and percentages added to the diet influenced the development time and viability of E. kuehniella. The 5% host diet did not influence the different biological parameters and behaviour of H. hebetor. For mass rearing of H. hebetor, it is unnecessary to add tobacco to the artificial diet in order to improve parasitoid performance. |
