Produção de Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) com a utilização de fubá de milho na dieta artificial
[Production of the mediterranean flour moth, Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae), on an artificial diet containing corn meal]
Neotropical Entomology 30 (1), 37-42
Abstract: To reduce the cost of obtaining Anagasta kuehniella (Zeller), which is an alternative host for mass production of Trichogramma galloi Zucchi, we tested the substitution of yellow corn meal in different proportions for whole wheat meal. We compared the standard diet (97.0% whole wheat, 3.0% yeast) with four experimental diets: corn meal (97.0%) and yeast (3.0%); corn meal (62.7%), whole wheat meal (34.3%) and yeast (3.0%); corn meal (48.5%), whole wheat meal (48.5%) and yeast (3.0%); corn meal (34.3%), whole wheat meal (62.7%) and yeast (3.0%). Rearing room was maintained at 25±1oC; 12h of photophase and 70±10% RH. The diets containing corn meal, whole wheat meal and yeast produced the best results, which were comparable to those found for the standard diet in all aspects investigated: egg viability and weight, fecundity, developmental time, survival of immature stages, and adult weight. Among the diets containing corn meal, the one with 48.5% of this ingredient promoted the best survival ratio of the immature stages. In addition, adult females originated from these immatures were more fecund than those from immatures which fed the diet containing corn meal and yeast only. But we did not find any significant difference with regard to the others factors investigated.

Com o intuito de reduzir o custo de produção de Anagasta kuehniella (Zeller), foram avaliadas características biológicas desse hospedeiro utilizado na criação de Trichogramma galloi Zucchi, quando na composição de sua dieta a farinha de trigo integral foi substituída total ou parcialmente pelo fubá de milho amarelo. O experimento, conduzido a 25±1oC, 12h de fotofase e 70±10% de UR, constou de cinco dietas: fubá de milho (97,0%) e levedura de cerveja (3,0%); fubá de milho (62,7%), farinha de trigo integral (34,3%) e levedura de cerveja (3,0%); fubá de milho (48,5%), farinha de trigo integral (48,5%) e levedura de cerveja (3,0%); fubá de milho (34,3%), farinha de trigo integral (62,7%) e levedura de cerveja (3,0%); farinha de trigo integral (97,0%) e levedura de cerveja (3,0%) (padrão). Foram avaliados a duração do ciclo e a sobrevivência dos estágios imaturos, o peso dos adultos, o número de ovos/fêmea/dia e a viabilidade e peso de 100 ovos. Com base nessas características, as dietas constituídas de fubá de milho, farinha de trigo integral e levedura de cerveja foram tão boas quanto a dieta padrão para a criação de A. kuehniella. Dentre as dietas contendo fubá de milho, aquela com 48,5% desse componente apresentou a melhor taxa de sobrevivência dos estágios imaturos. Além disso, os imaturos criados nessa dieta originaram fêmeas adultas mais fecundas do que aquelas obtidas na dieta constituída apenas de fubá e levedura. Não houve diferenças para os demais parâmetros investigados.
