португальский. The objective of this study was to evaluate the biological parameters and the preference of Artemisia tridentata Nutt (Asteraceae) industrial pollen grains and beer yeast by Ch. externa adults for a more suitable diet for laboratory rearing. To conduct the experiment, 105 adults of newly emerged Ch. externa were used. They were placed in PVC cages (10.0 cm high x 10.0 cm in diameter), closed with PVC plastic film, each cage contained two females and one male (2: 1), and each cage was placed on a diet, being they are: Artemisia pollen (A. tridentata), artemisia + honey pollen (mixed), beer yeast, beer yeast + honey (mixed), water, honey, artemisia pollen + honey (separated). The diets 2 (artemisia pollen + mixed honey), 3 (brewer's yeast) and 4 (brewer's yeast + mixed honey) were shown to be statistically good diets at 5% confidence, according to the results analyzed for the parameters fecundity, oviposition, oviposition, mean number of eggs/day and viability of eggs. As the other diets 1 (artemisia pollen), 5 (water), 6 (honey) and 7 (artemisia pollen + separated honey) did not obtain statistically results, because they had means zero or close to zero, so these treatments are not feasible for a rearing of Ch. externa in the laboratory.
