Artificial Diet for Rearing the Annona Fruit Borer Cerconota anonella Sepp, 1830 (Lepidoptera: Oecophoridae)
Published online by Cambridge University Press: 19 September 2011
Abstract
Cerconota anonella is the most important pest of the Annonaceae in the Neotropical region for larval damage, which can result in 60 to 100% losses in fruit production. However information on the pest's biology is scarce. This research compared different artificial diets for rearing C. anonella under laboratory conditions (25.0 ± 1.0 °C; 60 ± 5.0% RH and 14 h photophase). Five diets were compared: A (bean, soybean meal, wheatgerm, casein and yeast), B (maize flour, wheatgerm and yeast), C (wheatgerm and casein), D (wheatgerm and soybean) and E (wheatgerm and soybean). In diet E, the amount of wheatgerm was higher than that in dietD. The results indicated that diet E was the most suitable one for the development of C. anonella.
Résumé
L'objectif de ce travail est de comparer des milieux artificiels destinés à l'élevage de Cerconota anonella Sepp, 1830 en conditions de laboratoire (25,0 ± 1.0 °C; HR 60, 0 ± 5.0% et 14 h de photopériode). Cinq milieux artificiels ont été comparés: A (haricot, farine de soja, germe de blé, caséine et levure), B. (farine de maïs, germe de blé et levure), C. (germe de blé et caséine), D (germe de blé et soja) et E (germe de blé et soja). La quantité de germe de blé du milieu E est plus élevée que celle du milieu D. Les résultats montrent que le milieu E est le mieux adapté au développement de C. anonella.
