Rearing of <I>Micraspis discolor</I> (Fabricius) on Artificial Food Sources
Main Article Content
Abstract
The objective of this study was to find out the suitable artificial foods for mass rearing Micraspis discolor (Fabricius) in laboratory. The completely randomized design with 30 replications and 5 treatments composed of honeycomb, honeybee pollen, honeybee brood, egg yolk and multivitamins was performed. The complete development of M. discolor was found when fed on only honeycomb and honeybee brood with the total development period from egg to adult at 36.25 and 37.00 days, respectively, longer than those fed on Aphis craccivora (Koch) which was only 13.47 days. The partial ecological life table showed that the highest mortality of M. discolor fed on honeycomb was found in the egg stage and first instar larva, meanwhile, the highest mortality of those fed on honeybee brood and A. craccivora was found in the pre-pupa and pupa stage. The survivorship curve of M. discolor fed on honeycomb, honeybee brood and A. craccivora was closely related to type III, I and I, respectively (P ≥ 0.05).
