Artificial diet for the production of achroia grisella(pyralidae)(fabricius,1794)

Abstract

The objective of the research is toformulate an artificial diet that allows to massively raisingAchroia grysellaas intermediary host for the mass production of biological controllers. Material from apiaries was used to select larvae and postures for the experiment were used from the obtaining of adults. The ingredients used were: corn flour, soy flour, blond sugar, brewer's yeast, glycerin, Wesson salts, vitamin mixand distilledwater. Three types of diets were formulated, with different proportions, which were distributed in 1Lglass bottles of capacity, at a rate of 250g of diet; 100 eggs were placed and since day 15 the diet was evaluated to see the larval stages that had grown and developed. Diets were evaluated by the number of stage V and VI larvae. The diets that obtain 80% or more of these types of stages were the one that to achieve the objectives of this investigation.Observations indicated that diet B was the one that offered more than 80% of larvae of stages V and VI, which fulfilled the proposed objective.The present study establishes that from the three formulations, the diet B is the one that allows recoveringmore than 80%of larvae in stages V and VI that can be used as intermediary hosts in replacement of the definitive hosts, for massive production of some biological controllers.
