| Abstract |
As of this moment, a major component in the artificial larval medium of olive fly is chromatography cellulose powder. A material of very high cost and difficult to find in the market today. Cellulose secures proper texture for larval survival, feeding activity and growth. The present study attempted to replace cellulose by material(s) of relatively low cost and easily available. A variety of materials were used as possible substitutes of cellulose powder, with zero or poor results compared to control treatment regarding the yield from egg to pupa. Nevertheless, encouraging results were achieved when cellulose was replaced by sponge towel vetex (+75% the preservatives of standard medium), and filter paper (+75% preservatives). The high cost of filter paper should be noted. Alternative treatments were investigated as well, to ensure substantial reduction of cellulose and rearing cost. These included the methodologies of Starter-Finisher and Recycling. The results obtained when the Starter-Finisher methodology was applied, with the standard diet as Starter, and vetex (+75% preservatives) or filter paper (+75% preservatives) as Finishers, were satisfactory, although of lower medium productivity compared to control. Particularly positive results were obtained with Recycling, i.e. complete reuse of larval medium for larval rearing, or reuse of larval medium as finisher. In both cases best results were obtained when water was added and thorough mixing was applied to ensure proper medium texture. Further research is needed in order to develop an effective low cost medium without cellulose powder as basic texture material. Also further research is needed to standardize larval medium Recycling and Starter-Finisher methodologies for the olive fruit fly mass rearing.
