Studies On Optimizing And Selecting Artificial Diets For Bactrocera Dorsalis (Henel)

Experiments of orthogonal design were uesd to select the optimum artificial diets for B.dorsaiis.A kind of rational prescription of artificial diet of laval B.dorsalis was found in this experiment.And biology speciality was introduced in this paper. Now,results of experiments as follows:1. Prescription of artificial diet of imago B.dorsalis was designed and optimized. Experiment showed that alternative use of prescription A and B was successful to feed imago B.dorsalis, which prescription A is proportion 3:1:20 of Sucrose ,Beer yeast and water supply and prescription B was 5% honey. After feeding by this kind of prescription, imago life-span, quantity on oviposition and rate of hatch of imago B.dorsalis was improved evidently.2. Three experiments of orthogonal design were uesd to select the optimum artificial diets for B.dorsalis. Firstly, Ethyl butanoate and Ammonium bicarbonate were selected from four kinds of material attraction ,which were Benzyl acetic acid, Ethyl benzoate, Ethyl butanoate and Ammonium bicarbonate . The experiment showed that Ethyl butanoate and Ammonium bicarbonate were favourable eating-lured material to B.dorsalis. Secondly, as a kind of best oviposition-lured material to B.dorsalis, Ethyl butanoate was selected from five kinds of material attraction which were syrup, Citric acid, Benzonic acid, Ethyl acetate and Ethyl butanoate. Thirdly, Experiments of orthogonal design selcted and optimized quantity and specific value of four kinds of basic factors. At the same time, interaction among the basis was analyzed and an optimum artificial diets for B.dorsalis was found lastly.3.The breeding method to B.dorsalis and it's biology speciality was introduced in this part. At one time, the optimum prescription and it's confect method of artificial diets for laval B.dorsalis was introduced. All kinds of instruments to breed B.dorsalis were selected and different temperature, humidity and illumination were tested. Having continuously Reared 5 generation, the hatch rate ,laval livability,pupation rate,mean pupal weight.pupal reached 75.0%, 84.1%,15.22mg, 94.7%, 95.7% leave each other.
