米蛾人工饲料配方筛选

为解决米蛾饲料匮乏和研究基础狭窄的现状,开展了米蛾的人工饲料配方筛选试验。进行了5种不同饲料配方对于米蛾生长以及产卵量的调查。配方E(70%玉米面+20%米糠+7%白砂糖+3%酵母)繁育的米蛾生长周期(35d)明显短于配方A(94%米糠+3%白砂糖+3%酵母)、B(97%米糠+3%白砂糖)、C(100%米糠)和D(70%玉米面+24%米糠+3%白砂糖+3%酵母),平均出蛾数量(4 969只)显著高于配方A、B、C和D;配方E饲喂的雌蛾、雄蛾平均质量分别为40.47和16.70mg,明显高于其它配方。配方E繁育米蛾的产卵量最高(503粒)。筛选出配方E最适合米蛾繁育。

Selection of the Artificial Diets of Corcyra cephalonice

In the light of prsent situation of poor in the diets of Corcyra cephalonice and limited in research foundation,screening the artificial diets of Corcyra cephalonice was carried out.The growth and fecundity of Corcyra cephalonice were studied on five artificial diets.There was shorter growth cycle (35 d) and higher total number of emergence (4 969 adults) for C.cephalonice on diet E(70% corn flour+20% rice bran+7% sugar+3% yeast) than on diets A(94% rice bran+3% sugar+3% yeast),B(97% rice bran+3% sugar),C(100% rice bran) and D(70% rice bran+24% rice bran+3% sugar+3% yeast),respectively.In addition,the bodyweight of female adults and male adults reared by diet E(40.47 and 16.70 mg) which was significantly higher than those by the other four diets.The female adults from diet E had the largest number of oviposition(503 eggs).Taken together,the best optimal was diets E.
