THE GROWTH AND DEVELOPMENT OF Corcyra cephalonica (STAINTON)ud(LEPIDOPTERA: PYRALIDAE) REARED ON LOCAL FEED: QUALITYudCONTROL OF FACTITIOUS HOST

摘要

Laboratory experiments were conducted to evaluate growth and development of C. cephalonica reared on local feed. The product of linear dimensions and larval weight wasudtaken as the Numerical Index for Growth (NIG). The development parameters of pupae and adult measured were the length and weight of pupae, survival emerging adults, and her fecundity. The highest NIG (1945.83) was produced by larvae reared on the combination of corn meal and rice bran, but not significant than those (1581.31) reared on combination of chicken feed and corn meal. The highest weight occurred on pupae reared on diet containing chicken feed and corn meal (69.64 mg). The highest adult survival was found on chicken feed (56.03%), but significant different from of chicken feed and corn meal (46.37%). Female fecundity on chicken feed and corn meal were the highest (433.81 eggs/female). Thus, the most suitable media for growth and development of C. cephalonica was the combination of chicken feed and corn meal.
