摘要/Abstract

摘要： 研究了家蝇Musca domestica幼虫中试生产中的种蝇产卵力。结果表明，以红糖、奶粉作为种蝇饲料时产卵力最高，在饲料中加入蔬菜汁有助于提高种蝇产卵力。在设置的种蝇密度范围内，种蝇密度中等时（5.973 头/m3），单蝇平均产卵力最大（9.68 粒/天）；种蝇密度越大，产卵力相对越稳定，每笼总产卵数越多。同日龄的成蝇群体开始产卵后，约4天进入产卵高峰期，此期持续3～5天；一周后，产卵力开始明显下降。产卵高峰期过后，人为处死当前种群，并使另一种群的产卵高峰期接续上，可将种蝇产卵力连续维持在较高水平，这是人工饲育条件下的重要特点。

Abstract: The effect of diet and density on the fecundity of adult houseflies in the pilot scale production of housefly larva was studiedA diet of brown sugar and milk powder was found to increase the fecundity of adult houseflies, and vegetable juice was found to be a helpful additiveThe fecundity was maximal （9.68 ovum/ind·d） at a moderate adult density（5.973 ind/m³）. The greater the adult density，the more stable the fecundity and the higher the total ovum number in the experimental enclosure. The peak of fecundity was reached about four days after oviposition began and was maintained for 3-5 days. A week later the fecundity had decreased markedly. After the oviposition peak had passed，the present population was killed，and another population already at the peak of oviposition was introduced. The fecundity was maintained continuously at a high level，which is an important aspect in artificial rearing
