抄録

Experiments on the improvement of mass rearing technique of the melon fly were carried out on following points: 1. Effects of two brands of wheat shorts, i. e. No.1 Canadian Wheat and Western White, used as a major part of larval medium, on the yield of pupae were investigated. A reasonable rate of pupal recovery (more than 60% of eggs) was obtained using the media containing the former brand in a wide range of pH (3.8-5.0), but when using the later brand, the rate of recovery declined in pH range less than 4. 6. 2. When the AMBER BYF-Series 100, a cheap protein-hydrolyzate, was used in place of Phytonyeast extract, which has been used earlier, as a nutrient in adult diet the yield of egg and mortality of adults were comparable to those from the diet including the later. 3. A mechanical sifter was devised to sieve pupae from saw-dust. No harmful efeffect on the survival rate of pupae was detected when the sifter was used in 273 rounds of 1 inch-strokes per minutes.

ウリミバエの不妊化用蛹を安定的に供給する大量飼育法確立のため，1）幼虫培地用フスマの品質問題，2）成虫飼育料の低廉化，3）作業省力化のための動力篩の利用について検討した．　1．No.1 Canadian Wheat, Westean Whiteの2種のフスマのうち，前者は飼育できるpHの範囲が5.0～3.8と広く，後者は4.8～5.0と狭い．この結果大量飼育用には前者を採用した．　2．ANBER BYF-Series 1OOは従来までのフィトン＋イーストエキストラクトに比較し，廉価で成虫飼料として適していることが判った．　3．動力篩は，振幅1インチ，毎分273回転で篩っても，1分前後ならば蛹の死亡，奇形虫の発生に影響なく，6ℓの蛹―オガクズ混合物を1分程度で篩別できる．
