@article{oai:kindai.repo.nii.ac.jp:00004793, author = {本藤, 智雄 and 香取, 郁夫 and 杉本, 毅}, issue = {39}, journal = {近畿大学農学部紀要, Memoirs of the Faculty of Agriculture of Kinki University}, month = {Mar}, note = {[Author abstract] We adopted Neochrysocharis formosa among the native eulophid wasps as the biological control agent against Liriomyza trifolii which is a serious pest of vegetables and ornaments, and designed the mass production process of N. formosa. Next, we made the ovipositting equipment and the gathering equipment for eclosed adults of hosts and parasitoids, tested thier performance, and evaluated suitable stage of parasitoids for packaging and method of strage. The collection rates of adults of host and parasitoid after oviposition wasn't high by either the horizontal-moving type or the vertical-moving type of ovipositting equipment. The collection rates of eclosed adults of host and parasitoid by the gatherring equipment were both high when their adults and pupae were released in the equipment. Adult longevity and reproduction of parasitoid were sharply decreased by 3 or 5 days of storage at 15 ℃ soon after eclosion. When leaves of kidney beans including pupae in them were stored for 5 days at 15 ℃ after drying them, the adult eclosion rate of parasitoids was higher than that when leaves were stored without drying them. The adult eclosion rate of parasitoid pupae was as high when stored at 5 ℃ for 3 or 5 days as when not stored at 5 ℃. Furthermore, for mass production process, the most suitable release density of host was estimated as 50 larvae or 5 pairs of adults per plant, and that of parasitoid as 10 adults per 50 host larvae.[著者抄録]花卉・蔬菜類の重要害虫であるマメハモグリバエに対する生物的防除資材として土着寄生蜂ハモグリミドリヒメコバチを採用し,マメハモグリバエを寄主,インゲンマメを寄主植物とする大量生産工程を設計した。次に,この大量生産工程において作業の省力化・効率化のために産卵装置および羽化成虫回収装置を試作し,その性能評価,ハチの剤型梱包・保蔵方法について検討した。横移動式産卵装置における産卵を終えた両種成虫の回収率(ハエ75.3%,ハチ66.4%),縦移動式産卵装置におけるハチの回収率(68.4%)はあまり高くなかった。羽化成虫回収装置の回収率は,装置内に成虫を放飼した場合(ハエ雌86.9%,雄82.4%,ハチ雌94.4%)または蛹を放飼した場合(ハエ81.7%,ハチ92.5%)ともに高かった。ハチの寿命や繁殖能力は,羽化直後に15℃で3日および5日間の保蔵期間をもうけると,大幅に低下した。ハチ蛹の羽化率は,蛹を含んだインゲンマメ葉を乾燥させて,5℃で5日間保蔵すると(94.4%),葉を乾燥させずに保蔵した場合(85.7%)と比べて高かった。また,ハチ蛹を5℃で3日保蔵した後の羽化率(95.3%)および5日間保蔵した後の羽化率(100%)は,5℃で保蔵しなかった場合(96.5%)と同様に高かった。なお,大量生産のための最適放飼密度は,ハエ幼虫の場合インゲンマメ1株あたり50匹で,そのためのハエ成虫の放飼密度は5対と推定できた。一方,ハチ成虫の最適放飼密度はハエ幼虫50匹あたり10匹と推定できた。, 記事区分:原著, application/pdf}, pages = {41--54}, title = {侵入害虫マメハモグリバエに対する生物的防除資材としての土着寄生蜂ハモグリミドリヒメコバチの大量増殖法の確立}, year = {2006}, yomi = {ホンドウ, トモオ and カンドリ, イクオ and スギモト, ツヨシ} }
