摘要:	自2002年5月至2003年11月，於農業試驗所所屬基因轉殖隔離試驗田之網室及田問進行抗輪點病毒(PRSV)基因轉殖木瓜對環境中昆蟲及蹣類之影響評估◦定期調查基因轉殖與傳統台農二號木瓜上的害蟲、天敵發生種類及主要害蟲（蹣）之族群密度消長，結果顯示隔離網室內栽培兩供試木瓜上的昆蟲及蹣類種類相同，包括粉蝨成蟲、葉蹣、捕植蹣及捕食性蜘蛛◦於隔離田栽培兩供試木瓜上的昆蟲及蹣類種類亦相同，包括：棉蚜(Aphis gossypii)有翅型成蟲、赤圓介殼蟲(Aonidiella inornata)、螺旋粉蝨(Aleurodicus dispersus)、紋白蝶(Pieris rape crucivora)之蛹及成蟲、斜紋夜蛾(Spodoptera litura)幼蟲、黃瓢蟲(Illeis koebelei)、小黑瓢蟲(Stethorus sp.)、神澤氏葉蹣(Tetranychus kanzawai)及卵形捕植蹣(Amblyseius ovalis)◦發生最為普遍的神澤氏葉蹣在網室內及隔離田栽植的基因轉殖與非基因轉殖木瓜上族群消長趨勢一致，同時每次調查網室內栽培之基因轉殖與非基因轉殖木瓜上之蹣卵及活動蹣數差異均不顯著◦以及根據收集之相關資料評估分析抗輪點病毒基因轉殖木瓜對其他非目標昆蟲，包括授粉昆蟲、保育類昆蟲、土壤昆蟲及鳥類等的影響評估結果，認為抗輪點病毒(PRSV)基因轉殖木瓜對於環境中昆蟲類、蹣類及鳥類產生不利影響之風險性極低◦ Evaluation of impacts of the transgenic (PRSV) resistant papaya to environmental insects and mites were conducted at the isolated net house and the isolated field at ARI from May 2002 to November 2003. Species of pest insects and natural enemies and population fluctuations of the main pests on papaya were surveyed. Species of insects and mites occurred on transgenic and control papayas were the same. These included aphis gossypii, Bemisia argentiflii, Anoidiella inornata, Aleurodicus dispersus, Pieris rape crucivora, Spodoptera litura, Illeis koebelei, Stethorus sp., Tetranychus kanzawai, and Amblyseius ovalis. Of them, T. kanzawai was the most common pest. The population fluctuations of this mite on both transgenic and non-transgenic papayas were similar. Other possible impacts discussed included the impacts on insect-pollinators, conserved or threatened insects, soil insects and birds. It is concluded that the risk of the transgenic papaya to insects, mites and birds in environments were very low.
