Abstract
為了瞭解赤眼卵蜂與亞洲玉米螟(Ostrinia furnacalis) 兩族群間之關係，以供大量釋放害蟲天敵技術之參考，本研究乃探討赤眼卵蜂、未被寄生(白卵)和被寄生(黑卵)的玉米螟卵塊在玉米田之空間分布。並由此三者在玉米株上出現之頻度，提出三項可供評估寄生蜂對寄主寄生潛能之指標：1)蜂-白卵株相對百分率，2)蜂-黑卵株相對百分率，3)白-黑株相對百分率。
Investigations were conducted to study the spatial distributions of Trichogramma wasps, unparasitized (white-colored) egg masses and parasitized (black-colored ) egg masses of the Asian corn borer (Ostrinia furnacalis) in a corn field. The results provide information of the relationship between the Trichogramma wasps and the Asian corn borer which may be helpful in improving the techniques of inundative release natural enemies.
