中文摘要 | 在76/77至82/83共7個年期之春植F160蔗田內,放置3,960張不育性黃螟卵片 誘引赤眼卵蜂。結果在回收之3,934張誘引卵片中,有629張(16.0%)被赤眼卵蜂寄生,其上 之卵粒被寄生率為7.4%,從而羽化3,172隻赤眼卵蜂,其中611隻為雄蜂,檢查結果T. chilonis佔81.0%,T. ostriniae 19.0%。T. chilonis在二月下半月即開始出現,高峰期 出現於三月上半月至六月下半月間,最多時為六月上半月之每次48.8隻,七月上半月至八月 上半月間略降為每次13.8-18.2隻,八月下半月以後則每次僅0.0-0.5隻。而T. ostriniae 則在三月一開始出現即為其最高峰期,每次15.0-16.7隻,然後自四月上半月持續發生至八 月下半月,但每次僅1.2-10.2隻,九月上半月以後每次僅0.0-2.5隻。至於在78/79至80/81 三個不完整年期放置926張不育性玉米螟卵片誘引結果,卵片被寄生率為2.5%,卵粒被寄生 率為16.5%,羽化83隻赤眼卵蜂,而21隻雄蜂中,16隻為T. chilonis,5隻為T.ostriniae。 |
英文摘要 | In 1987/88 to 1993/94 spring-planted F160 cane fields, 3,960 sterilized Argyroploce schistaceana egg cards were placed to trap the Trichogramma. Of the 3,934 egg cards recovered, 16.0% of the cards and 7.4% of the eggs on the cards were parasitized. Of the 3,172 Trichogramma adults which emerged from the parasitized eggs, 611 were males with 81.0% were T. chilonis; the remaining 19.0% were T. ostriniae. T. chilonis first appeared in the last half of February, reaching a peak of 48.8 adults per trap in the first half of June. This reduced to 13.8-18.2 adults per trap in July to the first half of August and 0.0-0.5 per trap were found thereafter till harvest. For T. ostriniae, the highest peak was only 15.0-16.7 adults per trap in March, then reduced to 1.2-10.2 adults per trap in April to August and were rarely trapped later. On the other hand, parasitizations of 2.5% egg cards and 16.5% eggs were observed when 926 sterilized Ostrinia furnacalis eggs cards were placed over a period of 3 incomplete crop years, 1989/90 to 1991/92. Only 83 adults with 21 males, including 16 T. chilonis and 5 T. ostriniae, emerged from the parasitized Ostrinia eggs. |
