中文摘要 | 外米綴蛾幼蟲以碎粒糙米飼養於30±1℃,70±5% RH,12L:12D之生長箱中,幼蟲 的密度會影響此蛾發育與繁殖。在100g碎粒糙米接卵100~800粒,所得存活率隨著卵密度 增加而逐漸降低,且發育期則隨卵密度增加而延長。成蟲之體重、產卵數,因卵密度超過500 粒時漸減。每100g碎粒糙米接卵500粒時產卵量最高,而雌蛾體重與產卵數有直線迴歸之 關係,即雌蛾體重愈重,產卵數愈多。以不同厚度食物飼養外米綴蛾幼蟲時,其食物厚度在 3.0~4.0cm間得較高之羽化率和較短發育期,但在食物厚度為2.0~2.5cm時飼養所得雌蛾產 卵數最高。因此飼養外米綴蛾幼蟲時以食物厚度2.0~2.5cm所得之蛾適於採卵。 |
英文摘要 | In this present paper, rice moth Corcyra cephalonica(Stainton) larvae were reared on crushed brown rice in a growth chamber at 30±1℃, 70±5% RH, with a 12L:12D photoperiod (light was turned on at 06:00 and was off at 18:00). The development and fecundity of the month were affected by the density of larvae in the media. As the rice moth eggs density per 100g of crushed brown rice increased, the survival rate of the adults developed from the media reduced, the developmental period increased. The greatest number of deposition of the mot could be obtained when the larvae reared at the density of 500 eggs per 100g of the crushed brown rice. The fecundity was positively correlated with body weight of female moth. The larvae reared in the food thickness of 3-4 cm, had shorter development period and the greatest number of moth emerging. Larvae reared in food of 2.0-2.5 cm thickness developed into moths which deposited most number of eggs. |
