溫度對青翅蟻形隱翅蟲（Paederus fuscipes Curtis）發育與繁殖之影響
Effects of Temperature on Development and Reproduction of the Rove Beetle, Paederus fuscipes Curtis, Feeding on Nilaparvata lugens (Stål)
摘要
青翅蟻形隱翅蟲（Paederus fuscipes Curtis）屬捕食性昆蟲，為水稻害蟲重要天敵種類之一。本研究於15、20、25及30℃之4個定溫環境下進行，測得卵、幼蟲及蛹期於30℃下最短之發育時間，分別為3.6、11.6及3.0d；發育臨界溫度分別為8.8、9.4及12.3℃；完成各發育期之有效積溫分別為73.4、232.6及53.8日度。以25℃下雌成蟲產卵量最多，一生平均可產190.8粒卵，平均每日產卵量以25℃及30℃最高，分別為2.2粒及2.4粒卵。幼蟲期及雄成蟲之總取食量皆以25℃下為最高，幼蟲期總取食為37.6隻1齡褐飛蝨若蟲，雄成蟲總取食為202.2隻3齡褐飛蝨若蟲；雌成蟲則以25℃及20℃下之總取食量最高，分別為279.8隻及257.2隻3齡褐飛蝨若蟲。依據本研究結果推論，環境溫度約於25－30℃的範圍下，較適合台灣地區青翅蟻形隱翅蟲族群之發育及繁殖。

The rove beetle, Paederus fuscipes Curtis, can predate many species of insects, and is an important natural enemy against insect pests in paddy field. This study was conducted to evaluate the life history parameters of the rove beetle by incubating at 15, 20, 25 and 30℃. The results showed that the shortest developmental periods of egg, larval and pupal stages at 30℃ were 3.6, 11.6 and 3.0 d, respectively, whereas the threshold temperatures of development were 8.8, 9.4 and 12.3℃. The sums of effective accumulated temperature were 73.4, 232.6 and 53.8 day-degree, respectively. The fecundity was highest (190.8 eggs/female) at 25℃, whereas the average of egg-laid was highest (2.2-2.4 eggs/female) at 25℃ and 30℃. The consumed numbers of brown planthopper nymphs were highest at 25℃ for larvae and adult males. There were 37.6 of 1^(st) instar nymphs and 202.2 of 3^(rd) in-star nymphs respectively. However, for the female, the highest consumed numbers were 257.2 and 279.8 of 3^(rd) in-star nymphs at 20℃ and 25℃. The highest daily consumed numbers for larvae and adult females were 2.6 and 3.5 at 25℃, respectively. Therefore, our results suggest that the optimal temperature is around 25-30℃ for the development and reproduction of P. fuscipes local populations.
