摘要

青枯葉蛾（Trabala vishnou Lefebure）在台灣是枯葉蛾科中為害林木較常見的種類之一，其寄主植物多達16科32種。在光週期12L:12D，相對濕度65 ± 5%之15與25℃之恆溫箱中，以欖仁葉進行飼育。在15與25℃下，幼蟲發育期分別為103.1與52.9日；1~6齡幼蟲之發育期分別為15℃之15.4、13.3、16.8、14.7、18.9及24.1與25℃之5.8、7.6、5.6、8.8、11.0及15.1日；蛹期分別為39.9與18日；成蟲壽命分別為12.4與9.3日。雄蟲與雌蟲之後胚胎發育期，在15℃下分別為144.8與161.3日；在25℃下分別為75.6與86.3日。雌雄之性比（♀:♂）依成蟲羽化數量計為1.1:1。在兩個溫度下，每隻雌蟲一生之產卵量分別為100.4與146.9粒。文中對此蛾各蟲期形態特徵有詳細之描述與圖示。

Trabala vishnou Lefebure is one of the common pests of Lasiocampidae in Taiwan. Recorded host plants include 32 species in 16 families. The life history of T. vishnou was investigated at constant temperatures of 15 and 25℃ with 65 ± 5% RH and a 12L:12D photoperiod using leaves of Terminalia catappa. At 15 and 25℃, the larval development took 103.1 and 52.9 days; 1^(st) to 6^(th) instar larvae took 15.4, 13.3, 16.8, 14.7, 18.9 and 24.1; and 5.8, 7.6, 5.6, 8.8, 11.0 and 15.1 days, respectively, to complete their development. Pupal development was 39.9 and 18 days, respectively. The longevity of adults was 12.4 and 9.3 days, respectively. The postembryonic development period of males and females was 144.8 and 161.3 days, respectively, at 15℃; and 75.6 and 86.3 days, respectively, at 25 ℃. A sex ratio of 1.1: 1 (♀:♂) was estimated by the number of adults which emerged. The number of eggs laid by a female was 100.4 and 146.9, respectively, at 15 and 25℃. The external morphology of each stage is described and illustrated.
