評估取食木油桐（Vernicia montana Loureiro）花外蜜對基徵草蛉（Mallada basalis Walker）與安平草蛉（Mallada desjardinsi Navás）存活之影響
Effect of Feeding with Extrafloral Nectar Secretion by Wood Oil Tree (Vernicia montana Lour) on Survival of Lacewings, Mallada basalis Walker and Mallada desjardinsi Navás
摘要
本文呈現取食木油桐花外蜜對基徵草蛉（Mallada basalis Walker）與安平草蛉（Mallada desjardinsi Navás）存活影響之試驗結果。其中，花外蜜處理組基徵草蛉與安平草蛉幼蟲較水及空白處理組有顯著較高的存活時間，花外蜜處理組基徵草蛉與安平草蛉成蟲亦有相同情形。取食木油桐花外蜜確實促進基徵草蛉與安平草蛉幼蟲及成蟲具較長壽命，惟無法使基徵草蛉與安平草蛉幼蟲發育及成蟲產卵。取食花外蜜與微膠囊飼料之基徵草蛉與安平草蛉齡幼蟲，對2齡棉蚜的捕食能力沒有顯著差異。綜合試驗結果顯示，取食木油桐花外蜜可有效延長基徵草蛉與安平草蛉幼蟲及成蟲存活時間，且不影響幼蟲捕食能力。木油桐有潛力作為基徵草蛉與安平草蛉保育生物防治的應用資材，然仍應在未來實用前先經田間試驗確認其有效性。

This study investigated the effects of feeding with wood oil tree (Vernicia montana Lour) extrafloral nectar on survival of two lacewings, Mallada basalis Walker and Mallada desjardinsi Navás. Significant higher survival time of M. basalis and M. desjardinsi larvae as well as adults were found on the extrafloral nectar treatment than that on the water and blank treatments. Feeding with wood oil tree extrafloral nectar prolonged substantial longevity of M. basalis and M. desjardinsi larvae and adults. However, consumption of wood oil tree extrafloral nectar did not support the larval development and adult oviposition of both lacewings. Predation capacity on the second-stage of cotton aphid nymphs was not different between extrafloral nectar and microcapsule diet treatments. These results revealed that the extrafloral nectar of wood oil tree could effectively increase larval and adult survival time of M. basalis and M. desjardinsi, but did not affect larval predation capacity. The wood oil tree may thus be potential as a supplementary tool for conservation biological control program using M. basalis and M. desjardinsi. However, field tests are necessary to confirm the efficiency of this treatment before further applications.
