評估友善耕作法防治桑木蝨之成效
Evaluating the effect of mulberry psyllid management with friendly farming methods
摘要
本研究探討以友善耕作法防治桑木蝨（Paurocephala sauteri Enderlein）之成效，利用懸掛黃色黏蟲紙及嫩梢採樣方式調查桑園桑木蝨族群密度，評估定時噴灌及釋放基徵草蛉（Mallada basalis Walker）對於田間桑木蝨族群之影響。本試驗比較噴灌及釋放草蛉卵片防治處理，結果顯示噴灌灑水處理區逐週桑木蝨若蟲蟲口減退率為68.1%、29.7%及37.2%，防治率為59.6%；釋放草蛉處理區蟲口減退率為36.3%、77.5%及71.8%，防治率為88.2%。證實定時噴灌處理可快速降低若蟲數量，並干擾成蟲繁殖，基徵草蛉持續釋放2週以上則可達到顯著降低桑木蝨族群密度之效果，本試驗結果可作為桑園友善耕作及實施綜合害蟲管理（IPM）防治桑木蝨之參考。

This research investigated the effects of controlling mulberry psyllid (Paurocephala sauteri Enderlein) by eco-friendly farming methods. Using yellow sticky trap and shoots sampling to investigate the mulberry psyllid population and assess the impact of timed sprinkler irrigation and releasing lacewings (Mallada basalis Walker) in the field. Monitoring the natural population dynamic of mulberry psyllids in the field, caused serious damage to the leaf bud for around a month in the dry weather. This experiment compared sprinkler irrigation treatment and releasing the lacewings treatment after the weekly survey results showed the population decline rate of nymphs was 68.1%, 29.7%, and 37.2%, and the control rate was 59.6% in the sprinkler irrigation plot, while the population decline rate of nymphs was 36.3%, 77.5%, and 71.8%, and the control rate was 88.2% in the releasing lacewings plot. Regular sprinkler irrigation can quickly reduce the number of nymphs because it maybe interferes with mating and ovipositing behavior. Releasing lacewing larvae continuously for more than two weeks can also reduce the pest population. The results of this study could provide information for the management of eco-friendly mulberry gardens and the implementation of integrated pest management (IPM) to control mulberry psyllids.
