台灣鋏蠓幼蟲取食趨性物質探討與餌劑研發

Abstract

This project is aiming at studying the feeding preference of biting midge larvae to various blue-green algae (Cyanobacteria) and green algae as well as developing potential larval baits. Basic ingredient of biting midge baits will include algae as food attractant; several microbial insecticides such as Bacillus thringiensis subsp. israelensis, pyriproxyfen, spinosad; boric acid, etc. Field trials on the control efficacies of different baits will also be conducted to develop effective biting midge control baits that are safe and environmentally friendly.

本計畫擬探討台灣鋏蠓幼蟲對不同種類藍綠藻以及綠藻的取食趨性，並篩選最具誘引效果之藻種進行幼蟲餌劑開發試驗。餌劑開發以藻類為幼蟲取食誘引基質，並添加蘇力菌以色列品系、百利普芬昆蟲生長調節劑、放射菌培養液萃取物賜諾殺、硼砂等為幼蟲誘引取食餌劑之殺蟲物質。此外，計畫亦將進行幼蟲餌劑之田間藥效試驗，以及評估防治成效。以期開發安全有效的台灣鋏蠓幼蟲防治新技術。
