Abstract Two pollinators, honeybee Apis mellifera and bumblebee Bombus eximius were used to evaluate the pollination effects of large-sized tomatoes in vinyl screen-houses in Taiwan. The flower pollen gathering by B. eximius was observed by using the buzzing behavior, while in honeybee it was normal foraging behavior. Three pollination trials were observed from 25 to 34 days in the cooler seasons during November 2010 and April 2013. Even though temperatures in these facilities reached up to 30°C for a total of 116 hours at midday, both bees successfully pollinated the tomatoes. The results showed that using bumblebees for pollination resulted in a lower malformation rate and a higher number of seeds compared to using honeybees and spraying traditional chemical inducers. The pros and cons of using bumblebees for commercial under the subtropical weather conditions of Taiwan were evaluated and discussed.
摘要 本研究利用二種授粉昆蟲，西洋蜜蜂及精選熊蜂，評估牠們在台灣塑膠布設施溫網室內大果番茄之授粉效果。觀察精選熊蜂訪花時使用振動行為採集花粉，而蜜蜂使用正常行為採集花粉。三個授粉試驗組於2010年11月至2013年4月間秋冬季冷涼氣候進行，每組試驗授粉25～34天，在中午設施內超過30°C的高溫總計有116小時，而西洋蜜蜂及精選熊蜂均有成功替番茄授粉。結果顯示熊蜂授粉方法較蜜蜂授粉與施用生長激素促進結果方法使番茄有較低的不良果率及較高的種子數，本文評估及討論在亞熱帶氣候的台灣，商業化利用熊蜂授粉使用的優劣性。
