中文摘要 | 蜂蟹蟎 (Varroa destructor) 是台灣養蜂業最嚴重的有害生物,本研究評估利用草酸糖液於蜂群含有幼蟲的狀態下防治蜂蟹蟎的可行性。室內試驗結果顯示,每巢片分別噴灑 4 ml 含 0〜4% 草酸與 30% 蔗糖的草酸糖液,其中以含 3% 草酸者效果最佳,48 h 後殺蟎率可達 81.9 ± 6.3%,而且不會顯著增加成蜂的死亡率。田間試驗於台灣宜蘭的秋季進行,試驗蜂群噴灑含3%草酸與30%蔗糖的草酸糖液,每隔 3-4日 施用 1 次,共施用 5 次,每次施用量則有 2 ml / 巢片與 4 ml / 巢片等兩種處理組;試驗結果顯示,蜂蟹蟎死亡率分別可達 72.6 ± 11.3% 與 82.4 ± 3.8%,兩者具有顯著差異 (p < 0.05);試驗期間,兩種處理對試驗蜂群的封蓋房面積與幼蟲封蓋率皆未出現不良影響,如此說明重複噴灑草酸糖液的方法可於蜂群繁殖期間有效防治蜂蟹蟎。 |
英文摘要 | Varroa destructor is an ectoparasite of serious economic importance to beekeeping in Taiwan. In this study, we evaluated the efficacy of the oxalic acid (OA) sugar solution against varroa mites in brood-right honeybee colonies. In laboratory trials, each comb was sprayed with 4 mL solution containing 0-4% OA and 30% sugar. The 3% OA treatment gave the best results and caused 81.8 ± 6.3% mite mortality at 48 h post-treatment. It also did not cause any additional deaths of treated adult workers. Field trials were conducted in I-Lan, Taiwan. Honeybee colonies received five successive applications (at intervals of 3-4 days) with 3% OA syrup by spraying method with two alternative doses (2 mL or 4 mL OA per comb). These treatments resulted in 72.6 ± 11.3% and 82.4 ± 3.8% mite mortality, respectively. There was a significant difference (p < 0.05) between them. In the experimental honeybee colonies, neither of the two treatments reduced the area of capped cells nor the ratio of larval development into the capped stage. These results suggest that repeated spray applications of OA syrup is effective for the control of varroa mites in brood-right honeybee colonies. |
