中文摘要 | 殺鼠劑的施用方式與殺蟲劑或殺菌劑不同,必需以餌劑之型式引誘鼠類取食,才能產生藥效。現今臺灣地區推廣使用之殺鼠餌劑乃以 70 % 穀物(主要為糙米或飼料米)及 30 % 石蠟所製成之蠟米餌劑,於田間使用時對鼠隻之誘引性常為農民所詬病,且餌劑中添加誘引物質以提高取食率的作用會為石蠟所抵消。為改進殺鼠餌劑對鼠類的誘引性,研製新型不含石蠟的麻糬式餌劑, TPB-04 。於室內喜好性試驗中, TPB-04 與蠟米餌劑同時餵飼時,除赤背條鼠對 TPB-04 餌劑的取食率為 75.1 % 外,其餘鬼鼠、小黃腹鼠、緬甸小鼠、溝鼠及屋頂鼠對 TPB-04 之取食率皆大於 90 % 。 TPB-04 餌劑置於田間,經連續 7 日下雨,總降水量為 74.2 mm 之淋洗後,除在與地面接觸的部位產生黴菌菌落外,外觀並無明顯變化;於同時給與新鮮蠟米餌劑之室內喜好性試驗中,小黃腹鼠對其取食率仍達 53 % 。於二次田間測試中,鼠隻對 TPB-04 餌劑的取食率亦明顯大於對蠟米餌劑的取食率,分別為 100 % 及 83 % 。此結果顯示, TPB-04 餌劑除具有蠟米餌劑耐貯藏、於田間不易變質的優點,且更為鼠類所喜好取食,應為一深具潛力之鼠害防治用餌劑。 |
英文摘要 | Effects of Solanum viarum leaf extracts on stimulating the oviposition of Helicoverpa armigera (H ü bner) were evaluated in 2-choice I-tubes bioassay (250 cm long x 30 cm in diameter). Different types of solvent-extracts were placed on filter paper (90 mm) and compared their oviposition stimulation against the check with only the respective solvent in each treatment. Oviposition was evaluated by the mean number of eggs laid on both net and cylinder. There were significant difference in the mean number of eggs laid on the net containing the leaf extracts with acetone and hexane airtight acrylic, hexane and methylene chloride dipping. However, the aqueous extract trapped in diethyl ether from the steam distillation appeared to inhibit the oviposition of H. armigera . From the mean number of eggs laid on the cylinder, it showed that only the dipping in hexane and methylene chloride significantly stimulated the oviposition of H. armigera but no significant difference was observed in the extracts from the other methods. |
