中文摘要 | 自田間採集甘蔗綿蚜 (Ceratovcuna lanigera) 蟲體,經儲存於冰箱l℃冷藏室或 -2O ℃冷凍室後, 均可作為飼賣食蚜螟蛾 (Isauria aphidivora) 之食餌,但在 l ℃冷藏 者不宜超過 5 個月, 在 -2O ℃冷凍達 42 個月者則仍有 90.0% 之飼成率。 自冰箱取出 2.0 毫升食餌並與直徑 1.3 公分之 5% 蜜液棉球同置於直徑 8.8 公分、 高 1.3 公分之塑 膠培養皿內,然後接種初孵化食蚜螟蛾幼蟲,蓋上皿蓋,置於 25 ± l ℃、30-40 % RH 及 l2L (light): l2D (dark) 光週期下進行飼養,其間只需在第 10 日更換 5% 蜜液棉球一次 。 在培養皿內集體飼養 5-15 隻食蚜螟蛾幼蟲結果,飼成率為 38.3-62.5%,幼蟲期與蛹期 分別為 14.3-16.3 日與 8.0-8.4 日; 距離食餌 1-3 公分處放置 5% 蜜液棉球時, 飼成率 為 90.0-95.0%, 但放置 6 公分處之飼成率僅 55.0%; 又食餌旁 1 公分處放置 5% 蜜液棉 球時,飼成率為 l00.0%,每隻雌蛾產卵 122.5 粒,改放置清水或 5% 糖液棉球時,飼成率 分別為 80.0% 與 86.7%, 每隻雌蛾分別產下 67.5 粒與 86.0 粒卵, 均較前者為差。 以 -2O ℃冷凍達 42 個月之綿蚜蟲體飼養結果, 每毫升食餌可飼獲 4.5 隻食蚜螟蛾成蟲,雌 雄成蟲壽命分別為 17.3 及 18.9 日,每隻雌蟲平均產卵 194.7 粒。 |
英文摘要 | The nymphs of sugarcane woolly aphid, Ceratovacuna lanigera, collected from the field were stored at 1 ℃ or -20 ℃ and then provided as the diet to rear the larvae of an aphidophagus pyralid, Isauria aphidivora. Five to fifteen newly hatched pyralid larvae were placed in a 8.8-cm (dia.) x 1.3-cm (height) plastic petri dish containing 2 ml of diet and a 1.3-cm (dia.) cotton ball soaked with 5% honey solution. Then the plastic petri dish was placed at 25 ± 1 ℃, 30-40% RH and 12L: 12D photoperiodism, and the cotton ball was renewed once during the rearing. As the results, 38.3 to 62.5% of the larvae pupated and all the recovered pupae emerged. When a 5% honey cotton ball was placed 1-3 cm apart from the diet, 90.0-95.0% rearing was observed, while only 55.0% rearing was obtained when placed 6 cm apart. A 100.0% rearing resulted and each female deposited 122.5 eggs when a 5% honey cotton ball was provided during the rear- ing. On the other hand, the percent rearing was 80.0-86.7%, and each female deposited 67.5-86.0 eggs when tap water or a 5% dextrose cotton ball was provided together with the diet. Rearing of the predator with the aphid nymphs stored at -20 ℃ for 42 months indicated that 1 mi of stored nymphs could sustain the development of 4.5 adult preda- tors. The female and the male adults lived for 17.3 and. 18.9 days, respectively, and each female deposited 194.7 eggs. |
