銀葉粉蝨（Bemisia argentifolii Bellows & Perring）在四種豆科栽培品種上的族群介量
Population Parameters of the Silverleaf Whitefly (Bemisia argentifolii Bellows & Perring) on Four Legume Cultivars
摘要
在28±1℃定溫下，以黃豆台南選1號、青皮豆台南4號、紅豆高雄5號及綠豆台南3號，飼養銀葉粉蝨（Bemisia argentifolii Bellows & Perring）。由卵發育至成蟲所需時間，在紅豆為21.29日最長，黃豆17.12日最短。由卵發育至成蟲之累積死亡率，以紅豆上者為最高，青皮豆最低。雌成蟲壽命在不同豆科植物上並無顯著差異，而雄成蟲壽命則以在黃豆上6.62日為最長，綠豆上4.50日為最短。雌成蟲產卵量以青皮豆上之25.3粒為最高，紅豆上之15.5粒最低。在不同豆科寄主上各族群介量中，淨增殖率（R_0）、內在增殖率（r_m）及終極增殖率（λ）皆以青皮豆上者為最高，分別為8.94、0.0927、及1.0971；而紅豆上者為最低，分別為3.90、0.0507及1.0504。平均世代時間（T）則以紅豆上27.33日最長，黃豆上23.44日最短。族群倍增時間以紅豆上13.67日最長，青皮豆上7.48日最短。本文並推論，以青皮豆為綠肥作物廣為種植，可能成為銀葉粉蝨孳生溫床，而造成農作物嚴重損失。

The silverleaf whitefly (Bemisia argentifolii Bellows & Perring) was reared on four legume cultivars (Soybean cultivar Tainan Sel. 1 and Tainan No. 4, Adzukibean, and Mungbean) under 28±1℃ to record its life history traits. The longest developmental period from egg to adult was 21.29 days on adzukibean (Kaohsiung No. 5), and the shortest 17.12 days on soybean (Tainan Sel. 1). The female longevity did not differ significantly from each other, while the male longevity reared on soybean (Tainan Sel. 1) (6.62 days) was longer than that on mungbean (4.50 days). The female fecundity of the soybean cohort (Tainan No. 4) (25.3 eggs) was higher than adzukibean cohort (15.5 eggs). The highest net reproductive rate (R_0) was 8.94 on soybean (Tainan No. 4), and the least 3.90 on adzukibean. The soybean (Tainan No. 4) cohort had the highest intrinsic rate of increase (r_m) (0.0927), and the adzukibean cohort had the least (0.0507). The adzukibean cohort took the longest time (27.33 days) to complete its mean generation time (T), while the soybean (Tainan Sel. 1) took the least (23.44 days). The population doubling time was the longest at 13.67 days on adzukibean, and the shortest on soybean (Tainan No. 4) (7.48 days). Accordingly, we remarked that there is a high risk for the wide-area cultivation of the soybean Tainan No. 4 as a manure crop, because it may induce outbreak of the silverleaf whitefly and thus may cause severe damage to other economic crops in Taiwan.
