Abstract
(1) 綜觀本試驗結果 Thuricide 90 TS ，對於多數蔬菜鱗翅目害蟲均有良好之防治效果，如比較各季節之防治效果，則冬季為最有效，春秋二季次之，而夏季較差，其原因除害蟲種類不同外，因溫度、溼度、降雨及紫外線等均可能影響蘇力菌本身之殺蟲能力。以臺灣6-8月份言之，乃溫度最高，陽光最強之時期，此等氣象因能對Thuricide之胞子發芽及活性度有不良之影響，故防治效果效差，雖然蕃茄夜蛾之幼蟲對Thuridide 之感染力最差，但對蘇力菌較具敏感之小菜蛾，在夏季防治時，亦較其它季節為差，故蘇力菌之防治害蟲，在田間應用時受氣象因子影響頗力。
Thuricide 90 TS, a microbial insecticide, was used in field test to determine its effectiveness in controlling insect pests on Cruciferous vegetables. During the tests, Thuricide diluted at 1:500, 1:1000 and 1:1500 respectively in water were tested in comparison with four organophosphate insecticides: DDVP, Elsan (Cidial), Phosdrin and Bayrusil E. C. both at 0.05%. Seven treatments plus one control (untreated), with individual plot size of 36m2 (6m × 6m) were arranged as randomized complete block design.
