Abstract
Endrin, gusathion and diazinon were tested for control of two important cotton insects, namely, leafhopper Chiorita biguttula Ishida and spiny bollworm Earia fabia Stoll infesting cotton crops after a typhoon at Tai-dou-kung, Chiayi county, in Taiwan in 1956. In all treatments. excellent results were obtained from high concentrated plots applied at intervals of 10 days. It was revealed that endrin and gusathion gave best results and also gave about equal effectiveness against this pest. The treated plots of endrin and gusathion in the yield of seed cotton were 1356 to 1380 kgs per hectare as the index of increased yield was at 143.49% to 146.03% and all plots treated with diazinon were less effective. According to this data, the control of cotton pests should be very important for reducing damage to cotton following typhoons.
於民國45年9月15日棉田遭遇強力颱風黛納小姐襲擊後，損失不貲，乃以繼績進行藥劑防治兩種主要棉蟲為棉浮塵子Chlorita biguttula Ishida與棉金鋼鑽蟲Earias fabia Stoll試驗，並在本分所臺斗坑農場舉行，參加殺蟲劑為安特靈(19.5% Endrin)，克殺聖(20% Gusathfon)與大利農(60% Diazinon)三種乳劑。本試驗結果，其中以安特靈與克殺聖乳劑之高濃度處理，並間隔10天施藥1次者為最優，每公頃籽棉產量達1,356-1,380公斤，增產指數143.49%-146.03%唯獨大利農諸處理最差。玆據本試驗各處理中產量統計分析結果，顯示颱風後加強蟲害防治，殊為重要，仍可挽救部份損失。
