Abstract
倉庫儲穀時常發生害蟲為害，但在穀物出倉後，即有部分害蟲潛伏倉內牆壁器具之縫隙中，待新穀進倉後害蟲因得食料而大量發生。因此，實行倉庫噴佈藥劑消毒治蟲。自從推廣DDT藥劑迄今已久。就殺蟲藥劑而言，應以治蟲經濟且低毒性而安全為先決條件。由於新殺蟲劑相繼問世，為探明其對倉庫害蟲防治效果，自1968年8月至1969年6月在室內進行試驗，茲將所得結果，報告於後，以供推廣參考。
Baythion 50% EC, 40% WP, Cythion 50% WP, 25% WP and DDT 25% EC diluted into 2.5%, 1.67% and 1.25% respectively including with check as tested chemicals. The filter paper were dipped into these chemicals and concentrations separately and put into petri dishes one piece under the cover and another piece on the bottom, let them dry for inoculation granary insects as test one. The other was sprayed the concentration on the inner side of special designed 6 walls which could be closed like one box as test two.
50 adults of Sitophilus oryzae, Rhizopertha dominica and Tribolium castaneum were inoculated into above mentioned petri dishes and closed boxes, after 2 and 4 hours exposure then reared in brown rice which were kept in glass cylinder. After 48, 72 and 92 hours feeding, the dead, alive and morbid individuals were checked under binocular microscope, the morbid and alive individuals were fed in original cylinder and recorded in tables 2 and 3.
