This work was carried out to study the effectiveness of different insecticides in controlling soybean insect pests throughout the growing season. Besides soybean stem miner (Agromyza (Melanagromyza) phaseori Coqu.) and soybean root miner (Melanagromyza dolichostigma de Meij.) infesting seedling of soybean, as row treatment with Di-syston, Solvirex, PSP 204 and Thimet G. were very effective. Soybean looper (Plusia agrata Stgr.) 〔Phytometra agrata Stgr.〕, Cabbage looper (Piusia ni Hubner) 〔Phytometra (Trichopiusia) ni Hubmer〕, Taiwan yellow tussoch moth (Porthesis taiwan Shiraki), Bean tussock moth (Dasychira locuples confusa Bremer) 〔Cifuna locuples walker〕and Tobacco cutworm (Prodenia litura Fab.) were found during the growing stage. Li-ma bean pod borer (Etiella zinkenella Treit.), Southern green stink bug (Nezara viridula Lima), Bean bug (Riptortus clavatus Thun.) and Smaller green leafhopper (Chlorita flavesceus Fab.) 〔Chlorita formosana Paoli.〕were found infesting soybean podding stage.
The works were done in spring and summer crops respectively. All insecticides were sprayed once before blooming and additional one (summer) or two (spring) applications after blooming. The insects recorded after each treatment indicating that the best results were obtaind by the treatment of 75% Matacil wp (1:1500), 45% PIN ec (1:1000) and 35% Thiodan ec (1:1000), followed by 40.8% Dursban ec (1:800), 25% Cytrolane ec. (A.C. 47470 1:500) and 50% Parathion ec (1:1000). In the meantime, the spray of 75% Matacil wp (1:1500), 35% Thiodan ec (1:1000), 50% Sumithion ec (1:1000), 25% 6538 ec (1:500) and 50% Ambithion ec (1:1000) were proved to be the effective control of Lima bean pod borer and stink bug.
