| 摘 要： | 本文选用敏感性不同的几个田间品系，采用点滴法和浸渍法，室内测定了丙溴磷和辛硫磷、：１、１：２、１：４、１：５和１：６混合的增效程序及其与抗药性的关系。结果表明：（１）所有配比都具有一定的增产作用；随着辛硫磷的比例增大，共毒系数的变化呈抛物线状，以中间比例的共毒系数为最高。（２）丙溴磷和辛硫磷１：１混配时江苏六合品系（对丙溴磷和辛硫磷耐药性分别达３．５倍和２．７倍）的共毒系数比敏感品系高，达到２７７

| Abstract: | Several field strains of cotton bollworm,heliothis armigera,were collected and showed different resistant levels to phoxim and profenofos.These strains were applied to test the synergistic effect of phoxim-profenofos mixture in laboratory.It was found that the toxicity was increased to 3rd instar larvae at five different ratios of mixtures of phoxim with profenofos and the ratios at 1:4 and 1:5 exerted much higher synergistic effects.Moreover,phoxim-profenofos mixture exhibited higher synergistic effect on resistant field strains than that on susceptible strain. |
