Abstract : numerous mushrooms are toxic to insects. to identify the chemicals involved in insecticidal activity, the toxicity of 14 species has b een studied for water solubility, thermolability, and dialysis. the data strongly s uggest that proteins are responsible for most of the insecticidal avtivity in mu shroom fruitbodies and may be a source of genes available for plant protection a gainst insects. among proteins, lectins and haemolysins are good insecticide candi dates because the toxicities are not affected by protease

    文摘:許多蘑菇都對昆蟲表現出毒性.為了證實與殺蟲毒性有關的化合物，對14種蘑菇的毒性在水溶性、熱敏性和可透析性等方面進行了研究.研究數據表明，蛋白質對大多數蘑菇子實體的殺蟲活性起著重要作用，也許是一種可以用於植物抵抗害蟲的基因源.在數種蛋白質中，凝集素和溶血素因不受蛋白酶的影響而成為良好的殺蟲劑候選材料
