A BASIC programme for hyperbolic fitting has been developted. By using this programme, the simulation on the lethal profile of nine n-alkyl acyl derivatives of eodo1,7,7-trimethylbicyclo [2.2.1 ]heptan-2-ol on Sitophilus zaemais L. were performed. From the estimated M and K value, the insecticidal mechanism of these esters was proposed. 以電腦基礎語言建立解飽和曲線(Hyperbolic Curve)之程式。用本程式計算endo-1,7,7-Trimet-hylbicyclo[2.2.1] heptan-2-ol 正烴基氫氧酸衍生物對玉米象(Sitophilus Zaemais L.)之致死曲線，並以所求得之常數M與K推論此酯類衍生物對玉米象的作用機序。
