Abstract:

Based on the principle of Probit Analysis, the Data Processing System For Pesticide Bioassay was established with EXCEL. After the user input the insecticide dosages(or concentrations), the trial number of overall insect and dead insects, the procedure will calculate the toxicological regression line(LD-P), median lethal dosage(LD50), 95% fiducial limit of LD50, relation coefficient(r), and chi square test(χ2) in the insecticide toxicological test quickly and accurately, moreover, also can calculate the chi square test and draw the toxicological line.
