SRNSW×SQLD - F1 probit analysis of phosphine sensitivity and test of strain heterogeneity.

Estimated lethal concentrations, slopes and goodness-of-fit tests of probit lines of the parental strains and their F1 progenies when insects were exposed to phosphine for 48 hours at 25°C and 55% r.h. SRNSW = strongly resistant parental strain from New South Wales. SQLD = phosphine sensitive parental strain from Queensland. F1 = first filial generation. n = number of individuals tested. SE = standard error. LC50 = the concentration at which 50% mortality is observed. LC99.9 = the concentration at which 99.9% mortality is estimated to occur. FL = fiducial limits. mg = milligrams. L = litre. df = degrees of freedom. χ2 = chi-squared. P = probability value.*Significant (P**Significant (P***Significant (P
