Probit Analysis of Correlated Data: Multiple Observations Over Time at One Concentration

Comparison of Volatile Blends and Nucleotide Sequences of Two Beauveria Bassiana Isolates of Different Virulence and Repellency Towards the Termite Macrotermes Michealseni

“…The Student-Newman-Keuls (SNK) test was used to separate the means. Repeated-measures logistic regression via generalized estimating equations (GEE) (Throne et al, 1995;Stokes et al, 2000;Shibata and Shimizu, 2011) was used to estimate the repellency doses (RD 50 ) values required to give 50 % repellency (RD 50 ) for each of the blends. These analyses were carried out using the GENMOD procedure in SAS version 9.2 (SAS Institute, 2008).…”

Oil-Soluble Dyes Incorporated in Meridic Diet of <I>Diatraea</I> g<I>randiosella</I> (Lepidoptera: Crambidae) as Markers for Adult Dispersal Studies

“…However, there was no correlation (P Ͼ 0.05) between the proportion of females mated and the number of neonates per mated female. Dye marker was not transferred by mating, either from (Throne et al 1995). males to females or vice versa. Marker was not transferred from marked males to their progeny; however, the progeny of marked females were marked and retained the color for 3Ð 4 d when reared on control diet.…”

“…Treatment means were separated by the least significant difference (LSD) procedure (Littell et al 1996). Data for development time to 50% pupation and adult emergence were analyzed with probit analysis for correlated data using the log probit transformation (Throne et al 1995). Data were checked for homogeneity of slopes and intercepts, and development times were compared across diet treatments (Robertson and Preisler 1992).…”

Mortality of the Nut-Leaf Weevil Strophosoma Melanogrammum (Forster) and Damage Rate of Needles After Treatment with Entomopathogenic Fungi

“…Mortality data were subjected to a probit program (Mathematica ® , Version 4, Wolfram Research, Inc.), which incorporated natural control mortality, LT 50 and confidence values were calculated using complimentary loglog, logit or probit transformation of proportion of insects killed (Throne et al 1995). Differences between LT 50 values of S. melanogrammum for the two methods (twig inoculation and weevil inoculation) were assessed by comparison of slopes and intercepts of each isolate (Throne et al 1995).…”

“…Differences between LT 50 values of S. melanogrammum for the two methods (twig inoculation and weevil inoculation) were assessed by comparison of slopes and intercepts of each isolate (Throne et al 1995). The significance of the slopes and intercepts of the time-mortality data was tested at the 0.05 level (Robertson and Preisler 1992).…”
