Influence of Mahanarva fimbriolata (StГҐl) (Hemiptera. Cumulative insect-days were calculated for cereal leaf beetle larvae (Ruppel 1983). Cumulative larval-days, grain moisture, and bushels per acre were analyzed in separate analyses as the dependent variable using a general linear mixed models approach (PROC MPXED; SAS Institute 2008a )., Percent control is the usual index for the efficacy of an insecticide or other control measure against an insect. This places the emphasis on the proportion of the population that is eliminated..

Food Quality Protection Act of 1996, EPA considers the special sensitivity of infants and children to pesticides, as well as aggregate exposure of the public to pesticide residues from all sources, and the cumulative effects of pesticides and Cumulative insect-days were calculated according to Ruppel’s method by using the average number of F. occidentalis (adults and larvae) and O. majusculus (adults and nymphs) per plant. Number per plant was obtained as the mean insect counts on the three leaves sampled at each date.
