means were subjected to exploratory analyses to assess the assumptions of the normality of residuals, homogeneity of variance of the treatments, and additivity of the model to allow for parametric tests.
The present study was designed to determine integrated effect of synthetic insecticides and nitrogen fertilizer on aphid
population in canola crop.
All allelopathic water extracts investigated in our studies had a significant effect on aphid
