The data for this period were analyzed, fitting infestation level to variety, crop, rainfall zone, and year, assuming a logistic regression model with a Poisson distribution of all main effects (variety, crop, rainfall zone, and year). The results showed that all first order interactions were highly significant (p<0.001) and that the overall joint infestation levels remained below the Economic Threshold Level (ETL) of 5% joints bored. This finding suggests that the pest is continuing to be effectively controlled by its two parasitoids Cotesia flavipes and Lixophaga diatraeae. }, url = {http://ageconsearch.umn.edu/record/256724}, doi = {https://doi.org/10.22004/ag.econ.256724}, }
