So, what’s new in this study? The paper, in seeking to overcome earlier concerns about our knowledge limits on this topic, proposes a new model. It’s based on environmental variables of multiple characteristics of weather, soil, crop types, and land/crop management. These variables feed into the growth and development traits of both insects and crops which then influence each other. For insects, the life cycle of eggs, larvae, pupae, and adults is covered. For crops, attainable and actual yields are included for different plant parts. Damage to and economic losses from crops could then be calculated, although these tasks are not completed since they were not within the paper’s scope.
