Termpaper Part 2

This document summarizes information on various soybean and tomato pests, including the beanfly, black cutworm, pod borer, fruit worm, leafminer, and whitefly. It describes the characteristics, life stages, damages, and management practices for each pest. The beanfly, pod borer, and fruit worm lay eggs that hatch into larvae or maggots that feed on and damage young soybean pods, tomatoes, and leaves. The black cutworm is a nocturnal caterpillar that can severely damage seedlings. Management strategies include removing alternate hosts, practicing sanitation, using pheromones and light frequencies, and planting trap crops to control pest populations.
