Damage CausedĬutworms can cause significant damage to a wide range of crops, including corn, soybean, cotton, and various vegetable and fruit crops. The entire cutworm life cycle typically takes around 1 to 3 months, depending on the species and environmental conditions. Within two to three weeks, adult moths emerge from the pupae and begin the life cycle again. After the feeding period, which lasts for a few weeks, the cutworm larva enters the pupal stage, usually in the soil. Within a few days, the eggs hatch into larvae, which are the damaging stage of the insect.ĭuring their larval stage, cutworms feed primarily at night and curl up during the day. The adult female moth deposits eggs on plants or soil. These larvae undergo four primary life stages: egg, larva, pupa, and adult moth. Understanding Cutworms Life CycleĬutworms are the larval stage of various moth species. Implementing an integrated pest management strategy that includes both chemical and non-chemical methods can greatly reduce the risk of cutworm damage and promote healthier crops in the long run. By keeping track of insect activity, one can make informed decisions about when to apply insecticides for optimal results. Successful management of cutworms also involves regular monitoring and an understanding of their life cycle. It is important to note that the choice of insecticide, application methods, and timing are all factors that can influence the overall effectiveness in controlling cutworm populations. These chemical compounds have been found to be both toxic and persistent when applied as foliar sprays, making them an effective solution against cutworm infestations. One proven method for controlling cutworms is the use of pyrethroid insecticides.
