Pest Information

Soybean looper (Chrysodeixis includens) are an important agricultural pest with an exceptionally broad geographical range. Soybean looper can be found throughout the Americas but are especially prevalent in the Southern USA and South America. Annual migration occurs to the northern States and Canada from their overwintering area. In warmer climates, soybean loopers can have up to 11 generations per year and can complete its lifecycle with 30–35 days.

Early instar larvae begin feeding on the underside of the leaf, producing small holes that do not break through the upper surface of the leaf. Larger larvae cause more conspicuous damage. Plants can be severely defoliated and stunted, reducing plant vigor and yield.

  • Female moths can lay 300–600 eggs, usually over a 10–12 day period
  • Larvae hatch 3 to 6 days after being laid
  • The larvae will feed for 2–4 weeks, consuming about three times its own body weight per day

Soybean looper are polyphagous however soybean is the preferred host. They will also feed on other important agricultural crops such as Cotton, Corn, Peas, Cucurbits, Tomatoes, Peppers and Floriculture crops.
