Occurrence Patterns and Control Methods of the Soybean Hawkmoth
Damage symptoms: The soybean hawkmoth feeds on leaves as larvae. Young larvae eat leaves into a net-like, notched pattern, and after the third instar the larvae can eat all the soybean leaves, preventing the plants from setting pods and greatly affecting yield. Occurrence patterns: Mid-to-late July to early August is the peak period for adult egg-laying, late July to late August is the peak period of larval damage, and in early September the light-yellow mature larvae enter the soil to overwinter. Life habits: Adults: Adults hide by day and come out at night, and have a strong tendency toward black light lamps. They begin activity in the evening and are strong fliers with strong migratory ability. They mate at night, and lay eggs 3 days after mating. Eggs are mostly scattered on the undersides of soybean leaves, generally 1 to 2 eggs per leaf, and the eggs hatch into larvae after about 7 days. Larvae: Larvae are photophobic, mostly staying on the undersides of leaves or on stems during the day, and feeding strongly at night; on cloudy days they can feed all day. First and second instar larvae eat little and generally do not move between plants to cause damage; after the fourth instar they have the habit of moving to cause damage; fifth instar larvae show a sharp increase in food intake, accounting for about 90% or more of the total food consumption. The larval stage lasts 30 to 35 days.
