False wireworm (Gonocephalum) damage symptoms in soybean

27/08/2019Posted on
  • Larvae of Gonocephalum are attracted to germinating seeds. The larvae damage the seeds and the developing roots and shoots. Larvae scrape away at least part of the seed coat and feed on the kernel and cotyledons.
  • Adult Gonocephalum destroy emerging seedlings by feeding on the cotyledon leaves, or on the growing tip, or by ‘ring barking’ the stem at ground level. 
  • Adult Gonocephalum are active on the soil surface, and tend to damage dicotyledonous crops more severely than monocots. 
  • This insect eats newly developed seeds in soybean pods and cuts the pods.
