Stink bugs
scouted Dec. 3, 2020
- Scientific Name
- Pentatomidae
- Background
- Soybeans of Bladen county, group V, were scouted and observed 45% of the field was affected by random mycelium and rot that affected the pods.
- Conclusion
- The issue was identified as Stink bugs, family Pentatomidae. The are three species that typically affect soybeans, the green stink bug, southern green stink bug, and the brown stink bug. They affect fruiting soybeans, reaching peak populations late August to early October. Damage from Pentatomidae is due to digestive enzymes found in the bug's saliva. Green stink bug species can be treated with acephate and pyrethroid insecticides. Brown stink bugs can be treated with a high concentration of acephate or bifenthrin. In North Carolina, the brown stink bug is the primary pest. They can cause three kinds of damage, in early vegetative stages plant can be stunted, or plants can be killed, in the pre-tasselling stage ears can be crooked and have missing kernels and in the reproductive stages kernels size and weight can be reduced and secondary pathogens can be introduced leading to aflatoxin or fumonisin contamination.
