Kudzu Bug

(Megacopta Cribraria)


Interesting Facts & Information

  • Harmless to people and houseplants​

  • Lay 26 to 274 eggs at a time, and many of them will not survive​

  • Have a defense mechanism in which they release a bad smelling pheromone, this is where they get one of their common nicknames, Globular Stink Bug​. This mechanism can become a nuisance to people because of the smell and it is known to leave a brownish stain when it is released​ (Poplin & Hodges)

  • Can be found living in any areas surrounding kudzu vines are growing​

  • Multicellular and Eukaryotic

  • Reproduce Sexually

  • Omnivores, Kudzu vines are their main food source

Origins of the Kudzu Bug

  • Native to Asia, most specifically in the southwestern islands of the Japanese archipelago, India, and China​

  • They made their way to the Southeastern part of the United States, originally being discovered in Georgia in 2009 (Poplin & Hodges)​

  • The have since spread to 13 states(including South Carolina)​


Taxonomy

Kingdom: Animalia​

Phylum: Arthropoda​

Class: Insecta​

Order: Hemiptera​

Family: Plataspidae​

Genus: Megacopta​

Species: Cribraria​


Pests of the Southeast

  • In their native regions of Asia, the Kudzu bugs are not known to be pests for any reasons​

  • However, in Georgia and South Carolina they are known to be an annoyance to homeowners and a pest to soybean fields across the states.​

  • The Kudzu Bugs gather in large groups on the soybean crops and they feed on the leaves and stems, which leads to abnormal pod growth.​

  • Their infestations can lead to more than a 50% loss in any given soybean field (Blount etc.)​


Kudzu Bug Research

  • Since the discovery of the bug in Georgia in 2009 they have become a pest of soybeans, kudzu, and other legume type plants. Some non-legume hosts have also been reported​

  • There was a research study done from 2012-2013 to test what crops grown in the southeast would generate the most development of Kudzu Bug. This was carried out to further understand where the bugs will easily cause an infestation problem.​

  • They tested 18 different plants to see how well the bug developed on each host ​


  • Chart shows the amount of fully grown Kudzu Bugs on each host crop​

  • Shows which hosts were best for the development of the bugs​


Data Analysis & Conclusion

  • It was found that soybeans, edamame, and pigeon peas were the suitable legume hosts.​

  • Fava beans showed low levels of development and the rest showed no significant amount of development.​

  • The study’s conclusions and results have been used to help understand what crops need to be looked at and protected from Kuzdu Bug infestations in the Southeast​

  • The Kudzu Bug is very clearly an agricultural pest in the Southeastern portion of the United States based on this research study
