Hyperparasitoids: A threat to IPM of aphids on sweet pepper?


Abstract: This paper provides a brief introduction to hyperparasitism and explores the concept atvarious trophic levels. Studies in commercial pepper crops in the UK during 2010 are describedin which seven different species of hyperparasitoid were detected. In addition, observations ofintraguild predation are reported, which could also impact on the control of aphids by primaryparasitoids. Finally, the paper considers how a thorough understanding of hyperparasitoidforaging behavior could enable us to interrupt the process and thereby reduce the commercialimpact of hyperparasitism.
