Host-independent artificial rearing of Eucryptorrhynchus brandti (Coleoptera: Curculionidae).
Eucryptorrhynchus brandti (Harold) is a trunk boring pest of Ailanthus altissima in China and is a potential biological control agent for invasive A. altissima in the USA. In this study, we developed a host-independent artificial rearing method for E. brandti adults and larvae, including fresh thin slices of potato for adults and a potato-based diet (referred to as diet 6) for larvae. Adults reared on thin slices of potato oviposited normally and larvae reared on diet 6 exhibited successful pupation and eclosion and short developmental duration. The rates of larval survival, pupation, and adult emergence were 63.3±0.26, 86.7±0.42, and 93.5±0.33%, respectively. This method could be used for the mass rearing of E. brandti.
