Biology of the Brown Marmorated Stink Bug Halyomorpha halys (Heteroptera: Pentatomidae) in the Laboratory

Julio Medal, Trevor Smith, Andrew Santa Cruz

Abstract


The life cycle of the brown marmorated stink bug, H. halys, was studied at the Gainesville, Florida quarantine facility at 25° C constant temperature, 16:8 h L:D and 50–55% RH. Nymphs, which emerged from 32 egg masses, were reared on bean pods and carrots in Petri dishes and checked daily to determine the number and duration of each nymphal stadium and percent survival. Twenty-five recently emerged couples were set-up in clear plastic containers, fed daily with bean pods and carrots, and provided with moisture. The pre-oviposition period, number of egg masses, and longevities of males and females were determined. The general life cycle of this potential crop pest of Florida is discussed.
