Rearing protocol and density trials of the brown marmorated stink bug (Hemiptera: Pentatomidae) in the laboratory
Keywords:
Halyomorpha halys, rearing protocol, density-dependent factorAbstract
Summary
The following procedures provide a framework for rearing Halyomorpha halys (Stål) (Hemiptera: Pentatomidae). The insects were cultured in slightly modified, commercially available bug dorms. A diet of organic beans, organic carrots, organic sunflowers seeds, and water was replaced on the maintenance days of Monday, Wednesday, and Friday to maximize freshness of the food. Egg masses were collected and bug dorms were cleaned on maintenance days as well. Adult density affected the number of egg masses laid per female and female survival in this protocol. Densities greater than 2 mating pairs per bug dorm significantly reduced egg mass production per female and led to shortened adult female longevity.
Sumario
Los siguientes procedimientos proveen un marco para la cría de Halyomorpha halys (Stål) (Hemiptera: Pentatomidae). Se criaron los insectos en los dormitorios ligeramente modificados de los comercialmente disponibles para insecto. Una dieta de granos orgánicos, zanahorias orgánicas, semillas de girasol orgánicas y agua fue reemplazado en los días de mantenimiento de los lunes, miércoles y viernes para maximizar la frescura de los alimentos. Se recogieron las masas de huevos y se limpiaron los dormitorios de los insectos en los días de mantenimiento también. La densidad de adultos afectó el número de masas de huevos puestos por hembra y la sobrevivencia de las hembras en este protocolo. Densidades de más de 2 parejas de apareamiento por dormitorio de insecto redujeron significativamente la producción en masa de huevos por hembra y produjo una reducción en la longevidad de las adultas hembras.
