Effect of Pea and Lentil Development on Reproduction and Longevity of Thyanta pallidovirens (Stål) (Hemiptera: Heteroptera: Pentatomidae)

The effects of pea, Pisum sativum L., and lentil, Lens culinaris Medik., development on reproduction and longevity of Thyanta pallidovirens (Stal) were evaluated in the laboratory. Stink bug reproduction and longevity were both significantly affected by the host plants’ developmental stage. The greatest number of eggs, with the highest number of viable eggs and eggs per clutch, were laid and the longest life span occurred on peas or lentils with mature pods. Insects given peas or lentils with flowers and immature pods had shorter life spans and produced significantly fewer total eggs, eggs per clutch, and viable eggs. Almostno eggs were produced by females given seedlings or only flowering host plants.
