Oviposition sites of Orius insidiosus (Say) and Nabis spp. in soybean (Hemiptera: Anthocoridae and Nabidae) [USA]

Eggs of Orius insidiosus (Say) and 2 Nabis species were sampled in soybean from June through August 1979. Densities of O. insidiosus eggs and those of Nabis roseipennis Reuter followed similar seasonal trends with peak densities occurring in late July; eggs of Nabis americoferus Carayon were relativ...

Description
Summary:Eggs of Orius insidiosus (Say) and 2 Nabis species were sampled in soybean from June through August 1979. Densities of O. insidiosus eggs and those of Nabis roseipennis Reuter followed similar seasonal trends with peak densities occurring in late July; eggs of Nabis americoferus Carayon were relatively rare throughout the season. Apparent preferences for oviposition sites were noted for O. insidiosus and N. roseipennis; the former oviposited most frequently in leaf petioles while the latter oviposited most often in median leaflet petiolules. Stratification of oviposition sites along the vertical aspect of the soybean plant also was detected.
