Body weight and reproductive status of two nabid species (Heteroptera: Nabidae) in Indiana
Environmental Entomology 21 (1), 191-196
Abstract: Two nabid species, Nabis roseipennis Reuter and N. americoferus (Carayon), were collected from alfalfa fields in Indiana in 1988 and 1989. Body weights and numbers of eggs at dissection were recorded and compared within and between species by location and time. The numbers of eggs at dissection were regressed on body weight, and compared between species. Overall, N. roseipennis were found to weigh more than N. americoferus. N. americoferus appeared to have a minimum weight threshold for egg production. No such threshold was evident for N. roseipennis. Egg-to-weight relationships suggested that N. americoferus was more efficient at producing eggs than N. roseipennis, which helped to explain interspecific comparisons of fecundity. The findings of the study are compared to similar studies of nabid reproduction and related to the potential use of nabids in pest management.
