Abstract EN

Comparisons of two life tables constructed to display alfalfa weevil, Hyper postica (Gryllenhal), populations in south-central Wisconsin, U.

S.

A.

under epizootic and enzootic conditions of fungal disease, caused by Erynia phytonomi Arthur, suggests that the “prepupal” stage provided the greates contribution to population changes under both conditions due to the high mortality rate The principle mortality agents during this stage art E.

phytonomi and the parasitoids complex of Bathyplectes cutculionis and Bathyplectes anurus respectively under the two conditions.
