Overview of the laboratory performance of Acanthoscelides obtectus on seeds of 26 sampled bean populations from Mexico (N = 5′847).

N = number of emerged A. obtectus or D. basalis females for each bean population“NA” indicates values which could not be computed.For each bean population the mean weight of emerged A. obtectus, the mean developmental time and the standard errors were recorded. For the survival rate of A. obtectus, the standard deviation was computed. In the case of Dinarmus basalis, the mean tibia length and the standard error were measured (N = 564). Parasitism rates were computed by dividing the number of emerged parasitoids by the number of potential hosts (sum of bruchids + sum of parasitoids).
