Diabrotica barberi Smith & Lawrence and Diabrotica longicornis (Say) (Coleoptera: Chrysomelidae) are considered to be sister species, and it has been proposed that the two species may hybridize under field conditions. The objective of this study was to examine genetic and morphological characters of D. barberi and D. longicornis for evidence of field introgression. Both species were collected from sympatric and allopatric areas. Amplified fragment length polymorphisms and morphological characters (color and head capsule width) were used to examine variation within and among populations of D. barberi and D. longicornis. Relatively little of the overall …
