Summary

Fourteen cow peas were tested for susceptibility to infestation and damage by Callosobruchus maculatus (F.) in the laboratory. IT81D-897 and Popse showed the lowest damage over a 3-month test period. 100-seed weight was not significantly correlated with seed damage.

The developmental period of G. maculatus was significantly longer in IT81D-897 and Popse than in other cow peas tested. Percentage adult emergence and fecundity of females were also lowest in these two cow peas.
