2.3 Relationship between index of susceptibility
and anti-nutritional contents
There was a negative correlation between
susceptibility index and anti-nutritional contents
(Figures 2, 3 and 4). Cultivars of cowpea seeds
with low phytate, oxalate and tannin contents tend
to be more susceptible to infestation by
C.
maculatus
than those with high phytate, oxalate
and tannin contents (Table 2).
3 Discussion
Previous study by Ileke et al. (2013) has shown
varietal resistance of thirty-one cowpea cultivars to
cowpea bruchid,
Callosobruchus maculatus
(Fab.)
[Coleoptera: Chrysomelidae] infestation. They
reported that cultivars MIT04K-399-1, MIT07K-299-92,
IT96-610, MIT06K-281-1, MIT07K-187-24, MIT06K-121,
MIT07K-304-9 and EIT07K-291-69 were the most
resistance cultivars tested, while cultivars IFE BROWN
