Susceptibility Of Stored African Yam Bean (Sphenostylis Stenocarpa) And Mung Bean (Vigna Radiata) To Levels Of Initial Infestation Of Callosobruchus Maculatus (Fabricus) (Coleoptera: Chysomelidae)
ABSTRACT
African
yam bean (Sphenostylis sternocapa) and Mung bean (Vigna radiata) are major
pulses grown in Nigeria and other parts of the world for their high protein
content. The effects of levels of initial infestation of Callosobruchus
maculatus on S. sternocapa and V. radiata was evaluated under laboratory
conditions (temperature of 28+2°C and relative humidity of 60+5%) at the
Department of Zoology and Environmental Biology Laboratory of Michael Okpara
University of Agriculture, Umudike from July to September, 2018. S. sternocapa
and V. radiata seeds weighing 18g and 8g,respectively and bearing 0, 1, 2, 3
and 5 eggs was poured into 200 mls glass jars covered with muslin net and
allowed for 30 and 60 days to develop to adults. The experiment was laid out in
a completely randomized design (CRD) with four replicates. Results from data
analysis showed that significantly (P < 0.05) higher number of adult C.
maculatus emerged from batches bearing 5 eggs (14.25 and 8.25) at 60 DAI than
others. Seed weight loss in varieties showed that significantly (P < 0.05)
higher weight loss was recorded in S. sternocarpa bearing 5 eggs (39.28%) but
those bearing 2 and 3 eggs (32.07% and 28.42%) were not significantly (P >
0.05) different from each other but were significantly (P < 0.05) different
from 1 egg (25.09%) and control (0.00%). Meanwhile, weight loss in V. radiata
was not significantly different (P < 0.05) from each other but was
significantly different from control (0.00).
