Abstract
Powders prepared from Moringa oleifera Lam. leaf and Allium sativum L. clove were tested
for their influence on Trogoderma granarium Everts adults and larvae in stored groundnut seeds. Four
rates (0%, 2%, 4% and 6% w/w) of the plant powders were used under laboratory conditions. Five
days after treatment, adult mortality recorded in M. oleifera and A. sativum treated groundnut seeds at
2%, 4% and 6% were significantly different (P<0.05) from the control which had no mortality in this
study. The groundnut seeds treated with M. oleifera leaf powder gave a range of 26.6 – 86.6% adult
mortality compared to 53.4 – 86.6% recorded in groundnut seeds treated with A. sativum clove powder
at 1 DAT. A progressive increase in mortality ranging from 40.0 – 93.2% in groundnut seeds treated
with M. oleifera leaf powder and 66.8 – 93.2% in groundnut seeds treated with A. sativum was
recorded at 3 DAT while 100% mortality was achieved at 6% rate in groundnut seeds treated with the
two plant powders at 5 DAT. Counts of number of emerged larvae in plant powder-treated seeds
showed significant difference (P<0.05) compared to control. Higher rate of treatment was significantly
different (P<0.05) in the mean number of adult population compared to control. Allium sativum clove
powder applied at lower rates had greater significant influence in causing mortality of T. granarium
adults, reducing adult population and larvae emergence. The plant powders coupled with other
techniques suggest reliable management of the stored product insect if employed at small-scale storage
of groundnut seeds.
