Abstract

The study investigated the comparative efficacy of Moringa ( Moringa oleifera Lamp) powders
from different plant parts (leaf, flower, seed and branch) on the suppression of khapra beetle
(Trogoderma granarium (Everts.) (the 3
rd
larval instar) damage in sorghum grains. Three rates 1%,
2.5%, and 5% w/w of the plant powders were used under laboratory conditions. The experiment was
laid out in Completely Randomized Design (CRD) of four treatments. Each treatment was replicated
four times .Ten larvae of khapra beetle were introduced into each petridish . Mortality of khapra
beetle larvae was recorded after 1, 3, 7 and 30 days. Result indicated that Moringa seeds powder
was more effective in causing khapra beetle larvae mortality. The sorghum grains treated with
Moringa seed powder gave a high range of 7.5- 2.5% larvae mortality compared to the low range of
2.5- 0.0% recorded in sorghum grains treated with Moringa leaves powder at 1 day. A progressive
increase in mortality ranging from 15.0-42.5% in sorghum grains treated with Moringa seed powder
and 12.5- 22.5% sorghum grains treated with Moringa leaves powder were achieved at 5% rate after
3 and 30 days respectively. The LC50 and LC90 revealed that Moringa seed powder to be the most
effective one. Also result revealed that Moringa seed powder is more effective than seed aqueous
extract in the control of khapra beetle larvae. Out of the four powder parts of the Moringa
investigated , seed powder was the most effective biopesticide and thus will be recommended
