'[he present study on the use of containers, indigenous materials and chemicals lbr
the management of insect pests of wheat in storage was conducted in the
laboratory of the Department of Rntomology. Slier-c- Rarigla Agricultural
University (SAU). Ohaka during April 2006 to November 2006. The experiment
was laid out in Factorial RCBD having two factors with three replications. Four
types of' containers such as tin kouta. earthen pot. plastic container and gunny bag
were considered as one Ihctor and different indigenous materials and chemicals
such as neem leaf powder, sand, camphor, naphthelene and an untreated control
were considered as another factor. Three insect pests such as grain moth (Sitotroga
cerea/ella), red flour beetle (Triboliwn castaneum), and rice weevil (Sitophilus
oiyzae) were found to attack wheat grain during the study period. Among them
grain moth population was initially higher but the population of red flour beetle
was always higher than rice weevil. The plastic container and tin kouta showed the
best performance in protecting the wheat from attack of different insect pests
while, gunny hag was less effective. Among the materials, naphthalenc showed the
percentage of grain infestation (11.23-46.36%) was recorded from gunny bag and
in combination with different materials. The lowest percent grain infestation (7.2526.30%)
was recorded from plastic container in combination with naphthclene.
The percent grain infestation fluctuated with temperature and relative humidity
and the percent grain infestation (7.25-26.30%) was low in June atIer 2 months of
storage and gradually increased to a peak in September 2006. A range of 100% -
86.67% of germination of wheat seed was observed in the treatments, tin kouta +
necni leaf powder. plastic container + camphor and plastic container + nccm leaf
powder. The lowest percentage (66.67-73.33%) of wheat seed germination was
observed in the gunny bag ± neem leaf powder and gunny bag sole. Plastic
container and tin kouta in combination with naphthelene provided maximum
(86.73%) germination of wheat seed after six months of storage.
