Laboratory Evaluation of Some Indigenous Plant Extracts Against Granary Weevil, Sitophilus granarius L. (Coleoptera:Curculionidae)

The world population is projected to be 9.1 billion by the year 2050, and about 70% extra food will be required. One of the main challenges regarding food security is postharvest loss due to insect pests. The overall postharvest grain losses for sub-Saharan Africa could be as high as US$4 billion/year. This is around 15% of the total production of cereal crops. The use of chemical pesticides to reduce grain damage by insects over the past five decades has led to a range of environmental and human health problems. These problems forced researchers to develop alternative methods that have lower adverse effects. Alternative strategies focus on new forms of pesticides that are effective against a specific target species, have fewer residues in food, are unlikely to contaminate the environment, and have lower potential to produce resistance, are biodegradable, and are suitable for use in integrated pest management programs. Some natural plant products effectively meet these criteria and have the potential to manage insect pests of stored grains. However, the understanding of the use of botanical pesticides in storage pest management systems is limited in most parts of sub-Saharan African countries. Effective plant products are not formulated and used widely. To fill the gaps the first step is to synthesize the available information and disseminate it. This review is, therefore, a summary of the current developments and improvements of botanical pesticides in the management of stored grain pests including challenges and future issues in insect pest management.

The present research was achieved to study the toxicity of fixed oils of clove buds (Syzygium aromaticum) and spearmint leaves(Mentha spicata) against larvae and adults of Khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae) and the adults of the drugstore beetle, Stegobium paniceum (L.) by using a new fumigant technique. Germination test was conducted in order to assess the effect of tested oils at the highest concentration on wheat seeds after 24 hrs. A GC/MS analysis was performed to record the main chemical constituents in tested oils. Analysis of the toxicity data showed that, clove fixed oil exhibited the strongest fumigant toxicity against all tested insects. T.granarium larvae showed a very high resistance against both oils comparing with adults. Germination test showed no adverse effect of the tested oils on wheat seeds germination comparing with control. The GC chromatogram of clove buds fixed oil showed that, the main constituents were eugenol (37.43%) eugenol acetate (11.47%), caryophellene (10.44 %), linoleic acid (9.42%) and caryophellene oxide (8.58%). The GC-MS chromatogram of spearmint fixed oil showed that, the main constituents were carvone (33.9%) and limonene (2.7%).

An experiment was conducted to determine the effect of some indigenous plant extracts on the germination of wheat seeds. Six locally available indigenous plants namely. Bazna (Zanthoxylum rhetsa Roxb.), Ghora-neem (Melia) and -Neem (Azadirachta indica A. Juss.) were evaluated. Leaf and seed extracts of plants were prepared by using acetone, methanol and water as solvents. Among the treated wheat seeds. the highest germination was found in Mahogoni treated wheat seeds (95.3711V6) and the lowest in Hijal treated wheat seeds (93.88%). The extracts of all the plants did not show any adverse effect on the germination of treated wheat seeds up to 90 days of treatments.
