Ogungbit et al., 2014, Bio-pesticide Treated Jute Bags: Potential Alternative Method of Application of Botanical Insecticides against Rhyzopertha dominica (Fabricius) Infesting Stored Wheat, Molecular Entomology, Vol.5, No.4 30-36 (doi: 10.5376/me.2014.05.0004)

Bio-pesticide treated jute bags were evaluated for their insecticidal flurry against Rhyzopertha dominica infesting stored wheat. The jute bags were separately treated with 2, 4, 6 and 8 ml dosage of Eugenia aromatica oil while some bags were deep-soaked in 100 ml of the oil. Untreated bags were set as controls. The result obtained showed that the treated bags significantly affect survival of insects as they all achieved above 55% mortality within 72hours of exposure. Moreover, it was observed that jute bag that was deep-soaked in 100ml of E. aromatica had the greatest mortality effect on the beetle as it achieved 100% mortality within 48hours of exposure. All the treated bags were found to reduce or prevent the weight loss and damage of the stored wheat after 42 days of storage. The ability of these bags to prevent the weight loss and damage of the stored wheat reduced after six months of storage as only the deep-soaked jute bag was able to prevent seed weight loss and damage. The oil treated jute bags have no effect on the colour, odour and acceptability of the wheat grains stored in them. The result also showed that the treated jute bags did not affect the viability of the stored wheat after six months. Base on the result obtained, the use of E. aromatica-treated jute bags may serve as an acceptable method of applying botanical pesticides in protection of stored grains.
