Effectiveness of Plant Oils Against Some Bostrychidae Infesting Cereals in Storage
Published online by Cambridge University Press: 19 September 2011
Abstract
Vegetable oil and palm oil were tested for their ability to suppress the populations of Rhyzopertha dominica Fabr. and Dinoderus distinctus Lesne on maize, sorghum and wheat grains using three dosages of 1 ml/kg, 5 ml/kg and 10 ml/kg. A dosage of 5 ml/kg of each oil, completely protected the three grains from D. distinctus and R. dominica on maize grain. Vegetable oil at 10 ml/kg dosage controlled R. dominica on sorghum and wheat. Palm oil had a similar effect, but did not control R. dominica on wheat even at 10 ml/kg dosage. The populations of R. dominica when treated with 1 ml/kg dosage were not significantly lower at 5% level than the control, with the exception of maize. Percentage weight losses of all grains at 5 ml/kg and 10 ml/kg dosage were significantly lower at 5% level than the control. Oil treatment did not significantly affect the germination of grains and protected the grains from the two pests for only 3 months. The highest population of R. dominica after 2 months of reinfestation was 67 and the highest mean population of D. distinctus was 1.4. The use of vegetable oils in the management of insect pests in storage is discussed.
Résumé
On a expérimenté avec l'huile légumière et l'huile de palme pour savoir dans quelle mesure elles pourraient supprimer les populations de Rhyzopertha dominica Fabr et de Dinoderus distinctus Lesne sur les grains de maïs, de sorgho et de blé, en utilisant 3 doses, allant d'un ml/kg, 5 ml/kg et 10 ml/kg. Au dosage de 5 ml/kg pour chacune des huiles, on a pu protéger les trois grains, des activités de D. distinctus, d'une maniere absolue. Au dosage de 5 ml/kg, on a pu seulement contrôler R. dominica sur les grains de maïs. Au dosage de 10 ml/kg l'huile legumiere a pu contrôler R. dominica sur le sorgho et le blé. L'huile de palme a été l'affet sembable comme l'huile de légumiére au dosage 10 ml/kg, mais elle n'a pa pu contrôler R. dominica sur le blé et ce dosage. A 5% de niveau et au traitement avec les doses d'un ml/kg, les populations de R. dominica étaient significativement plus basses que celles du contrôle, sauf en maïs. A 5% de niveau et au dosage de 5 ml/kg et 10 ml/kg les pertes on poids au pourcentage, étaient plus basses que celles du contrôle. Le traitement par huile na'avait pas significativement influé sur la germination des grains et les a protégés contre des deux ravageurs pendant trois mois seulement. La population la plus élevée de R. dominica après deux mois de réinfestation était 67, tandis que la moyenne la plus élevée de D. distinctus restait à 14. On a discuté l'emploi d'huile légumierés dans la contrôle d'insectes ravageus au stockage.
