Botanical Pesticides and Luring Efficacy of Natural Substances in the Management of Sorghum Chafer under Field and Laboratory Conditions
Abstract: Sorghum chafer, Pachnoda interrupta (Olivier) (Coleoptera: Scarabaeidae: Cetoniinae) is one of the major problems on sorghum. The purpose of this study was to investigate alternative management methods. The studies were conducted under laboratory and field conditions. We tested efficacy of Jatropha curcas, Lantana camara, Croton mychrostaches, Agave sp. (sisal) and Melia azad- rech. The lure effects of banana, guava, local beer residue (Atela), malt and molasses were evaluated. The result from laboratory showed that C. mychrostaches, L. camara, M. azadrech, Agave sp. and J. curcas caused beetle mortality of 44% - 60%, 24% - 64%, 43% - 63%, 45% - 64%, and 65% - 78%, respectively. Also with the result from field it was confirmed that C. mychrostaches, L. camara, M. azadrech, Agave sp. and J. curcas caused beetle mortality of 23% - 56%, 27% - 55%, 36% - 58%, 40% - 55% and 76% - 82%, respectively. In the bait experiment, a higher number of beetles were attracted using banana (>3000 beetles) and guava fruit (>3500 beetles) than the other attractants. Male beetles were more attracted than the female beetles. Thus, we recommended that all botanical pesticides with banana and guava fruits as baits could be used in sorghum chafer management.
