| dc.description.abstract | The use of plant essential oils as repellents and antifeedants may prove an excellent alternative for rodent control. However, being volatile, their effect is wiped out very quickly. By microencapsulation, the desired oil may be enclosed in extremely tiny amounts in microscopic particles having thin coatings of wall material with limited permeability. This reduces rate of evaporation of the oil thereby increasing its efficacy for a longer period of time. Laboratory experiments were conducted to study the persistence of repellent and antifeedant effects of eucalyptus oil loaded in microcapsules against male Rattus rattus. For evaluating the antifeedant effect, microcapsules containing three different concentrations of the oil (3, 5 or 7%) were mixed in plain bait at 5, 10 or 20% concentrations. Significant antifeedant effect was found at all the concentrations of the oil. Overall, no significant difference was found in antifeedant index among microcapsules containing 3, 5 and 7% eucalyptus oil as well as among three concentrations (5, 10 and 20%) of microcapsules. Significant repellent effect of the oil was observed on all the 7 days at 5% concentration. Scanning Electron Microscopy of microcapsules loaded with oil revealed crimpy surface with lumps. Maze experiment revealed reduced movements and activities in zone treated with microcapsules containing 5% oil as compared to untreated zone. Under simulated store conditions, microcapsules containing 5% oil showed significant repellent effect which persisted for all the 15 days of experiment. Present studies suggest the use of microcapsules containing 5% eucalyptus oil to reduce rodent damage in storage. | en_US |
