dc.description.abstractRodents are the serious pests in both agricultural and commensal situations. Many ecofriendly, easily available, economically viable plant based repellents are developed for reducing rodent damage. Repellent behavior of house rat (Rattus rattus) was studied using 2.5% methyl anthranilate (MA) in Feed Scale Consumption Monitor (FSCM) and in I-maze under Ethovision Video Tracking System. Results revealed existence of primary olfactory repellent effect of MA against house rat (R. rattus). Histomorphological studies of tongue revealed sloughing of filiform and fungiform papillae, degeneration of keratin layer, mild hyperkeratosis and dysplasia, exophytic hyperplasia of epithelial layer of tongue. In case of nasal tissue, change in shape of maxilloturbinates and nasoturbinates, loss of cilia, degeneration of goblet cells and decrease in thickness of epithelial layer of nasal septum was recorded. Results again revealed existence of olfactory and gustatory repellent effect of MA. Application of MA based formulations (F1-F6) prepared using mixture of different oils, photostabilizers and stickers on wheat bags under simulated storage conditions in breeding cages and in experimental rattery revealed that formulation F2 was more effective. Application of effective formulation F2 along with different delivery systems (wood waste (WW), maize cobs (MC) and wheat straw (WS)) under simulated storage conditions revealed that sprinkling of formulation F2+WW (Wood Waste) on wheat bags prevented rodent damage for upto 8-35 days under simulated storage conditions, grain stores and in ESIC hospital. Duration of prevention of rodent damage reduced under no-choice conditions and with increase in rodent infestation.en_US
