     The apple crop raiding by rhesus monkeys (Macaca mulatta) is a serious issue among apple growers in Himachal Pradesh, India. The primate research division of the Conservation Himalayas studied rhesus crop raiding behavior in Narkanda and Thanedhar villages of Himachal Pradesh from January through August, 2017. The study area was divided into 10 grids of forest fringe apple orchards. One rhesus group was observed in each village study site. The rhesus crop raiding events (r-CREs) were recorded using one crop raiding behavior checklist. The results indicated that the r-CREs were more frequent during the fruiting season (average 127 r-CREs/day) than in the budding (average 67 r-CREs/day), blossoming (average 32 r-CREs/day), and harvesting (average 21 r-CREs/day) seasons. During the apple fruiting season, the r-CREs were more frequent (n=11 times/per session) in the morning than in the afternoon (n=4 times/per session) and evening times (n=2 times/per session). Adult females were found to be more frequent apple crop raiders (average 40% time budget/day) than adult males (average 30% time budget/day), juveniles (average 30% time budget/day) and infants (0% time budget/day). The r-CREs accounted for 45% in tree branch breaking, 40% in fruit eating, 10% in stem damaging and 5% in blossom eating. This result is an indicative of threats to apple growers and demands for scientific research on the rhesus population dynamics from the perspective of population management.
