The species composition and seasonal incidence of ticks on two species of monkeys ( and ) occurring in the Kyasanur Forest disease (KFD) epizootic area of Shimoga District, Mysore State, India, are presented.

The bulk of the ticks were larvae or nymphs even though a substantial number of monkeys were examined during the monsoon when adults are prevalent on vegetation in the forest. The dominant genus of ticks on monkeys was and the commonest species, , from which KFD virus has repeatedly been isolated. Altogether, 9 of the 14 species of known from the area were found on monkeys. Other genera taken were and .

There was a wide seasonal variation in the infestation rate of monkeys, with a peak in November when ticks (predominantly larvae) were found on almost all monkeys, and a period during the monsoon from June to September when ticks were rare or absent on monkeys.

In a series of monkeys collected in approximately equal numbers in each month of the year, mixed infestations of larvae and nymphs were found on individual hosts during November, December and January.
