Antiinflammatory and antidiarrhoeal ( Singh and Pandey, 1996 Singh et al., 1996 Srinivasan et al., 2001), antidiarrhoeal ( Shoba and Thomas, 2001 Brijesh et al., 2006), antimalarial ( Misra et al., 1991), antibacterial ( Patel and Trivedi, 1962 Biswal et al., 2011), wound healing ( Subramanian and Nagarajan, 1988), anticancer ( Arulvasu et al., 2012), anthelmintic ( Nirmal et al., 2007) and analgesic ( Ganesh et al., 2008) activities of the plant were previously reported. (Papilionaceae) (Synonym leaf gall, Pongamia pinnata) which may also be called as Galdupa indica, is a large tree found in tropical regions and coastal forests of India, North Australia, Southeast Asia and Malaysia ( Krishnamurthy, 1969 Satyavati et al., 1987). The use of extracts from various plants is being explored as an alternative to chemical acaricides because they are potentially less toxic to the animals and safer for the environment. Their indiscriminate and repeated use has already resulted in problems related to environmental pollution, milk/meat contamination and the development of resistance in target species along with a subsequent increase in cost ( Dipeolu and Ndungu, 1991 Jonsson and Piper, 2007). T ick control throughout the world is based mainly on the use of chemical acaricides.
