Toxicity of Biopesticide Datura Innoxia against the Mortality of Holotrichia Serrata (Fab) Adults

White grubs are the larvae of Scarabaeidae beetles. The white grub is a major pest problem in India as well abroad also. White grubs are pests of national importance in India and are a serious constraint to production of Kharif crops. White grub is caused heavy damage to the agricultural commercial crops and wide variety of host plants like neem, babhul, ber, khair.

The Holotrichia serrata is prevalent in Karnataka, Maharashtra, Andhra Pradesh, Tamil Nadu, Kerala, South Rajasthan, Tarai belt of Uttar Pradesh and South Bihar. In the present study, aqueous seed extract of different concentrations treatment against the mortality of Holotrichia serrata. The seed extract of Datura innoxia (Mill) at 10, 15, 20, 25 and 30g/ 100ml concentrations were incorporated; 20% or 20g/100ml concentration shows 50% mortality agaist Holotrichia serrata (Fab) adults after 96 hours explosion.
