The coconut Rhinoceros beetle (Oryctes rhinoceros) is one of the most damaging insect to coconut palms in India. The experimental study on the growth response of 3 instar larvae of Oryctes rhinoceros infesting the coconut trees. The LC50/96 hours value for the larvae of Oryctes rhinoceros were 29.5% for neem cake powder, 24.5% for neem oil and 14.9% for distillery effluent respectively. In the ...

the date palm fruit stalk borer is one of the most important pests of date palm in the world. biochemical properties of digestive proteases in oryctes elegans prell larvae were investigated in this research and optimal total proteolytic and trypsin activities were obtained at ph 9.0 and 11.0, respectively. activity staining of protease on sds-page showed one isoform. also, zymogram pattern of t...
