STUDIES ON THE GC MASS AND HPLC ANALYSIS IN THE DEFENCE SECRETION OF CARABIDAE BEETLE PHEROPSOPHUS HILARIS

The bombardier beetle Pheropsophus hilaris having a pair of defensive organs consisted of many small synthetic lobes, large reservoirs and collecting ducts. The defence secretary lobes of P. hilaris secrete aqueous hydrogen peroxide and hydroquinones, which are stored in the large quantity in the collecting reservoirs. The modern research is oriented towards attaining health and economic benefits of mankind. Now- a- days, the farmers are using large number of pesticides and insecticides to control the pest and insect. The poor knowledge among the farmers is the main reason for pollution. In order to reduce pollution by contaminating the amount of pesticides, biological control is also advocated and attempted on different scale. In recent years, in addition to bio control, bio pesticides came into existence for integrated pest management. In view of this, it has been programmed to study the GC MASS and HPLC analysis of the defence secretion of P. hilaris
