 The study was conducted to determine the specific chemical constituents of cattle urine and indigenous plant extracts. Chemical analysis revealed that the specific chemical composition i.e., chloride, sulphate, nitrite and phosphorus pentaoxide contents of fresh and fermented cattle urine were 1556, 364, 2.0, 26.8 and 4514, 252, 22.4, 7.49 mg l-1, respectively. The proximate chemical compositions of neem seed kernel extracts, mahagoni seed extracts and allamanda leaves extracts were analyzed and it was found to contain chloride (144, 55.4, 141 mg l-1), sulphate (51.1, 5.03, ˂4.0 mg l-1), nitrite (˂1.0, ˂1.0, ˂1.0 mg l-1) and phosphorus pentaoxide (413, 410, 49.5 mg l-1), respectively. Chloride and nitrite in fermented cattle urine (4514 and 22.4 mg l-1) was found extremely higher than in fresh cattle urine (1556 and 2.0 mg l-1). There was numerically higher difference in sulphate and phosphorus pentaoxide concentrations in fresh cattle urine (364, 26.8 mg l-1) compared to fermented cattle urine (252, 7.49 mg l-1).These results revealed that indigenous plant extracts of neem seed kernel, mahagoni seed and allamanda leaves contents chloride, sulphate and nitrite were extremely lower than in both fresh and fermented cattle urine but there were great difference in phosphorus pentaoxide concentration (413, 410, 49.5 mg l-1) in both fresh and fermented cattle urine (26.8, 7.49 mg l-1) composition. It was evident from this study that as the fermented cattle urine contained higher concentration of chloride and nitrite can be considered as a good means of insect pest management.

Three field experiments were conducted to find out the efficacy of neem products against the damage of rhinoceros beetle to coconut palm and termite damage to coconut palm and plaited leaves. The application of cither neem seed powder + sand (1:2) or neem seed kernel powder + sand (1:2) @ 150 g mixture per palm in the bases of three leaf axils in the crown, were found more effective against rhinoceros damage. Spraying of neem oil 5% or neem seed kernel extract 20% from the base and up to, 2 m height on the truck protected the palm from termites. Spraying with copper sulphate 1% and‑then neem oil 5% or copper sulphate 1% and then neem seed kernel extract 20% on plaited coconut leaves was found efficacious in protecting plaited coconut leaves for more than six months even when the plaited leaves were kept on the bare ground having persistent live termite colony throughout the year.
