Abstract

Different formulations of pesticides were applied to the base of inter-space of leaf sheath
of the top-most three leaves in the crown of 42-month-old coconut seedlings to provide
protection against attacks of rhinoceros beetle. Application of naphthalene balls (weighing 3.5
g each) at the rate of three balls per palm, one each to the base of three top-most leaf sheath, at
45-day intervals was found give 100% protection against the pest attacks. The repellant action
of naphthalene was significantly superior to that given by conventional insecticides such as
HCH 10%, Carbofuran or Phorate.
