Frond injection method, a novel approach of insecticide administration into the coconut palm wasapplied using an eco-friendly and animal origin insecticide cartap hydrochloride (50% SP) against Opisina arenosellaWalker. The results on absorption showed that all the dilutions of cartap hydrochloride (50% SP) injected to frondswere absorbed completely within 24 h and recorded 100 % larval mortality, 7 days after imposing injection and foundsuperior over control.
