HOST: ANTHURIUM, Anthurium andraeanum Andre cv. 'UH 1060' and ‘Ozaki’
TARGETED PEST: Anthurium Whitefly: Aleurotulus anthuricola Nakahara


EXPERIMENTAL PROCEDURE
Bioassay tests were conducted from 15 Nov to 20 Dec 1991 on established plants 'UH 1060' and 'Ozaki' growing in volcanic cinder media in 7.6 liter bags under a fiberglass greenhouse. Treatments consisted of four blocks with 10 potted plants per block arranged in a randomized complete block (RCB). Blocks 1 and 3 consisted of 'UH 1060' and blocks 2 and 4 consisted of 'Ozaki' cultivar. Tests began when a 100 percent infestation occurred in all blocks. NTN 0.5%G was applied once and watered after application. Five weeks after treatment ten scale leaves were sampled from each block and examined under a dissecting microscope for live and dead adults, pupae, nymphs and eggs. The number of live adult, pupae, nymphs, and eggs from ten scale leaves were pooled for analysis.

RESULTS
NTN 0.5%G significantly reduced all life stages of the whitefly and was nonphytotoxic to flowers or foliage.
