dc.description.abstract Control of the orchid weevil, Orchidophilus aterrimus (Waierhouse) with acephate 75SP, bendiocarb 76WP, chlorpyrifos 2.0EC, and microencapsulated methyl parathion 2.0F significantly increased the number of marketable flowers of Vanda "Miss Joaquim" and decreased the number of unmarketable, white streaked flowers. The significant reduction in larval infestations, adult feeding injury and the rate of white streaked flowers in insecticide-treated vanda plants suggests that orchid weevil infestation and/or injury may be responsible for white streaked flowers. The relatively long life cycle of 144 days and the toxicity of tested insecticides to only the adult stage of the orchid weevil were probably reasons which made it necessary to apply 6 spray applications before a severe infestation (> 14 weevils per week) was reduced to a minimum level (<4 weevils per week) in Vanda "Miss Joaquim." en_US
