摘要:
Life cycle studies showed that anthurium thrips,Chaetanaphothrips orchidii(Moulton) developed from egg to adult in 27.4 days. Studies confirmed that second‐instar nymphs migrated off the host plant and pupated in the media below. Insecticide granules wereveryeffective in decreasing thrips‐injured flowers for 5 months. Aldicarb 10G and disulfoton 15G were most effective, followed by chlorpyrifos 2G and oxamyl 10G, respectively. As foliar sprays, bifenthrin 10W.P, cyfluthrin 2.0E.C and chlorpyrifos 1.0M.E were also effective in reducing thrips‐injured flowers; however, control did not persist after the last insecticide application. This study suggests the use of granular insecticides at 5‐month intervals or foliar sprays at 2‐week intervals to reduce anthurium thrips below economic injury levels in a pest management strategy.
