Azalea growth in response to azalea lace bug (Heteroptera: Tingidae) feeding.
The effects of azalea lace bug, Stephanitis pyrioides (Scott), feeding injury on azalea growth and development were investigated using 'Girard's Rose' azaleas during a 2-yr field study in Georgia Low, medium, and high injury treatments, which corresponded to 6, 8, and 14% maximum canopy area injury, were compared with control azaleas that received no lace bug infestation. Flower number, whole-s...
متن کاملSupercooling in overwintering azalea flower buds.
Differential thermal analysis and nuclear magnetic resonance spectroscopy experiments on whole flower buds and excised floral primordia of azalea (Rhododendron kosterianum, Schneid.) proved that supercooling is the mode of freezing resistance (avoidance) of azalea flower primordia. Increase in the linewidth of nuclear magnetic resonance spectra for water upon thawing supports the view that inju...
متن کاملFeeding Injury of the Azalea Lace Bug (Heteroptera: Tingidae)1
J. Entomol. Sci. 35(3): 213-219 (July 2000) Abstract Azalea lace bug, Stephanitis pyrioides (Scott), feeding rates were investigated in controlled laboratory bioassays. Individual newly-eclosed nymphs were transferred to cut stems of 'Girard's Rose' azaleas and maintained at either 20°C for 26°C for the duration of their lifetimes. Feeding rates, determined using computer assisted image area an...
متن کاملAnthracnose on Azalea and Its Control in Production Nurseries
Anthracnose, which is caused by the fungus Colletotrichium gloeosporides, is a widespread and destructive disease on container-grown azalea. This disease is especially common in container nurseries, which are located near the Gulf of Mexico in Florida, Alabama, Mississippi, Louisiana, and Texas. Anthracnose is a hot, wet weather disease. This year, frequent showers and daily cloud cover through...
متن کاملPhytophthora foliorum sp. nov., a new species causing leaf blight of azalea.
A previously unknown Phytophthora was recovered more than 60 times from evergreen hybrid azalea leaves collected during surveys for the sudden oak death pathogen Phytophthora ramorum in California and Tennessee. The novel Phytophthora was discovered when genomic DNA from this species cross-reacted with the ITS-based diagnostic PCR primers used to screen plants for the presence of P. ramorum. Th...
