Observations on Epichorista ionephela
Tidsskr Planteavl 69(2): 293-298
Epichorista ionephela, a South African tortrix moth, was 1st found in Denmark on carnations in 1960. Studies have indicated that a generation of the moth is completed in about 2 mo. at 18-20[degree]C. The different developmental stages are described, and some characteristic differences are shown between this and Tortrix pronubana. Cooling the plants to 0[degree] C for 10 days kills about half of the larvae and pupae. All stages of larvae are killed by fumigation with methyl bromide in vacuum, but the cuttings could only tolerate a small concentration.
