oa Journal of the Entomological Society of Southern Africa - Experiments on sterilization of the Snout-Beetles, Philyctinus callosus Boh. and Eremnus setulosus Boh., on export grapes in cold-storage
The presence of live adult snout-beetles, Phlyctinus callosus Boh., in South African export grapes reported by quarantine authorities in New York (Kriegler, 1957), necessitated fumigation before distribution, thus adding to costs and detracting from the shelf-life and economic value of the fruit. Another serious aspect of this and subsequent discoveries is the threat to expansion of the export market for grapes unless, of course, some satisfactory sterilization procedure could be evolved.
