Abstract:The vapor-heat method is adaptable for the treatment of narcissus bulbs for the control of bulb flies and mites. A two-hour period of treatment at 111. appears to be the minimum requirement for control of the larvae of the lesser bulb flies (Eumerus spp.) and of the greater narcissus fly (Merodon equestris Fab.). Control is also obtained of the two species of mites, Rhizoglyphus hyacinthi Bdv. and Tarsonemus approximatus var. narcissi Ewing, which are frequently found on narcissus. Bulbs treated at the optimum time during the dormant period were forced under glass and produced good flowers. Planting stock so treated is benefited through the more vigorous growth caused thereby and an additional increase in weight in the resultant crop.
