FURTHER NOTES ON SOME ALTERNATIVE HOSTS OF THE ORIENTAL FRUIT MOTH PARASITE, GLYPTA RUFISCUTELLARIS CRESS

Extract

In 1935, the writer published a preliminary paper on some alternative hosts of oriental fruit moth parasites, in which Glypta rufiscutellaris Cress. was recorded from an unknown leaf-tier on hawthorn in 1934. This species has since been identified by Dr. J. H. McDunnough as Epinotia sp., presumably laracana Kft. In the summer of 1935, G. rufiscutellaris was again reared from this host and an attempt was made to induce the emergents to parasitize oriental fruit moth larvae. Unfortunately, all but a single unfertilized female were destroyed by ants, but the survivor successfully parasitized newly hatched fruit moth larvae which were exposed in the cage on July 20 and 21, 12 male Glypta emerging from this material on August 19 to 25.
