Sherman (F.). Observations on Natural Enemies of the Fall Canker- 

 worm {Ahophila pometaria, Peek) in Forests of Southern 

 Alleghany Mountains, in 1920.^ — Jl. Econ. Ent., Geneva, N. Y., 

 xiv, no. 6, December 1921, pp. 478-481. 

 As a result of repeated injury by Alsophila pometaria, Peck (fall 

 canker-worm) in certain limited areas of wild mountain forests in 

 western North Carolina during 1917-19, it was decided to make a 

 study of its natural enemies. Among those recorded are fifteen birds 

 and the following predacious insects : the Carabids, Calosoma frigidum, 

 Kirby, and C. scrutator, Say, the Pentatomid, Podisus modestus, Dall., 

 the Capsid, Lygus sp., black ants, and Panorpa sp. The parasitic 

 insects are Telenonius sp., Euplectrus sp., and a Tachinid, Sarcophaga 

 cimhicis or 5. latisterna — the exact species could not be determined, 

 as only a female was reared. Six species of Tachinids, of which Masker a 

 eiifitchiae, Twns., was common, and four Ichneumonids, Amblyteles 

 spp., were also collected and may be parasitic on Alsophila pometaria. 

 It was apparentl}^ due to the action of these parasitic and predacious 

 enemies, especially C. frigidum, Telenomus, and P. modestus, that the 

 damage caused by A. pometaria in 1920 was less serious than during 

 the previous years.

 the Sugar Cane Moth Borer : a Comparison.— J/. Econ. Ent., 

 Geneva, N.Y., xiv, no. 6, December 1921, pp. 481-485. 



The existing information on Pyrausta nubilalis, Hb. (European 

 corn-borer) and Diatraea saccharalis crambidoides, Grote (sugar-cane 

 moth borer) is collated in such a form as to be readily available 

 for comparison [cf. R.A.E., A, vii, 407, 411, etc.]. As a result of 

 these comparisons it is thought that P. nubilalis, if introduced into 

 the Southern States, would become even more injurious than it has 

 been in the north.

 Army-worm in Southeast Missouri. — //. Econ. Ent., Geneva,

This paper is compiled by the junior author from notes left by the 

 late V. King, to whom the remedial measures described are entirely 

 due. 



The predatory enemies and parasites of Cirphis {Heliophila) uni- 

 puncia (army worm) were very numerous in 1914, and included a 

 bird, Dolichonyx oryxivorus, the Carabids, Calosoma scrutator, C. 

 lugubre and C. calidum, the Tachinids, Winthemia quatiiorpustulata 

 and Frontina aletiae, and a Braconid, Apanteles militaris. The two- 

 furrow plan without post holes is considered to be the most satisfactory 

 method of creating a barrier against this pest in heavy soil ; on very 

 light soil, ditches with post holes at every fourteen feet may be 

 em.ployed. The method of constructing and maintaining such ditches 

 is described.

The remedial measures advocated against the grape berry moth 



[Polychrosis viteana, Clem.] have generally been based on the poisoning 



of the larvae, but, as a result of the observations here described, it
