With Further Notes on the Pyralid Moth Borer of Cane. 15 
Control. 
By adopting remedial measures: against these moth-borers would 
it be possible to secure heavier ratoon crops in certain localities 2 The 
question presents rather a nice point for investigation, although at 
present the writer is not in a position to advance definite recommendations 
in this connection. 
River flats liable to flooding seem to suffer more than high land, 
owing, perhaps, to a comparative scarcity in some such situations of 
small predaceous insect enemies. The severity of the infestation at 
Pyramid, tabulated above, may serve to illustrate this point, as during 
a rather prolonged examination of these affected ratoons I did not once 
meet with a single specimen of Pheidole megacephala, although this 
voracious ant usually occurs freely in lands of volcanic origin around 
Gordonvale, where it does useful work in subduing certain cane pests. * 
The practice adopted some years ago in parts of America of “‘shaving”’ 
cane stools directly after harvesting a crop in order to remove damaged 
buds situated above ground and force out the lower eyes, might be found 
beneficial in the present instance, since it would materially reduce the per- 
centage of suckers springing from buds exposed to direct sunlight.
