Male Sex

AbstractEuropean corn borer males have hair pencils located ventrally on the 8th sternite and these are extruded when a male approaches a calling female. The fact that (i) antennectomized females mated significantly less than both intact controls and individuals subjected to other forms of surgery, and (ii) males with hair pencils removed had a significantly lower mating success than control males, suggests that a male pheromone is involved in the mating system of the European corn borer.

Experimental Plots

In late August, 1957, a parasitized second-generation pupa of Pyrausta nubilalis (Hbn.) was observed in silks of an immature corn ear in the experimental plots at St. Jean. The pupa was incubated at 75°F. in a petri dish, and two weeks later an ichneumonid parasite emerged and was identified by Mr. G. S. Walley, Entomology Division, Ottawa, as Scambus pterophori (Ashm.). Asecond generation of P. nubilalis is very unusual in the St. Jean area. This is apparently the first record of this ichneumonid as a parasite of P. nubilalis in Canada.
