The Mean

The efficacy of Bt maize MON 810-YieldGard<sup>&reg;</sup> and of Trichogramma wasp against European corn borer (ECB) (Ostrinia nubilalis H&uuml;bner) was evaluated in the period of 2002&ndash;2008 in field trials on three localities in the Czech Republic. The efficacy of Bt maize on the reduction of the number of tunnels caused by ECB per 100&nbsp;maize plants before harvest was always 100% and that in Trichogramma treatment was on average 50%. The mean increase of the yield of 15% and 10% was obtained in Bt maize and Trichogramma treatments, respectively in comparison with the untreated control. The damage curve and economic injury level by ECB on maize was developed for the evaluation of the yield losses and management of the pest control. The higher economic efficacy of growing Bt maize as compared to other control measures is documented.

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.
