The injuriousness and control (with pyrethroids and formulations of Bacillus thuringiensis var. thuringiensis) of Ostrinia nubilalis (Hb.) were investigated on sweet maize in France in 1982 and 1983. In 10 trials in 1982 when the estimated economic threshold of 0.8-1.2 larvae/plant was exceeded, the gains in yield after treatment were 2.4, 33 and 44 q for infestations of 0.9, 4.6 and 3.1 larvae/plant, respectively.
