REPORT OF THE STATE ENTOMOLOGIST 1918 49 
An examination of conditions near Niverville and Muitzeskill 
June 13th disclosed a rather general prevalence of the insect and 
resulted in locating two fields near Niverville where nearly 30 per 
cent of the heads were infested, a considerable proportion of these 
being white heads and empty or nearly so. In addition, there were 
numerous other heads apparently normal which showed a yellowish 
cast through the glumes and on examination several to a number of 
the grains were dwarfed or blasted by one to three or four maggots. 
One head from Niverville with 28 spikelets contained 9 larvae, a 
second with 22 spikelets 35 larvae, and a third with 23 spikelets 
21 larvae. 
An examination of conditions in and about Nassau showed a 
somewhat general prevalence of wheat midge, certain fields probably 
having 10 to 12 per cent of the heads infested while a number of 
others were almost free from the insect. A closer examination of 
one field showed the maggots to be uniformly present throughout, 
indicating in this instance at least very little or no connection 
between infestation and the proximity of strips of grass or grassy 
areas. One of the most serious infestations came to notice through 
N. G. Farber, Rensselaer county farm bureau agent, who sent in 
one head, superficially not badly affected, that contained 62 maggots. 
Representative lots from three fields, two in East Schodack and 
one in North Chatham, were carefully examined and the results are 
tabulated below.
