REPORT OF THE STATE ENTOMOLOGIST I918 49 



An examination of conditions near Niverville and Muitzeskill 

 June 13 th 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.
