Onion Maggots, BY John B. Smith, Entomologist. Fourteenth An- 

 nual Report, page 441. 



'•Quite early in the year Mr. Theo. F. Baker, of Bridgeton, wrote 

 that the maggots had suddenly made their appearance in his land in 

 very large numbers, and he asked for suggestions. This was rather 

 a surprise to me, because Mr. Baker had stated positively during the 

 preceding winter that no trace of the onion maggot had been here- 

 tofore seen on his land. He repeated this statement and added that 

 he has known the insect from other localities and felt positive that 

 this was the first appearance in his fields. Nor did any of his neigh- 

 bors seem to have known of it until the present season. The appear- 

 ance in such numbers, therefore, was a matter of some surprise. For- 

 tunately, the growers of onions in that immediate vicinity were fully 

 alive to the consequence that might result from the increase of the 

 insect, and they at once adopted heroic measures. The entire fields 

 were gone over, row by row, and all plants that showed signs of infec- 

 tion were taken out bodily and afterwards destroyed. Then heavy 

 dressings of kainit were applied, with the result that no further traces 

 of these maggots were seep at any time in the season." 

 Pear Midge, by John B. Smith, Entomologist. Fourteenth Annual 

 Report, page 444. 

 "At my suggestion, Mr. J. M. White, of New Brunswick, whose 

 orchard became infested last season, applied a very heavy top-dressing 

 of kainit (1000 lbs. per acre) under the infested trees, with the result 

 that this year his orchard was practically free from the midge, while 

 in the neighboring orchard, which was also infested last year, and 

 where no measures of any kind had been taken, every Lawrence pear 

 was destroyed, while many of the Bartletts were also attacked." 

 Pear Midge, by John B. Smith, Entomologist. Fourteenth Annual 

 Report, page 455. Experiments were made to confirm the experience 

 gained in the practice of testing the effect of fertilizers against pear 

 midge. 



"From Mr. White's experience, and from the results of the ex- 

 periments above detailed, I feel justified in concluding that we have 

 in kainit, used rather heavy in fertilizing quantity, an efficient remedy 

 for this insect. The application should be made under the trees as a 

 top-dressing at any time after the midge larvae have left the infested 

 fruit. This means any time in the latter part of June, or somewhat
