value of jarring and of spraying tlie trees to protect the fruit from 

 the curculio. One half of the trees were jarred, this treatment being 

 given lo times, beginning on May 15 and continuing for 3 weeks. The 

 other half of the orchard was given 3 si^rayiugs with a mixture of 

 Paris green and lime in water. Three times as much foliage aud fruit 

 <lropped from the sprayed trees as from those that were jarred, but 

 the opinion is held that spraying with arsenites is the most economical 

 method of treatment. Two apricot trees were sprayed 3 times with 

 Paris green to protect against the curculio, with beneficial results, 

 although the fruit was severely injured by a fungus which attacked it 

 when nearly ripe. 



Descriptive, life history, aud remedial notes are given on the elm- 

 leaf beetle {Galeruca xanthomelwna), strawberry weevil {Anthonomus 

 signaiu-s), wheat-head army worm {Leucania albilinea), and strawberry- 

 root aphis {Aphis forhesi), which proved destructive in the State. The 

 strawberry-root aphis was especially prevalent aud injurious in the 

 neighborhood of Felton, but yielded to treatment with bisulphid of car- 

 bon, though the remedy is too expensive to be generally recommended. 



Report of the entomologist, J. B. Smith {N^ew Jersey Stas. Rpt, 

 1893, pp. 439-603, figs. 197). 



Synopsis. — This report contains a general review of the work accomplished during 

 the year, brief remarks on special insect outbreaks, and more extensive notes 

 upon Die pear midge, pear-tree psylla, wheat-head army worm, strawberry weevil, 

 corn-root web worms, pale-stiiped Ilea beetle, and chestnut weevils. The bulk 

 of the rejjort is taken up by a more or less popular paper on the chief beneficial 

 insects. 



General revieiv (pp. 439-453). — Notes on the routine work of the office, 

 with special remarks on several injurious insects, particularly the sweet- 

 potato flea beetle, melon louse, onion maggot, wheat-head army worm, 

 pale-striped flea beetle, strawberry weevil, pear midge, anew asparagus 

 beetle, and some cranberry insects. The entomological inquiries and 

 information that were published throngh the summer in the crop bulle- 

 tins are quoted. 



Pear midge (pp. 453-4G0). — Notes on the life history and devastations 

 of Diplosis jjyrivora, and experiments with treatment for it, which have 

 been given in previous publications of the station. 



Pear-tree psylla (pp. 4G0-4G5). — General life-history notes for Psylla 

 pyricola. Scraping off" the rough bark of the infested trees and wash- 

 ing the trunks and larger branches with a solution of whale-oil soap iu 

 the winter, and in the spring si)rayiug the trees with kerosene emulsion 

 is recommended. 



Wheat-head army worm (pp. 4G5-469). — Kotes on the unexpected 

 appearance of Leucania albilinea, its life history, and remedies. The 

 larvse appeared early in July, causing considerable damage to ripening 

 wheat. Later in the season the insects vanished, and are supposed to 

 have returned to their normal food plants, the wild grasses. Plowing
