of nurseries ami of iiiiiiortcd nursery stock is first briefly reported upon. Dur- 

 ing the year 224 boxes and packages imported from France were inspected. 

 One lot of 13 boxes was found to be infested with 't2 winter nests of the brown- 

 tail moth, a few on pear and quince, but mostly on apple and dwarf apple 

 stock. A bill providing for the inspection of apiaries to suppress contagious 

 diseases of bees, which was passed in 1900, is briefly discussed, as is the 

 municipal spraying of elm trees in Connecticut during 1909, and the work against 

 the gipsy moth. During the winter of 190S-9 but 6 egg masses of the gipsy moth 

 were destroyed at Stonington and but 98 caterpillars during the summer of 1909. 

 In December. 1909, a colony of gipsy moths was discovered at Wallingford, of 

 which up to March 1, 1910, 7,500 egg clusters had been destroyed. 



Summarized accounts of the rosy apple aphis {Aphis sorbi), bud moth, leopard 

 moth, and peach borer, including references to the literature, are presented. 

 During 1909 the rosy apple aphis was a source of considerable injury to apple 

 trees. Its eggs hatch about the middle of April just as the green leaves begin 

 to show at the ends of the buds. In 1909 they were abundant through blossom- 

 ing time and wei'e thick on the young fruit. During the latter pai't of June or 

 about July 1 they disappeared entirely from the trees and did not return again 

 until October. On November 12, 1909, the aphids were laying eggs, though 

 but few could l)e found. Efforts were made during the summer to discover its 

 intermediate host plant, but without success. Technical descriptions of its 

 several stages, prepared by A. I. Bourne, accompany the account. Mcgorismus 

 flctcheri was its most important parasite in Connecticut. During the past two 

 or three seasons the bud moth seriously Injured apple trees in certain portions 

 of the State, particularly at Stonington. Observations made following the use 

 of arsenate of lead (1 lb. to 10 gal. of water) at that place for the gipsy moth 

 indicate that this poison will also control the bud moth. Considerable evidence 

 of serious damage by the leoi)ard moth to shade trees, particularly elms, came 

 to the author's attention. Next to the San Jose scale, the peach borer is thought 

 to be the most serious insect enemy of the peach in Connecticut. Brief mention 

 is made of mosquito bi'eeding areas examined at the request of health officei's. 

 B. H. Walden reports upon the fumigation of several buildings with hydro- 

 cyanic-acid gas. 



Under the heading of miscellaneous insect notes, mention is made of the 

 tobacco bud worm (ClilorUlra vircscais) which was found feeding upon experi- 

 mental tobacco plants growing on the station grounds; of cankerworms which 

 were the source of much damage locally to orchard and shade trees throughout 

 the State; of the greenhouse leaf tyer {Phlyctwnla fcrrwjalis) which injured 

 gi-eenhouse cinerarias and daisies at New Haven by devouring the leaves; of 

 the strawberry crown girdler {Otiorhynchus ovaiiis) which destroyed young 

 hemlock trees in a New Haven nursery; of white grubs in grass lands; of 

 white ants {Ternics flavipes) which injured a dwelling house in South Nor- 

 walk; and of the green rose chafer [Euphoria [Cctonia] aurata) which was 

 found in the j)acking from nursery stock imported from Europe. 



Injurious insects and remedies, C. J. S. Bethune {Ann. Rpt. Ontario Agr. 

 Col. and E.rpt. Farm, 35 (IVOD). pp. 27-3.'i). — During the year aphids attacked 

 nearly every cultivated plant and many fruit and shade trees. The European 

 elm scale was very abundant in the northern part of the city of Toronto and 

 the cottony maple-scale also appeared in certain sections of that city. Other 

 insects the occurrence of which is noted are the boll or corn ear worm and 

 the carrot rust fly {Psila rosa'). 



Experiments were conducted by T. D. Jarvis in which Vanco brand arsenate 

 of lead. 2 lbs. to 40 gal. of water, was applied at a pressure of 200 lbs. in a 

 6-aci-e orchard of Greenings and a 10-acre orchai'd of Baldwins. The first
