dooryard trees all over the State were overrun by the psyllas. It was 

 the most general infestation that has occurred in New York. Except 

 the San Jose scale, this psylla is the most destructive insect pest of 

 the pear. Its ravages seem to be increasing in New York, and it has 

 come to be nearly as standard a pest as the codling moth or plum 

 curculio. Only the most thorough work with an oil or soap spray 

 (whale-oil soap, 1 pound in 5 to 7 gallons water, kerosene emulsion 

 diluted with 7 to 10 parts water, or an oil and water spraj' of 10 to 15 

 per cent of oil) will control the psjdla. Some orchardists with very 

 tall standard trees are now discouraged after lighting the pest nearly 

 every year for ten years. Prompt and thorough work early in the 

 season is necessary in fighting the psylla. 



SNAILS OR "SLUGS." 



Large numbers of small shell-less snails or "slugs" ravaged young 

 corn, beans, and tobacco plants in central New York in June. In one 

 case 10 acres of beans were badly injured, the "slugs" riddling the 

 leaves and eating into the stalks. Doubtless the wet season of 1902 

 was very favorable for the development of these moisture-loving ani- 

 mals. A dry spell in July checked their ravages and prevented the 

 carrying out of some experiments we had planned. Some hand-picked 

 them at night, and a strip of salt kept outsiders from getting into a 

 bed of seedling tobacco. Doubtless a poison spray or dust will check 

 these "slugs." 



THE ROSE-CHAFER. 



There are several very sandy spots in New York where rose-chafers 

 breed and swarm onto near-b} r strawberry beds, vine3 r ards, and cherry 

 and apple orchards. The beetles appear in these limited areas every 

 year, but they were unusually numerous in 1903. We are convinced 

 that much can be done to check this pest by thorough and timely cul- 

 tivation of their breeding grounds when they are in the pupa state in 

 May. Grape-root- worm pupae and wireworm pupa3 are easily killed 

 in this way, and why not rose-chafer pupge also? We shall try very 

 strong doses of arsenate of lead in the menu of the beetles in 1904 if 

 they again appear in destructive numbers. 



THE APPLE BUCCULATRIX. 



This little pest has again swung into its "up " or destructive period 

 in New York, and last season the foliage in several apple orchards in 

 central New York were badly skeletonized by the tiny caterpillars. 

 A bulletin will soon be issued from the Cornell experiment station on 

 this insect. We have observed several new and interesting phases of 

 its life, and were able to get a series of photographs of the heretofore 

 unobserved process of the making of the cocoon. The common name 

 now in use for this insect has long been a stumbling-block to us, and
