THE INSECT RECORD FOR I9O2 77 



the first indications that pear growers, who suffered from this 

 pest in 1891, had of its presence, was the noticeably lessened 

 vitality of their trees early in the season. Old trees, especial- 

 ly, put forth but little new growth. Where new growth started, 

 in many cases the shoots began to droop and wither in May, 

 as if from a loss of sap. A little later whole trees put on a 

 sickly appearance ; the leaves turned yellow and the fruit 

 grew but little. By midsummer nearly all the leaves and half- 

 formed fruit fell from many trees." 



This insect may be destroyed by spraying in spring, after 

 the eggs hatch and before the first brood matures, with 

 kerosene emulsion diluted with twenty-five parts of water. 

 This is a simple and satisfactory remedy ; if applied soon af- 

 ter a shower has washed off much of the honeydew, it is more 

 effective. 



Among the other insects reported as present in New Hamp- 

 shire during the season, mention may be made of the follow- 

 ing: The White-marked Tussock Moth 1 continued pres- 

 ent on the shade trees of towns and cities, having attracted 

 especial attention in Nashua and Manchester. The cocoons 

 of the Cecropia Emperor Moth, 2 one of which is illustrated 

 herewith, were brought to my notice several times. This in- 

 teresting insect is of special value for use in nature work in 

 the schools. A brief account of its life-history will be found 

 in Bulletin 59 of this station. The more beautiful Luna 

 Moth 3 was also brought in as an adult several times. Its life- 

 history is also discussed in the same bulletin. The Imported 

 Currant Worm 4 was about as destructive as usual, being 

 easily held in check by spraying or dusting with poison. 

 The presence of the Fruit Bark-Beetle 5 was noted in 

 Nashua, its attack apparently being confined to a dead apple 

 tree. The Plum Curculio 6 was very injurious in plum or- 

 chards, although its injuries to apples were less in evidence 

 than usual, presumably because of the abundant crop. Wire- 

 worms and cutworms of various species were also locally 

 quite destructive.
