 CHRYSALIDS OF GIPSY-MOTHS WHICH HAVE BEEN DESTROYED BY PARASITES, PROBABLY 



Calosoma sycophanta (SEE page 53 and text, page 66) 



their ravages are concerned, with the ad- 

 ditional damage which the brown-tail 

 moth does to summer resorts by virtue 

 of the irritating rash produced on the 

 skin of persons in its neighborhood by 

 the hairs from the caterpillars.

But there has been some spread. The 

 area now occupied by the brown-tail moth 

 has been enlarged enormously toward 

 the north and the east. The gipsy-moth 

 has spread much more slowly, but still 

 rather steadily, in practically all direc- 

 tions, though more to the north and east. 



Four sporadic outbreaks of the gipsy- 

 moth have been found outside of the reg- 

 ularly infested territory — two in Con- 

 necticut, one at Geneva, N. Y., and the 

 fourth (only discovered in January, 1914) 

 in the vicinity of Cleveland, Ohio. The 

 New York outbreak has been stamped 

 out ; the Cleveland outbreak will probably 

 be stamped out this year ; those in Con- 

 necticut are thoroughly under control, will 

 not be permitted to spread, and with some 

 certainty will be annihilated. 



We have referred to the conditions 



within the infested region as having im- 

 proved. This has been due to actual ex- 

 terminative work in the destruction of 

 the egg-clusters of the gipsy-moth, in the 

 burning of the winter nests of the brown- 

 tail, in the destruction of the gipsy-moth 

 caterpillars by spraying,' by collecting 

 them under burlap bands on tree trunks, 

 where they are subsequently crushed, and 

 by the general cleaning up of roadsides 

 throughout the region. 



A number of species of the imported 

 natural enemies (see pages 51 and 53) 

 have accommodated themselves to New 

 England conditions, have increased and 

 spread, and during the past year probably 

 destroyed more than 50 per cent of the 

 gipsy-moths and brown-tail moths which 

 hatched in the central New England re- 

 gion. Moreover, a disease has attacked 

 the gipsy-moth caterpillars, and another 

 those of the brown-tail moth, and these 

 diseases are apparently becoming more 

 widespread and virulent.
