TWO CATERPILLARS THAT HAVE 

 TROUBLED FLORISTS. 



A fern-destroying caterpillar Is de- 

 scribed in a new bulletin (No. 125) 

 issued by the Government's Bureau of 

 Entomology. The pest comes from 

 Florida, and has made its appearance 

 in northern greenhouses, particularly 

 in the District of Columbia, Illinois, 

 and Ohio, having undoubtedly been in- 

 troduced there in importations from 

 Florida. 



The caterpillar has the same habit 

 as cut worms, of cutting or severing 

 portions of the fern plant, apparently 

 destroying more than it needs for food. 

 As it is always warm in the green- 

 house where it works, the insect does 

 damage in winter as well as in sum- 

 mer. It attacks the tender leaves, 

 especially the growing tips of young 

 fronds, thus checking any attempt or 

 the plant to replenish its dying parts. 



The moth that lays the eggs from 

 which this caterpillar is hatched is sel- 

 dom seen by day. When aroused it 

 usually flies down under the benches. 

 Many moths are caught in spider webs 

 in dark corners of the greenhouses. 

 The color of the larvae varies from 

 yellow or bright green to nearly black. 

 Its length is about an inch and a half. 

 A cut in the bulletin illustrating both 

 moth and caterpillar will assist the 

 fern growers to identify it. 



The District of Columbia fern grow- 

 ers have experienced much trouble in 

 treating this pest. Finally, however, 

 the insect has yielded to the method of 

 hand-picking, which, although some- 

 what laborious, seems to be the most 

 efficacious way of overcoming it. 



Another caterpillar that attacks rose 

 bushes and young trees is described in 

 a new bulletin (No. 124) compiled by 

 the same entomologist. Hand-picking 

 is advised to control the ravages of 

 this insect in case its work has not 

 been too extensive, precaution being 

 taken to use a glove to avoid being 

 "stung," Bushes or trees may be 

 spraved with Paris green or arsenate 

 of lead if th'^re is no danger of poison- 

 ing h"man beinss therebv. 



It is onlv within recent years that 

 this slug-like caternillar has been 

 known to iniure roses. It has also 

 been remarked that the larvae feed on 

 wild cherrv. oak. chestnut, hickory, 

 paw naw. bayberrv or wax mvrtle, dog- 

 wood, plum, annle and pear trees. 



The new bulletin contains a cut of 

 the roso siug-c^ternillar which will in- 

 terest bnth rose erowers and nursery- 

 men. The otorpillar Is described as 

 attractively and strongly marked, and 

 about threp-fo"rths of an Inch In 

 length when full-grown. 



FIREBLIGHT. 



PirebHght is the most serious dis- 

 ease that attacks apple and pear trees, 

 and occurs In nearly every part of the 

 United States where these fruits are 

 grown. When Its cankers girdle the 

 branches they^ cause the leaves to turn 

 black, as though caused by a Are, and 

 often to remain on the tree throughout 

 the following winter. Flrebllght la 

 caused by bacteria, and myriads of 

 germs are present in all freshly blight- 

 ed parts of the tree and In the sticky 

 oozo from running cankers.

While cutting out ttie infected parts 

 and disinfecting tliem is the standard 

 treatment recommended, the details of 

 this work when done effectively are so 

 many and difficult that it takes many 

 pages of instruction and illustration 

 to make it plain to the fruit growers. 

 This detailed information is contained 

 in Circular Bulletin No. 7, Crop Post 

 Series No. 1, revised and brought to
