REPORT 01? STATE ENTOMOLOGIST. 5 1 



only spray that can harm them is a contact spray, one that 

 reaches the body of the insect. 



The usual remedy is kerosene emulsion, whale oil soap or a 

 similar solution. 



If they are not discovered before the leaves protect them by 

 curling it is a very difficult matter to control them. The only 

 safe way is to keep a sharp watch and as soon as the first ones 

 appear they should be destroyed at once. It will be necessary 

 to keep a close watch and spray again, possibly a third time. 

 The eggs do not generally all hatch at the same time. If the 

 first brood can be destroyed the trees are generally secure from 

 attack for that season. Practically all of the Gregory orchards 

 were slightly infested with this pest. 



BROWN-TAIL MOTH WORK. 



In most sections this pest is being handled in a more satis- 

 factory manner by the town authorities. In its early history 

 there was so much prejudice to overcome that but little effective 

 work could be accomplished, but with the continued infesta- 

 tions the public in general has come to realize that the problem 

 must be met and the sooner this is done the better. We hardly 

 think there has been any further spread northward as no re- 

 ports have come to the office from new territory. No damage 

 of any extent has been reported outside of York and Cumber- 

 land counties. It is very gratifying indeed to note, as intimated 

 in the beginning of this report, that the fungous disease planted 

 out in 1907 again made its appearance during the favorable 

 weather in June, and destroyed millions of the feeding cater- 

 pillars. As a result of this much fewer moths were seen during 

 their annual flight, although many came across the border from 

 New Hampshire. It would seem to be a wise move on the 

 part of our neighboring State if she would plant out this disease 

 on her own territory, and thus rid her towns of a large number 

 of these pests. This insect can be controlled in our orchards 

 by one spraying in July, and the time is not far distant when 

 all owners of fruit trees will realize this fact and put it into 

 practice.
