sweets poisoned with arsenious acid and corrosive sublimate, 

 and placed on paper in shallow pans in the. trees, failed to attract 

 them. 



3. Sticky fly papers seem to be useless. We exposed several 

 sheets in the branches of a tree where the flies were thick, for 

 three days, and only took a single Trypeta fly. 



PREVENTIVE MEASURES. 



1. Keep the orchards in grass and in the fall or spring burn 

 under the trees to destroy the pupae that are about the grass roots. 



2. If the orchard is in cultivation the conditions are favorable 

 for the maggots to go into the ground, but they never go deeper 

 than an inch and deep spading or plowing in the spring would 

 destroy them. 



3. Orchards ou sandy soil and in sheltered places with a 

 southern exposure are worse affected. In planting orchards such 

 conditions might be avoided. 



4. Prevent by legal enactment the importation of foreign fruit 

 from localities known to be infested. The pest was undoubtedly 

 introduced into the State by importation of foreign apples. And 

 each year there is a new invoice from Mass. in imported early 

 fruit. We taw in the Orono market to-day a barrel of early 

 sweet apples from Mass. literally alive with nearly full grown 

 Trypeta maggots. No matter what methods are adopted to check 

 this pest they will prove futile if each year in all the towns of the 

 State maggots by the hundreds are thrown upon the ground in 

 worthless infested foreign fruit. 



DIRECT METHODS. 



1. The flies are very stupid although the} 7 appear otherwise. 

 When resting on the leaves or apples they can readily be taken 

 with a small insect tube or bottle. By placing the mouth cau- 

 tiously over them, they are not disturbed, and soon crawl inside. 

 We took thirty this way from a single tree in an hour and a half. 

 Making no allowance for mishaps and supposing a fly lays three 

 hundred eggs and one-half of the flies are females, the progeny of 

 a single fly the third season would be capable of laying nearly 

 seven million eggs. The killing of even a few flies would 

 materially lessen the number and hold the pest in cheek. 



2. The fact that the larva? do not leave the fruit before it is 

 ripe and are still found in abundance in the windfalls, would 

 indicate the most vulnerable points in the life history of the insect 

 and suggest two methods of checking the pest, viz. : Taking
