REPORT OF THE ENTOMOLOGIST.

tared specimens. The egg state, therefore, lasts but a short time — six 

 to eight days — and the young larva on hatching spins a few threads as 

 supports, eats for a day or two from the outside skin until it becomes 

 H to 2 mm in length) and then burrows into the berry and enters upon the 

 life-history recorded in my previous report. There is in consequence 

 great difficulty in reaching either egg or young larvae, 



One feature observed is that the insect was found only on high, warm 

 boys, and that in some localities where last season the insect was very 

 common there was no trace of it; all these bogs, however, had either held 

 the water very late or had reflowed. In localities where the bog is low 

 and wet there always is less attack of worm than in high, dry situations. 

 Since leaving the ('ape I have received specimens from one spot where 

 no trace of worm was visible when I left; but they are nowhere common. 



It is difficult to judge exactly how much shall be attributed to the 

 effects of reflowage, and how much to the cold, wet spring, which de- 

 stroyed so much vegetation as well as insect life. Certain it is that on 

 about all high, warm bogs which either could not be flowed or where 

 the water was taken off early, the berry -moth was found in some num- 

 bers, while on none of the low, wet bogs which had been reflowed was 

 there any trace up to the 17th day of July. Later, I understand, a few 

 appeared; but very few, compared with previous years. I would, there- 

 fore, recommend also that the bog be kept as wet as possible during 

 July, and the ditches nearly full of water. In some places this would 

 be injurious to the fruit after it had well set, but while the plants are 

 in blossom the wet is rather favorable than otherwise. The effect of 

 this would be to destroy most of the pupae, or at any rate to so retard 

 their development that the larva would not destroy more than one berry 

 during its life-time. 



THE FIRE-WORM. 

 (Anchylopera vacciniana Pack.) 



This insect, the Fire- Worm, which had in previous seasons done so 

 much damage, has this year been kept pretty well under control. 

 Growers had generally adopted the suggestions of my report and per- 

 sonal advice given to such as I met, and had used the water where pos- 

 sible, and always with great benefit if not absolute success. Some have 

 gone to large expense to procure sufficient water, and others have made 

 great preparations in that line, so that this insect once so destructive 

 will itself in the course of a few years be so reduced in numbers as to 

 be comparatively harmless. In Cape Cod, tobacco steeped or boiled is 

 still the favorite remedy, and is undoubtedly effective if applied 

 thoroughly and seasonably; two applications at brief intervals are 

 necessary, and from 1 to 1J pounds to a gallon of water should be 

 used. The tobacco is said to have fertilizing properties. It is, how- 

 ever, very expensive. The kerosene emulsion has been used to some 

 extent, and where judiciously used has proved successful; where there 

 was no success the fault was with the emulsion, which was not perfect 

 Churning with a barrel-stave was tried by some, and of course the re- 

 sult was not as complete as desired, for the emulsion obtained was 

 neither complete nor stable. 



CRANBERRY LEAF-FOLDER. 



(Teras oxycoccana, Pack.) 



In my previous report I stated that this insect was not found in Mas- 

 sachusetts, and at that time I had neither succeeded in finding it my- 

 self, nor had any growers to whom I described it noticed it. This season
