Eighth Report of the state Entomologis -j|<> 



Both the bud-moth caterpillar and the pupae of the apple-leaf Bu< 

 lntrix could be destroyed by the arsenical spraying repeated as often as 

 found necessary. It would have been more efficient could the spraying 

 have been done two week- earlier, or at about the time of the first per- 

 ceptible swelling of the buds. Possibly at this time (April 29th) 

 some of the Bucculatris moths have emerged, and have commenced 

 depositing their eg 



A third note of inquiry,from Mr. Frank Mothrop of Lincoln, Wayne 

 county, dated April 26th, is as follows: 



Since receiving your reply to my letter concerning spraying our 



orchard. I have found three different insects that I would like much 

 to know about, and I accordingly send them to you in this mail. The 

 first is a small gray miller, which appears in numbers about my apple 

 trees, especially in warm, sunshiny days. The second is a small green 

 louse, of which there seem to be from one to four on every bud. Are 

 they hurtful to the fruit, and what will have to be done to kill them? 

 The third is a worm of about one-eighth of an inch in length, with a 

 black head and brownish body, which seems to be eating into the bud. 

 I do not find many of this kind, but I fear that more will hatch out. 



These insects are giving us a good deal of anxiety, and we would 

 like to know if it would be better to spray for them now or wait until 

 after the blossoming. Please answer as soon as possible. 



Reply to the above was made, that although the little gray moths 

 sent had lost nearly all of their scales in catching and handling them 

 there was hardly a doubt that they were the eye-spotted bud-moth 

 (named in the preceding notices), particularly as some of its larvae, 

 but recently hatched, were found feeding in the buds. This is the 

 third insect mentioned in the above note. The oviposition of the bud- 

 moth extends over quite a period of time, so that the conjecture that 

 others than those now seen will make their appearance, will probably 

 be confirmed. The observed flight of the moth in the daytime is of 

 interest, as it has not been recorded. No time should be lost before 

 spraying with Paris green for the caterpillar. [See Note A, 

 appended.] 



The second insect, mentioned as "a small green louse," indicates a 

 new and dangerous attack in the orchards of our State, viz., that of 

 the pear-tree Psylla, Psylla pyrieola Foerst. This insect was referred 

 to in a communication made by me to the Country Gentleman for 

 April 16th, entitled, " Honey-Dew on Pear Twigs." A few days since 

 some blossom buds were brought to me from an apple orchard of Mr. 

 George T. Powell, of Ghent, X. Y., which showed a formidable attack 

 by this pest. The living insects were seen when the buds were picked, 

 but when they came to me only their dead and shriveled remains could
