Eighth Report of the State Entomologist. 21 9 



Both the bud-moth caterpillar aud the pupiie of the apple-leaf Buccu- 

 latrix could be destroj^ed by the arsenical spraying repeated as often as 

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

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

 ceptible swelling of the buds. Possibl}^ at this time (April 29th) 

 some of the Bucculatrix moths have emerged, and have commenced 

 depositing their eggs. 



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 bodj^, 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 noAV or wait until 

 after the blossoming. Please answer as soon as possible. 



Reply to the above Avas made, that although the little gra}^ moths 

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

 there Avas hardly a doubt that they Avere 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 noAv seen Avill make their appearance, Avill 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 Avith 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 pyricola Foerst. This insect was referred 

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

 April 16th, entitled, " Honey-DeAV on Pear TAvigs." A fcAv days since 

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

 George T. Powell, of Ghent, N. Y., which shoAved a formidable attack 

 by this pest. The living insects Avere seen Avhen the buds Avere picked, 

 but Avhen thev came to me onlv their dead and shriveled remains could
