NOTES OF THE YEAK IN NEW JERSEY. 



By John B. .Smith. 



During- the spring of 1890 the larva; of the Clover-leaf Beetle, Phyto- 

 nomus 2)unctati(s, appeared in great numbers and threatened to become 

 seriously destructive. A fungoid disease opportunely attacking them, 

 the vast majority were killed off before they were more than half grown. 

 Some few escaped, however, and the threat of injury was repeated dur- 

 ing the spring of 1891. The numbers were not so great, however, and 

 the fungus disease stepped in as before, destroying the larvae before 

 they had done serious injury. 



Complaints of twig blight in apple were made early in the season, 

 and on investigation two coleopterous insects were found to be con- 

 cerned in it. One of these, the larva of Eapogonlus tomentosus, bored 

 through the center of the new wood, or rather that made during the 

 previous year, and killed the twig. The beetles appeared in June. 

 The other was a small Scolytid,probablyi?^/)of/<ene»iws, which made short 

 galleries in the extreme tip of the twigs infested by the Lougicorn larva. 

 It is probable that this attack is secondary, and not made wiiile the wood 

 was sound. 



Some discussion was had at our last meeting concerning the points 

 of the tree attacked by the larva of Saperda Candida. This led me to 

 observe carefully during the present season, and I find that while in 

 quince the attack is almost exclusively at the base of the tree, in apple 

 and pear, any part of the trunk and even the larger branches may be 

 attacked. The larvai are more numerous at the base, as a rule, but the 

 other localities are not by any means exceptional. I know that no other 

 larvffi were concerned, because I cut out pup;e and imagines as well, 

 and am certain of my facts. 



Peach borers, the larvjie of Sannina exitiosa^ are now largely treated 

 by mechanical coatings to the trunk. The favorite means is the one 

 recommended by me in the bulletins of the station and at farmers' meet- 

 irigs. It is simply a thick whitewash with Paris green and glue added. 

 I have never discouraged the use of other mechanical coatings, but hav^e 

 taken great pains to explain that no remedial results must be expected; 

 that the measure was protective merely. Tlie use of paint, as sug- 

 gested by Mr. Alwood, does not find favor, owing to a fear that injury 

 may result to the tree. 



Blackberry insects have been particularly observed ; but as I have 

 already described these, a mere mention here is all that Is needed.
