Although it is not known how widely Lygidea mendax, Reut. (false 

 .apple red bug) is distributed in New Jersey, it is a very serious 

 menace to apple production there. A brief statement as to life- 

 history and control taken from C. R. Crosby [Cornell Univ. Agric. 

 Expt. Sta., Bull. 291 (1911)] is given, and it is noted that Heterocory- 

 ■ dalis malinus, Reut., which usually accompanies L. mendax, has not 

 yet been taken in New Jersey. 



Leptobyrsa explanata, Heid. (the rhododendron lace-bug) gave 

 some trouble. According to E. L. Dickerson, this species is found 

 on the under side of the leaves of both rhododendron and mountain 

 laurel, where it lays its eggs in the leaf tissue along the mid-rib ; 

 it is in this stage that the winter is passed. Hatching begins in New 

 Jersey in early May, sometimes a little earlier, the insects becoming 

 fully developed in about a month, and it is believed that later in the 

 season there is another brood. Infested plants should be sprayed 

 in May, the younger the insects the more effective will be the spraying ; 

 1 lb. whale-oil soap to 4 lb. U.S. (3| Impl.) gallons of water is satis- 

 factory, but the under sides of the leaves must be reached. 



Extensive damage was done to cranberries, and this was found to be 

 due to the cranberry katydid and not to the grasshoppers and crickets 

 found on the bogs. Few complaints of injury from white-grubs were 

 received, and damage by Galerucella luteola, Mull, (elm-leaf beetle) was 

 comparatively slight. Epitrix cucumeris, Harr. (potato flea-beetle) was 

 the worst insect enemy of the potato, and besides consuming the leaf, 

 this species transfers blight ; plants well covered with Bordeaux mixture 

 are not seriously injured and this will, besides controlling the adult 

 above ground, indirectly prevent injury to the tubers by the grubs. Two 

 reports of threatened destruction of potato plots by the blister beetle, 

 Epicauta vittata, ¥., were received, but in both cases arsenical poisons 

 prevented destruction. Macrodactylus subspinosus, F. (rose beetle) 

 appeared in considerable numbers on grape foliage, but was promptly 

 checked with arsenate of lead and glucose spray (5 lb. lead and 12 lb. 

 glucose to 50 U.S. (41| Impl.) gallons of water). Conotrachelus 

 nenuphar, Hbst. (plum curcuho) seems to be holding its own, but a fairly 

 satisfactory control can be obtained by the use of arsenicals. Scolytus 

 rugulosus, Ratz. (fruit-tree bark-beetle), attracted much attention by 

 its work on peach, but the attacked trees, under proper cultivation, 

 pruning and spraying, may recover and bear much fruit. In certain 

 parts of New Jersey, S. quadrispmosus, Say (hickory bark-beetle) 

 is almost as serious a pest of hickory as the chestnut-bark disease is 

 of chestnut, and as yet no really satisfactory control measures have 

 been found. Chloridea (Heliothis) obsoleta, F. (corn-ear worm) was 

 very abundant, infesting nearly 100 per cent, of all sweet maize ears 

 in late summer and early autumn ; a full account of this insect forms 

 a special part of this report. Cutworms were frequently reported, 

 but poisoned bran mash proved a specific against them. Tkyridop- 

 teryx ephemeraefortnis, Steph., again attracted attention, but this 

 bag-worm is so well understood that it should not be allowed to do 

 serious harm. Zeuzera pyrina, L., (leopard moth) seems to have 

 remained stationary, nor has the position in respect of Cydia pom- 

 onella, L. (codling moth) undergone any important change. Melittia 

 satyriniformis, Hb. (squash-vine borer) attracted much attention, 

 but cutting out the borers has been practised with satisfactory results.
