PLANT INSECTS 
BOXtOOD 
BOXWOOD LEAF-MINER ( Mo narthro palpus buxi Labou.) 
New York E. P. Felt (June 23). "The box leaf -miner is well established 
on Long Island and in southern Westchester County, occurring 
ia enormous numbers on groups of box and causing serious 
injury. The flies began to emerge about the middle of May, 
most of them coming out in immense swarrrs within a few days, 
though a few remained in the larval stage until June 16. 
The best control at Port Chester was secured by using 6 
pounds of molasses to 50 gallons of water and making applications 
every other day." 
New Jersey Richard Kfeizing (June l) . "This pest is proving quite serious 
to boxwood at Eatontown and Elberon." 
Pennsylvania J. K. Primm (May ll) . "This is the worst pest of box where 
it occurs and is now invading nurseries and private estates 
in Montgomery County which were free from it two years ago. 
Adults began to emerge May 1 in 1921 and on May 8 this year. 
The dwarf box, Buxus s uf f ructicosa. is nearly immune from 
attack, but other varieties may be heavily infested. It is 
now quite generally distributed throughout Philadelphia, 
Bucks, Montgomery, Chester, and Delaware Counties of this 
State." 
AZALEA 
AZALEA LACEBUG ( Stephanitis pvrioides Scott) 
.Pennsylvania J. K. Primm (May 27). "Marked browning of leaves is notice- 
able at this early date on hardy azaleas. In 1921 many 
azaleas were defoliated in southeastern Pennsylvania due 
to this insect. Specimens of the evergreen varieties 
succumb to this attack when not sprayed in time. Nicotine 
sulphate, 1 part, to 500 parts water is an effective control." 
LILAC 
LILAC BORER ( Podosesia s vringae Harris) 
New York E. P. Felt. "Mr. R. E. Horsey reports that the lilac borer 
( Trochilium denudatum ) is so serious in the lilac collection 
in Rochester Parks that it is necessary to go over the bushes 
carefully to remove breakage."
