“and in the experimental orchard of the New York Experiment Station at Geneva, 
in connection with the PWA project of the Division of Fruit Insects. The project 
at the Geneva laboratory was concerned primarily with the use of light traps for 
controllin: the codling moth. Sinilar pollinating counts were made at an exper~ 
imental farm at Kearneysville, W. Va., where the codling-moth control measures 
_ involve the use of organic sprays. . 
PLANT DISEASE ERADICATION AND CONTROL 
Citrus Canker Eradication 
Two citrus canker infections have recently been reported from Texas. On 
May 11, 1934, during an inspection of an orchard east of League City, in Gal. 
veston County, our inspectors found citrus canker on two grapefruit trees. This 
orchard was badly frozen in February 1933 and since that tine the owner had re-~ 
fused to allow anyone in his orchard for inspection or otherwise, However, he 
recently sold the property and the new owner permitted entrance and inspection, 
_ Agents of the Sureau inspected this property on May 11 and found the two in- 
‘fected trees that had crown up from the stumps of this "freeze—back" of February 
1933, ‘The infected trees were immediately destroyed, and bichloride solution 
was used on the ground, and all nearby trees were thoroughly soaked with the 
solution. All other citrus trees in the orchard appeared to be in fine, healthy 
condition, setting a fairly good crop of fruit. This outbreak of citrus canker 
was recurrent from-an 014 outbreak that was showing up before the freeze, £ close 
watch, with spraying of this orchard, will be adhered to, The following trees 
remain on the premises: 211 satsumas, 2-year tops, 8-year root stocks Lz grape~ 
fruit, e-year tops, S~year root stock; 7 round orange, 2-year tops, 8-year root 
stock; and 43 satswnas, 2-year old nursery~stock row. 
On May 19, another infection was discovered near Algoa, Galveston County, 
Tex., where two Citrus trifoliata showed symptoms of the disease. The infected 
plants were growing near ke other C. trifoliata plants which were not infected. 
However, all of the C. trifoliata, numbering YY plants, were destroyed by the 
owner, 
Dutch Bln Disease Bradication 
In April and May the work: in er:Aication of Dutch elm disease changed fron. 
the winter program of searching for and eradicating Jiseased and beetle-infested 
elms to one of mapping the distribution of elms over the »alance of the area ine 
volved, preparatory to the beginning of the summer work. Despite the reduction 
in scouting, additional diseased trees have been found daily, bringing the total 
number of diseased trees on June 4, 1934, in New Jersey, New York, and Cennecticut 
to 1,532. Wilting of foliage from the disease wos first observed on May 19 in 
New Jersey. Considerable wilting was reported from Staten Island and some fron 
Westchester County, where extrerely severe defoliation by canker worms made such 
syuptoms rather difficult to observe, 
The first adults of Scolytus multistriatus Marsh observed this season in New 
York began to emerge on May 22, Adults of Hylurgopinus rufipes Eich,, the native 
@lm bark beetle, were first found in New York this season on May 10, before ener- 
gence from their brood tree, Pupae of Magialis sp. were observed on the same date.
