MEXICAN FRUIT FLY ( Anastrcpha ludens Loew) 
The operation of some 5,600 flytraps resulted in the talcing of 5 adult 
Mexican fruit flics on the American side of the Rio Grande during May. These 
flics were taken in four groves, three of which'ha'C previously been reported 
as infested. No infestation had been previously reported from the other 
grove, which is located about 6jr miles from the nearest previously reported 
infestation. Fermenting malt was used principally as tho bait in the traps. 
In addition to the A. ludens taken in the traps, 181 adult A. -pal lens 
Cog. were also taken. The population of pal lens seems to have decreased con- 
siderably since, with a considerably larger number of traps in operation, 
the take of pall ens showed a decrease of 536 adults from the number taken in 
April. This fly seems to occur wherever the "La Coma" plant grows. Larvae 
were taken during the month as far west as Zapata and as far north as Raymonds- 
ville, Texas. 
GIPSY MOTH ( Porthctria di spar L. ) 
The first gipsy moth egg clusters were observed hatching this year on 
May 2. Hatching became general about May 9 and the maximum hatch occurred 
about May 13. These observations were made in several places east of the 
barrier zone. 
Up to and including May 28, there has been found by the Federal force in 
the barrier-zone area of southwestern Massachusetts and northwestern Connec- 
ticut a total of 67 infested sites aggregating 885 new gipsy moth egg clusters. 
The towns infested in this portion of Massachusetts arc New Marlboro, Otis, 
Sandisfield, Sheffield, and Tyringham. In Connecticut, the barrier-zone 
towns infested arc Canaan, Norfolk, North Canaan, Salisbury, and Warren. The 
farthest infested point in the barrii r-zonc area this year, in relation to the 
New York State line, is apnroxi-natcly 15 miles east of it. Salisbury, Conn., 
borders on the New York State line. 
GLADIOLUS THRIPS ( Tacniothrips gladioli M. & S. ) 
The gladiolus thrins, T. gladioli , has recently been found infesting 
gladiolus corns in Washington, D. C. , and vicinity, according to a memorandum 
received from the Bureau of Entomology. A brief survey by Bureau entomolo- 
gists among local growers and dealers resulted in finding infested corrns at 
two Washington stores from which many lots had been purchased, *nd an infested 
shipment had just been received by a local grower.
