W, A, Stevenson (October 1'): L, L, Stitt, of the Tempo station, reports 
that in the Ynma and Moha’^vk Valleys, Yuma County, considerable damage has 
been inflicted to seeding alfalfa in' some fields. Moths reared from larvae 
collected in the- alfalfa fields confirmed the identity of the species. So 
' far as me are aware, this is the first authentic record of damage to alfalfa 
in Arizona by this common cotton insect, ■

a large number of, apples at the Experiment S tot ion orchard. Some varieties 
were on the ground for about 2 weeks and during that period about 5 percent

orchard, 
Virginia, C, M, Paclcard (October 24): On October l4 a single larva ’ivas found by 
E, E, Dicko in the corn experimental plot -at Arlington Earn, ’As the airline 
distance to the nearest previously knovm infestation, Delav;are and the Eastern 
Shore, is about SO miles, there seer.s reason to suspect that additional near- 
by areas of infestation' may ■ exist in Virginia and Maryland, (Bet, -by C, 
Heinrich.) 
Guam. R, G, Oakley (August 31 )j Average infestation of corn during the periods of 
hoav;.’’ corn planting, maturing normally in June an.d July and in December and 
January, a:- found in 5I fields scattered about the island for throe crop 
seasons, the third ending in July 1938, WcHs estimated at 4 percent. 'The 
heaviest infestations found in those three periods amounted to only 7 percent, 
whereas some fields scouted gave negative findings. The average paras it iza- 
tion.by Lydella s tabul-iuis Meig, yox, amounted to SO percent. The average 
infestations in scattering fields maturing several weeks later than the normal 
crop were fo’und to increase, Tw^i^ such fields in S-eptember 1937 bore 20u and 
26-ptrcent infestations, respectively, but with 93 percent paras it izat ion. 
In A\v^;st 1938 t’'.'^o fields boi’e 5O- and 70-percent infestations, respectively, 
of the borer, Pnrasitization by L, stabulans in these cases s-nmeunted to about 
98 percent, D^nge by the borer in all but the t’wo last-mentioned fields 
appeared to be of little impertnnee. Three borers per stalk were rarely found 
in an infested stalk, two borers per infested stalk were not common, except 
in the heavier infestations, aiid one borer; per stalk did not appear to’ materi- 
ally affect the size of the ear,
