NEWS ITEMS FROM THE TEMPE, ARIZ, LABORATORY. 
Tempe, Arizona, August 18,1917. 
During the past month V.1,Wildermutn has been making an extended 
insect survey through the northern part of Arizona. He has been accompanied, 
for a portion of the time, by Dr. 0,C.Bartlett, Assistant State Entomolo- 
gist. 
Third-instar larvae of Lanhygma fruziperda have been observed 
feeding on the tassels of field corn. The species is makkng its ap- 
pearance about two weeks later than in 1916, 
Heliothis obsoleta larvae are much more numerous in alfalfa than 
in previous years. Their presence in alfalfa is probably largely due to 
the fact that the species is predaceous on the larvae and pupae of Eurymus. 
Larvae of Prodenia ornithogalli have been very numerous in alfalfa 
and corn, but no serious demage has been reported owing to the fact that the 
wilt disease has made its appearance and greatly reduced the numbers of the 
larvae. 
The threatened outbreak of Eurymus in the Salt River Valley of 
Arizona and in the Imperial Valley of California has been checked by the 
wilt disease. Unusually moist conditions in these lécalities, supplemented 
by the use of recommended cultural methods, have contributed to the check 
of the species, 
Stictocephaia festina is doing its usual amount of damage and is 
particularly numerous in alfalfa. 
Dr. W.M.,Wheeler of Bussey Institution; Prof. J.C.Bradley of 
Cornell and Prof. C.L. Bequoret of the American Museum of Natural History 
spent about a week in this vicinity, collecting material, and were fre- 
quent visitors at the labvoratory.
