Trapping for Pheletes canus Lec.--R. S. Lehman, Walla Walla, re- 
ports that "An interesting experiment was tried this year in which fe— 
male wireworm beetles were placed in the trap to attract males. One 
trap containing females captured 719 males in one day. An observation 
meade in the field showed that the males were attracted for at least 
50 feet by the females. It is also interesting to note that female 
Pheletes californicus Mann. are just as attractive to male Pheletes 
ee ee res 
canus Lec. as are females of their own species." 
Relative abundance of wireworm species.~-E, W. Jones, Walla Walla, 
reports: "Effort has been made to find the relative abundance of Phele— 
tes canus Lec. and P. californicus Mann. in the cultivated land of 
Walla Walla Valley. Population statistics based on some 2,500 samples 
and collected during 1931 have been summarized for this report." A 
table (submitted) shows that "The average population in the Walla Wal- 
la Valley for P. canus Lec. fields is 9.5 per sq. ft. and for P. cali-= 
fornicus Mann. fields, 8.6 per sq. ft. A study of the table indicates 
that there are evidently specific limitations in the local distribu- 
tion of the forms. P. canus, for example, is least abundant in fields 
that are not in truck crops. On the other hand, P. californicus shows 
a preference for field crops and is least abundant in truck crop gar-— 
dens." 
Tobacco stalk borers long lived.—-Longevity records made by K. B. 
McKinney, Tempe, Ariz., "from a general assortment of 232 bred and col- 
lected adult stalk borers (Trichobaris mucorea Lec.)" show that 90.5 
per cent lived longer than 10 days; 56.5 per cent longer than 20 days; 
6 per cent longer than 101 days; 3.9 per cent longer than 150 days; 
and 1.7 per cent longer than 201 days. "One individual that emerged on 
Aes tele 951, (livediciledays."' 

Lesser bulb fly.-—-F. J. Spruijt;, Babylon, N. Y.5voreportenewee 
bulb insect investigations, says that the totals of this year's (1932) 
Eumerus samples taken are: In greenhouses, 123 males, 106 females; in 
dump heap, 58 males, 7 females; or a grand total of 181 males and 1135 
females. "Thus far only one species of Eumerus has been taken, namely, 
E. tuberculatus Rond." 
Vapor heat treatments not injurious.—-Reporting on vapor heat treat— 
ments of narcissus bulbs, Mr. Spruijt says: "No injury (to foliaggues 
flowers) due to treatment could be detected. Flower records were begun 
in the second half of the month; the flowering was at its prime during 
the last week of the month." 
Effects of vipor treatment on the flowering of out-door narcissus.—— 
Continuing studies on the effect of vapor heat treatments of narcis— 
sus bulbs, Randall Latta, Sumner, Wash., reports that in the continu— 
ous treatment series King Alfred bulbs "treated for the second consecu— 
tive year showed no detrimental effects in the flowering * * * Treat— 
ments from September 8 on showed an increasing amount of blinds." Glo-
