TRUCK CROP AND GARDEN INSECTS 
Fertilizers have no effect on wireworm injury.—-F. H. Shirck and 
assistants coiducted "An experiment (at Parma, Idaho) to study any pos- 
Sible effects that commercial fertilizers or barnyard manure may exert on 
wireworms. The following fertilizers were used: Ammoniun sulphate, 
muriate of potash, treble phosphate, complete fertilizer, formula 5-19-10, 
Stable manure, fish meal, and bone meal. The commercial fertilizers were 
applied at acre rates of 250 pourds, 500 pourds, and 750 pounds, each 
fertilizer being used three times at each rate. Corn was the crop used. 
About 90 per cent of the corn was killed by wireworms, either before 
germination or soon after. Our population counts had indicated popula— 
tions of 2 wireworms per square foot: There seemed to be no evidence 
that any of the fertilizers used affected the wireworms or reduced the 
damage done by them." 
M. W. Stone, of the soil insects laboratory at Alhambra, Calif., re— 
ports that 77 females of P. californicus taken at random from adults 
collected in the field and placed in salve cans "deposited 8,778 eggs, 
or an average of ll4 eggs per female; 535 eggs were recovered by dis-— 
section; females averaged 24.4 days alive, beginning with their confire- 
ment in salve cans; th2 average number of days from capture to pbegin-— 
hing of egg deposition was 3.6 days." 2
