NOTES FROM THE MARTINEZ (CAL) FIELD STATION. 
: March 1, 1917. 
: The winter, so far, has been one of unusually low temperature compared with 
the normal for the Bay region of California, and the rainfall has been considerably 
_ below the normal. 
/ The heavy frosts have undoubtedly greatly retarded the normal insect 
7 developement in this section of the country. The grains have been sprouting in 
the first fields since the middle of January and early in February the adults of 
the Hessian fly for the season began to emerge from the old wheat stubble and to 
| deposit their eggs on the young wheat plants. This is the first emergence of the 
adults of Hessian fly since early in the spring of 1916, 
| ‘Adults of Isosoma grande, form minutum, were also first observed in 
. earing in the fields. 
a ert. f pipbrotion soror have been observed on warm days since the 
middle of January and a few have probably been present throughout the entire 
winter in the adult stage.
