the winter in Louisiana was about normal, being several times greater than in 
19 U 0 , but somewhat less than in 1939 ; however, the number of first-generation 
borers found in fields was about equal to that in 1939 * The percentage of 
joints of sugarcane found bored in Louisiana at harvesttime in 194l was esti- 
mated at 20»l6, This estimate is based on a systematic survey conducted jointly 
with A* L. Dugas, of the Louisiana Agricultural Experiment Station,, Estimated 
percentages of joints bored in the 6 previous years, based on similar surveys, 
were: 1940, 5 . 3 ; 1939, I9e7; 1938 ; 15*9; 1937. i' 6 # i; 1936 , 8*7; «id 1935, 8 . 1 . 
In limited examinations made in southern Florida in September, in cooperation 
with J, W. Wilson, of the Florida Agricultural Experiment Station, the infesta- 
tion in the vicinity of Clewiston was found to be somewhat lighter than in previ 
ous years, .and in the Canal Point area the infestation was somewhat heavier. 
The infestation in the Fellsmero area was lower than average and it was apparent 
that the 68 percent larval parasiti zation by lixo phag a dia traeae Towns 0 and 
Bassu s sti gma, t orus Cress* had been a factor in reducing the infestation. W, A, 
Douglas, in. surveys to determine the borer infestation in rice, found the in- 
festation 'in Texas to be the lowest on record, and the Louisiana infestation to 
be lighter than normal'. (J. W. Ingram, Bureau of Entomology and Plant Quaran- 
tine, U. S. D, A.) 
BLACK GRAIN STEM SAWFLY, — During the summer of 194l Trachelus . tabidus F. 
was found in greater abundance in southern Virginia than at any previous time 
and reached within about 10 miles of the North Carolina border c However , sur- 
veys of wheatfields in North Carolina showed no signs of it having reached this 
State, The following* tabulation summarizes the results of the survey by coun- 
ties and shows the average percentage of culms infested in samples taken from 
several fields in each of the following counties;
