SUG^MlCiilOl BOEER ( Piatraea sac char alls E. ) 
Louisiana. W, A, Douglas (March 25) s Results of exaraimations of rice stubs in 
10 representative fields in southern Louisiana showed mortality of 6 S per- 
cent, res-ulting from the unusually cold weather in January, The surviving 
population in rice stubs is estimated to be less than one-ha,lf of that 
surviving a normal winter in this section, 
E, K, Bynum, et al, (April lO): A total of 1,557 10-foot samples of 
burned cane tra.sh were exaxiinod in a number of fields on light and on heavy 
soil during the last of Eebruary and in March, In these examinations a 
total of 22,97^ sugarcp.no tops and pieces of sugarcane stalks were examined. 
Based on data obtained, the number of live stages surviving the winter, as 
compared with survivpl in 1939* ^as as follows: In light soil, S per acre 
in 19'+0 and 93 P^r acre in 1939; hca\"y soil, 6,5 in 19^0 and I3.2 in 
1939» Based on the examination of '3 r7lO stubs, the number of borers sur- 
viving the winter in stubs was 6,4 per acre, as cor.iparcd v/ith l7 per o,cre 
in 1939i nnd an average of 28,6 per acre for the period 1935“39* It is 
readily apparent that this last winter, the coldest in the sugarcane section 
since 1899* greatly reduced normal borer survival, 
A. L, Dugas (April '25)-: Very slow in making its appearance. The adverse 
weather conditions during the hibernation period reduced the number of over- 
wintered borers very materially, and, as a result j the damage by first-gen- 
eration borers is exceptionally light, ’

SUGARCjiUB BEETLE ( Euetheola rugiceps Lee,) 
Louisiana, J, W, Ingram and 1". E. Haley (April lO): Practically no beetle 
injury occurred in March, and injury on April 9 was less than 1 percent. 
Activity at loa.st 2 v;oeks lator than normal, owing to the unusuo,lly cool 
v/oathcr during March, Trapping of large nur-ibors of beetles at lights early 
in April indicates that most of them ha.ve emerged, 
A. L, Dugas (April 25): Observed on a plant action near Era:iklin on about 
April l6. Considerable damage done in nearly I50 acres of sugarcane on 
this plantation.
