SUGARCAHE 
SUGARCANE BORER ( Liatraea saccharalis Fat.) 
Louisiana 17. E. Kinds (September 26); The sugarcane "borer is now 
increasing in abundance noticeably as' the third generation 
matures and the fourth generation, is starting. Infestation is 
most apparent in P.O.J. 213 cane. Egg collections made in many 
fields during September 1 to 15 showed no trace of Trichogramma 
in a number of localities.;. The o„verage percentage of natural 
parasitism by Trichogramma in uncolonized check areas during 
the period from July 11 to September 1 has ranged from 6.6 to 
22.6 per cent. In the average of all colonized areae during 
this period parasitism has ranged from 57.9 to 71.6. While in 
the average of fields adjacent to colonized areas the percentage 
has ranged from 35,6 to 68.9. It is expected that the peak of 
parasitism- 'will be reached in cone fields before the middle of 
October on 4th generation borer eggs.
