The damage in Meneria was 10-6 per cent. 



The damage in all the other 25 varieties, mostly thin, 

 taken together was 9 per cent. 



It would appear that the damage in these plots was 

 about the same as in the Purple Mauritius plots from which 

 all affected plants had been cut out and destroyed with the 

 insects in April. 



Throughout May Chilo simplex and Sesamia infer ens 

 were feeding in Rabi maize and to a very small extent in 

 Rabi juar. 



In the latter part of June the damage in the Purple 

 Mauritius plot was about 25 per cent., the following being 

 responsible for it : — 



Red Rot about 15-4 per cent. 

 Papua depressella about 6 per cent. 

 Diatroea suppressalis about 2-2 per cent. 

 Scirpophaga xanthogastrella about 1-1 per cent. 

 Termites about 0-2 per cent. 

 Sesamia infer ens about 0-06 per cent. 

 A few Diatrcea venosata were found at this time. 

 All affected plants were cut out and destroyed with the 

 insects. 



About this time the damage in Sathi No. 131 was about 

 10 per cent. As far as could be judged by external examin- 

 ation, about 3-5 per cent, was due to Red Rot and about 

 6-5 per cent, to insects. 



Sathi No. 15 suffered to the extent of about 8 per cent., 

 damage due to Red Rot being about 2-5 per cent., and that 

 due to insects being about 5-5 per cent. 



Damage in Meneria was about 14-3 per cent., Red Rot 

 being responsible for about 11 per cent, and the insects for 

 about 3-3 per cent. 



The damage in the other (mostly thin) varieties taken 

 together was about 7 per cent., Red Rot being responsible 

 for about 3 per cent, and the insects for about 4 per cent. 



About this time Chilo simplex was practically absent 

 from maize and juar.
