GENERAL CONCLUSIONS 39 
4. This pest feeds on the leaves and grains of practi- 
cally all dry land cereals grown in the State. It also feeds 
upon the leaves and flowers of leguminous crops and to a 
very shght extent on chillies and cotton. Up to the pres- 
ent, the damage to these latter crops has been negligible, 
but it is quite possible that, should it be deprived of other 
food, it might do great damage to these crops also. 
.5. HEges are laid in the soil of the fields as well as in 
land bordering them, in November and December. The 
egos hatch during the following July and August. The 
insects require from two and a-half to three and a-half 
months for development. 
6. While there are a few natural enemies which 
feed upon the eggs and the grasshoppers, these cannot be 
relied upon to keep the pest in check. 
7. It is possible that careful ploughing early in the 
season to a depth of four inches, together with thorough 
cultivation afterwards, may lead to a large destruction of 
the eges, but this has not, as yet, been proved. 
8. Deep ploughing with an improved plough to a 
depth of eight or nine inches buries numbers of the egg- 
masses so deep that the young hoppers are not able to 
emerge. A thorough test of this method must be made on 
a fairly large scale before definite conclusions can be 
reached as to its efficacy. 
9. The catching of the young hoppers by means of 
bags swept over the crop has proved a very efficient 
means of keeping the pest in check. It should be begun 
not later than the beginning of August, and should be 
repeated three or four times or even more. For the best 
results, all the raiyats and land-owners in the infested 
tracts must co-operate. The work should be considered a 
part of the cultural operations more important even than 
weeding and should be done with the same care and _ re- 
peated with the same regularity. The appearance of 
grasshoppers in the fields after the first bagging is to be 
expected just as much as the appearance of weeds after 
the first weeding. Here, asin other agricultural opera- 
tions, only persistent and repeated labour is likely to 
yield good results. The expenses of bagging should not 
exceed Re. 1 per acre, provided the necessary co-operative 
effort is made. 
In conclusion, it must be emphasized that the recom-
