MEANS OF COMBATING THE GRASSHOPPER OT 
MEANS OF COMBATING THE JOLA GRASS HOPPER. 
Indirect combative measures.—The fact that, up to 
the present, the Jola Grasshopper has not attacked cer- 
tain crops, such as cotton, chillies and oingelly, to any 
appreciable extent, would suggest the possibility of com- 
bating the pest indirectly by growing these crops for a 
number of years in the infested tracts to the exclusion of 
the crops that are attacked and in this way starving out 
the grasshopper. As a matter of fact, a number of the 
raiyats cultivating lands in_ the infested area have ex- 
pressed their intention of going in largely for the culti- 
vation of cotton and chillies this year. 
That this method could not be applied thoroughly 
enough to get rid of the pest, is fairly certain, while it 
would tend to increase rather than to decrease the danger of 
spread. While cotton is at present a very profitable 
crop and an increase in its acreage would be bene- 
ficial, it must not be forgotten that jola forms the 
staple article of food for both man and beast in this 
region, and anything which would seriously and perma- 
nently decrease its acreage might lead to disastrous 
results during years of scarcity. On the other hand, 
there is always the decided danger that, as soon as 
the more favoured articles of diet are removed, this grass- 
hopper will cultivate a liking for those crops which it now 
leaves untouched. The fact that it has appeared as a pest 
only within the last seven or eight years, indicates that it 
isat present in a decidedly adaptable stage in its evolution 
and the alternative between feeding on plants at first 
somewhat distasteful, or starving, might lead to the neces- 
sary change in feeding habits, in which case, instead of 
bringing about the control of the pest, we should simply 
have increased its destructiveness. 
Direct combative measures.—These may be directed 
against this grasshopper either in the egg or in the 
nymphal stage. Any measure directed against the adult 
stage would be comparatively useless, even if possible to 
apply, for by that time the insect has practically completed 
its destructive work. Practical measures that could be 
applied towards the destruction of the eggs would be most 
suitable, as we should thus be able to destroy the insect
