196 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
Epacromia tamulus and other grasshoppers occur, often in numbers, 
in wheat areas and must do some damage, but it is scarcely perceptible 
as a Tule. 
Boring in the stem of wheat plants we get Sesama inferens. Sesamra 
uniformis does not seem to have been bred from wheat so far. We have 
injerens recorded from wheat at Surat, Nagpur, Seoni and Pusa, and 
it probably occurs throughout the wheat-growing areas in India, but it is 
scarcely a pest and direct control seems rather out of the question, except 
in so far as the stubble question is concerned. 
Sesamia inferens is found in the Punjab but is not serious. 
At Pusa also it is not serious. 
Besides the usual micellaneous lot of cockchafer grubs and so om 
the roots of wheat plants are attacked by 
Microtermes obesi (anandt). 
Aphids. : 
Microtermes obesi (anandt) has just been considered under the heading 
of seedlings. In some districts, however, notably m the Central Pro- 
vinces, wheat plants are attacked just when they are coming into ear 
and the damage done may be serious, two to three annas in the Rupee: 
in normal years and four or five annas in bad years. Damage of this 
sort occurs at Hoshangabad and the subject was taken up for investiga- 
tion in 1910 by Mr. Lefroy. He visited the Farm and mapped out all. 
the visible termites’ mounds, which occur as a rule along the field embank-- 
ments, and started a series of experiments on the extermination of these 
nests by (1) digging them out, (2) oiling with low-grade kerosine oil. 
and digging them out, and (3) simply pouring a bottle of low-grade 
kerosine oil into one of the main galleries of the nest. In 1911, when 
Mr. Lefroy went on leave, I took over this work and visited the Hoshanga- 
bad Farm in September 1911 and noted results to date and continued 
the experiments with the new mounds which had showed up. The ex- 
periments carried out at that time appeared to have demonstrated 
that the simple oiling of nests is sufficiently effective to render this worth 
while. As careful estimation of that year’s wheat crop on the Hoshanga- 
bad Farm showed that one-third of the total crop had been destroyed 
by termites it was reasonably supposed that the cost of treatment 
(about one anna per mound treated) would be more than repaid by 
increased out-turn, and an experiment on these lines was arranged to be 
done by the Deputy Director of Agriculture, one block of wheat fields 
to be left untreated and in another similar block of fields all the mounds 
being destroyed. 
In February 1912 I visited Hoshangabad again to see the result of 
this experiment, but no apparent difference was perceptible. The
