Agric. Punjab, 1907). We may draw attention to the International 
importance of Bollworm; India might produce very large quantities 
of cotton, especially the long-stapled cottons now required. India 
does not, very largely because Bollworm in India is a serious bar 
to the growth of any but the existing short stapled cottons which 
mature rapidly and offer little scope for Bollworm attack. 
MANGO MEALYBUG. — In India, two very important trees 
flower and fruit between March and July. These are the mango 
and the jackfruit. Both are attacked by a Giant Mealybug (Mono- 
phebus octocaudata), which has a very peculiar life-history; it is 
one-brooded; the eggs, laid in April, do not hatch till November 
and the Bugs take till April to become mature. They require very 
large quantities of food at a time when the mango and the jack- 
fruit trees are putting out new shoots and flowering; settling on the 
shoots they suck out the sap rising to the fruits and the fruits drop 
off while quite small, the crop of mangoes and jackfruit being then 
very smali. Till now the matter has been looked on as hopeless, 
and even an entomologist would express doubts over a Mealy- 
bug in the warm climate of India having only one brood a year; 
but now we have worked it out and there are two simple remedies; 
the first is to band the trees and prevent the Bug getting up to 
develop or down to lay eggs; the second is to destroy the eggs laid 
in the debris at the foot of the trees, these eggs lying there from 
April to November (see « Mem. Agric. Dept. », vol. II, n° 6). These 
methods are now in use in North India where this pest occurs. 
These are instances of the work that has to be done and which 
is being done in India now. We are not doing this violently all 
over India, but where we can; where a pest turns up and really 
does harm enough to make the people want to do something, we 
try to organise a campaign. The work is at its very beginning, and 
against many pests we cannot even suggest the lines of work, as 
the preliminary study has never been done, but this is being done 
and as the class of work is being better understood, we are 
getting nearer to being able to tackle our pests by direct active 
work of this kind. 
It must be remembered that in India only a very little can be 
done by publications of any kind, by the ordinary methods useful 
elsewhere. We must go to the cultivator, show him, put pressure to 
bear on him and, as a rule, actually do the work for him at the
