Tra (Camellia theifera). 
We will start with the insects attacking the leaves of the tea-bush. 
Our list of tea-pests is very incomplete because we at Pusa have little 
opportunity of seeing them, but the following are known as more or less 
serious pests of tea :— 
Stauropus alternus. 
Biston suppressaria. 
Parasa lepida. 
Clania of various species. 
Heterusia of various species. 
Homona coffearia. 
Laspeyresia leucostoma. 
Contheyla rotunda. 
Olene mendosa. 
Andraca bipunctata. 
Phytoscaphus dissimilis. 
Coriyetus bidentulus. 
Taking these in detail :-— 
Stauropus alternus is occasionally found on tea and some years ago 
occurred as a sporadic serious pest of tea in the Kalutara District im 
Ceylon. It must therefore be regarded as a potential pest of tea in India 
It is by no means confined to tea, the larva feeding on Cajanus indicus, 
rose, tamarind and various other plants. 
It is found all over North-East India but no general outbreak has 
occurred so far. 
Mr. Andrews, will you tell us something about Biston suppressaria 
in North-East India ? 
This pest is worst all along the North bank of the Brahmaputra. 
It turns up every year but is sporadically serious in Sibsagar and Jorhat. 
There are three broods in a year, the second being the worst. As regards 
remedial measures, the pupe are found underground around the bushes 
and these are dug out by coolies when the soil is opened up around the 
bushes, as is now done on most gardens in North-East India every 
cold weather. Wherever this is done, the pest is reduced in numbers 
and the damage is gradually lessened. In one place the pest was bad 
in the first brood, and it was suggested to hoe around the bushes and 
collect all the pupz as soon as the caterpillars of the first brood had 
left the bushes; this was done and, as a result of this measure, the 
second brood was not so serious. This method has the advantage of 
being a cultural practice and can be practised annually. 
That seems a satisfactory means of control as it can be combined 
with ordinary methods of cultivation. Regarding the occurrence of
