PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING Ql 
D. citri has proved a very serious pest, so much so that Mr. Woglum, 
an Expert of the United States Entomological Service, visited the Far 
East, including India, about six years ago especially to endeavour to 
collect parasites and predators of this Aleyrodid. You will find an 
account of this in one of the publications of the Bureau of Entomology 
and that contains all the information we have about the occurrence of 
Dialeurodes citri in India. 
Toxoptera aurantiu is apparently the common Citrus Aphid in India. 
It is often abundant and destructive on the young shoots, and is best 
controlled by a fish oil soap spray. 
Euphalerus citri is a Psyllid found commonly on orange plants in 
India. It is usually a minor pest, occasionally occurring in large num- 
bers. A contact spray, such as fish oil soap, is usually effective. 
There is one other sucking insect which is not on my list but about 
which I want to say a few words, and that is Icerya purchasi.. It is 
not on my list, because we have not yet found it in India ; but it is a 
thing to look out for because we have just received a warning from the 
Ceylon Government that it has been found in Ceylon and it is therefore 
possible that it may invade India also. This Scale-insect is a well- 
known pest of orange and lemon trees in Australia and New Zealand 
and has also spread to South Africa, Fiji, Hawaii, Portugal, Trinidad, 
Mexico, and the United States of America. Besides Citrus, it may 
attack a long list of other plants amongst which I may name rose, Acacia, 
grass, Casuarina, pomegranate, apple, peach, apricot, fig, pepper, grape, 
castor, Polygonum, potato and Amaranthus. I have here some figures 
[exhibited] of this Scale-insect, and I will have copies of these made and 
circulated, so that you will be in a position to recognize this insect and 
report its occurrence immediately to Pusa, should you come across it. 
Bae (dgle marmelos). 
The pests of bael are very similar to those of Citrus and hence are 
rather important because bael may provide an alternative food-plant 
for Citrus pests. 
On bael leaves we get :— 
Clitea picta. 
Phyllocnistis citrella. 
Papilio demoleus. 
Myllocerus discolor. 
Clitea picta (Chrysomelide) is a specific pest of bael, attacking the 
leaves and shoots and often doing a good deal of damage. At Pusa 
about June the leaves are riddled with patches eaten out by the beetles,
