244 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
Boring insects in peach trees include 
Arbela tetraonis 
which has been noticed boring peach-trees at Pusa, but it does not seem 
to be a regular pest of peach. 
The sucking insects found on peach include :— 
Monophlebus stebbingi octocaudata. 
Lachnus sp. 
Hyalopterus. sp. 
Monophlebus stebbingi octocaudatus occurs on peach as on so many 
other trees. We have already dealt with this under mango. At Pusa 
this scale sometimes occurs on the trees in regular masses. 
Lachnus sp. is a large brownish Aphid common on peach-trees at 
Peshawar. It occurs in masses usually on the underside of branches, 
not on the leaves. The colonies can be dealt with fairly easily. 
Hyalopterus sp. is the bright green Aphid occurring on peach leaves. 
It is common in Kumaon and at Peshawar and is controlled by spraying, 
as Mr. Robertson-Brown will tell us. 
Spraying on a large scale is done in the orchard on the Agricultural 
Station at Taru, near Peshawar. Peach is a very sensitive tree and is 
easily affected by even a weak solution of any oily spray. After com- 
parative trials, Katakilla has been found very useful against Green Aphis 
and is applied by means of Holder Sprayers. The total cost of appli- 
cation per acre comes to Rs. 12, the number of trees ranging from eighty 
to one hundred. The strength used is in accordance with the directions 
given on the packet. In my opinion it is always better to use proprietary 
insecticides ; it is no good making up a solution or emulsion on the spot. 
Katakilla has been found very efficacious in killing all the three species 
of Aphids which give us trouble and my opinion is that the Aphis problem 
can easily be solved by thorough spraying with Katakilla. 
Any more pests of peach ? 
In the Central Provinces, at Pachmarhi, there is a butterfly which 
pierces and sucks the sound fruits. 
Kallima inachus has been reported to do that at Pachmarhi but the 
record seemed so doubtful that I omitted it from our list. Possibly 
the fruits are first pierced by a Noctuid moth such as Ophideres. 
We should like a further definite observation of damage done by Kallima 
and, if you can substantiate that, you can send us a short note on it for 
publication in the next Bulletin of Entomological Notes. 
Pium (Prunus cerasifera). 
We have few pests recorded on plum, probably because it is little 
grown in the Plains.
