Aphis gossypii [“ South Indian Insects,” p. 499, fig. 388] is common 
on cotton in most districts but is rarely a serious pest, being kept in 
check by predaceous insects. It is fully described in “ Indian Insect 
Pests ” (pp. 110-111) and in Bulletin No. 10 (pp. 1-2), and I do not think 
there is much more to say about it. In the case of small experimental 
plots it can be checked by spraying if it appears in any numbers but 
this is hardly practicable on a field scale, when we must leave the natural 
enemies of this Aphid to keep it in check. 
A species of Empoasca is common on cotton and seems to be especially 
prevalent and destructive in the Punjab. This species also is described 
in “ Indian Insect Pests” (pp. 108-110) but we have not yet been able 
to get it named up definitely. 
Will you tell us about it in the Punjab, Mr. Madan Mohan Lal ? 
At Lyallpur Empoasca was once serious on American cotton. The Mr. 
leaves of this variety of cotton are not hairy, consequently the attack 
is serious on this variety. One plot was sprayed with Fish-oil Soap and 
it decidedly improved after spraying. Another point observed was that 
the weaker plants suffered more than the healthy ones. The leaves 
curl up as the result of attack. 
In the case of the attack of Hmpoasca on tea microscopical exami- Mr. 
nation of the attacked leaves reveals that the leaf-cel!s are congested 
considerably as the result of the attack and this restricts the flow of the 
sap ; the leaves are consequently stunted. 
At Poona Empoasca has only been noticed on one occasion in any mr, 
numbers on exotic cotton. 
As regards the sporadic way in which Empoasca may occur I can Mr. 
tell you of a case which happened with the Hmpoasca found on tea. 
A plot of 32 acres, right in the middle of a block of 5,000 acres of tea- 
bushes was seriously attacked by Empoasca. No one could tell where the 
insects had come from. The attack came on at the end of July and 
cleared up in August. Since then it has never reappeared. 
Can you tell us anything about the life-history of this Hmpoasca on Mr 
tea ? 
The eggs are very small, oval, and are laid on the surface of the mr 
lea ves of tea.
