PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 1D 
In Burma Cerococcus hibisci is rather bad on cotton on the Experi- Mr. Shroff 
mental Farms. I have never seen a serious attack of this insect in a 
single cultivator’s field. I have used Crude Oil Emulsion with success 
as a spray against this pest. 
Saissetia (Lecanium) nigra [‘ South Indian Insects,” pp. 514-515, Mr. Fletcher. 
fig. 403] occurs fairly commonly on cotton, and ind-vidual plants or 
small patches of plants may be very badly attacked, the stems and 
branches of the plants being literally covered with the scales. The 
appearance of an attacked branch is shown in the figure in my book. 
The attack is usually very localized and can easily be checked by 
removal and destruction of the affected plants and any adjacent ones 
which are likely to be infected. 
In Mysore this Scale attacks the cotton plant and was very bad on mr, Kunhi Kan- 
one occasion. nan. 
The last Scale on our list is an unidentified species of Chionaspis Mr, Fletcher. 
which is occasionally bad on cotton at Pusa, but we have no record of 
its occurrence elsewhere. 
We now come to the insects found boring in the stem of cotton-plants :— 
Sphenoptera gossypi. : 
Pempheres affinis. 
Alcides affaber. 
,,  leopardus.

Zeuzera coffee. ; 
Sphenoptera gossypii [South Indian Insects,” p. 298, tab. 8] is 
widely distributed in India but seems rather localized as a pest. In 
Madras it is only known in the Bellary District, in the Central Provinces 
it seems to be worst in Berar, and in Bombay it is a serious pest in the 
Surat district, but in the other parts of India, although it may occur, 
it does not seem to be much of a pest. The life-history has been described 
in “ Indian Insect Pests,’ pp. 100-103, and there is not much to add. 
Control is best attamed by prompt destruction of all attacked plants, 
which wither and are quite noticeable. 
Iv Berar Sphenoptera gossypii was very serious about seven years ago, Mr, Ratiram, 
but the demonstration of uprooting and burning the affected plants 
has been very successful. The damage has now been reduced to a very 
great extent so that nowadays we find only about one plant attacked in 
a thousand. 
In Surat this pest is very serious, but the removal of the affected Mr. Jhaveri. 
plants has been found to be very successful. The pest is chiefly noticed 
in the young crop.
