PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 5d 
In the beginning of the experiments, in 1911, a large number of 
moths was trapped, but in spite of such a large catch, the caterpillars 
did attack the Farm crops. This shows that light attracts the moths 
from distant places also. When the traps were continued, the attack 
decreased in severity from year to year. 
Bagging was also tried on Cotton and Sann-hemp grown for green- 
manuring and was found very effective in the latter case. 
Handpicking of moths was also tried in the mornings and evenings 
but it was not very successtul. 
At what time of year do you get damage done to crops 2 Mr. Fletcher. 
The worst outbreak occurs in June and July. It is the first brood Mr. Jhaveri. 
which is always bad. 
That is not in agreement with our experience in Madras. There Mr. Fletcher. 
the moths emerge in a similar way after the first showers of the monsoon 
but there are relatively few caterpillars from this lot ; it is the second 
and often more especially the third brood of caterpillars which occur 
in such large numbers and do damage. If the first brood is checked 
by hand-picking, little damage follows later on as a rule. Of course, 
the broods run into one another, but roughly that is what happens. 
In Mysore, in the case of Amsacta albistriga, tt has been noticed that Mr. Kunhi 
hardly any females were attracted to light-traps. There hand-collecting Kannan. 
of the moths is successful and it has been suggested that local legislation 
should be introduced whereby a cess would be levied on the cultivated 
areas where this insect does damage and the money paid back to the 
villages for collection of the moths by children, at the rate of 1 anna 
for each dozen moths collected. 
In Bellary, Amsacta albistriga occurs in larger numbers than A. Mr. Ramachandra 
mooret, but in South Arcot both species occur in about equal numbers. Rao. 
Amsacta albistriga and A. mooret are often found coupled. Have mr, Fletcher. 
you reared any hybrids ? 
No ; none have been reared as yet. Mr. Ramakrishna 
Mr. Madan Lal, you told us just now that you had used light-traps eee 
successfully in the Punjab to control Amsacta moorei on moth. Can 
you tell us the proportions of the two sexes in the moths attracted to 
your traps ? 
Roughly half were males and half females. Mr. M. M. Lal. 
The great differences in the effect of light-traps as control measures, Mr. Fletcher. 
both as regards the total number of moths attracted and the propor- 
tion of the sexes in various localities, is very noteworthy. 
Acherontia styx [“ South Indian Insects,” p. 402, tab. 24] oceurs 
in most localities as a minor pest of lablab. The larve may be hand- 
picked, but are not always easy to see.
