That completes the insect pests of cotton, I think. Has anyone 
anything more to say about cotton-pests before we go on to bhindi ? 
In the Central Provinces, some experiments were tried at Telinkhedi 
Farm regarding the control of Earias on cotton by the use of bhindi as 
a trap-crop. Three plots were sown, one with cotton and bhindi, the 
second with cotton alone, the third with cotton and bhindi, each at a 
distance of one to two miles from the others. In the first plot the affected 
pods were destroyed and in the third plot this was not done. The loss 
percentage in plot No. 1 was about 5, whilst in Nos. 2 and 3 it was about 
25. 
There is no doubt that bhindi is useful as a trap-crop for Harias, 
provided that the affected pods and the trap-crop are properly destroyed 
at the right time. The difficulty in practice is to get this done. What 
happens is that the cultivator finds that he is getting an eatable or sale- 
able vegetable from the bhind: plants and he will not destroy 
these plants. A control method of this sort may be all right on Govern- 
ment Farms or on limited areas under proper supervision, but I think 
we should be very chary of recommending trap-crops of this sort on a 
large scale without a great deal more investigation on the subject. 
Buinpi (Hibiscus esculentus). 
The insect pests of bhindi and of other species of Hibiscus are, gene- 
rally speaking, very similar to those on cotton and in most cases they are 
identical, and it is as alternative food-plants for cotton-pests that these 
plants are chiefly of importance. So, as we have already discussed 
these insects under cotton, we need only run over them again very 
briefly. 
Bhindi seedlings are attacked by— 
Pachnephorus impressus. 
Agrotis flammatra. . 
Pachnephorus impressus has been noted at Pusa and Agrotis flammatra 
is chiefly of importance in the Punjab. 
Bhindi leaves are attacked by :-— 
Sylepta derogata. 
Acontia intersepta. 
> malve. 
>  transversa. 
Cosmophila erosa. 
Helcystogramma hibiset. 
Atmetonychus peregrinus.
