Hypomeces squamosus, Fb. (Curculionidae) . 
This weevil is very common in Malaya and, when 
present in large numbers, does considerable damage 
by eating the leaves of various plants. It is parti- 
cularly bad on kapok, which is only in leaf for 
a short time. Breeding takes place in the soil on 
the roots of various grasses and cover-crops. 
Spraying with lead arsenate causes some reduction 
but, should the insect be present in large numbers, 
the ploughing up of grass and cover-crops all round 
the area attacked will have to be considered. 
Anoviola cupripes, Hope, and Adoretus compressus , 
Weber. ( Rutelinae ). 
These insects are night-feeding, leaf -eating beetles. 
As in the case of Hypomeces squamosus , breeding 
takes place in the roots of various cover-crops and 
grasses, and control measures are similar to those 
given above. 
Valanga nigricomis, Burm., and Cyrtacanthacris 
luteicomis, Serv. 
Numerous grasshoppers, (Acridiidae) , are always 
present ; the two mentioned above are typical. With 
this class of insect it should be remembered that the 
young form is like the adult, only without wings, 
and that the young nymphs begin feeding almost 
as soon as they hatch out from the eggs. Control 
measures vary with conditions, but the use of 
poison sprays and baits, the spraying of grass or 
cover-crops where the insects congregate and the 
destruction of egg-masses by cultivation, where 
possible, are methods usually adopted. 
It has been observed that cover-crops harbour 
grasshoppers in large numbers, and instances have 
occurred where young coconut palms were only
