Scotinopkara coarctata, Fb. 
This Pentatomid, called “ Kutu Bruang ” in Malaya, 
is black in colour, and about Va inch in length. The 
nymphs and adults suck the .sap from any part, but. 
especially from the lower portions t of the plant. 
Attention should be paid to. the seedlings when 
transplanted from the nurseries, to see that all 
plants are free from eggs, nymphs and adults. 
When the irrigation water can be controlled, the 
padi should be flooded. Nymphs and adults rising 
to the surface of the water can then be collected. 
All stages of this insect can exist on stubble and 
volunteer padi growing between padi crops, so that 
consideration should be given to the disposal of the 
stubble and to the prevention of the growth of ■ 
volunteer padi. 
Leptocorisa spp., (“Padi Fly,” “ Pianggang ”) . 
This Coreid bug, which is probably the most serious 
pest of padi, sucks the sap from the developing padi 
grains. 
The adult is recognised by its greenish brown 
colour and elongate body. The eggs, which are laid 
on the upper surface of the leaves, are brownish in 
colour and very conspicuous, being laid in chain 
formation parallel to the mid-rib of the leaf. They 
hatch in about 7 days and the nymph’s, in common 
with the adults, suck the sap. The adult condition 
is attained after a period of about 18 days from the 
hatching of the egg. 
This insect lives on the inflorescences of several 
grasses until the padi begins to ripen and after the 
crop has been harvested, so that grasses should be
