Storage pests (Sitophilus oryzae, Rhyzopertha dominica)
Larva of storage moths (Ephestia cautella, Corcyra cephalonica) and bruchid beetles (Callosobruchus spp.) cause extensive damage to soybean grains.
The forewings of the adult moth E. cautella are greyish-brown with an indistinct pattern. The wing span is 1-2 cm.
- Rice husk ash was found to be effective against bruchid beetles (Callosobruchus analis) in Indonesia. Fresh, dry ash should be used, at a rate of around 1% of the seed weight. The rice husk ash should be spread by hand over well-dried soybean seeds stored in a can with a capacity of 6 - 18 litres. The ash should be gently mixed with the seed by hand, and the lid placed tightly on the can. The can should be kept in a cool, dark place (Naito, 1981).
