The adult open wingspan is 10mm-23mm. Adult moths have pale yellow
forewings and grey pointed hindwings. The wings are narrow with
wide fringes. Identification is unreliable – seek expert
help.
Significance
It requires whole grain or caked material to develop. By preference
the female lays her eggs in barley, rye, corn, oats, rice and various
seeds. Development of an infestation causes considerable heating
and increase in moisture of grain.
Control
Infested commodities should be destroyed or failing this fumigated.
Following this the application of a residual insecticide to cracks
and crevices, wall floor angles should be carried out. ULV space
spray treatments would also be useful in controlling an infestation.
