Several years ago India Meal Moth began to infest our feed mill in Aurora, NE. We saw only marginal control with chemical use.

The webbing created by the moths grew to the point where we had to physically remove it from the top of the bins and machinery yearly.

In 2002 we began a control program using BRACON HEBETOR and TRICHOGRAMMA provided by BIOFAC CROP CARE.  Since then we have seen a large reduction in the moths.

In 2003 we did not have to clean webbing, so we saved on labor costs and kept our employees safer, because they did not have to go into the bins.

I have less concern now about moths and their eggs being transported with the feed to a customer’s facility.  BIOFAC BENEFICIAL INSECTS ARE WORKING FOR US WHEN CHEMICAL CONTROLS DID NOT.

Primary Pests in Stored Grain.  Learn how pests destroy your crops and what Biofac does to stop them.  Other insect species or groups of species described in this protection program can cause great damage to grain if storage conditions are unusually favorable for their increase.  Yet, if grain in the unbroken kernel remains unaffected by the five primary pests, it is not likely that any other insect will damage it appreciably in commercial storage or shipment, except possibly the khapra beetle, which does not occur at present in the United States. 

The secondary pests are mostly surface feeders in both the adult and larval stages.  Some of them, may eat into kernels of grain and lie hidden there, but most of them feed on grain dust or broken surfaces of kernels exposed by either mechanical injury to the grain in handling or by the feeding of the five primary grain pests with which they are usually associated.  Therefore, the secondary pests can largely be removed by grain-cleaning operations.

Except for the lesser grain borer, the larvae or grubs of the primary insect pests are not ordinarily capable of a free existence outside the kernel.  They live entirely within the kernel, where they feed unseen and usually unsuspected.  They can not be removed by ordinary cleaning machinery and must be controlled by other means.
