Effects of IGR's on moth developement

Hello all,


I am new to the boards and had a few questions I was hoping someone may be able to answser.  I am wondering if the juvenile hormone mimics like pyriproxifen and hydroprene lengthen the larval stage of the moths?  If so, by how much?  I was under the impression these products do not effect the insect until the pupal stage when exposed as a larva.  While hydroprene does not have a registration for clothing moths, a product containing pyriproxifen does.  It was recently told to me that exposure to these products would be counter productive as it extends the larva stage of the insect which is of course the stage that does the damage.  It is my feeling the effects on reproduction outweigh the extension of the juvenile stage if this does in fact occur.  All comments would be appreciated.


Thank you,
