Subject: Mexican bean beetle control
> Have you tried the bean beetle parasite, Pediobious foveolatus? It is
> available from some suppliers and I could give you some sources if you
> wished. Some researchers have had success with annual releases of this
> species during early stages of a field infestation.
> I can't help with a trap crop and doubt that this would work since most
> beans are roughly equal in attractiveness. I presume that infestations
> are first concentrated along the field edge and if you could plant and
> flail or otherwise destroy this sacrificial patch it might help.
> (Unfortunately the Mexican bean beetle does not show the sharp preference
> for early plantings, as does the bean leaf beetle. With the latter
> species you could concentrate the great majority of the infestation on
> the earliest planted beans, making a very effective trap crop.)
> Neem and rotenone are two insecticides that are generally acceptable for
> bean beetle control in Certified Organic production. However until
> federal standards are in place determination of what is or is not
> acceptable is up to individual states. You would have to check with the
> New Mexico Department of Agriculture regarding what is acceptable for
> organic certification.
> I hope this is some help.
