Unfortunately T. nigrescens has no or only a very low impact on other storage pests e.g. Sitophilus spp. or Tribolium spp.

10. Integrated pest management 1996

It is effective against most storage pests (exception: Sitophilus spp.), in particular against all species of the family of Bostrichidae such as Rhyzopertha dominica and

Sitophilus spp. develop inside the grains and are thus not noticeable in controls of this kind.

5. Central storage 1996

They are sufficiently persistent in stored grain, but have a rather poor effect on Sitophilus species.

(Sitophilus zeamais), causing almost 100 percent mortality after 15 days of exposure.
