[Nhcoll-l] beetle colony invader

[Revelez, Marcia (CDC/OPHSS/CSELS/DLS)]

HI Aren,
I have had this experience personally.  Red-leggeds do kill/outcompete regular hide beetles.  If the invasion is early and if possible – monitor the colony closely and hand pick all individuals out – shouldn’t take long.  The worst thing is these guys getting into your collection area.  I am not sure how you treat your skeletons once coming out of the bugs – but if you do a classic water soak – these little guys seem to survive and hide well in any possible air pocket.  They love greasy specimens and can really be quite destructive to your specimens.

Do you know how they red-leggeds got into your colony?  Mine got in because someone brought in a specimen straight from the field – from that point I required carcasses to be frozen prior to entry.  If you aren’t familiar – you should explore https://urldefense.proofpoint.com/v2/url?u=http-3A__museumpests.net_&d=DwIGaQ&c=cjytLXgP8ixuoHflwc-poQ&r=LpYc_Z_iN1KRw0hheb3x6-8MJUMu482qfHowpGYJqwc&m=h7G7LzzFljP5scgksg72h074lIN19n-J044tGoaGNd8&s=wkK6Md8H0yLvbol5qFc-9nLH0BV3ooTP-Fv9_6O4JVg&e=.  It is a great resource and you can even join their listserv too (pestlist).  There is a fact sheet for many museum pests, including red-leggeds: https://urldefense.proofpoint.com/v2/url?u=http-3A__museumpests.net_wp-2Dcontent_uploads_2015_05_Fact-2DSheet-2DRedlegged-2DHam-2DBeetle.pdf&d=DwIGaQ&c=cjytLXgP8ixuoHflwc-poQ&r=LpYc_Z_iN1KRw0hheb3x6-8MJUMu482qfHowpGYJqwc&m=h7G7LzzFljP5scgksg72h074lIN19n-J044tGoaGNd8&s=qpJUhByQQ7_PZA9F-2VlCjOTxF1DoZjXi4slcP-W-wk&e=.

If it’s too late, hand pick as many hide beetles out as possible and start a new colony.  And yes, this is far easier than dealing with a mite problem…

Best of luck
Marcy

I can only speak from personal experience. It was easy enough to pick healthy larvae and adults from an infested colony for re-homing in a new aquariurm. Far easier than dealing with a (tiny) mite infestation.

Good luck!

Hi All,
Our dermestid beetle colony has been invaded by the red-legged ham beetle, https://urldefense.proofpoint.com/v2/url?u=https-3A__en.wikipedia.org_wiki_Necrobia-5Frufipes&d=DwIGaQ&c=cjytLXgP8ixuoHflwc-poQ&r=LpYc_Z_iN1KRw0hheb3x6-8MJUMu482qfHowpGYJqwc&m=h7G7LzzFljP5scgksg72h074lIN19n-J044tGoaGNd8&s=GrQQ_Ob6I7yA_pnux9qK5uI4L3rc_3BGrIMFCp0hiSw&e=<https://urldefense.proofpoint.com/v2/url?u=https-3A__en.wikipedia.org_wiki_Necrobia-5Frufipes&d=DwMFaQ&c=cjytLXgP8ixuoHflwc-poQ&r=LpYc_Z_iN1KRw0hheb3x6-8MJUMu482qfHowpGYJqwc&m=kBnbVAiIBvnm37vX57cDemsRZWRts-Qk4W2FalzXAWk&s=96xz_mW-gBvwLEmRKbKL2GUzT9qBmDqxnINLetD9Vmg&e=>. Does anyone have any experience with these guys commingling with their dermestids? Will they kill the dermestids or are they feeding on the skeletons?
Thanks,
Aren
