Coconut rhinoceros beetle

Checked again this morning.  Zero count.  But I can see ALL OVER THE PLACE where the feral chicken is digging through the leaf litter that covers about 3/4 of the 2 acres.

As of today this is a list of my palms or those I've heard of that have been attacked by the CRB.  I'm sure there are many others around the islands that I don't know about.

I believe all but my Pritchardia beccariana have recovered due to  injections and spraying with imidacloprid

AdonidiaMerrillii

Arenga macrocarpa

Cocos nucifera

Coccothrinax

Copernicia berteroana

Hyphaene coriacea

JubaeopsisCaffra

Licuala grandis

Pritchardias (All)

Roystonea

Syagrus sancona

Veitchia arecina

Veitchia joannis

Cindy, I just chose a spot that was in a clearing and about 6’ off the ground for access. The lure packets that are available for the trap come in an aluminum sleeve that you peel off exposing the clear plastic pouch. You can smell the chemical attractant immediately.  The chemical is contained on a felt like disc within the sealed plastic pouch, so no liquid. Yours is a different design and must disperse the smell through the plastic.

Have you caught any ?  Know of any on your island?

I have not caught anything yet, BUT Alphascents wants me to wait a few more days before puncturing the plastic bulb that contains the lure specific for the ox rhino beetle. Soon it will be time to puncture it and then maybe capture some!

No coconut beetles in PR I am told but I would need the ox beetle and the coconut beetle side by side to begin to tell the difference! 

As to palms attacked by ox beetles on my farm, it is interesting that not much overlap. See below.

AdonidiaMerrillii- have but no attacks

Arenga macrocarpa-don’t have but so far no Arengas attacked

Cocos nucifera-have LOTS but no attacks

Coccothrinax-Maybe one attack not killed 

Copernicia berteroana-have and no Copernicia species attacks

Hyphaene coriacea-don’t have

JubaeopsisCaffra-don’t have

Licuala grandis-have lots and most are attacked 

Pritchardias (All)-have and most attacked

Roystoneas-have LOTS and no attacks

Syagrus sancona-don’t have

Veitchia arecina - have other Veitchias not attacked

Veitchia joannis-see above

Lots of other genera attacked when young by ox rhino like Chambeyronia, Kerriodoxa, Pelagodoxa, Rhopaloblaste, Archontophoenix, Ravenea, Calyptronoma, Calyptocalyx, Chrysalidocarpus, Geonoma,Asterogyne, Loxococcus, Mauritius, etc.

Some killed, some saved. So far,  once trunking, no more holes in or near stem and healthy palms. 
 

As a zoology major, all of this is of interest despite the losses, especially the different species attack preferences and adult palms versus juvenile Palm targets. 
 

Please keep posting your results.

How goes the CRB on the Big Island?  Spreading?
