Abstract

Toumeyella parvicornis (Cockerell) (Hemiptera: Coccoidea: Coccidae): a new invasive pest of pine trees in Puerto Rico.

Abstract

T. parvicornis was detected on young Honduran pine (Pinus caribaea) at a private residence in Ponce, Bo. La Yuca, Puerto Rico, on 17 February 2009. Further inspection of the source nursery in the Guilarte State Forest on 28 February 2009 revealed almost complete infestation of the seedlings. Severe damage to twigs and foliage was observed, with extensive damage and death caused to shoot terminals. Infested twigs had a greyish black appearance caused by the build-up of sooty moulds. Both females and immature stages, including larvae, were observed. This is the first report of T. parvicornis, and of a member of the genus Toumeyella, from Puerto Rico. The morphology of T. parvicornis is briefly described.
