Orthalicus as a pest
11-07-2008 12:02
Searching for literature about snails as pest
species, I came across a paper* describing Orthalicus
maracaibensis (Pfeiffer, 1856) attacking Citrus spp.
It was reported from Yumare in northern Venezuela.
The nice thing about the paper was the multitude of
pictures from live specimens :-)
Update: Carl Christensen sent me this paper of Deisler, who states that tree snails may be beneficial "because they feed on epiphytic growths." The only other record I have on Orthalicoidea as agricultural pests, is this paper by Stange. He cites that Amphibulima patula dominicanus Pilsbry, 1899 has been reported as feeding on citrus.
