Description of Caenorhabditis angaria n. sp. (Nematoda: Rhabditidae), an associate of sugarcane and palm weevils (Coleoptera: Curculionidae)

Description of Caenorhabditis angaria n. sp. (Nematoda: Rhabditidae), an associate of sugarcane... AbstractCaenorhabditis angaria n. sp., an ectophoretic associate of the West Indiansugarcane weevil, Metamasius hemipterus (Coleoptera: Curculionidae) isdescribed and illustrated. Data on biology (longevity, fecundity) andecology are presented. Caenorhabditis angaria n. sp. is gonochoristic andcan be differentiated from other species of Caenorhabditis by itscomparatively short stoma in combination with six semicircular overlappingflaps on the lips, lack of a pharyngeal sleeve, one pair of teeth on eachsector of the metastegostom, and a proximally open bursa with nine pairs ofgenital papillae (GP) and papilliform phasmids (ph) in a 2/2 + 2 + 3 + pharrangement with GP4 and 7 opening dorsally. Caenorhabditis angaria n. sp.was isolated and cultured from M. hemipterus from Dade, Broward and PalmBeach Counties, FL, USA, and from Port-of-Spain, Trinidad, and from theAmerican palm weevil, Rhynchophorus palmarum, from Trinidad. The nematode isphoretically associated with weevils as dauer juveniles without causingobvious deleterious effects. Caenorhabditis angaria n. sp. does not requirethe association with a weevil and can be cultured continuously onbacteria. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nematology Brill
