oa Journal of the Entomological Society of Southern Africa - A contribution to the morphology of Apion soleatum Wagner (Coleoptera: Apionidae). A pest of cotton. The larva and pupa, including a discussion of spiracular form

 

Abstract

The external structure of the larva and pupa of A. soleatum was investigated. The larva conforms well with the general curculionoid form, but it possesses some unusual features, not commonly found amongst curculionoids. The maxillae bear flattened, paddle-shaped dorsal malar setae, while the epipharyngeal setae are of a thickened, club-shaped form. A new system for spiracular terminology is presented since current terminology remains confusing. Two spiracular forms are present: annular bicameral on the thorax, and annular unicameral spiracles on the abdomen.
