The Anterior Peristigmatic Glands in Trypetid Larvae

Tephritoid Flies (Diptera, Tephritoidea) and Their Plant Hosts from the State of Santa Catarina in Southern Brazil

“…Two spe-cies of the genus Parastenopa, P. guttata and P. montana, were reared. The only Parastenopa species previously known to attack this plant were reared from stems or from leaf galls of the Paraguay tea psyllid, Gyropsylla spegazziniana Lizer & Trelles (Hemiptera, Psyllidae) (Blanchard 1929; psyllid as Metaphalara spegazziniana), although the North American P. limata (Coquillett) breeds in the fruit of several Ilex species (Benjamin 1934;Phillips 1946). Araticum, Annona rugulosa (Schltdl.)…”

MORPHOLOGY OF THE IMMATURE STAGES OF DACUS TRYONI (FROGGATT) (DIPTERA: TEPHRITIDAE)

“…Maxillary palps reduced, bearing numerous sensilla on distal segment. Mouth opening ventral with projecting mouth hooks and stomal sense papillae (Snodgrass 1924;Phillips 1946) either side of each mouth hook; preoral teeth (Kandybina 1961) anterolateral to mouth opening with 6 pairs of large unserrated teeth surrounding stomal sense papillae. Either side of mouth opening a transverse series of radiating furrows (oral ridges) with 9-12 rows of deeply serrated blunt edged teeth.…”

A Review of the Leaf-Mining Fruit Flies (Diptera: Tephritidae) of Canada and the USA, with New Host Plant and Distribution Records

“…The latter fact is worth noting since if the plant Frost collected was in fact asteraceous, the expected tephritid leafminer in that region would be T. flaveola Coquillett, a species whose hosts and immature stages were unknown when Frost and Phillips did their work. Examination of larvae of E. fratria and T. flaveola (both collected by BDS and GJS at Great Smoky Mountains National Park) reveals that neither is consistent with Phillips' (1946) description and illustrations of Frost's larvae from Prenanthes . For instance, in both species the cephaloskeleton differs in shape from Phillips' drawing and the mouthhook has two teeth instead of just one (Fig.…”

“…being used by any leafminers other than agromyzid flies. Phillips (1946) described the larva of E. fratria based on “three specimens reared by S. W. Frost at Ithaca, N. Y. from Prenanthes canadense .” Although she used the word “reared,” we have found no evidence that there are adult specimens associated with this collection; there are no Frost specimens of Tephritidae at Cornell University (where he conducted his graduate work) or the USNM. At Penn State's Frost Entomological Museum, there are four specimens of E. fratria , which were collected in the Ithaca region although they do not list Frost as the collector.…”
