ANASTREPHA SERPENTINA PDF

Biology and ecology[ edit ] Natural history and life cycle[ edit ] Females lay their eggs in either developing and healthy fruits or in mature and rotten fruit like the A. The vast majority of species use their ovipositor to deposit the eggs in the edible part of the fruit either the epicarp or mesocarp , and some species such as A. Once larvae is fully mature make a hole to come out of the fruit, and it most happen when the fruit is on the ground. Then, the larva makes a hole on the ground to become a pupa. The life cycle begin again when the female emerge and become mature to produce eggs by feeding on sources of carbohydrate and protein. Infested fruit with larvae of Anastrepha suspensa.

This species was first described as Dacus serpentinus by Wiedemann It has been classified in several different genera. The current combination was proposed by Schiner in Description For a general description of the genus, see the datasheet on Anastrepha. Adult As in most other Anastrepha spp. The following description is taken from Norrbom : The body is largely dark-orange to dark-brown with yellow markings and the setae are dark-brown. Head: mostly yellow.

Ocellar tubercle brown. Orbital plate often with paired triangular brown area; frons rarely red or red-brown between these areas forming a single large mark. Frons occasionally orange to pale red-brown anteromedially. Occiput usually with paired, triangular or comma-shaped, brown mark near or covering suture of median occipital sclerite.

Facial carina, in profile, concave. Ocellar seta weak, small to minute. Antenna extended 0. Thorax: mostly orange-brown to brown with the following areas yellow and distinctly contrasting: postpronotal lobe; single medial and paired sublateral vittae on scutum, the slender medial vitta extended nearly the full length of the scutum, broadened posteriorly, but extended laterally only slightly beyond the level of the acrostichal seta at most half distance to level of dorsocentral seta ; sublateral vitta extended from transverse suture almost to posterior margin, including intra-alar seta; scutellum except extreme base brown area usually well-separated from basal seta, but sometimes narrowly separated ; dorsal margin and anteroventral corner of anepisternum; dorsal halt to all of greater ampulla; dorsal margin of katepisternum; katepimeron; and most of anatergite and katatergite.

Mesonotal darker areas mostly red-brown to dark-brown, often with narrow orange area bordering medial vitta, and less commonly with small sublateral presutural orange area; without orange vitta on dorsocentral line. Most of darker areas of anepisternum, anepimeron, meron, and katatergite dark brown. Katepisternum usually orange anteriorly and ventrally, brown posteriorly. Subscutellum and mediotergite red-brown to dark-brown, sometimes narrowly orange medially.

Mesonotum 2. Katepisternal seta weak, at most as long as postocellar seta, yellowish. Wing: length 6. Vein M strongly curved apically; section between bm-cu and r-m 1. Crossvein dm-cu distinctly oblique, with anterior end more distal than posterior end. Pattern mostly dark-brown. Abdomen: predominantly brown with yellow and orange areas forming T-shaped pattern. Male terminalia: dorsal posterior margin of epandrium evenly convex. Lateral surstylus moderately long; in lateral view slightly curved; in posterior view usually with small basolateral lobe, main part triangular, acute apically.

Proctiger with lateral fold separating sclerotized areas. Phallus 3. Glans 0. Female terminalia: oviscape 2. Eversible membrane with large, hook-like dorsobasal scales in triangular pattern.

Aculeus 2. Immature Stages The key by Steck et al. White and Elson-Harris described the third-instar larvae as follows: Larvae: medium-sized, 7. Oral ridges of rows of small ridges with irregular serrations along posterior margins; accessory plates large, anterior ones with small serrations along margins; mouthhooks moderately sclerotised, each with a large curved apical tooth.

Dorsal spinules absent from A1-A8. A8 with area around spiracles protuberant, with obvious intermediate areas. Dorsal and intermediate tubercles and sensilla very obvious, ventral sensilla smaller. Anterior spiracles: with tubules. Posterior spiracles: spiracular slits approximately 2. Distribution Top of page A. It occurs at low to middle elevations throughout mainland tropical America, from Mexico to northern Argentina. Lucia, unpublished data. The status of A.
