Corrected mortality (%) of eggs and third instar larvae of A. ludens and A. oblique at different atmospheres (kPa O2–kPa CO2), temperatures (°C) and exposure. Behavior and interactions between Anastrepha ludens (Loew) and A. oblique (Macquart) on field cage mango tree I. Lekking behavior and male territoriality. During sexual signaling, males of Anastrepha obliqua (Macquart) form leks and attract females by producing sounds and releasing volatile.

In order to characterize the reproductive behavior of A. The courtship and copulation occurred anastrepha oblique leks and the episodes varied with the time of day, courtship being most frequent between zeitgeber time ZT 3 and ZT 7, peaking at ZT Mean duration was 0.

The different timing of sexual behaviors among related sympatric species, including A. Introduction Northeastern Brazil has recently joined world market as a major exporter of tropical fruits, and Rio Grande do Norte has anastrepha oblique prominent position in this arena due anastrepha oblique increased irrigation of semi—arid areas.

Therefore, the need for pest control methods have also increased and the knowledge of reproductive behavior of tephritid fruit flies is relevant to improve monitoring, control, and eradication techniques.

One of the economically important species present is the fruit fly, Anastrepha zenildae Zucchi Diptera: Tephritidaea widely distributed generalist commonly attacking guava, Psidium guajava. The anastrepha oblique numbers of A. Among Anastrepha species it is common to find sympatric species that use the same hosts Zucchi In these instances, species isolation is presumably maintained by poorly understood isolating mechanisms, one of which might be differences in the diel patterning of sexual behaviors.

Anastrepha species exhibit species—specific temporal patterns of courtship and mating, possibly because of allochronic speciation or through divergence of a pre—copulatory isolating mechanism Henning and Matioli ; Aluja et anastrepha oblique. In Bactrocera, another species of economic interest, it has been suggested that circadian mating activity rhythms may cause allochronic species isolation An et al.

West Indian fruit fly - Anastrepha obliqua (Macquart)

Knowledge of the temporal aspects of reproduction is a tool to help develop monitoring programs of sympatric and morphologically similar species, and to optimally apply control techniques such as the release of sterile males. This study describes the courtship and mating behaviors of A. The wing is anastrepha oblique.

Drawing by Division of Plant Industry. Ovipositor sheath of female 1. Anastrepha obliqua bears a close resemblance to Anastrepha fraterculus Wiedemannbut it may be distinguished by the differences in the ovipositor of the female and a combination of several characters.

The pile of the mososcutum is sublaterally dark brownish black, of the median stripe yellowish white, the contrast very pronounced in Anastrepha obliqua, whereas in Anastrepha fraterculus the mesoscutellar pile is rather uniformly yellow-brown, that of the sublateral stripes scarcely darker than the ground color.

The black area on the side of the metanotum of Anastrepha obliqua usually reduced and the inner margin of the black area are not sharply defined, the postscutellum not darkened laterally, the wing bands usually all connected, whereas in Anastrepha fraterculus the black on metanotum usually extensive, and the inner margin sharply defined, the postscutellum anastrepha oblique laterally, and the wing bands often disconnected.

Anastrepha suspensa Loew also resembles Anastrepha obliqua, but differs from it in the same way as does Anastrepha fraterculus. Furthermore, Anastrepha obliqua lacks the pronounced median scutoscutellar black spot typically found in Anastrepha suspensa.

Larva white; typical fruit fly shape cylindrical-maggot shape, elongate, anterior end narrowed and somewhat curved ventrally, with anterior mouth hooks, ventral fusiform areas, and flattened caudal end ; last instar larvae range in length from 8—10 mm; venter with fusiform areas on segments 2 through 10; anterior buccal carinae usually 9 to 10 in number; anterior spiracles asymmetrical in lateral view with center depressed, and anastrepha oblique tubules averaging 12 to 14 in number.
