“…Após a separação, a fêmea iniciava a limpeza do ovipositor com suas pernas posteriores, e o macho iniciava a limpeza do edeago (Fig.2g). De Lima & Howse (1997) observaram comportamento pós-copulatório semelhante para A. fraterculus (Wiedemann, 1830).…”

“…O comportamento pré-copulatório observado para A. sororcula apresentou muitas semelhanças com aqueles já descritos para outras espécies deste gênero, como: A. bistrigata Bezzi, 1919, A. fraterculus, A. ludens, A. obliqua, A. serpentina (Wiedemann, 1830 e A. suspensa. Os machos dessas espécies também apresentaram comportamento caracterizado pela distensão dos pleuritos abdominais e eversão da bolsa anal, associada à vibração das asas, bem como a liberação de uma gotícula da região anal Da Silva et al 1985;Robacker & Hart 1985;Nation 1989;De Lima & Howse 1997). Além disso, o comportamento de A. sororcula aqui apresentado, corrobora com as informações publicadas por Da Silva et al (1985) para esta mesma espécie, que observaram os mesmos processos de sinalização e cortejamento exibidos pelos machos.…”

ABSTRACT. Sexual behavior of Anastrepha sororcula Zucchi (Diptera, Tephritidae) in laboratory. Anastrepha sororcula Zucchi, 1979, is a fruit fly species that can be considered a key pest to the production of guava (Psidium guajava L., 1758), fruit tree which has a wide distribution in Brazil. In view of the importance of this species as a natural pest of Brazilian horticulture and, considering the lack of data about its biology and behavior, the aim of this paper is to obtain information about the age of sexual maturation of A. sororcula in the laboratory and to describe its reproductive behavior. The males reached sexual maturity between 7 and 18 days after emergence, with most of the individuals becoming sexually mature between 10 and 13 days of age. They exhibited signalling behavior to the females, characterized by the distension of the pleural area of the abdomen, forming a small pouch on each side, and by the protrusion of a tiny membranous pouch of rectal cuticle that surrounds the anal area. During this display, the males produced rapid movements of vibration of the wings, producing audible sounds. A droplet was liberated from the anal area during the vibration movements of the wings. After attracting the females, the males accomplished a series of elaborated movements of courtship behavior. The females reached sexual maturation between 14 and 24 days after emergence, with the majority becoming sexually mature at 19 days. The daily exhibition of sexual activities was confined almost exclusively to the period of 16:00-17:30h. A. sororcula presented a sharp protandry pattern.

“…Virgin adult flies were separated by sex to avoid matting and consequently differences in spermstorage organs among females (Fritz, 2004). Individuals were submitted to the tests 11 days after adult emergence, when flies were reproductively mature (Lima and Howse, 1997) in order to reduce behavioral differences due to mature stage (Lima and Howse, 1997).…”

Cuticular Hydrocarbons of the South American Fruit Fly Anastrepha fraterculus: Variability with Sex and Age

et al. 2012

Insect cuticular hydrocarbons are usually species-specific mixtures and may serve for species and gender recognition. They are, therefore, widely used in the chemotaxonomy and zoogeography of various insect taxa. In order to provide a basic study for further comparative analyses of cuticular hydrocarbon (CHC) profiles of cryptic species hidden within the South American fruit fly Anastrepha fraterculus complex (Diptera: Tephritidae), we analyzed the composition of the CHCs and their production with respect to age and sex in a laboratory population from Tucuman, Argentina. Several techniques of gas chromatography with mass spectrometric detection have been used in order to develop a suitable method for CHC identification, i.e., GC-MS in EI mode, GC-MS in CI mode, and GC×GC/TOFMS. Our analyses revealed a complex profile of aliphatic hydrocarbons in both males and females, consisting predominantly of n-alkanes, methyl-branched alkanes, as well as of alkenes and alkadienes. In young individuals (up to about 5 days after emergence), the CHC profiles were similar in males and females. However, in older flies, these profiles diverged and became clearly sex-specific. The temporal dynamics of the CHC patterns in both sexes were evaluated using multivariate exploratory techniques.
