“…Esse é o caso de A. sororcula, A. fraterculus, A. turpiniae Stone, 1942e A. zenildae Zucchi, 1979, espécies crípticas que podem compartilhar o mesmo recurso, frutos de goiaba. Por serem espécies morfologicamente semelhantes, elas apresentam mecanismos pré-zigóticos bem caracterizados, com diferenças comportamentais marcantes que influenciam no reconhecimento específico, como os diferentes períodos de atividade sexual Dos Santos et al 2001). Verificou-se, portanto, uma tendência para maior atividade sexual de A. sororcula ao final do período vespertino.…”

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.

“…fraterculus is also noteworthy since these species mate readily in no-choice breeding experiments (Dos Santos et al 2001) yielding a pattern of codominance in relation to timing of mating in F 1 hybrids (F. Henning & S. R. Matioli, unpublished).…”

Horário de Cópulas de Anastrepha obliqua (Macquart) (Diptera: Tephritidae) em Condições de Laboratório RESUMO -O isolamento reprodutivo alocrônico parece ser um fator importante nos processos de especiação em Tephritidae, uma vez que a existência de horários de cópula específicos é uma característica comum de suas espécies. O horário de cópula de Anastrepha obliqua (Macquart) foi investigado usando observações segundo metodologia grupo-focal, durante dez dias, em condições de laboratório. O número de casais em cópula e de machos apresentando comportamento de chamado variou significativamente em relação ao horário do dia. As atividades sexuais mostraram-se concentradas no período vespertino, sendo que a chamada dos machos alcançou um pico entre 15:30h e 16:30h e as cópulas ocorreram mais freqüentemente entre as 14:00h e 16:30h. PALAVRAS-CHAVE: Isolamento alocrônico, especiação, comportamento sexualABSTRACT -Allochronic reproductive isolation seems to be an important factor in speciation processes in Tephritidae since specific mating times are a widespread feature of its species. The timing of matings of the West Indian fruit fly, Anastrepha obliqua (Macquart) was investigated through groupfocal observations, during ten days, under laboratory conditions. The number of observed matings and males exhibiting calling behavior varied significantly according to time of day. Sexual activities seemed to be concentrated in the afternoon period, with the male calling behavior reaching a peak between 3:30p.m. and 4:30p.m., and mating occurred most frequently from 2:00p.m. to 4:30p.m.

“…Hybrid flies are fertile (Yee and Goughnour 2011) and thus subject to selection pressures. Hybridization in Rhagoletis and other tephritid flies has been documented (dos Santos et al 2001, Schwarz et al 2005, Segura et al 2011, Rull et al 2012), but quantitative analyses of hybrid phenotypes have not been conducted or only marginally (Ebina and Ohto 2006). Based on studies of bees (Rinderer et al 1990) and vertebrates (Montanucci 1978, Ferguson and Danzmann 1987, McElroy and Kornfleld 1993, Nolte and Sheets 2005, Ackermann et al 2006, Speczlár et al 2009), it can be predicted that the size and shape of some R. pomonella X R. zephyria hybrids are intermediate, whereas others are more Kke those of one of the parental types.…”

Hybridization between apple maggot, Rhagoletis pomonella (Walsh), and Rhagoletis zephyria Snow (Diptera: Tephritidae) occurs in Washington State, complicating fly identifications. Here, experimentally generated Fj hybrids of R. pomonella and R. zephyria were classified using morphometric methods. Five of nine mean body size measurements of hybrids from crossing female R. pomonella X male R. zephyria were intermediate between those of nonhybrids. Aculeus lengths of hybrid females were intermediate or were more similar to those of R. pomonella than R. zephyria. Based on six or seven body size measures, 25.0% of female and 44.4% of male hybrids were correctly classified. Misclassiñed female and male hybrids resembled R. pomonella and one or the other parental species, respectively. Mean wing shapes of hybrid females based on landmark measurements were novel, whereas those of males were intermediate between those of nonhybrids. Based on wing shapes + natural log (ln) centroid size, 90.9% of female and 66.7% of male hybrids were correctly classified. Hybrid females were misclassified as R. pomonella and more hybrid males as R. zephyria. Based on surstylus shape, 27.7% of male hybrids were correctly classified, with more being misclassified as R. pomonella. Results show wing shape + ln centroid size is the most useful measure for identifying female and male hybrids and that R. pomonella traits for aculeus length and/or wing shape appear dominant to those of R. zephyria in hybrid females.
