Aspects of the reproductive behaviour and development of two forensically relevant species, Blaesoxipha (Gigantotheca) stallengi (Lahille, 1907) and Sarcophaga (Liopygia) ruficornis (Fabricius, 1794) (Diptera: Sarcophagidae) Rev. Bras. entomol.
Barbosa,Taciano Moura; Cruz,Marília Rafaela Pereira; Pontes,Wendel José Teles; Vasconcelos,Simão Dias.
Abstract We studied aspects of the reproductive behaviour and development of two species of Sarcophagidae (Diptera) of potential forensic importance, Blaesoxipha stallengi (Lahille, 1907) and Sarcophaga ruficornis (Fabricius, 1794), which are dominant in assemblages in dry forests in Northeastern Brazil. We described the behavioural acts associated with courtship and mating and estimated the development time (from egg/larva until adult) - of both species. Description of the reproductive behaviour was based on 50 couples of each species whereas 250 larvae were used for the estimation of the developmental time. A total of 55 successful copula were observed for B. stallengi and 142 for S. ruficornis. Pre-copulatory behaviour differed between the species, as...

Complex mating behavior in Adelosgryllus rubricephalus (Orthoptera, Phalangopsidae, Grylloidea) Iheringia, Sér. Zool.
Zefa,Edison; Martins,Luciano de P.; Szinwelski,Neucir.
We describe the mating behavior of Adelosgryllus rubricephalus Mesa & Zefa, 2004. In trials carried out in laboratory we verified the following mating sequence: (1) sexual recognition by antennation; (2) courtship with male turning his abdomen towards the female, performing mediolateral antennae vibration, jerking its body antero-posteriorly and stridulating intermittently, while receptive female drums on the male's abdomen tip, cerci and hind-tibia with her palpi or foretarsi; the male then stops and stays motionless for some seconds, extrudes the spermatophore and both restart the behavioral sequence described above; (3) copulation: male underneath female; with his tegmina inclined forward, and joins his genitalia to the female's to promote sperm...

Comportamento de corte, acasalamento e postura de Chelonus insularis (Hymenoptera: Braconidae) em ovos de Spodoptera frugiperda. Repositório Alice
REZENDE, M.A.A.; DELLA LUCIA, T.M.C.; CRUZ, I.; VILELA, E.F..
Procurou-se descrever, em laboratorio, o comportamento de corte, acasalamento e postura de C.insularis tendo S.frugiperda como hospedeiro. Dez casais de tres dias de idade foram individualizados em copos plasticos de 50ml de capacidade e observados para a descricao do comportamento. Verificou-se o inicio da sequencia de corte quando o macho toca suas antenas em qualquer parte do corpo da femea. A partir dai, movimenta suas antenas com grande frequencia, bate asas, desloca-se rapidamente e assume a posicao de copula, que consiste na sua monta sobre a femea. Esta permanece em posicao normal de caminhamento, porem sem se mover. (Femeas receptivas apresentaram poucos batimentos de asas e antenas. Em 20% das observacoes, a cabeca do macho ficava em posicao...

Courtship and mating of Scorpiops luridus Zhu Lourenço & Qi, 2005 (Scorpiones: Euscorpiidae) from Xizang province, China J. Venom. Anim. Toxins incl. Trop. Dis.
Jiao,GB; Zhu,MS.
In the current work, the courtship and mating of Scorpiops luridus Zhu Lourenço & Qi, 2005 (Euscorpiidae) from Xizang province (Tibet), China, were studied for the first time in the laboratory. Most of the mating behaviors in Scorpiops luridus are not remarkably different from those exhibited by other scorpions. However, for the first time a male pulling a female with its chelicerae to rapidly accomplish the sperm uptake was observed. Additionally, the sexual stinging behavior displayed by the male occurred in the initial stage, not during the promenade stage as previously described in several scorpion species. Through observation and analysis, we speculate that venom injection during sexual stinging is selective, possibly relying on the status...

El comportamiento acústico de Fenestra bohlsii Giglio-Tos (Orthoptera: Acrididae: Gomphocerinae) Neotropical Entomology
Lorier,Estrellita; Clemente,Maria E; García,Maria D; Presa,Juan J.
The acoustic behavior of Fenestra bohlsii Giglio-Tos is described for the first time. The sounds and behaviors were observed and registered in captivity. The signals were digitized with the Sound-Blaster AWE64 Gold program and analysed with the Avisoft SAS Lab Pro 30 PC for MS Windows software. Seven different types of sounds are described as produced by males: spontaneous song (also used during the courtship), two different types of courtship song, assault song, tapping associated to the courtship, interaction between males and fly crackling. For each one, the characteristic oscillograms and frequency spectra are given. Sounds are produced by different mechanisms: femoro-tegminal stridulation, typical for Gomphocerinae, fly crackling, hind tarsi tapping...

Frequency of spermatophore production and regeneration in the males of Tityus (Atreus) magnimanus Pocock, 1897 (Scorpiones, Buthidae) J. Venom. Anim. Toxins incl. Trop. Dis.
Ross,LK.
The frequency of spermatophore production and the amount of time between matings for laboratory-reared males of Tityus (Atreus) magnimanus to regenerate spermatophores were examined. Males attain sexual maturity at the fifth or sixth instar (after a period of 137 to 155 days) and can produce initial spermatophores shortly after maturation. After mating, males can regenerate spermatophores within a single 24-hour period and remate. The present contribution represents the first report on an aspect of reproductive biology in this species and is part of a continuing study of the life history and post-embryonic development of Tityus (Atreus) magnimanus.

Is more better? Sexual confusion during courtship between two sympatric and synchronic tarantulas: Acanthoscurria suina and Eupalaestrus weijenberghi Rev. Bras. Zool.
Costa,Fernando G.; De Oca,Laura Montes; Perdomo,Cintya; Ortiz-Villatoro,David; Baruffaldi,Luciana; Pérez-Miles,Fernando.
When two similar species co-occur in time and space, strong mechanisms isolating them from each other are expected. Acanthoscurria suina Pocock, 1903 and Eupalaestrus weijenberghi (Thorell, 1894) are two sympatric and synchronic tarantulas that inhabit burrows in Uruguay's meadows. Here we test how and when reproductive isolation operates between these species. We exposed females of each species simultaneously to two males: either one male of each species, or two males of the same species. Males courted females of both species. Contrary to expectations, however, females of A. suina responded more effusively to heterospecific than to conspecific males, whereas females of E. weijenberghi only responded to conspecific males. Clasping (prelude of mating) was...

Mating behavior and female accompaniment in the whiptail lizard Cnemidophorus ocellifer (Squamata, Teiidae) in the Caatinga region of northeastern Brazil Biota Neotropica
Ribeiro,Leonardo Barros; Gogliath,Melissa; Sales,Raul Fernandes Dantas de; Freire,Eliza Maria Xavier.
We report here a set of observations on mating behavior and female accompaniment by the whiptail lizard Cnemidophorus ocellifer in an area of Caatinga (xerophilous open forests) in the state of Rio Grande do Norte, northeastern Brazil. We observed a stationary male lizard performing repeated vibratory movements of the pelvis and tail base upon the sandy soil. Since that male was in front of a burrow in which a female of the same species was sheltered, we hypothesize that this behavior may be part of a courtship display. We continued the observation and later, when the female emerged from the burrow, the male climbed on her and the copulation occurred. The incident of accompaniment observed was characterized by one male continuously accompanying a female...

Mating behaviour of the groundwater copepod Parastenocaris phyllura Kiefer, 1938 (Copepoda: Harpacticoida) Naturalis
Glatzel, Thomas; Schminke, Horst Kurt.
In the course of a cohort study of Parastenocaris phyllura several matings were observed under a microscope and recorded on video. In Parastenocaris phyllura no “precopulatory mate guarding” was found. Each mating behaviour comprises three phases and lasts for about 15 minutes, during which time the male actively moves its antennulae and antennae, pereiopods 1, 2, 3, 4, and furcal rami. The female is held in a characteristic position by the male and is entirely passive during the process.

Nest deprivation and mating success in Nile tilapia (Teleostei: Cichlidae) Zoologia
Mendonça,Francine Z.; Gonçalves-de-Freitas,Eliane.
We tested the effect of nest deprivation on the mating success and sexual selection of dominant Nile tilapia males in two treatments, consisting of two males and three females kept on aquarium with or without nesting substrate (INS: with substrate inside, N = 9; NOS: non-substrate inside, N = 11). Other male traits potentially affecting mating success, such as aggressiveness level, courtship investment, and condition factor were also analyzed. The dominant male's behavior was video-recorded in four 20-min sessions: 1, 4, 7, and 10 days after grouping. Latency to spawn and spawning frequency were similar in WS and NS groups, showing the same mating success among dominant males on the presence or absence of gravel. Nest investment was the main factor related...

Novel sex-related characteristics of the longsnout seahorse Hippocampus reidi Ginsburg, 1933 Neotropical Ichthyology
Oliveira,Tacyana P. R; Castro,André L. C; Rosa,Ierecê L.
This paper presents novel sex-related characteristics in Hippocampus reidi, expressed as a prominent and pigmented keel (males only), and by a row of dorsolateral spots mostly (97.4%) found in males. While the keel was found even in the smallest males sampled, the dorsolateral spots appear to be associated with body size. Ex situ observations revealed that during courtship males highlighted both characters by turning pale their background body colour. Understanding such colour and behavioural patterns is relevant to increase our knowledge about sexual selection in a morphologically and biologically unique group of fishes.

Reproductive behavior and parental roles of the cichlid fish Laetacara araguaiae Neotropical Ichthyology
Teresa,Fabrício Barreto; Freitas,Eliane Gonçalves-de.
We described the reproductive behavior of the small South American cichlid Laetacara araguaiae in streams from Brazil. We predicted that this species will show reproductive cooperation and division of labor between males and females in a similar way presented by other substrate-spawner cichlids. Thus, we studied 34 pairs in the pre-spawning (n = 11), egg/wriggler (n = 11) and fry (n = 12) phases. In the pre-spawning phase both sexes become involved in nest building and territorial defense, but females emphasizes building nest (p = 0.03), while males invest more time in territorial defense (p = 0.04). After spawning, male and female alternate between rearing eggs and defending nest in the territory. In the egg/wriggler phase females devotes more time...

Reproductive behavior in the annual fish Austrolebias reicherti Loureiro & García 2004 (Cyprinodontiformes: Rivulidae) Neotropical Ichthyology
García,Daniel; Loureiro,Marcelo; Tassino,Bettina.
Annual fishes inhabit temporary ponds that dry out seasonally and the adaptations to survive this extreme condition include high metabolic rates and an elaborate courtship behavior which ends in the deposition of drought-resistant eggs, capable of going through diapause stages in the substrate. The pronounced sexual dimorphism that these fishes show suggests that sexual selection could play a key role in the differentiation, speciation and evolution of this diverse group of fishes. However, there is scarce information about their reproductive isolation mechanisms, including detailed analysis of courtship signals. Herein, we analyzed, qualitatively and quantitatively, the reproductive behavior of Austrolebias reicherti. The behavioral units recognized in...

Reproductive behavior of intertidal hermit crabs (Decapoda, Anomura) in southeastern Brazil Zoologia
Turra,Alexander.
The reproductive behavior of four intertidal hermit crab species [Clibanarius antillensis Stimpson, 1859, C. sclopetarius (Herbst, 1796), C. vittatus (Bosc, 1802), and Pagurus criniticornis (Dana, 1852)] was studied in São Sebastião Channel, southeastern Brazil. The overall behavior followed previous descriptions for Diogenid and Pagurid hermit crabs but some particular differences were recorded. Male to male agonistic encounters over females and guarding behavior were more common to C. sclopetarius, C. vittatus, and Pagurus criniticornis. During guarding, males clearly grasped females' chelipeds, eyestalks, and the margins of their shell apertures. This oblique guarding and, simultaneously, accessing behavior (OGAP) has never been described for hermit...

Reproductive behavior of the mangrove crab Ucides cordatus (Crustacea; Brachyura; Ucididae) BABT
Linhares,Jussiara Candeira Spíndola; Silva,José Roberto Feitosa.
The aim of the present work was to study the reproductive behavior of the mangrove crab (Ucides cordatus) in the estuary of the Igaraçú River (Piauí, Brazil). Courtship and mating were observed in December 2007 and in January-March 2009. The most frequently observed reproductive behavior was the transference of eggs onto the abdomen of the female. Some disputes between males and some copulations were observed. The males mated with more than one female each night and all mating activity occurred at night. The establishment of a closed season coinciding with the mating season represented an effective strategy for the preservation of the species when the socioeconomic situation of the community of gatherers was taken into account.

Reproductive success and female preference in the amazonian cichlid angel fish, Pterophyllum scalare (Lichtenstein, 1823) Neotropical Ichthyology
Cacho,Maria do Socorro R. F.; Chellappa,Sathyabama; Yamamoto,Maria Emília.
The angel fish, Pterophyllum scalare is a cichlid native to the Amazon Basin of Brazil and is exported as an ornamental fish. In this study the importance of the experience and previous reproductive success of males in mate selection was investigated. In order to investigate reproductive experience, six pairs of males (experienced and inexperienced) and six females were used. Males were placed in an aquarium, where one female was released. Mate selection was verified by the time spent by a female near one of the males. To evaluate reproductive success, six pairs of males were tested, each pair consisting of a successful male and an unsuccessful one. Again, time spent with one of the males was considered as an indication of preference by the female. Each...

Visual communication stimulates reproduction in Nile tilapia, Oreochromis niloticus (L.) BJMBR
Castro,A.L.S.; Gonçalves-de-Freitas,E.; Volpato,G.L.; Oliveira,C..
Reproductive fish behavior is affected by male-female interactions that stimulate physiological responses such as hormonal release and gonad development. During male-female interactions, visual and chemical communication can modulate fish reproduction. The aim of the present study was to test the effect of visual and chemical male-female interaction on the gonad development and reproductive behavior of the cichlid fish Nile tilapia, Oreochromis niloticus (L.). Fifty-six pairs were studied after being maintained for 5 days under one of the four conditions (N = 14 for each condition): 1) visual contact (V); 2) chemical contact (Ch); 3) chemical and visual contact (Ch+V); 4) no sensory contact (Iso) - males and females isolated. We compared the reproductive...
