Complex mating behavior in Adelosgryllus rubricephalus (Orthoptera, Phalangopsidae, Grylloidea)
Provedor de dados: 76
Autores: Zefa,Edison; Martins,Luciano de P.; Szinwelski,Neucir.
We describe the mating behavior of Adelosgryllus rubricephalus Mesa &amp;amp; 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...

Técnicas de manejo reprodutivo em bovinos de corte.
Provedor de dados: 14
Autores: VALLE, E. R. do; ANDREOTTI, R.; THIAGO, L. R. L. de S.
Na pecuária de corte, a exploração comercial do sistema de cria se constitui na fase do sistema produtivo, que envolve a criação e o manejo não só das matrizes bovinas e seus respectivos bezerros ate a desmama, mas também das novilhas de reposição e dos touros. Esse sistema tem por objetivo a produção de bezerros desmamados que representa a maior fonte de receita do criador. A venda de vacas descartadas e outros animais, apesar de contribuírem para a produção total, e uma fonte de receita marginal, mas também muito importante para o criador. Portanto, a viabilidade do sistema vai depender da eficácia e eficiência com que são utilizados os meios disponíveis para a otimização da produtividade. O escopo deste trabalho foi o de apresentar e discutir as...

Touros melhoradores ou inseminação artificial: um exercício de avaliação econômica.
Provedor de dados: 14
Autores: AMARAL, T. B.; COSTA, F. P.; CORRÊA, E. S.
A pecuária de corte é uma atividade complexa, que envolve um grande número de variáveis. Dentre as decissões a tomar, destacam-se aquelas ligadas à área de reprodução, começando com a escolha entre monta natural e inseminação artificial. Por seu turno, diversas opções estão disponíveis em cada um desses processos. Quanto à monta natural, é preciso definir a qualidade e, consequentemente, o preço a pagar pelos touros. Na opção por inseminação, há alternativas quanto ao valor genético e preço do sêmen, além da possibilidade de realizar a sincronização de cio das fêmeas. Este trabalho discute os aspectos econômicos da decisão relacionada com o uso de monta natural ou inseminação artificial, bem como analisa o impacto no sistema de produção de variáveis, como...

Precopulatory mate guarding in copepods
Provedor de dados: 16
Autores: Boxshall, Geoffrey A.
In many copepod species adult males clasp females for an extended period before transferring spermatophores. Clasping juvenile females (first to fifth copepodid inclusive) is interpreted as mate guarding and is shown to be widespread among podoplean copepods. It is distinct from copulation, which takes place only between adults and is often distinguishable from mate guarding by a difference in clasping posture.

Evasive mating behaviour by female nurse sharks, Ginglymostoma cirratum (Bonnaterre, 1788), in an equatorial insular breeding ground
Provedor de dados: 83
Autores: Afonso,André S.; Cantareli,Carlos V.; Levy,Rafael P.; Veras,Leonardo B.
ABSTRACT Mating events and aggregations of vulnerable nurse sharks Ginglymostoma cirratum were recorded in the insular protected area of Fernando de Noronha (FEN), Brazil, between April and August 2015. Female sharks were observed clustering in groups of up to 14 individuals in shallow water adjacent to the shore. Several evasive mating behaviours in the presence of males were noticed, including shoreward movement, positioning ventral side up at the sea surface with emerged pectoral and pelvic fins, body rolling and caudal fin thrashing. Fresh bite marks indicative of male courtship and coupling attempts were visible in female's pectoral and caudal fins. Altogether, the observed behaviours match previous reports of non-cooperative female nurse sharks...

It is well-known that there are considerable strain differences in the relative copulation rates between male and superovulated female mice. In particular, the C57BL/6J strain of mice has a lower rate of successful copulation. We examined the effect of exposure to an electric field on sexual behavior in C57BL/6J male mice. When C57BL/6J males were exposed to a 50 Hz, 45 kV/m electric field for 30 min per day for 11 days and placed in a cage with a superovulated female of the same strain, the successful copulation rates of males was significantly improved compared with unexposed males (P&lt;0.05). These results suggest that the exposure of C57BL/6J male mice to an electric field improves their sub-fertility activity in mating with superovulated females.

Sexual behavior of the digger wasp Sphex ingens Smith (Hymenoptera, Sphecidae)
Provedor de dados: 92
Autores: Souza,Carlos Alberto S.; Prezoto,Fábio; Lima,Mauro Sérgio C.S.; Pederassi,Jonas.
A species' mating system depends on its spatial distribution and temporal availability of mating opportunities, as well as on the resources that create these opportunities. In addition, for many species, courtship is driven by specific behaviors that precede and follow copulation. Although Sphex ingens is a taxonomically well known species of digger wasp, its ecology and behavior remain poorly known. Hence, we analyzed patterns and trends of sexual behavior, in order to understand whether courtship can persist in a polygamous mating system. We monitored by video wasp populations in Ilha Grande, southeastern Brazil. Based on the observed behaviors, we calculated stochastic probabilities with a Markov chain to infer on behavioral trends. We recorded four...

Relationships between physiological and behavioral responses of goat bucks in mating season
Provedor de dados: 96
Autores: Karaca,Serhat; Yılmaz,Ayhan; Ser,Gazel; Sarıbey,Muammer.
ABSTRACT The objective of this study was to determine the sexual parameters in young bucks with different sexual activity and the effect of experience (age) on sexual parameters in bucks. Fifteen young, sexually inexperienced (SI) and five adult, sexually experienced (SE) Saanen × Hair goat crossbred bucks were used in this study. Bucks were individually exposed to three estrus does for 15-min periods during four sexual performance tests, which were carried out every other day to determine some sexual behavior traits such as flehmen response, reaction time, and ejaculation efficiency. Sexually inexperienced young bucks were evaluated based on their sexual activity (active (AC) vs inactive (IA)) and presence of horn. It was found that AC bucks had...

Mating, ovipositional rhythm and fecundity of Nezara viridula (L.) (Heteroptera: Pentatomidae) fed on privet, Ligustrum lucidum Thunb., and on soybean, Glycine max (L.) Merrill fruits
Provedor de dados: 44
Autores: Panizzi,Antônio R.; Mourão,Ana P.M.
Laboratory studies were conducted on mating, ovipositional rhythm, and fecundity of the southern green stink bug, Nezara viridula (L.) fed on immature fruits of privet, Ligustrum lucidum Thunb. and soybean, Glycine max (L.) Merrill. A greater number of pairs were observed mating on privet (27 to 37 %) than on soybean (22 to 23 %). The preoviposition period was significantly shorter when females fed on privet (15.5 days) than when they fed on soybean (23.9 days). The intervals of time between the first four ovipositions, and between the 1st and the 4th oviposition were shorter on privet than on soybean (range of 1.9 to 3.3 days less on the former food). Greater percentage of females N. viridula oviposited and showed greater fecundity on privet than on...

Calling behaviour and evaluation of sex pheromone glands extract of Neoleucinodes elegantalis Guenée (Lepidoptera: Crambidae) in wind tunnel
Provedor de dados: 44
Autores: Eiras,Álvaro E.
Adult emergence and mating behavior of Neoleucinodes elegantalis Guenée were studied under laboratory conditions (23 ± 1°C, 12 h photophase and 70% RH). Adult emergence occurred only at scotophase period. Female began to emerge from the 1st hour to 8th hour with a peak occurring at 4th hour of scotophase. Male showed similar trend, but emerging from 2nd to 11th with a peak also at 4th hour of scotophase. Mating was preceded by wing vibration in the male prior to and during walking approach. Mating occurred only during the scotophase period between the 4th and 10th hour of scotophase, with the peak occurring at the 7th hour. Newly emerged N. elegantalis couples rarely mated (2.8%) whereas 48 and 96 h old couples mated 26.3% and 27.5% respectively. Glands...
