Courtship behavior and spawning of the hairy blenny Labrisomus nuchipinnis (Labrisomidae) in southeastern Brazil Neotropical Ichthyology
Gibran,Fernando Zaniolo; Santos,Flávia Borges; Santos,Hertz Figueiredo dos; Sabino,José.
Labrisomus nuchipinnis is a diurnal bottom-dwelling sit-and-wait carnivorous fish that inhabits holes and rifts of rocky areas in tropical shallow waters. Here we report on the courtship behavior and spawning of this hairy blenny in southeastern Brazil, with a detailed description and comparison with other Blennioidei. Labrisomus nuchipinnis is a territorial species that was observed courting with more than one female, and presenting a well defined pattern cycle related to reproductive behavior and paternal egg care. Adhesive demersal eggs are laid on small algae-covered rocks at sites with increased current velocity within the male's territory, which may enable higher egg survivorship and shorter developmental time.

Life history of Aneugmenus merida Smith (Hymenoptera: Tenthredinidae) in the Venezuelan Andes Neotropical Entomology
Avila-Núñez,Jorge L.; Daniel Otero,Luis; Silmi,Sobeida; Calcagno-Pisarelli,Maria P..
Details of the life cycle of Aneugmenus merida Smith (Hymenoptera: Tenthredinidae) reared under laboratory conditions are reported. Females may produce parthenogenetic or non-parthenogenetic eggs. After eclosion, males of A. merida go through five larval instars, pre-pupa, pupa and imago. The complete life cycle lasts approximately 44 days. Larvae feed on bracken [Pteridium caudatum (L.) and Pteridium arachnoideum (Kaulf)] (Dennstaedtiaceae). We also report on morphological observations of the sinus sexualis in males by scanning electron micrographs and give details on mating behavior.

Mating systems in caridean shrimp (Decapoda: Caridea) and their evolutionary consequences for sexual dimorphism and reproductive biology RChHN
CORREA,CRISTIÁN; THIEL,MARTIN.
In this paper we review functional and evolutionary relationships among mating systems of caridean shrimp and specific traits such as general biology/ecology, sexual systems, behavior and morphology. Four mating systems are described based on reports from available literature, and a fifth system is recognized but published information is insufficient to describe it in detail. `Monogamy' occurs in many species inhabiting monopolizable refuges or hosts, especially when environmental conditions restrict the probability of intraspecific interactions. In contrast, free-living species experience higher encounter rates and males can dominate or search. In `neighborhoods of dominance' mating systems, large males have higher reproductive success since they perform...

Sexual behavior of the navel OrangeWorm, Amyelois transitella (Walker) (Lepidoptera: Pyralidae) Neotropical Entomology
Parra-Pedrazzoli,Ana Lia; Leal,Walter S..
To get a better understanding of the mating behavior of the navel orangeworm, Amyelois transitella (Walker), we developed a robust laboratory colony derived from larvae collected in Bakersfield, California and fed on dried, roasted pistachio. In the lab at 25ºC, most of the mating activity was observed during the last hour of the scotophase and for the first 30 min of the photophase. Female calling was characterized by the abdomen being protruded between the wings with the distal segments perpendicular to the body and exposing a pheromone gland, as well as by continuous antennation. Males approached calling females from a short distance by displaying wing fanning and antennation. When a male antennated on a calling female's abdomen, she either accepted the...

Territórios de machos, acasalamento, distribuição e relação com plantas em Protomeliturga turnerae (Ducke, 1907) (Hymenoptera, Andrenidae) Rev. Bras. entomol.
Medeiros,Petrúcio C. R. de; Schlindwein,Clemens.
Protomeliturga turnerae (Ducke, 1907) represents the monotypic tribe Protomeliturgini (Andrenidae, Panurginae). The species is oligolectic on flowers of Turnera L. (Turneraceae). A survey of bees on flowers of Turneraceae and of material in entomological collections showed that P. turnerae is common and endemic in Northeastern Brazil, occurring from the State of Maranhão to Alagoas. In João Pessoa, Paraíba, we studied the reproductive biology and mating behavior of P. turnerae and its relations to plants. At the study site, the species was univoltine with males emerging 5-8 days before the females. Soon after emergence the males established territories on flowers of Turnera subulata Smith which they occupied during several days. Parts of each territory...

The influence of sex ratio on the reproduction of pirarucu, Arapaima gigas, in captivity. Repositório Alice
LIMA, A. F..
Because sex ratio in the broodstock can influence the reproductive behaviour of a species, the influence of sex ratio on the reproductive success of pirarucu, Arapaima gigas, in captivity was assessed. Pirarucu breeders were stocked in 0.10-0.13 ha earthen ponds at three sex ratios in quadruplicate: one male to one female (1M1F); one male to two females (1M2F); and two males to one female (2M1F). Eight spawning events occurred, seven of them with the 1M1F sex ratio, which was the most successful of the three tested sex ratios.
