13. Body size, symmetry and courtship behavior of Dysdercus maurus distant (Hemiptera: Pyrrhocoridae)
This study analyses the role of body size and symmetry in the sexual selection and courtship behavior of Dysdercus maurus Distant. Sexual conflicts signaled by coercive mating, female resistance, and pre-copulation fights illustrate the mating system. Male-female struggles were observed in all mating attempts. Females tried to reject males by pushing or runn

14. Presentes nupciais em Paratrechalea ornata Carico, 2005 (Araneae; Trechaleidae) : quais os canais de sinalização reconhecidos pelas fêmeas no contexto pré-copulatório?
The Order Araneae is widely known for having a great variety both in terms of morphology and behavior, from which I highlight the genus Paratrechalea Carico, 2005, whose males construct a nuptial gift from a prey wrapped in silk that is offered to the female during courtship. Recent studies indicate that this gift-giving behavior in spiders represents a male

15. Interações tritróficas entre Diatraea flavipennella (Lepidoptera: Crambidae), Saccharum officinarum (Poales: Poaceae) e Cotesia flavipes (Hymenoptera: Braconidae) e atividade antifúngica de compostos produzidos por Atta spp. (Hymenoptera: Formicidae) / Tritrophic interactions between Diatraea flavipennella (Lepidoptera: Crambidae), Saccharum officinarum (Poales: Poaceae) and Cotesia flavipes (Hymenoptera: Braconidae) and antifungal activity of compounds produced by Atta spp. (Hymenoptera: Formicidae)
Aiming to study the reproductive behaviour of Diatraea flavipennella Box, 1931 (Lepidoptera: Crambidae) in the presence and absence of three different varieties of sugarcane plants, the searching behavior of Cotesia flavipes (Hymenoptera: Braconidae) for larvae of D. flavipenella in non-infested and D. flavipennella infested sugarcane plants, the olfactive r

16. El comportamiento acústico de Fenestra bohlsii Giglio-Tos (Orthoptera: Acrididae: Gomphocerinae)
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 mal

17. Copulatory courtship song in Lutzomyia migonei (Diptera: Psychodidae)
Lutzomyia migonei is a vector of leishmaniasis with a wide distribution in South America, which could favour population differentiation and speciation. Cryptic species of the Lutzomyia longipalpis complex, the widely distributed sand fly vector of visceral leishmaniasis in Latin America, have previously been shown to display distinct copulation songs. We fou

18. Courtship and mating of Scorpiops luridus Zhu Lourenço & Qi, 2005 (Scorpiones: Euscorpiidae) from Xizang province, China
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

19. Cynolebias parnaibensis, a new seasonal killifish from the Caatinga, Parnaíba River basin, northeastern Brazil, with notes on sound producing courtship behavior (Cyprinodontiformes: Rivulidae)
Cynolebias parnaibensis, da drenagem do rio Canindé, bacia do rio Parnaíba, nordeste do Brasil, é descrita. Ela é considerada um membro de um clado endêmico da Caatinga. O clado é diagnosticado, e. g., por uma série de modificações estruturais do aparato mandibular faringiano, que está relacionado à produção de som exibida por machos durante o c

20. Visual communication stimulates reproduction in Nile tilapia, Oreochromis niloticus (L.)
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 g

21. Notes and observations on courtship and mating in Tityus (Atreus) magnimanus Pocock, 1897 (Scorpiones: Buthidae)
Courtship and mating behaviors of the scorpion Tityus (Atreus) magnimanus are herein described, consisting of various components that pertain to four distinct behavioral stages. The courtship and mating rituals of Tityus (Atreus) magnimanus are similar to those of other scorpions. Behavioral components are presented in an ethogram to demonstrate their occurr

22. Genetic divergence between two sympatric species of the Lutzomyia longipalpis complex in the paralytic gene, a locus associated with insecticide resistance and lovesong production
The sandfly Lutzomyia longipalpis s.l. is the main vector of American Visceral Leishmaniasis. L. longipalpis s.l. is a species complex but until recently the existence of cryptic sibling species among Brazilian populations was a controversial issue. A fragment of paralytic (para), a voltage dependent sodium channel gene associated with insecticide resistance

23. Reproductive isolation between sympatric and allopatric Brazilian populations of Lutzomyia longipalpis s.l. (Diptera: Psychodidae)
Lutzomyia longipalpis s.l., the main vector of Leishmania chagasi in Latin America, is a species complex although the exact number of siblings is yet unknown. In Brazil, the siblings differ in male copulatory courtship songs and pheromones that most certainly act as pre-zygotic reproductive barriers. Here we analysed the reproductive isolation between three

24. More about the role of 2,6-dichlorophenol in tick courtship: identification and olfactometer bioassay in Amblyomma cajennense and Rhipicephalus sanguineus
This study aimed to identify 2,6-dichlorophenol (2,6-DCP) in Amblyomma cajennense and to evaluate its role in A. cajennense and Rhipicephalus sanguineus courtship. Hexanic extract from attractive females was purified by solid phase extraction and the phenol was identified by the single ion monitoring method using GC/MS. In an olfactometer, the responses of A
