“…Sexual recognition in dung beetles occurs through cuticular hydrocarbons (Ortiz-Domínguez et al, 2006). These compounds act as short-distance contact pheromones and vary according to several factors, such as the changes at the gonad level in females and males during reproduction (Halffter and López, 1977;Huerta et al, 1981;Martínez and Cruz, 1990;Martínez, 1992b;Martínez and Huerta, 1997;López-Guerrero and Halffter, 2000;Howard and Blomquist, 2005;Huerta and Martínez, 2008;Ginzel, 2010;Favila et al, 2012).…”

Dung beetles display complex reproductive behaviors involving sexual findings, sexual recognition, fighting for mates and food used for nesting, sperm competition, and parental care. Over the past 40 years, significant advances have been made regarding the knowledge of various aspects of the sexual and nesting behavior of Neotropical dung beetles. However, human activities modify the natural habitats of dung beetles at an alarming rate, affecting food availability and altering the ecological functions performed by the species in their different habitats. A deeper understanding of the reproductive behavior of dung beetles may contribute significantly in understanding the evolutionary diversification of these insects and their response to environmental changes. The present study reviews and analyzes studies regarding the sexual and reproductive behavior of Neotropical dung beetle species under field and laboratory conditions. We gathered 132 studies and 146 species; 42% of the available data were based on field observations, 23% on laboratory observations, 30% under both field and laboratory conditions, and 5% unspecified. Our review detected significant knowledge, geographic, and habitat gaps regarding the reproductive behavior of Neotropical dung beetles. Based on our findings, we propose future research goals and alternative methods to measure the behavioral responses of Neotropical dung beetles to the impacts of human activities.

“…intensity which has a considerably high level during the Cyclical changes in the appearance and volume of egg laying phase, decreased after the egg laying activity the CA have been observed in many insects. The volume completed in L. riparia (Juberthie and Caussanel, 1980), has often been used as a measure of the gland activity in 9-24 h after the egg laying activity in Galeruca tanaceti (Osorio et al, 1997;Huerta and Martinez, 2008). Just as, (Siew, 1965) and in 12-36 h in M. domestica (Adams et al, the CA volume has been used as a criterion to show the 1975).…”

“…Although, some authors demonstrated the presence of the NSM within the CA only a few of them provided some detailed account of the functional significance of the NSM in the CA. In some studies it was mentioned that CA also has correlation with egg maturation (Toyoda et al, 1999;Huerta and Martinez, 2008).…”

The purpose of this study is to examine the effects of neurosecretory material (NSM) in Corpus Allatum (CA) of endoparasitic Pimpla turionellae L. on reproduction. For this purpose, the egg maturation of the insect and the amount of the NSM in CA of the serial section of the brain were studied. Egg maturation was determined by measuring the terminal oocyte length. In order to determine the amount of the NSM in CA the neurosecretory granules of which were stained by paraldehyde fuchsin are considered. The egg maturation of P. turionellae have performed twice. The NSM intensity in CA continued increasingly from the first day of egg development until the first oviposition days; and reached the maximum level before the second egg maturation phase. These observations showed that the NSM in CA of this insect may be related to egg development.

“…A fascinating scientific problem, sex determination and differentiation may influence biological reproduction and cause sexual morphism. Gonochoristic animals are usually sexually dimorphic, which mainly involves body size (Ma et al, 2016; Wu et al, 2015), organ morphology (Huerta & Martínez, 2008; Okuda et al, 2002), hormones (Antica et al, 2002; Zimmerberg & Farley, 1993), and life expectancies (Shi et al, 2017). Teleosts are one of the most diverse groups of vertebrates (Sidlauskas & Chakrabarty, 2010), with almost 30,000 species, making them one of the most common vertebrates in the world today (Britz, 2017).…”

Hemibarbus maculatus is a globally important species for its value in fisheries and aquaculture. There is relatively little information available about this species' sexual development genes. Therefore, in this study, we used the technology of high‐throughput RNA sequencing (RNA‐seq), to investigate if the ovary and testis' differently expressed genes (DEGs) during sex differentiation in H. maculatus. Our results revealed a total of 43,468,248 and 39,241,362 qualified reads were generated in the female and male libraries, and 32,127 unigenes were assembled via the annotation analysis. Moreover, 17,808 unigenes were found to be DEGs between males and females, with 12,726 up‐ and 5082 downregulated genes in the ovaries and testes, respectively. The transcriptome analysis revealed there are 23 DEGs between ovary and testes of H. maculatus, which may be involved in sex determination. The expression patterns of these genes were validated by quantitative real‐time PCR (qPCR). The results of qPCR were generally consistent with the RNA‐seq results. This work was the first to annotate genes linked with gonadal development and reproduction in H. maculatus using gonadal transcriptome analysis, which provides useful molecular data for a better understanding of sexual development, as well as functional genomics and population genetics studies of H. maculatus.
