“…In addition, genes involved in the production of JH, which affects the expression of Vg in social insects (33,81), are downregulated in reproductive individuals of O. biroi (116). Interestingly, JH content does not differ between gamergates and workers in H. saltator (123) but is positively correlated with ovarian activity in Belonogaster longitarsus (69), another paper wasp species with a dominance hierarchy. Thus, in different species of social insects, JH can have opposite roles in regulating adult reproductive division of labor.…”

The study of insect social behavior has offered tremendous insight into the molecular mechanisms mediating behavioral and phenotypic plasticity. Genomic applications to the study of eusocial insect species, in particular, have led to several hypotheses for the processes underlying the molecular evolution of behavior. Advances in understanding the genetic control of social organization have also been made, suggesting an important role for supergenes in the evolution of divergent behavioral phenotypes. Intensive study of social phenotypes across species has revealed that behavior and caste are controlled by an interaction between genetic and environmentally mediated effects and, further, that gene expression and regulation mediate plastic responses to environmental signals. However, several key methodological flaws that are hindering progress in the study of insect social behavior remain. After reviewing the current state of knowledge, we outline ongoing challenges in experimental design that remain to be overcome in order to advance the field.

“…We asked next how CG9186 could alter the locomotor activity upon desiccation stress as well as the CHC composition. Given that the juvenile hormone (JH) signaling pathway regulates both the composition and abundance of CHCs of diverse arthropods (Kelstrup et al, 2014(Kelstrup et al, , 2017Lengyel et al, 2007) and was linked to the regulation of foraging behavior and locomotor activity (Meunier et al, 2007), the previously detected interaction between CG9186 and JH epoxide hydrolase (JHEH) enzymes (Kolkhof et al, 2017), which degrade JH in different tissues (L€ u et al, 2015;Tusun et al, 2017;Wojtasek and Prestwich, 1996), was of particular interest. The JHEH enzymes complement the activity of the secreted JH esterase, which degrades JH in the hemolymph (Kamimura et al, 2007;Kamita and Hammock, 2010;Vermunt et al, 1997).…”

“…This result was reminiscent of the finding that JH could mediate the threshold to social signals in turn. Given the gonadotropic and physiological functions of JH in the primitively social species (Amsalem et al, 2014;Kelstrup et al, 2017), a negative feedback loop exists between pheromones and JH to enhance the efficiency of regulation (Figure 1). Recent studies on parthenogenetic clonal raider ants (O. biroi) revealed the molecular mechanism underlying the brood control of reproductive skew.…”

The reproductive altruism in social insects is an evolutionary enigma that has been puzzling scientists starting from Darwin. Unraveling how reproductive skew emerges and maintains is crucial to understand the reproductive altruism involved in the consequent division of labor. The regulation of adult worker reproduction involves conspecific inhibitory signals, which are thought to be chemical signals by numerous studies. Despite the primary identification of few chemical ligands, the action modes of primer pheromones that regulate reproduction and their molecular causes and effects remain challenging. Here, these questions were elucidated by comprehensively reviewing recent advances. The coordination with other modalities of queen pheromones (QPs) and its context-dependent manner to suppress worker reproduction were discussed under the vast variation and plasticity of reproduction during colony development and across taxa. In addition to the effect of QPs, special attention was paid to recent studies revealing the regulatory effect of brood pheromones. Considering the correlation between pheromone and hormone, this study focused on the production and perception of pheromones under the endocrine control and highlighted the pivotal roles of nutrition-related pathways. The novel chemicals and gene pathways discovered by recent works provide new insights into the understanding of social regulation of reproductive division of labor in insects.
