AbstractNew observations on parental behavior of the earwig, Forficula auricularia L., are reported and the literature on the parental behavior in the Dermaptera is summarized. The construction of the nest, care of the eggs and nymphs, and the duration of parental care are described. The control of parental behavior and the role of the male in nest establishment are also considered.

The Relationship

AbstractSong rates in male blackcaps were examined over the course of the breeding season and compared with various aspects of mating and later parental behavior in individual birds. Song rates decreased steadily over the breeding season although relative individual rates remained constant. Early territory holders sang more and mated faster than late-comers. Song frequency was positively related to alarm call frequency during nesting but negatively related to male incubation and offspring feeding rates. Surprisingly, under the conditions studied, higher song rates were indicative of higher nesting success. This demonstrates the potential role of song frequency in the advertisement of territorial quality. There may well be either environmentally dependent differences in parental care as adaptations to temperature, food or predation pressure or simply a trade-off for males between singing and parental care, where early arriving males derive greater fitness benefits from singing, while late arriving males benefit more from engaging in parental care.

Plastic Trait

Many behaviors of insects are stimulated, modified, or modulated by hormones. The principal hormones involved are the same as the ones that control moulting, metamorphosis, and other aspects of development, principally ecdysone and juvenile hormone. In addition, a small handful of neurosecretory hormones are involved in the control of specific behaviors. Because behavior is a plastic trait, this chapter begins by outlining the biology and hormonal control of phenotypic plasticity in insects, and how the hormonal control of behavior fits in with other aspects of the control of phenotypic plasticity. The rest of the chapter is organized around the diversity of behaviors that are known to be controlled by or affected by hormones. These include eclosion and moulting behavior, the synthesis and release of pheromones, migration, parental care, dominance, reproductive behavior, and social behavior.

The Relationship

Research investigating the neural substrates underpinning parental behaviour has recently gained momentum. Particularly, the hypothalamic medial preoptic area (MPOA) has been identified as a crucial region for parenting. The current study conducted a scientometric analysis of publications from 1 January 1972 to 19 January 2021 using CiteSpace software to determine trends in the scientific literature exploring the relationship between MPOA and parental behaviour. In total, 677 scientific papers were analysed, producing a network of 1509 nodes and 5498 links. Four major clusters were identified: “C-Fos Expression”, “Lactating Rat”, “Medial Preoptic Area Interaction” and “Parental Behavior”. Their content suggests an initial trend in which the properties of the MPOA in response to parental behavior were studied, followed by a growing attention towards the presence of a brain network, including the reward circuits, regulating such behavior. Furthermore, while attention was initially directed uniquely to maternal behavior, it has recently been extended to the understanding of paternal behaviors as well. Finally, although the majority of the studies were conducted on rodents, recent publications broaden the implications of previous documents to human parental behavior, giving insight into the mechanisms underlying postpartum depression. Potential directions in future works were also discussed.

SummaryIn spite of the comparative rarity of anorexia nervosa in African patients, the case of a young black Zimbabwean woman which fulfils Feighner's diagnostic criteria is presented. Special reference is made to several unusual features which include the social and psychological conflicts engendered by changes of culture, the clinical symptoms, and the role of a traditional healer in her recovery. A speculative hypothesis concerning aetiology is suggested.
