Spiders in the family Lycosidae are known for their hunting ability and maternal care behaviors. Predation on newly hatched spiderlings (pulli) by mother spiders decreases when they come into contact, and they carry the pulli on their dorsal surface. However, the factors inducing maternal care in lycosid spiders have not been elucidated. In this study, we investigated maternal care in <jats:italic>Pardosa pseudoannulata<\/jats:italic> (Araneae, Lycosidae) females. We proposed that the physical interaction between pulli and mother spiders induces maternal care via <jats:italic>m<\/jats:italic>\u2010aminophenylacetylene (<jats:italic>m<\/jats:italic>\u2010A), a novel regulator of maternal care. The presence of pulli on the dorsal abdomen of non\u2010mother spiders suppressed pulli predation and increased the pulli\u2010carrying rate, and the absence of pulli on the mother spiders increased pulli predation and decreased the pulli\u2010carrying rate. The compound <jats:italic>m<\/jats:italic>\u2010A was abundant in mother spiders, and it could be induced in non\u2010mother spiders when they carried pulli. The topical application of <jats:italic>m<\/jats:italic>\u2010A to non\u2010mother spiders and <jats:italic>m<\/jats:italic>\u2010A injection decreased pulli predation and increased the pulli\u2010carrying rate, respectively; these findings indicate that <jats:italic>m<\/jats:italic>\u2010A in both internal tissues and the integument is required for the induction of maternal care behavior, and the interaction between pulli and females induces the production of <jats:italic>m<\/jats:italic>\u2010A. In\u2010depth study of the regulatory mechanism of maternal care will enhance our understanding of spider biology and behavior.<\/jats:p>","DOI":"10.1111\/1744-7917.13329","type":"journal-article","created":{"date-parts":[[2024,2,7]],"date-time":"2024-02-07T08:07:26Z","timestamp":1707293246000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["<i>m<\/i>\u2010Aminophenylacetylene
