As a consequence, males have\n evolved a variety of methods, such as the transfer of inhibitory\n substances from their accessory glands, to ensure exclusive paternity\n of the female's offspring, generally with detrimental effects on\n female fitness. Inhibitory substances have been identified as peptides\n or other specific molecules. Unfortunately, in social insects\n male-mating traits are investigated only poorly, although male social\n insects might have the same fundamental influence on female-mating\n behavior as found in other species. A recently developed technique for\n the artificial insemination of bumblebee queens allowed us to\n investigate which chemical compound in the mating plug of male\n bumblebees,\n                    <jats:italic>Bombus terrestris<\/jats:italic>\n                    L., prevents females\n (queens) from further mating. Surprisingly, we found that the active\n substance is linoleic acid, a ubiquitous and rather unspecific fatty\n acid. Contrary to mating plugs in other insect species, the bumblebee\n mating plug is highly efficient and allows the males to determine\n queen-mating frequencies.\n                  <\/jats:p>","DOI":"10.1073\/pnas.061027998","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T10:36:44Z","timestamp":1027679804000},"page":"3926-3928","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":138,"title":["A nonspecific fatty acid within the bumblebee mating plug prevents females from remating"],"prefix":"10.1073","volume":"98","author":[{"given":"Boris","family":"Baer","sequence":"first","affiliation":[{"name":"Eidgen\u00f6ssiche Technische Hochschule (ETH), Experimental\r Ecology ETH-Zentrum NW, CH-8092 Zurich, Switzerland; and\r Keele University Chemistry Department, Keele,\r Staffordshire ST5 5BG, England"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.
