Behavioral Response of Argiope trifasciata to Recent Foraging Gain: A Manipulative Study

摘要: Abstract This study investigates how recent foraging gain affects the web-building behavior of garden spider, Argiope trifasciata, especially stabilimentum-building. Adult female spiders in field and cages were randomly assigned to two groups, fed unfed. Spiders group received three grasshoppers each day; unfed no prey. The experiment was terminated after A. trifasciata had built four consecutive webs; number days required by spider recorded. During I recorded silk length, catching area, mesh size stabilimentum area web spun test spiders. Continuously fed, caged decreased output size, increased interval between successive bouts. Unfed, maintained shortened Although exhibited same trend, change...
