Function of plant odors in oviposition behaviors of the yellow peach moth Conogethes punctiferalis (Lepidoptera: Crambidae)

摘要: The effect of plant odors on the oviposition behaviors Conogethes punctiferalis (Guenee) female moths was explored in wind tunnel tests. complete behavioral process leading to egg-laying divided into five components: takeoff from release point, halfway flight, hovering close source, landing and substrates. Host accelerated takeoff, increased orientation stimulus source by before triggered egg-laying. Never did non-host turnip taproot accelerate even though components were all induced. Shortly sustained under indicated involvement different chemicals those for other components. Odors potato tubers leaves as an absolute never responses. detailed effects odor stimuli each component investigated transient manipulations a tunnel. A full supply host resulted longer time egg-laying, but showed no laying egg, whereas cessation at specific (e.g., takeoff) interrupted subsequent Even when removed just after catenated Suitable continuous olfactory stimulations are necessary enhancing host-finding efficiency terms both speed accuracy stimulating final site acceptance.
