  • adult
  • In order to understand how linalool production may relate to H. armigera fitness, we compare adult oviposition and larval survival on transgenic Nicotiana tabacum (tobacco) with increased ( S )-linalool in vegetative and floral tissues with that on non-transformed controls. (biologists.org)
  • specificity
  • As applied to oviposition behavior of the butterfly Euphydryas editha , the rank order of preference is the order in which plants become acceptable as the insect searches, while specificity is quantified in terms of the rate at which searching insects become less discriminating. (springer.com)
  • The North American D. punctatus and D. valens , which are not sympatric with R. grandis but have a similar ecology as D. micans , could also elicit predator oviposition, which would suggest that specificity in this predator-prey system is constrained by geography. (springer.com)
  • preference
  • 3.Despite a strong preference for fermented substrates, moderate attraction to and oviposition on unfermented fruit might be adaptive in view of the fly's capacity to vector yeast. (lu.se)
  • sufficient
  • Marking fruit with this putative oviposition-deterring pheromone without associated egg laying was sufficient to induce the deterring effect, while oviposition alone without subsequent marking had no effect. (brillonline.com)
  • The length of activity of the oviposition-deterring pheromone described here should be sufficient to prevent multiple egg-laying into a host that cannot support more than one parasitoid larva, and thus reduce intraspecific competition. (brillonline.com)
  • effect
  • Chesson J (1984) Effect of notonectids (Hemiptera: Notonectidae) on mosquitoes (Diptera: Culicidae): predation or selective oviposition? (springer.com)
  • The oviposition-deterring effect was removed by rinsing fruit with a solution of 50% ethanol in water. (brillonline.com)
  • Spraying unmarked fruit with an ethanol-water rinsate of previously-marked berries induced the oviposition-deterring effect. (brillonline.com)
  • surface
  • We hypothesized that both the abundance of immature Anopheles and the recruitment of Anopheles (from oviposition or larval movement) is positively related to the amount of surface cover present. (springer.com)
  • To our knowledge, this is the first demonstration of a hymenopteran oviposition-deterring pheromone that is deposited externally on the surface of the fruit skin rather than on the surface of the parasitized larva. (brillonline.com)
  • results
  • Here we standardized conditions to perform the second blood feed efficiently, and our results show that oviposition is an essential factor for the success of multiple feeds. (hindawi.com)
  • role
  • On the other hand, application of the NO scavenger PTIO decreased the cycle frequency, indicating that NO must normally exert a continuous and dynamic role on the central pattern generator underlying the oviposition rhythm. (biologists.org)
