Male sex pheromone components in the butterfly Heliconius
10 Sex specific pheromones are known to play an important role in butterfly courtship, and may 11 influence both individual reproductive success and reproductive isolation between species. 12 Extensive ecological, behavioural and genetic studies of Heliconius butterflies have made a 13 substantial contribution to our understanding of speciation. However, although long suspected 14 to play an im...
متن کاملFemale-induced increase of host-plant volatiles enhance specific attraction of aphid male Dysaphis plantaginea (Homoptera: Aphididae) to the sex pheromone.
All aphid species studied so far share the same sex pheromone components, nepetalactol and nepetalactone. Variation by different enantiomers and blends of the two components released by different aphid species are limited and can only partially explain species-specific attraction of males to females. While some host-plant odours are known to enhance specific attraction of aphid species, herbivo...
متن کاملMale sex pheromone components in Heliconius butterflies released by the androconia affect female choice
Sex-specific pheromones are known to play an important role in butterfly courtship, and may influence both individual reproductive success and reproductive isolation between species. Extensive ecological, behavioural and genetic studies of Heliconius butterflies have made a substantial contribution to our understanding of speciation. Male pheromones, although long suspected to play an important...
متن کاملResponse of Aphidius colemani to aphid sex pheromone varies depending on plant synergy and prior experience.
A critical stage in the success of a parasitoid is the ability to locate a host within its habitat. It is hypothesized that a series of olfactory cues may be involved in altering the parasitoid's movement patterns at this stage of foraging. This paper focuses specifically on host habitat location and host location and the olfactory stimuli necessary to mediate the transition between these stage...
متن کاملTranscriptome comparison of the sex pheromone glands from two sibling Helicoverpa species with opposite sex pheromone components
Differences in sex pheromone component can lead to reproductive isolation. The sibling noctuid species, Helicoverpa armigera and Helicoverpa assulta, share the same two sex pheromone components, Z9-16:Ald and Z11-16:Ald, but in opposite ratios, providing an typical example of such reproductive isolation. To investigate how the ratios of the pheromone components are differently regulated in the ...
