21. Semiochemical-mediated attraction and oviposition in pyralid moths
Sammanfattning : Moths use chemical signals emanating from food to find sites for oviposition and subsequent larval feeding. By identifying these odours, novel approaches to pest management can be developed, such as monitoring of females in pest populations. LÄS MER
22. Disruption of moth mating behaviour by olfactory and auditory cues
Sammanfattning : The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. LÄS MER
23. Speciation genetics of recently diverged species
Sammanfattning : Species differentiation can be a consequence of evolutionary forces including natural selection and random genetic drift. Patterns of genomic differentiation vary across the tree of life. This variation seems to be dependent on, for example, differences in genomic architecture and molecular mechanisms. LÄS MER
24. Male moth behaviour and perception in pheromone plumes
Sammanfattning : Behaviour of male moths and electrophysiological responses of male pheromone-specific olfactory receptor neurones were studied in two model species, the oriental fruit moth Grapholita molesta and the turnip moth Agrotis segetum. The studies were aimed at elucidating the relative importance of different mating disruption mechanisms. LÄS MER
25. Temperature variation in time and space, and its effects on insects
Sammanfattning : Nature is variable. Unfortunately, compressed representations of this variable world, like averages, are often lossy and insufficient for ecological purposes. This is particularly true for temperature variation, which organisms typically respond to in a nonlinear way. LÄS MER
