Sex specificity of dispersal behaviour and flight morphology varies among tree hollow beetle species

Movement Ecology, 2022
Background Flight performance and dispersal behaviour can differ between sexes, resulting in sex-biased dispersal. The primary sex ratio of populations may also explain dispersal bias between sexes, as this bias may evolve with the primary sex ratio to ...

Differences in the Aerobic Capacity of Flight Muscles between Butterfly Populations and Species with Dissimilar Flight Abilities

PLoS ONE, 2014
Habitat loss and climate change are rapidly converting natural habitats and thereby increasing the significance of dispersal capacity for vulnerable species. Flight is necessary for dispersal in many insects, and differences in dispersal capacity may reflect dissimilarities in flight muscle aerobic capacity.

Seasonal flight patterns of Ips typographus in southern Sweden and thermal sums required for emergence [PDF]

, 2014
1 The spruce bark beetle Ips typographus is the major tree-killing bark beetle in Eurasia. To increase knowledge about its seasonal flight patterns and also about the thermal sums required for emergence a field study was conducted in southern Sweden from

Likelihood of extreme early flight of Myzus persicae (Hemiptera: Aphididae) across the UK [PDF]

, 2022
Myzus persicae (Sulzer, Hemiptera: Aphididae) is a major global crop pest; it is the primary aphid vector for many damaging viruses and has developed resistance to most insecticides.

Cancer risks from cosmic radiation exposure in flight: A review

Frontiers in Public Health, 2022
Aircrew (consisting of flight attendants, pilots, or flight engineers/navigators) are exposed to cosmic ionizing radiation (CIR) at flight altitude, which originates from solar activity and galactic sources.

Flight activity promotes reproductive processes in the fall armyworm, Spodoptera frugiperda

Journal of Integrative Agriculture, 2021
The fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae), has invaded many countries in Africa and Asia since 2016, posing a major threat to world food security.

Flight Mill Experiments and Computer Simulations Indicate Islands Recruit More Capable Flyers of Moths

Frontiers in Ecology and Evolution, 2021
Understanding the traits related to species colonization and invasion, is a key question for both pest management and evolution. One of the key components is flight, which has been measured for a number of insect species through radar and tethered flight

Flight Muscle and Wing Mechanical Properties are Involved in Flightlessness of the Domestic Silkmoth, Bombyx mori

Insects, 2020
Flight loss has occurred in many winged insect taxa. The flightless silkmoth Bombyx mori, is domesticated from the wild silkmoth, Bombyx mandarina, which can fly.
