Periodic and Chaotic Flapping of Insectile Wings

open access: yes, 2015
Insects use flight muscles attached at the base of the wings to produce impressive wing flapping frequencies. The maximum power output of these flight muscles is insufficient to maintain such wing oscillations unless there is good elastic storage of ...

Wing Design in Flies: Properties and Aerodynamic Function

open access: yesInsects, 2020
The shape and function of insect wings tremendously vary between insect species. This review is engaged in how wing design determines the aerodynamic mechanisms with which wings produce an air momentum for body weight support and flight control.

INSECT FLIGHT TAKES OFF [PDF]

open access: yesJournal of Experimental Biology, 2004
This 1951 JEB classic paper, written at the dawn of the Golden Age of biology by Viking physiologists August Krogh and Torkel Weis-Fogh, was a collaboration between two men at opposite ends of their careers ([Krogh and Weis-Fogh, 1951][1]).

Odorant binding proteins promote flight activity in the migratory insect, Helicoverpa armigera

open access: yesMolecular Ecology, 2020
Migratory insects are capable of actively sustaining powered flight for several hours. This extraordinary phenomenon requires a highly efficient transport system to cope with the energetic demands placed on the flight muscles.

Radar studies of the vertical distribution of insects migrating over southern Britain: the influence of temperature inversions on nocturnal layer concentrations [PDF]

open access: yes, 2005
Insects migrating over two sites in southern UK (Malvern in Worcestershire, and Harpenden in Hertfordshire) have been monitored continuously with nutating vertical-looking radars (VLRs) equipped with powerful control and analysis software.

Flight-Fecundity Trade-offs: A Possible Mechanistic Link in Plant–Herbivore–Pollinator Systems

open access: yesFrontiers in Plant Science, 2022
Plant–herbivore and plant–pollinator interactions are both well-studied, but largely independent of each other. It has become increasingly recognized, however, that pollination and herbivory interact extensively in nature, with consequences for plant ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
