Accelerated and synchronized oviposition induced by flight of young females may intensify larval outbreaks of the rice leaf roller. [PDF]

open access: yesPLoS ONE, 2015
Physiological management of migration-reproduction trade-offs in energy allocation often includes a package of adaptions referred to as the oogenesis-flight syndrome.

Model-Based Tracking of Fruit Flies in Free Flight

open access: yesInsects, 2022
Insect flight is a complex interdisciplinary phenomenon. Understanding its multiple aspects, such as flight control, sensory integration, physiology and genetics, often requires the analysis of large amounts of free flight kinematic data. Yet, one of the

Experimental investigation of some aspects of insect-like flapping flight aerodynamics for application to micro air vehicles [PDF]

open access: yes, 2009
Insect-like flapping flight offers a power-efficient and highly manoeuvrable basis for micro air vehicles for indoor applications. Some aspects of the aerodynamics associated with the sweeping phase of insect wing kinematics are examined by making ...

RoboFly: An Insect-Sized Robot With Simplified Fabrication That Is Capable of Flight, Ground, and Water Surface Locomotion [PDF]

open access: yesIEEE Transactions on robotics, 2020
Insect-sized ($\sim$100 mg) aerial robots have advantages over larger robots because of their small size, low weight, and low materials cost. Previous iterations have demonstrated controlled flight but were difficult to fabricate because they consisted ...

Effect of asymmetry in the restoring force of the "click" mechanism in insect flight [PDF]

open access: yes, 2016
The aim of this paper is to examine the effect of asymmetry in the force-deflection characteristics of an insect flight mechanism on its nonlinear dynamics.

Vortex trapping recaptures energy in flying fruit flies

open access: yesScientific Reports, 2021
Flapping flight is one of the most costly forms of locomotion in animals. To limit energetic expenditures, flying insects thus developed multiple strategies.

Biologically Inspired Feedback Design for Drosophila Flight [PDF]

open access: yes, 2007
We use a biologically motivated model of the Drosophila's flight mechanics and sensor processing to design a feedback control scheme to regulate forward flight.

Three-dimensional vortex structure in a wake of a free-flight butterfly

open access: yesNihon Kikai Gakkai ronbunshu, 2016
A number of studies on not only the mechanism of insect flight but also the flow field around insect wings have been performed. Especially, a number of recent studies have examined the flow field around insect wings using experimental and numerical ...

The bat–bird–bug battle: daily flight activity of insects and their predators over a rice field revealed by high-resolution Scheimpflug Lidar [PDF]

open access: yesRoyal Society Open Science, 2018
We present the results of, to our knowledge, the first Lidar study applied to continuous and simultaneous monitoring of aerial insects, bats and birds. It illustrates how common patterns of flight activity, e.g. insect swarming around twilight, depend on

So near and yet so far: Harmonic radar reveals reduced homing ability of nosema infected honeybees [PDF]

open access: yes, 2014
Pathogens may gain a fitness advantage through manipulation of the behaviour of their hosts. Likewise, host behavioural changes can be a defence mechanism, counteracting the impact of pathogens on host fitness.
