Flight Phenology of Spodoptera eridania (Stoll, 1781) (Lepidoptera: Noctuidae) in Its Native Range: A Baseline for Managing an Emerging Invasive Pest

Insects
Spodoptera eridania (Stoll, 1781) (Lepidoptera: Noctuidae) is an important pest with a broad host range and growing relevance due to its high dispersal capacity, recent invasions into Africa and Asia, and documented resistance to biological insecticides.

Flight Load Assessment for Light Aircraft Landing Trajectories in Windy Atmosphere and Near Wind Farms

Aerospace, 2018
This work focuses on the wake encounter problem occurring when a light, or very light, aircraft flies through or nearby a wind turbine wake. The dependency of the aircraft normal load factor on the distance from the turbine rotor in various flight and ...

Evaluating Field-Collected Populations of Cotesia flavipes (Hymenoptera: Braconidae): Enhancing Biological Traits and Flight Activity for Improved Laboratory Mass Rearing

Insects
Due to the biofactories’ concern for the quality of the parasitoid Cotesia flavipes (Hymenoptera: Braconidae), a common practice is to introduce a population collected from the field into the laboratory mass rearing, even without prior information about ...

Learning to fly: integrating spatial ecology with unmanned aerial vehicle surveys

Ecosphere, 2018
Despite the increasing importance of new survey tools such as unmanned aerial vehicles (UAVs), the implications of how their spatial deployment may interact with species detection errors have not yet been assessed.

Quantifying dispersal of a non-aggressive saprophytic bark beetle.

PLoS ONE, 2017
Long distance dispersal to locate suitable breeding sites is recognized as a key trait influencing the population dynamics and distribution of bark beetles and other saprophytic insects. While dispersal behavior has been studied for a range of aggressive

Characteristics and drivers of high-altitude ladybird flight: insights from vertical-looking entomological radar.

PLoS ONE, 2013
Understanding the characteristics and drivers of dispersal is crucial for predicting population dynamics, particularly in range-shifting species. Studying long-distance dispersal in insects is challenging, but recent advances in entomological radar offer

The catch of tortricid moths to pheromone traps in apple orchards. Part I. Dynamics of moths flight

Annales Horticulturae, 2015
The studies were conducted in three apple orchards in the Lublin province in the years 1999–2001. Their purpose was to establish the flight dynamics of three species of leaf tortricids (Spilonota ocellana, Pandemis cerasana, Archips podana) on the basis ...
