Effect of semiochemical exposure on flight propensity and flight capacity of Dendroctonus ponderosae in laboratory bioassays

Arthropod-Plant Interactions, 2021
During flight, insect herbivores respond to volatile organic compounds (VOCs) released by host and non-host plants or conspecifics. Dendroctonus ponderosae uses chemical cues including host and non-host VOCs, as well as aggregation pheromones to navigate through the environment and find a suitable reproductive host.

Electrophoretic variation at flight-related enzyme loci and its possible association with flight capacity inEpiphyas postvittana

Biochemical Genetics, 1991
Variations at three flight-related enzyme loci, delta-glycerophosphate dehydrogenase (delta-Gpdh), glucose-6-phosphate dehydrogenase (G6pd), and phosphoglucomutase (Pgm), of Epiphyas postvittana (Walker) moths were investigated using starch gel electrophoresis.

The Development of Flight Capacity in a Butterfly

Behaviour, 1956
Experiments have been made to determine and explain a possible increase in flight capacity of a butterfly during the first days after emergence. The height of phototropic flight reaction of males and females of Pieris napi of different age after emergence under constant and controlled experimental conditions has been tested. In one series (the T-series)

Airport Capacity Enhancement and Flight Predictability

Transportation Research Record: Journal of the Transportation Research Board, 2014
Justifications for enhancements to airport capacity are often framed in relation to flight delay reductions, but improvements to flight predictability also offer substantial benefits to the health of the aviation system. “Predictability” is defined in this paper as block time adherence and is measured as the difference between scheduled and actual ...

Size‐dependent flight capacity and propensity in a range‐expanding invasive insect

Insect Science, 2021
AbstractFor capital‐breeding insects, all resources available for adult metabolic needs are accumulated during larval feeding. Therefore, body size at adult eclosion represents the total energetic capacity of the individual. For female capital breeders, body size is strongly correlated with lifetime fecundity, while in males, body size, which ...
