The weather and mass flights of Thysanoptera

T. Lewis

TLDR
Mass flights of Thysanoptera occur when temperatures rise above the take-off threshold after migrants have accumulated on plants at temperatures too low for flight.
Abstract
SUMMARY Mass flights of Thysanoptera occur when temperatures rise above the take-off threshold after migrants have accumulated on plants at temperatures too low for flight. Most species fly in sunny, settled weather with slight convection and a maximum temperature of at least 20°C.

Invasion biology of thrips.

TL;DR: Factors facilitating invasion by thrips, damage caused by these insects, pre- and post-invasion management tactics, and challenges looming on the horizon posed by invasive Thysanoptera, which continually challenge the development of sustainable management practices are examined.

Clap and fling mechanism with interacting porous wings in tiny insect flight

TL;DR: The results of the study show that the porous nature of the wings contributes largely to drag reduction across the Re range explored, and was larger for some porosities when compared with solid wings.

An improved suction trap for insects

TL;DR: A suction trap for airborne insects, which automatically segregates the catch at pre‐set intervals and standardizes the samples for volume of air, has been previously described by Johnson and certain structural improvements were incorporated.

The changing numbers of aphis fabae scop., flying at crop level, in relation to current weather and to the population on the crop

TL;DR: The relation between total numbers caught at different wind-speeds shows that most of the migration occurred in winds when the aphids could have had no control over the general direction of flight, demolishing the current view that most migration takes place only in calm weather.

The effect of weather on emergence and take‐off of overwintering Limothrips cerealium Haliday (Thysanoptera)

T. Lewis
TL;DR: A temperature-dependent development period is necessary before thrips are ready to fly in spring, but in spring the temperature often fell below the take-off threshold before this, and sultry weather was not a necessity for spring flight.

The annual cycle of limothrips cerealium haliday (thysanoptera) and its distribution in a wheat field

TL;DR: The annual life cycle can be arbitrarily divided into six stages based primarily on the amount of flight activity: the females feed mainly on winter cereals and grasses in spring, many moving to later sown cereals in June and July, where most eggs are laid in the sheaths of the young leaves.

Biology and life history of limothrips cebeal1um haliday and aptinothrips rufus gmelin feeding on gramineae

TL;DR: It is suggested that there appears to be four races within the species, a sexual and a partheno-genetic race of each form, and an internal nematode parasite was found in Aptinothrips rufus.
