Expulsion of anal fluid from the upturned abdomen was demonstrated to serve a defensive function in the thrips Bagnalliella yuccae. An allomone in the anal exudate was identified as γ-decalactone, a fruity-smelling compound that repelled potential predators. Chemical defenses may contribute to the ability of thrips to maintain large aggregations. 

Chemical ecology of the Thysanoptera

The chemical ecology of the Thysanoptera is identified with a variety of natural products discharged in anal droplets during confrontations with adversaries that may function as repellents, contact irritants, or in some cases, fumigants.

A Novel Long-Chained Acetate in the Defensive Secretion of Thrips

Defensive secretions of adult and larval Suocerathrips linguis were found to contain a long-chained acetates, (11Z)-11,19-eicosadienyl acetate, that was not previously known to occur naturally.

Social behaviour in a thrips from Panama

It is argued that the patchy, but intergenerationally stable, food supply is the primary factor which has promoted the evolution of advanced social behaviours in this species as opposed to most other thrips.

Chemical defence in thrips

The presented paper deals with defensive secretion used by Suocerathrips linguis, which contains esters of acetic acid and long chained saturated and unsaturated alcohols as main components and has a very high boiling point.

Semiochemicals of rose aphid, black citrus aphid (Hemiptera: Aphididae) and greenhouse thrips (Thysanoptera: Thripidae)

Two new species of aphid have been identified in Scotland: Toxoptera citricida Kirkaldy or black citrus aphid and Heliothrips haemorrhoidalis Bouche or greenhouse thrips.

Chemical composition of anal droplets of the eusocial gall-inducing thrips Kladothrips intermedius

Analysis of anal droplets of eusocial Acacia gall-inducing thrips Kladothrips intermedius and other thysanopteran species indicates that sensilla basiconica are not strongly sensitive to these droplet compounds.

Pollen-feeding in thrips (Insecta: Thysanoptera)

Eight species of thrips in three families fed readily on individual grains of pollen, but left the pollen wall, and pollen-feeding appears to be widespread among flower thrips.

An Unexpected Mixture of Substances in the Defensive Secretions of the Tubuliferan Thrips, Callococcithrips fuscipennis (Moulton)

Thysanoptera live in the sticky wax masses of adult females of the felt scale insect Callococcus acaciae and feeds on Kunzea shrubs (Myrtales: Myrtaceae).
