Abstract. We present the first life history data for Oncothrips morrisi, a species in a clade of haplodiploid, Australian gall-inducing thrips that has a micropteran fighting morph in the first generation of the gall. Micropterans in other species in the clade have lower fecundity than their mother, and these species are considered eusocial. There is no such reproductive skew in O. morrisi, and the species is not eusocial by any definition. The volume of O. morrisi galls is between 4 and 20… 

Variation in propensity to defend by reproductive gall morphs in two species of gall-forming thrips

TLDR
Defensive behaviour of soldier morphs using in situ presentation of gall invading kleptoparasites calls into question the suitability of the term 'soldier' as applied to the gall-morph of thegall-forming thrips of Australia.

Social biology and sex ratios in the gall-inducing thrips, Oncothrips waterhousei and Oncothrips habrus

TLDR
A comparison of the proportion of the gall occupied by brood in O. waterhousei and another eusocial galling thrips, Kladothrips hamiltoni, suggests that local resource competition is higher in K. ham Miltoni, which might partly explain the lack of sex ratio bias in soldiers of the latter species.

The Evolutionary Ecology of Eusociality in Australian Gall Thrips: a ‘Model Clades’ Approach

TLDR
Analysis of the associations between genetic and ecological traits that resulted from the social-adaptive radiation of gall thrips with soldiers provides two main insights: first, fewer matings by foundresses, and less mating after dispersal, result in stronger local mate competition, higher relatedness (and a higher inbreeding coefficient) among soldier females, and a stronger female bias in dispersers.

Natural history and description of Oncothrips kinchega, a new species of gall-inducing thrips with soldiers (Thysanoptera: Phlaeothripidae)

A new species of gall-inducing thrips, Oncothrips kinchega sp. n., is described and its biology on the host plant Acacia carneorum was investigated. Our study showed that a single foundress initiates

Inbreeding ancestors: the role of sibmating in the social evolution of gall thrips.

TLDR
Microsatellite data used to estimate levels of inbreeding in four species of solitary gall thrips on Australian Acacia showed that the ancestral lineage that gave rise to soldiers was apparently highly inbred, and therefore, inbreeding could have played a role in the origin of sociality within this group.

The impact of kleptoparasitic invasions on the evolution of gall‐size in social and solitary Australian Acacia thrips

TLDR
Induction of a smaller gall by host founders will reduce the period of vulnerability to invasion (before soldiers become adults) for social thrips by allowing foundresses in these smaller galls to begin laying soldier‐destined eggs relatively sooner.

Proclivity and effectiveness in gall defence by soldiers in five species of gall-inducing thrips: benefits of morphological caste dimorphism in two species (Kladothrips intermedius and K. habrus)

TLDR
Results show that soldiers of Australian gall thrips are motivated and effective for gall defence, and data from naturally invaded galls demonstrate that soldiers in the field do kill Koptothrips, and vice versa.

The evolution of soldier reproduction in social thrips

TLDR
This is the first study to analyze the social-evolutionary trajectories of reproductive, behavioral, and morphological differentiation in the context of a species-level phylogeny and suggests that this difference in evolutionary routes to eusociality between taxa with soldiers andTaxa with foraging workers was driven by a weaker trade-off between helping and reproducing, and a greater ability of the helpers to withstand reproductive domination, in taxas with soldiers.

Life history of Kladothrips ellobus and Oncothrips rodwayi: insight into the origin and loss of soldiers in gall‐inducing thrips

TLDR
The life history of two solitary, gall‐inducing thrips and Oncothrips rodwayi was investigated, and data for solitary and eusocial species from previous studies were re‐analysed.

Reproductive division of labour coevolves with gall size in Australian thrips with soldiers

TLDR
It is argued that high levels of inbreeding by singly mated foundresses and incestuous mating by her soldier offspring are key to this evolutionary relationship because they make the relatedness of a female soldier to her daughters and sisters approximately equal.

Eusociality in Australian gall thrips

TLDR
The presence of eusociality is reported in a second haplodiploid insect taxon, the order Thysanoptera, which provides remarkable new opportunities for analysing the causes of the evolution of eUSociality.

Behavioural ecology of Australian gall thrips (Insecta, Thysanoptera)

TLDR
Data is presented on aspects of gall morphology, male and female morphology, behaviour, life cycles, and sex ratios for six gall-forming species, five species of inquilines (invaders that do not form galls), and one genus that uses secretions to glue phyllodes (modified petioles) together.

Phylogenetics of social behavior in Australian gall-forming thrips: evidence from mitochondrial DNA sequence, adult morphology and behavior, and gall morphology.

TLDR
The phylogeny implies that soldiers originatedonce or twice early in the history of this clade, that soldiers were lost once or twice, and that soldiers evolved from winged dispersers rather than from nonsoldier within-gall reproductive offspring of foundresses.

Ecology and evolution of galling thrips and their allies.

TLDR
Galling thrips, by virtue of their haplodiploid genetic system and their ecological relationships with plants and natural enemies, are useful for analyzing a wide range of ecological, evolutionary, and behavioral questions.

Philopatric reproduction, a prime mover in the evolution of termite sociality?

TLDR
It appears that philopatric reproduction, notwithstanding its importance in the biology of many extant termite species, is unlikely to have been a prime mover in the evolution of helping and of altruistic castes in termites.

COMPARATIVE ANALYSIS OF GALL MORPHOLOGY IN AUSTRALIAN GALL THRIPS: THE EVOLUTION OF EXTENDED PHENOTYPES

TLDR
The findings indicate that the main selective pressures driving the evolution of gall form in Australian gall thrips on Acacia involve inner surface area to volume relationships, which change in concert with foundress fecundity and the number of within‐gall generations.

Polymorphism and kleptoparasitism in thrips (Thysanoptera: Phlaeothripidae) from woody galls on Casuarina trees

TLDR
All four thrips species exhibit unusually high intrapopulation variation within all morphs, and this may be related to fluctuations in within-gall density and, for the kleptoparasites, deterioration of feeding conditions in older galls.

Split sex ratios and virginity in a gall‐inducing thrips

TLDR
These data provide the first empirical support for the constrained sex allocation model of Godfray in the gall‐inducing thrips, Kladothrips rugosus, which has been predicted in haplodiploid populations with high proportions of reproductive virgins.

High relatedness and inbreeding in two species of haplodiploid eusocial thrips (Insecta: Thysanoptera) revealed by microsatellite analysis

TLDR
It is implied that high relatedness and inbreeding are important for the evolution and form of social behavior in Australian gall-forming Thysanoptera.
