Catalyzing Transitions to Sociality: Ecology Builds on Parental Care
- BiologyFront. Ecol. Evol.
There is evidence that social transitions to different types of societies are the result of long coevolutionary processes between environmental pressures and the care systems in a wide variety of taxa.
High density brood of Australian gall-inducing Acacia thrips aid in fungal control
- BiologyEvolutionary Ecology
This study investigates antifungal production in three Acacia thrips species, two gall-inducers: Kladothrips arotrum and Kladothsrips tepperi, and one kleptoparasitic thrips, Koptothria dyskritus, which suggests that effective defense against fungal pathogens is strongly associated with group size and colony maturity.
Flight muscle breakdown in the soldier caste of the gall-inducing thrips species, Kladothrips intermedius Bagnall
- BiologyInsectes Sociaux
A morphological assessment shows that a proportion of soldiers have body dimensions and wing lengths that fall within the range of dispersers, with males more so than females, however, longer wing length in soldiers did not correspond with a disperser like walking behaviour.
Biology of a new species of socially parasitic thrips (Thysanoptera: Phlaeothripidae) inside Dunatothrips nests, with evolutionary implications for inquilinism in thrips
Akainothrips francisi sp. nov. is shown to be an inquiline (i.e. it invades, and breeds within, domiciles of another species). Currently, its only known host is Dunatothrips aneurae, a subsocial…
Reproductive Caste Beats a Hasty Retreat
- BiologyJournal of Insect Behavior
Behavioral differences between castes of Kladothrips intermedius (Bagnall) when faced with the destruction of the gall are investigated, consistent with the view that soldiers are behaviorally distinct and committed to life in a gall while, dispersers seem to have somewhere to go.
Inbreeding ancestors: the role of sibmating in the social evolution of gall thrips.
- BiologyThe Journal of heredity
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.
Host-driven diversification of gall-inducing Acacia thrips and the aridification of Australia
- Biology, Environmental ScienceBMC Biology
Host-plant diversification and spatial heterogeneity of hosts have increased the potential for specialisation, resource partitioning, and unoccupied ecological niche availability for gall-thrips on Australian Acacia.
Australian Thysanoptera – biological diversity and a diversity of studies
- Environmental Science, Biology
Work in Australia has included the development of electronic methods of illustration, identification and information transfer about thrips, including the use of molecular methods for pest species recognition, and considerable advances have been made in Australia in the authors' knowledge of the relationships between thrips and plants.
Thysanoptera host-plant associations, with an account of species living on Tamarix, and a new species of Lissothrips (Phlaeothripidae).
Eight unrelated Thysanoptera species are known to be associated with the arid zone plant genus Tamarix [Tamaricaceae]. One new species, Lissothrips hemingi sp.n., is described from Iran based on…
