MOLECULAR ECOLOGY, 13(2), 431–441.

By: C. Deheer n & E. Vargo n

author keywords: breeding system; colony fusion; colony genetic organization; Isoptera; microsatellites; territoriality
MeSH headings : Animals; Feeding Behavior / physiology; Gene Frequency; Genetics, Population; Hierarchy, Social; Isoptera / genetics; Microsatellite Repeats / genetics; North Carolina; Population Dynamics
TL;DR: It is demonstrated here that subterranean termite colonies with a similarly complex genetic composition can form under natural conditions via the fusion of whole colonies through repeated sampling from individual colonies over time and space. (via Semantic Scholar)

Polymorphic microsatellite loci in the European subterranean termite, Reticulitermes santonensis Feytaud

MOLECULAR ECOLOGY NOTES, 4(1), 127–129.

By: S. Dronnet*, A. Bagneres*, T. Juba n & E. Vargo n

author keywords: dinucleotide repeats; microsatellites; R.flavipes; Reticulitermes santonensis; tetranucleotide; repeats; trinucleotide repeats
TL;DR: The identification and characterization of two dinucleotide, two trinucleotide and eight tetranucleotide microsatellite DNA loci isolated from the European subterranean termite Reticulitermes santonensis indicate higher levels of inbreeding in these colonies due to the presence of numerous inbred replacement reproductives.

The diminutive supercolony: the Argentine ants of the southeastern United States

MOLECULAR ECOLOGY, 13(8), 2235–2242.

By: G. Buczkowski n, E. Vargo n & J. Silverman n

author keywords: Argentine ant; introduced species; invasive ants; microsatellites; nestmate recognition; unicoloniality
MeSH headings : Aggression / physiology; Animals; Ants / genetics; Ants / physiology; California; Demography; Gene Frequency; Genetic Variation; Genetics, Population; Geography; Microsatellite Repeats / genetics; Population Dynamics; Southeastern United States; Temperature
TL;DR: The results show that the southeastern L. humile population has high genotypic variability and strong intercolony aggression relative to the California population, suggesting that distinctly different colonization patterns for California and the Southeast may be responsible for the striking disparity in the genetic diversity of introduced populations.

Queen control of sex ratio in fire ants

SCIENCE, 293(5533), 1308–1310.

MeSH headings : Animals; Ants / genetics; Ants / physiology; Behavior, Animal; Female; Male; Models, Biological; Oviposition; Ovum / physiology; Reproduction; Sex Determination Processes; Sex Ratio; Social Behavior; Zygote / physiology
TL;DR: It is suggested that queens can force workers to raise male sexuals by limiting the number of female brood and help to explain why sex investment ratios lie between the queen and worker equilibria in this and many other ant species. (via Semantic Scholar)

Multiple glandular origins of queen pheromones in the fire ant Solenopsis invicta

JOURNAL OF INSECT PHYSIOLOGY, 46(8), 1151–1159.

By: E. Vargo* & C. Hulsey*

author keywords: communication; poison gland; postpharyngeal gland; mandibular gland; dealation; queen recognition pheromone
TL;DR: It is found that virgin queens whose poison sacs were removed before they began producing queen pheromone initiated production of a primer peromone that inhibits winged virgin queens from dealating, indicating that this pheromonal effect also has an additional but as yet undetermined source.
