2012 journal article

Population genetic structure and colony breeding system in dampwood termites (Zootermopsis angusticollis and Z. nevadensis nuttingi)

INSECTES SOCIAUX, 59(1), 127–137.

By: W. Booth n, C. Brent*, D. Calleri*, R. Rosengaus, J. Traniello & E. Vargo n

author keywords: Ancestral termites; Termopsidae; Isoptera; Gene flow; Breeding system; Microsatellites; COI
TL;DR: Investigation of patterns of genetic diversity and differentiation within the dampwood termite Zootermopsis angusticollis collected from three geographically distinct locations in California, USA found each site was found to represent unique populations with limited levels of gene flow.

2005 journal article

Dual mechanism of queen influence over sex ratio in the ant Pheidole pallidula

BEHAVIORAL ECOLOGY AND SOCIOBIOLOGY, 58(6), 527–533.

By: L. Menten*, D. Fournier *, C. Brent n, L. Passera*, E. Vargo n & S. Aron *

author keywords: conflicts; juvenile hormone; kin selection; microsatellites; primary sex ratio; social hymenoptera; split sex ratio
TL;DR: It is shown that queens regulate colony sex ratio in two complementary ways: by determining the proportion of female eggs laid and by hormonally biasing the development ofFemale eggs into either a worker or reproductive form. (via Semantic Scholar)

2005 journal article

Endocrine changes in maturing primary queens of Zootermopsis angusticollis

JOURNAL OF INSECT PHYSIOLOGY, 51(11), 1200–1209.

By: C. Brent*, C. Schal n  & E. Vargo n

Contributors: C. Brent*, C. Schal n  & E. Vargo n

author keywords: reproduction; isoptera; queen; juvenile hormone; ecdysteroids
MeSH headings : Animals; Corpora Allata / growth & development; Corpora Allata / metabolism; Corpora Allata / physiology; Ecdysteroids / blood; Endocrine System / growth & development; Endocrine System / metabolism; Endocrine System / physiology; Female; Hemolymph / metabolism; Isoptera / growth & development; Isoptera / metabolism; Isoptera / physiology; Juvenile Hormones / blood; Juvenile Hormones / metabolism; Male; Ovary / growth & development; Ovary / metabolism; Ovary / physiology; Sex Characteristics; Sexual Behavior, Animal
TL;DR: The hypothesis that JH plays a dual role in termite queens depending on their stage of development is supported; an elevated JH titer in immature alates may maintain reproductive inhibition, but an elevated Titer in mature queens may stimulate ovarian activity. (via Semantic Scholar)

2003 journal article

Changes in juvenile hormone biosynthetic rate and whole body content in maturing virgin queens of Solenopsis invicta

JOURNAL OF INSECT PHYSIOLOGY, 49(10), 967–974.

By: C. Brent n & E. Vargo n

author keywords: reproduction; formicidae; queen; juvenile hormone; primer pheromone
MeSH headings : Animals; Ants / growth & development; Ants / metabolism; Corpora Allata / physiology; Female; Oogenesis / physiology; Pheromones / physiology; Sesquiterpenes / metabolism; Sexual Maturation / physiology
TL;DR: The hypothesis that the pheromone released by functional queens inhibits reproduction in virgin alates by suppressing corpora allata activity and the production of JH is supported. (via Semantic Scholar)

2001 journal article

Influence of sex-specific stimuli on ovarian maturation in primary and secondary reproductives of the dampwood termite Zootermopsis angusticollis

PHYSIOLOGICAL ENTOMOLOGY, 26(3), 239–247.

By: C. Brent* & J. Traniello *

author keywords: fecundity; oocyte; ovary; reproduction; social insects; Zootermopsis
TL;DR: Results demonstrate that male‐specific stimuli affect only the reproductive development of primary females, and suggest that the degree to which primary and secondary females depend on mate assistance may have shaped their physiological responses to the presence of a reproductive male.
