2004 journal article

Maternal investment affects offspring phenotypic plasticity in a viviparous cockroach

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 101(15), 5595–5597.

By: G. Holbrook n & C. Schal n 

Contributors: G. Holbrook n & C. Schal n 

MeSH headings : Animals; Birth Weight; Body Weight; Cockroaches / genetics; Cockroaches / physiology; Environment; Female; Larva / growth & development; Male; Molting / physiology; Ovariectomy / methods; Phenotype; Prenatal Nutritional Physiological Phenomena; Reproduction / physiology
topics (OpenAlex): Insect and Arachnid Ecology and Behavior; Plant and animal studies; Animal Behavior and Reproduction
TL;DR: It is reported here that the degree of maternal nutrient investment in developing embryos of the viviparous cockroach Diploptera punctata influences how quickly neonate males become adults and how large they are at adulthood. (via Semantic Scholar)

1998 journal article

Endocrine regulation of de novo aggregation pheromone biosynthesis in the pine engraver, Ips pini (Say) (Coleoptera : Scolytidae)

INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY, 28(9), 705–715.

By: J. Tillman*, G. Holbrook n, P. Dallara*, C. Schal n , D. Wood *, G. Blomquist *, S. Seybold*

author keywords: endocrine regulation; de novo pheromone biosynthesis; pine engraver; Ips pini; ipsdienol; 2-methyl-6-methylene-2,7-octadien-4-ol; juvenile hormone; cis-10,11-epoxy-3,7,11-trimethyl-E2,E6-dodecadienoic acid methyl ester; corpora allata; isoprenoids
topics (OpenAlex): Forest Insect Ecology and Management; Insect and Pesticide Research; Insect and Arachnid Ecology and Behavior
TL;DR: Data support a sequence of events leading to feeding-induced de novo pheromone biosynthesis in male I. pini and suggest that in this pathway JH III does not influence enzymatically-catalyzed reactions subsequent to the conversion of 3-hydroxy-3-methylglutaryl-coenzyme A to mevalonate.

1998 journal article

Juvenile hormone synthesis in relation to corpus allatum development in embryos of the viviparous cockroach Diploptera punctata

INVERTEBRATE REPRODUCTION & DEVELOPMENT, 33(1), 69–79.

By: G. Holbrook n, A. Chiang *, Y. Lee*, C. Lin* & C. Schal n 

author keywords: cockroach; viviparity; embryo; corpora allata; juvenile hormone; cell proliferation; ultrastructure
topics (OpenAlex): Insect and Arachnid Ecology and Behavior; Neurobiology and Insect Physiology Research; Insect Utilization and Effects
TL;DR: Development and biosynthetic activity of CA in embryos of a viviparous cockroach, Diploptera punctata, shows that between day 28 of embryogenesis and hatch rates of JH synthesis rose, plateaued and then fell. (via Semantic Scholar)

1998 journal article

Neural control of cell size in the corpora allata during the reproductive cycle of the cockroach Diploptera punctata (Dictyoptera : Blaberidae)

INVERTEBRATE REPRODUCTION & DEVELOPMENT, 33(1), 25–34.

By: A. Chiang *, G. Holbrook n, H. Cheng* & C. Schal n 

author keywords: cell size; cell growth; corpora allata; juvenile hormone; autophagy; atrophy; cockroach; Diploptera punctata
topics (OpenAlex): Neurobiology and Insect Physiology Research; Insect and Arachnid Ecology and Behavior; Animal Behavior and Reproduction
TL;DR: It is proposed that under normal physiological conditions the quantity of JH synthesized by a corpus allatum is determined largely by the total amount of cellular machinery available for JH production. (via Semantic Scholar)

1998 journal article

Social influences on nymphal development in the cockroach, Diploptera punctata

PHYSIOLOGICAL ENTOMOLOGY, 23(2), 121–130.

By: G. Holbrook n & C. Schal n 

author keywords: cockroach; group effect; isolation; nymphal development; growth rate; life history; beetle cockroach; Diploptera punctata
topics (OpenAlex): Insect and Arachnid Ecology and Behavior; Insects and Parasite Interactions; Plant and animal studies
TL;DR: Analysis of covariance showed that isolated males gained less weight than paired ones, not only in the first stadium, but in the second as well, and female nymphal development, unlike that of males, was not greatly affected by social factors. (via Semantic Scholar)

1997 journal article

Improved conditions for culture of biosynthetically active cockroach Corpora allata

Improved conditions for culture of biosynthetically active cockroach corpora allata. IN VITRO CELLULAR & DEVELOPMENTAL BIOLOGY-ANIMAL, 33(6), 452–458.

By: G. Holbrook n, A. Chiang * & C. Schal n 

MeSH headings : Animals; Cockroaches / cytology; Cockroaches / metabolism; Corpora Allata / cytology; Corpora Allata / drug effects; Corpora Allata / metabolism; Culture Media / pharmacology; Dose-Response Relationship, Drug; Female; Glucose / pharmacology; Juvenile Hormones / biosynthesis; Male; Organ Culture Techniques / methods; Trehalose / pharmacology
topics (OpenAlex): Insect and Arachnid Ecology and Behavior; Insect Utilization and Effects
TL;DR: It is shown that L-15B, a medium widely used in arthropod tissue culture, is superior to TC199 for both short- and long-term culture of cockroach corpora allata, and more appropriate to use L- 15B than TC 199 for short-term in vitro assays of juvenile hormone biosynthesis and for extended corporaAllata culture.

1997 journal article

Reproductive biology of the German cockroach, Blattella germanica: Juvenile hormone as a pleiotropic master regulator

ARCHIVES OF INSECT BIOCHEMISTRY AND PHYSIOLOGY, 35(4), 405–426.

By: C. Schal n , G. Holbrook n, J. Bachmann n & V. Sevala n

author keywords: cockroach; corpora allata; juvenile hormone; JH analog; food intake; ovary; Blattella germanica
topics (OpenAlex): Insects and Parasite Interactions; Insect and Arachnid Ecology and Behavior; Animal and Plant Science Education
TL;DR: Observations suggest that JH might regulate sexual receptivity in females indirectly through inhibition of signals associated with copulation even when titers of JH are permissive for receptivity. (via Semantic Scholar)
