2000 journal article

Effects of ovariectomy and mating on the activity of the corpora allata in adult female Blattella germanica (L.) (Dictyoptera : Blattellidae)

PHYSIOLOGICAL ENTOMOLOGY, 25(1), 27–34.

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

author keywords: Blattella germanica; colleterial glands; corpora allata; Juvenile Hormone; mating; ovariectomy; vitellogenesis
TL;DR: It is concluded that both the ovary and mating stimulate the synthesis of JH early in the reproductive cycle, but that neither is needed for the occurrence of a complete cycle ofJH synthesis. (via Semantic Scholar)

2000 journal article

Role of feeding in the reproductive 'group effect' in females of the German cockroach Blattella germanica (L.)

JOURNAL OF INSECT PHYSIOLOGY, 46(6), 941–949.

By: G. Holbrook n, E. Armstrong n, J. Bachmann n, B. Deasy n & C. Schal n 

author keywords: cockroach; reproduction; feeding; group effect; social facilitation
TL;DR: It is concluded that both group rearing and food intake accelerate oöcyte development by diminishing the brain's inhibition on the synthesis of juvenile hormone. (via Semantic Scholar)

1999 journal article

Food intake in Blattella germanica (L.) nymphs affects hydrocarbon synthesis and its allocation in adults between epicuticle and reproduction

ARCHIVES OF INSECT BIOCHEMISTRY AND PHYSIOLOGY, 41(4), 214–224.

By: H. Young n, J. Bachmann n & C. Schal n 

author keywords: hydrocarbons; feeding; starvation; synthesis; parental investment; German cockroach; Blattella germanica
TL;DR: Hydrocarbons appear to serve an important cross-stadial resource and the object of competition among several nymphal and adult tissues and trade-offs in allocations in food-limited insects. (via Semantic Scholar)

1999 journal article

Site of synthesis, tissue distribution, and lipophorin transport of hydrocarbons in Blattella germanica (L.) nymphs

JOURNAL OF INSECT PHYSIOLOGY, 45(4), 305–315.

By: H. Young n, J. Bachmann n, V. Sevala n & C. Schal n 

author keywords: Blattella germanica; hydrocarbons; hemolymph; cuticle; lipophorin; epidermis
TL;DR: It is concluded that in the last stadium HC is synthesized by abdominal oenocytes, loaded onto hemolymph lipophorin, and transported to fat body and both nymphal and imaginal cuticle, suggesting that the fat body serves as a storage site for HC during cuticle formation.

1997 journal article

Lipophorin: A hemolymph juvenile hormone binding protein in the German cockroach, Blattella germanica

INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY, 27(7), 663–670.

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

author keywords: Blattella germanica; lipophorin; juvenile hormone; binding protein; hemolymph; pyriproxyfen; fenoxycarb; pheromone; photoactivation
TL;DR: Competitive displacement studies with racemic JH III, JH I, cuticular hydrocarbon, contact sex pheromone, and the JH analogs pyriproxyfen, fenoxycarb, and hydroprene showed that only JHIII readily displaced [ 3 H](10 R )JH III from the binding site. (via Semantic Scholar)

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
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)
