Effect of shelter on reproduction, growth and longevity of the German cockroach, Blattella germanica (Dictyoptera: Blattellidae)

European Journal of Entomology, 108(2), 205–210.

By: C. Gemeno*, G. Williams* & C. Schal n 

author keywords: Dictyoptera; Blattellidae; Blattela germanica; cockroach; shelter; fitness; population; aggregation; reproduction; growth; longevity
TL;DR: When shelters were available in arenas, nymphs developed faster, adults gained more body mass, and females produced more fertile oothecae than when arenas lacked shelters, and reducing or eliminating shelters should affect population growth of B. germanica in residential and industrial settings.

Impact of photoperiod on the sexual behavior of the black cutworm moth (Lepidoptera : Noctuidae)

ENVIRONMENTAL ENTOMOLOGY, 30(2), 189–195.

By: C. Gemeno n & K. Haynes*

author keywords: black cutworm moth; sex pheromone; migration; reproductive diapause; calling; periodicity
TL;DR: Although photoperiod length can influence calling, pheromone production, and male response, it has little effect on the age at which A. ipsilon reach sexual maturity, which cannot explain the delayed maturity observed in the field. (via Semantic Scholar)

Quantitative genetics of signal evolution: A comparison of the pheromonal signal in two populations of the cabbage looper, Trichoplusia ni

BEHAVIOR GENETICS, 31(2), 157–165.

By: C. Gemeno n, A. Moore*, R. Preziosi * & K. Haynes*

author keywords: communication; evolvability; genetic architecture; quantitative genetics; sex pheromone
MeSH headings : Animals; Evolution, Molecular; Female; Genetic Variation; Moths / genetics; Mutation / genetics; Phenotype; Quantitative Trait, Heritable; Sex Attractants / genetics; Species Specificity
TL;DR: The genetic architecture underlying the production of the sex pheromone of the cabbage looper moth, Trichoplusia ni, is examined to suggest that single gene mutations, once established, can be associated with further alterations in the genetic architecture and this has implications for the evolution of phersomone communication.
