Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

open access: yesEcological Entomology, Volume 51, Issue 5, Page 912-925, October 2026.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Production of Transgenic Silkworm Using Anti-Serum Against Diapause Hormone in Diapause Strains of Silkworm, Bombyx mori

open access: yes
In general, the silkworm, Bombyx mori, has a diapause trait in its eggs. Therefore, transgenic silkworm can be produced by embryonic microinjection using eggs laid by a non-diapause strain in B. mori. In this study, we performed microinjection using eggs

Dosage-dependent regulation of embryonic diapause by sorbitol dehydrogenase in the silkworm, Bombyx mori.

open access: yesPLoS Genetics
Insects have evolved diapause to cope with harsh environmental conditions, during which their metabolism undergoes significant remodeling. The silkworm, Bombyx mori, enters diapause in the early embryonic stage, a process critically regulated by the ...

Diapause survival requires a temperature-sensitive preparatory period

open access: yesCurrent Research in Insect Science
Diapause is a form of internally-controlled dormancy that allows insects to avoid stressful conditions and periods of low food availability. Eastern spruce budworm (Choristoneura fumiferana Clemens), like many cold-adapted insects, enter diapause well in

What makes a fly enter diapause?

open access: yes, 2007
Diapause is a dormant state that insects may undergo as a response to changing environmental conditions. In flies, like many insects inhabiting temperate zones, diapause occurs generally during the winter months when ambient temperatures are cool and ...

Egg diapause in Psorophora columbiae (Dyar and Knab) : development of a predictive diapause induction model

open access: yes, 1984
Typescript (photocopy).Diapause induction responses for Psorophora columbiae were investigated in photoperiod- and temperatue-controlled growth chambers. The results of these studies demonstrated that egg diapause was induced by photoperiods perceived by

Effect of stress and diapause in two Calliphoridae species [PDF]

open access: yes, 2013
Cultures of two Dipteran flies (Calliphora vicina (R-D) and C. vomitoria (L.)) were established to answer questions in regards to responses to thermal and desiccation stress, effects of diapause and the mechanisms which underpin diapause.

Ecophysiological consequences of variability in diapause intensity [PDF]

open access: yes
application/pdfDiapause intensity (DI) is a physiological trait represented by the duration of diapause under given conditions of environment. In many species, it is highly variable, probably being controlled by multiple genes and tends to form a cline ...
