Photoperiod‐Regulated Thermal Tolerance of the Non‐Diapausing Insect Ceratitis capitata (Diptera: Tephritidae)

Entomologia Experimentalis et Applicata, EarlyView.
Developmental photoperiodic exposure (photoacclimation) from egg to adult emergence alters thermal tolerance in Ceratitis capitata. Flies reared under contrasting photoperiods (0:24, 8:16, 14:10, and 24:0 L:D) showed significant shifts in both CTmin and CTmax, whereas adult‐only photoacclimation affected CTmax but not CTmin.

New test reveals early diapause in pink bollworm

California Agriculture, 1993
Through basic research into genetic control of pink bollworm development, we devised a rapid immunological method of determining diapause in pink bollworm larvae - formerly a monthlong process which now requires only 24 hours. This new "ELISA" method has

Heat and Cold Shocks Decrease the Incidence of Diapause in Trichogramma telengai Larvae

Insects
Insect diapause and response to thermal stress are similar in the variety of manifestations. However, the influence of thermal shocks on the incidence of insect diapause has not been sufficiently studied. Our laboratory experiments showed that both cold (

Juvenile Hormone III but Not 20-Hydroxyecdysone Regulates the Embryonic Diapause of Aedes albopictus

Frontiers in Physiology, 2019
Diapause is an alternative developmental trajectory allowing insects to enter dormancy and persist through predictable periods of seasonally unfavorable conditions.

Integrating remote‐sensing and meteorological data to identify key drivers of the potential distribution of a grassland grasshopper

Ecological Entomology, EarlyView.
An ensemble model achieved excellent accuracy (AUC = 0.973) in predicting the potential distribution of O. decorus asiaticus. Climate (temperature & August precipitation) and vegetation type are the primary drivers defining the species' suitable habitats.

Heterokairic Genes and the Eco‐Evo‐Devo of Timing [PDF]

Evol Dev
Heterokairic genes as the bridge (Heterokairic Pathways?): Heterokairic genes are heterochronic regulators whose activity is modulated by environmental conditions. External cues (e.g., temperature, nutrition, oxygen, density: yellow box) are sensed (yellow arrows) and converted into endocrine and metabolic signals (purple box and arrow into fish's ...

Host plant use is driven by microclimate not nutritional quality in a grassland butterfly

Ecological Entomology, EarlyView.
Small Copper butterflies (Lycaena phlaeas) choose to lay eggs on host plants growing in warmer microclimates, despite lower nitrogen content. Bare ground created by European Moles increases host plant temperatures and weakens the negative relationship between nitrogen content and microclimatic warmth.
