Frontiers in Physiology, 2019 Correct timing of diapause entry and exit is critical for a species' survival. While many aspects of insect diapause are well-studied, the mechanisms underlying diapause termination remain largely unknown.

Adult Emergence in Two Univoltine \u3ci\u3eCallosamia Promethea\u3c/i\u3e Populations: Preponderance of the Early Emerging Morph in the North and of the Late Emerging Morph in the South (Lepidoptera: Saturniidae) [PDF]
, 2017 Callosamia promethea is common on wild black cherry, Prunus serafina, at the University of Michigan Biological Station in northern lower Michigan. In this area the early emerging morph is preponderant, while to the south in northern Indiana, the late ...

Oikos, EarlyView.Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

Endocrine Mechanisms Regulating Post-Diapause Development in the Cabbage Armyworm, Mamestra brassicae. [PDF]
PLoS ONE, 2016 Diapause, a programmed developmental arrest at a specific stage, is common in insects and is regulated by hormones. It is well established that in pupal diapause, cessation of ecdysteroid secretion from the prothoracic glands (PGs) after pupal ecdysis ...

Diapause Dynamics And Host Plant Utilization of \u3ci\u3eColias Philodice, Colias Interior\u3c/i\u3e and Their Hybrids (Lepidoptera: Pieridae) [PDF]
, 2017 Abnormal diapause dynamics and, to a lesser extent, reduced efficiency of host utilization by hybrid larvae constitute potential post-zygotic barriers to gene flow between a multivoltine legume-feeder, Colias philodice (Lepidoptera: Pieridae) and a ...

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape
Pest Management Science, EarlyView.Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

PLoS ONE, 2015 The northernmost Harbin strain (N strain) of the Asian corn borer, Ostrinia furnacalis enters facultative diapause as fully grown larvae in response to short daylengths; whereas the southernmost Ledong strain (S strain) exhibits almost no diapause under ...

The chloride channel cystic fibrosis transmembrane conductance regulator (CFTR) controls cellular quiescence by hyperpolarizing the cell membrane during diapause in the crustacean Artemia [PDF]
, 2019 Cellular quiescence, a reversible state in which growth, proliferation, and other cellular activities are arrested, is important for self-renewal, differentiation, development, regeneration, and stress resistance.
