TLDR
Adaptive hypotheses proposed to explain sex differences in plasticity, including those that predict that plasticity will be lowest for traits under strong selection (adaptive canalization) or greatest for trait under strong directional selection (condition dependence), are explored.Abstract:
Males and females of nearly all animals differ in their body size, a phenomenon called sexual size dimorphism (SSD). The degree and direction of SSD vary considerably among taxa, including among populations within species. A considerable amount of this variation is due to sex differences in body size plasticity. We examine how variation in these sex differences is generated by exploring sex differences in plasticity in growth rate and development time and the physiological regulation of these differences (e.g., sex differences in regulation by the endocrine system). We explore adaptive hypotheses proposed to explain sex differences in plasticity, including those that predict that plasticity will be lowest for traits under strong selection (adaptive canalization) or greatest for traits under strong directional selection (condition dependence), but few studies have tested these hypotheses. Studies that combine proximate and ultimate mechanisms offer great promise for understanding variation in SSD and sex differences in body size plasticity in insects.read more

Insect responses to heat: physiological mechanisms, evolution and ecological implications in a warming world.
Daniel González-Tokman,Alex Córdoba-Aguilar,Wesley Dáttilo,Andrés Lira-Noriega,Rosa Ana Sánchez-Guillén,Fabricio Villalobos +5 more
TL;DR: This review shows that, apart from the stress response mediated by heat shock proteins, the physiological mechanisms of heat tolerance in insects remain poorly studied, and emphasizes the importance of incorporating physiological information for modelling species distributions and ecological interactions under global warming scenarios.

Evolution of Sexual Dimorphism in the Lepidoptera
TL;DR: The primary goal is to identify mechanisms that either facilitate or constrain the evolution of sexual dimorphism, rather than to resolve any perceived controversy between hypotheses that may not be mutually exclusive.

Plant products as fumigants for stored-product insect control [Erratum: 2008, v. 44, issue 3, p. 304.]
S. Rajendran,V. Sriranjini +1 more
TL;DR: In this article, a review of research studies on plant essential oils and their constituents as fumigants, i.e., compounds acting on target insects in the vapour or gaseous phase, against stored-product insects have been reviewed.
