Insect overwintering in a changing climate.
Insects are highly successful animals inhabiting marine, freshwater and terrestrial habitats from the equator to the poles. As a group, insects have limited ability to regulate their body temperature and have thus required a range of strategies to support life in thermally stressful environments, including behavioural avoidance through migration and seasonal changes in cold tolerance. With resp...
متن کاملEicosanoid actions in insect immunity.
Insects express 3 lines of protection from infections and invasions. Their cuticles and peritrophic membranes are physical barriers. Infections and invasions are quickly recognized within insect bodies, and recognition launches 2 lines of innate immune reactions. Humoral reactions involve induced synthesis of antimicrobial peptides, the bacteriolytic enzyme lysozyme and activation of the prophe...
متن کاملPlant immunity to insect herbivores.
Herbivorous insects use diverse feeding strategies to obtain nutrients from their host plants. Rather than acting as passive victims in these interactions, plants respond to herbivory with the production of toxins and defensive proteins that target physiological processes in the insect. Herbivore-challenged plants also emit volatiles that attract insect predators and bolster resistance to futur...

We review recent advances in our understanding of the mechanisms of insect immune defence, but do so in a framework defined by the ecological and ADVANCES IN INSECT PHYSIOLOGY VOL. 32
متن کاملMaking connections in insect innate immunity.
I mmune response in the arthropod vector to virus infection is a critical determinant of transmission for arboviruses such as West Nile virus (WNV). The immune response modulates outcomes of infection such as viral load, incubation period required for transmission, and viral pathogenesis in the vector (1, 2). As insects appear to lack an adaptive immune response characteristic of vertebrates, t...
