Insects are the most diverse animal group on the planet. Their success is reflected by the
diversity of habitats in which they live. However, these habitats have undergone great …

Nutrition is critical to immune defence and parasite resistance, which not only affects
individual organisms, but also has profound ecological and evolutionary consequences …

Tolerance and resistance are the two ways in which hosts can lessen the effects of infection.
Tolerance aims to minimize the fitness effects resulting from incumbent pathogen …

Highlights•Diet can impact host-parasite outcomes in insects but there are no clear
patterns.•Protein is beneficial in some insects, fats or carbohydrates are better in others.•Diet …

Insects are attacked by the same classes of pathogens that attack other animals (eg, viruses,
bacteria, fungi, and parasites)(Fuxa and Tanada, 1987). Pathogens are a major cause of …

Migration often is associated with movement away from areas with depleted nutrients or
other resources, and yet migration itself is energetically demanding. Migrating Mormon …

Diet and health are intimately linked and recent studies have found that caloric restriction
can affect immune function. However, when given a choice between diets that differ in their …

Ecological immunology examines the adaptive responses of animals to pathogens in
relation to other environmental factors and explores the consequences of trade-offs between …

A rapidly advancing area of ecological immunology concerns the effects of diet on animals'
immunological responses to parasites and pathogens. Here, we focus on diet-mediated …
