The Lygaeidae (sensu lato) are a highly successful family of true bugs found worldwide, yet
many aspects of their ecology and evolution remain obscure or unknown. While a few …

Host race formation, the establishment of new populations using novel resources, is a major
hypothesized mechanism of ecological speciation, especially in plant‐feeding insects. The …

Root hemiparasitic plants act as keystone species influencing plant community composition
through their differential suppression of host species. Their own performance also strongly …

The environmental influences of mothers on offspring traits, or maternal effects, often arise
from dietary differences experienced by mothers. However, few studies have explored if and …

The development of a phytophagous insect depends on the nutritional characteristics of
plants on which it feeds. Offspring from different females, however, may vary in their ability to …

Trophic specialists are expected to possess adaptations that increase the efficiency of
handling preferred prey. Such adaptations may constrain the ability to utilise alternative …

Host specialization is considered a primary driver of the enormous diversity of herbivorous
insects. Trade-offs in host use are hypothesized to promote this specialization, but they have …

The adaptation to alternate host plants of introduced herbivorous insects can be vital to
agriculture due to the emergence of crop pests. Historically, it is assumed that there are …

Several characteristics of habitats of herbivores and their food-plant communities, such as
plant-species composition and plant quality, influence population genetics of both …

Adaptation to different host plants can lead to host-associated differentiation (HAD). The
mites Oligonychus perseae and Oligonychus punicae have a broad range of host plants …
