▪ Abstract Host plant quality is a key determinant of the fecundity of herbivorous insects.
Components of host plant quality (such as carbon, nitrogen, and defensive metabolites) …

▪ Abstract Inherited environmental effects are those components of the phenotype that are
derived from either parent, apart from nuclear genes. Inherited environmental effects arise …

The dazzling variation in plant chemistry is a primary mediator of trophic interactions,
including herbivory, predation, parasitism, and disease. At the same time, such interactions …

Knowledge of the relationship between body size and fitness is essential in many models of
parasitoid evolutionary ecology. One clear point emerging from previous studies is that the …

Maternal nutritional stress lowers the organic content of eggs and slows the initial growth of
larvae of sea urchins and bivalves. Also, larval nutritional stress changes the form and …

Parental information about the prevailing environmental condition may enable offspring to
adjust their phenotypes in accordance with future demands. 2. The state-of-the-art …

We used a novel approach to study the effects of egg size on offspring fitness components in
Drosophila melanogaster. Populations that differed genetically in egg size were crossed …

The tomato leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae), is a widespread
devastating pest reported to develop on economically important solanaceous crops. The …

While theoretical models of the evolution of parental care are based on the assumption of
underlying genetic variance, surprisingly few quantitative genetic studies of this life-history …

Egg size variation often has large effects on the fitness of progeny in insects. However, many
studies have been unable to detect an advantage of developing from large eggs, suggesting …
