Roles of (Z)-3-hexenol in plant-insect interactions

Plant polyploidy and insect/plant interactions.

We used flow cytometry and extensive geographic surveys of herbivore attack to test whether repeated evolution of autotetraploidy in the perennial herb Heuchera grossulariifolia Rydb. (Saxifragaceae) has created evolutionary barriers to attack by the specialist moth herbivore Greya politella (Prodoxidae). We found that the moth has colonized tetraploid as well as diploid populations, has coloni...

Plant–insect Interactions and Pollution

Maternal Effects in Insect-Plant Interactions:

Maternal effects occur when the phenotype or environment of a mother affects the phenotype of her offspring via some mechanism other than the transmission of genes. The primary objective of this review is to use examples from my own research on the interaction between seed beetles and their host plants to illustrate how maternal effects influence ecological interactions in nature. I explain how...

On Mathematical Modelling of Plant-Insect Interactions

Plants and Insects are studied since decades, but, most of the time, separately. In Agronomy, plants are studied in order to improve crop yields while insects are studied in order to control their (negative or positive) impacts on crop yields. It is well known that plants and insects are always in interaction but, surprisingly, they are very few mathematical models of these interactions. For in...
