The functional morphology of insect adhesive devices and its implications for ecology

Orchard, Michael James

Abstract

The aim of this thesis is to gain a better understanding of the constraints that affect insect adhesion with an emphasis on biological constraints such as plant defences against insects and the influence of abiotic factors on insect foraging. In chapter one of this theses, a literature review on the mechanisms of insect adhesion, the influence of attachment capabilities on foraging behaviour, plant-insect interactions, and synthetic insect barriers is presented, focusing on hymenoptera and coccinellids as representatives of the two basic insect pad types. In the following chapters we test the four leading hypothesis regarding insect adhesion (Contamination, Fluid absorption, Surface roughness and the effect of Surface Energy), before investigating the role of mechano-sensing via insect antenna on substrate choice and finally probing the link between surface properties and locomotion and adhesion. Throughout this thesis I use species of Hymenoptera and Coccinellids as representative species of the two basic adhesive pad types.
