Trichomes occur in a multitude of forms and sizes. Although they have been used widely for taxonomic purposes, their adaptive significance has been all but ignored by the evolutionist and ecologist. It is clear that trichomes play a role in plant defense, especially with regard to phytophagous insects. In numerous species there is a negative correlation between trichome density and insect feeding and oviposition responses, and the nutrition of larvae. Specialized hooked trichomes may impale… 

Mechanisms of Trichomes and Terpene Compounds in Indigenous and Commercial Thai Rice Varieties against Brown Planthopper

Simple Summary Herbivorous insects and their host plants have a long history of co-evolution. Plants produce specialized morphological structures known as trichomes, which may be involved in the

Efficiency of Trichome-Based Plant Defense in Phaseolus vulgaris Depends on Insect Behavior, Plant Ontogeny, and Structure

TLDR
The process by which leafminer flies are entrapped by surface trichomes of the host plant is revealed and the capture efficiency is evaluated to contribute to the understanding of physical defenses against herbivores.

Trichomes that secrete substances of a mixed nature in the vegetative and reproductive organs of some species of Moraceae

TLDR
The trichomes found in the inflorescence of D. cayapia may exert a function in pollen grain adhesion and probably act in the protection against herbivores, pathogens, desiccation and/ or UV radiation.

Morphological Classification of Trichomes Associated with Possible Biotic Stress Resistance in the Genus Capsicum

TLDR
This study attempts to charaterize the trichome morphologies in 5 species of using a Field Emission Scanning Electron Microscopy (FESEM) and could provide basic informations for understanding the structure and function of trichomes on the epidermal differentiation and association with biotic stress tolerance.

Trichomes of the seed fern Blanzyopteris praedentata: implications for plant–insect interactions in the Late Carboniferous

The fronds and compound tendrils of the Stephanian (Late Carboniferous) seed fern Blanzyopteris praedentata possess several types of trichomes, two of which may, based on their morphology, have

TLDR
After considering the biology and geography of the major Soviet insect pests of cultivated alfalfa, it was concluded that the most likely insects responsible for the localized evolution of pod glandularity are species of Tychius.

Glandular trichomes as an inflorescence defence mechanism against insect herbivores in Iberian columbines

TLDR
It is concluded that glandular trichomes are part of an adaptive response against phytophagous insect herbivory, and this result adds evidence to the differentiation of the Iberian columbines through habitat specialization.

Inheritance and distribution of trichome phenotypes in Datura wrightii

TLDR
It is hypothesize that feeding by herbivorous insects and/or water stress may play a role in maintaining this polymorphism in natural plant populations.

Stinging Trichomes in Apocynaceae and Their Evolution in Angiosperms

TLDR
The glandular trichomes in Fischeria and Matelea can indeed be classified as stinging, and Apocynaceae is the seventh family for which this type of trichome has been reported.

Toxicity of Trichome Exudates of Nicotiana and Petunia Species to Tobacco Hornworm Larvae

TLDR
Leaves of Nicotiana and Petunia species that are highly toxic to larvae of the tobacco horn worm, Manduca sexta (Johannson), possess trichomes with liquid or sticky exudates, which were removed by washing with ethyl alcohol or water plus a detergent to reduce the toxicity.

TLDR
An investigation of the effects of 20 secondary plant chemicals on the survival, development, and feeding behavior of a polyphagous insect, Melanoplus bivittatus, found that diets containing innocuous chemicals were sometimes discriminated against, whereas diets containing som...

Glandular hairs providing resistance to aphids in certain wild potato species

TLDR
The potential value of this source of resistance to aphids, if incorporated into the cultivated potato, is discussed, especially with reference to the advantages of its being combined with other forms of resistance and to its effectiveness against virus vectors.

TLDR
The relationship between butterflies and their food plants is investigated, the examination of patterns of interaction between two major groups of organisms with a close and evident ecological relationship, such as plants and herbivores.

Jassid resistance and hairiness of the cotton plant.

TLDR
The conclusion is reached that hairiness of the leaf confers resistance to Jassid and that degree of leaf hairiness, measured in an appropriate manner, is a thoroughly reliable guide to degree of resistance.

The injurious Effects of the Hooked Epidermal Hairs of French Beans ( Phaseolus vulgaris L.) on Aphis craccivora Koch

TLDR
On some varieties of beans the hairs are less dense than on others and on these varieties the action of the hairs in inhibiting predators may be more important than their effect on the Aphids.
