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… Expand

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. Expand
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. Expand
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. Expand
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… Expand
Insect pests and the evolution of defensive glandular trichomes in alfalfa
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. Expand
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. Expand
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. Expand
Erinea formation on Quercus ilex leaves: anatomical, physiological and chemical responses of leaf trichomes against mite attack.
TLDR
The results showed that the structural and functional changes in leaf trichomes upon mite attack may be an effort of the leaf to compensate the damage caused by the pest. Expand
Trichomes in plant-herbivore interactions: the first line of defense of the wild tobacco Nicotiana attenuata against attacking insects
TLDR
It is demonstrated that not only omnivorous ants but most likely lizards also use M. sexta’s body and frass odor to locate their prey, and the identification of a trichome metabolite novel to the Solanaceae was led to. Expand
Stinging Trichomes in Apocynaceae and Their Evolution in Angiosperms
Stinging trichomes are rare in plants, occurring only in angiosperms, where they are reported for a few genera belonging to six families. Although there is no report of stinging trichomes in… Expand

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. Expand
THE INFLUENCE OF PLANT CHEMICALS ON THE FEEDING BEHAVIOR, DEVELOPMENT, AND SURVIVAL OF THE TWO-STRIPED GRASSHOPPER, MELANOPLUS BIVITTATUS (SAY), ACRIDIDAE: ORTHOPTERA
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... Expand
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. Expand
Resistance of Plants to Insects
TLDR
This chapter discusses the resistance of plants to insects, the ability of a certain variety to produce a larger yield of good quality than other varieties at the same initial level of infestation and under similar environmental conditions. Expand
BUTTERFLIES AND PLANTS: A STUDY IN COEVOLUTION
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. Expand
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. Expand
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. Expand
MORPHOLOGICAL AND CYTOLOGICAL VARIATION IN HELIANTHUS PETIOLARIS WITH NOTES ON RELATED SPECIES
TLDR
The morphological variation and geographical distribution of H. petiolaris, the cytogenetic analyses of hybrids within the species, and the results of hybridization with other annual species are considered. Expand
Effect of oak leaf tannins on larval growth of the winter moth Operophtera brumata
TLDR
The presence of increasing amounts of tannin in oak leaves as the season progresses may be one factor influencing selection for early larval feeding periods on oak leaves. Expand
Leaf Pubescence of Wheat as a Deterrent to the Cereal Leaf Beetle, Oulema melanopus
Ovipositional behavior, viability of eggs, and growth and survival of the young larvae of Oulema melanopus (L.) were adversely affected by the density of pubescence of wheat leaves. Gravid females… Expand
