Hooked Trichomes: A Physical Plant Barrier to a Major Agricultural Pest

  title={Hooked Trichomes: A Physical Plant Barrier to a Major Agricultural Pest},
  author={E. Pillemer and W. Tingey},
  pages={482 - 484}
Hooked epidermal appendages (trichomes) on leaves of field bean cultivars effectively capture nymph and adult leafhoppers. Frequency of capture and capture mortality are highly correlated with trichome density. Hooked trichomes inserted at angles less than 30� are ineffective in capture. 

Topics from this paper

Hooked trichomes limit damage to beans by reducing the population density of the potato leafhopper, leading to wounding and death of leafhoppers. Expand
Plant trichomes and the biomechanics of defense in various systems, with Solanaceae as a model
Plant trichomes are epidermal outgrowths of varying size and form. While the chemical defensive function of the secretory trichomes is well established, the biomechanical function of the non-glandu...
Interaction of bean leaf pubescence with rust urediniospore deposition and subsequent infection density
In the field where infection conditions are often less than optimum, leaf pubescence would partially explain the observed resistance, but the observed increase in total number of spores as well as similar infection densities on fully expanded leaves of glabrous and pubescent genotypes cannot be explained by the trichomes.

Diverging patterns of host use by phytophagous insects in relation to leaf pubescence in Arbutus xalapensis (Ericaceae)
Foliar pubescence in the mexican madrone (Arbutus xalapensis H.B.K.) is an extremely variable character and insect preference was strongly associated to mouthpart anatomy. Expand
Trichomes of Nama (Hydrophyllaceae) That Produce Insect-active Compunds
Morphological diversity of trichomes in Nama and their possible functional significance as a predator defense are discussed. Expand
Lima bean–lady beetle interactions: hooked trichomes affect survival of Stethorus punctillum larvae
The negative effect of Lima bean hooked trichomes on a predacious lady beetle that attacks the two-spotted spider mite is highlighted, indicating that survival rate increased as trichome density decreased. Expand
The effects of foliar pubescence and nutrient enrichment on arthropod communities of Metrosideros polymorpha (Myrtaceae)
Abstract.  1. Nutrient resource availability and host‐plant foliar pubescence both influence arthropod food webs, but multifactor studies are needed to understand their interdependence and relativeExpand
Differential mechanical defense : herbivory, evapotranspiration, and leaf-hairs
Correlative and experimental evidence indicate that patterns of herbivory observed in this plant, in which older, less pubescent leaves are more frequently attacked than are more pubescent young leaves, may be explained by differences in pubescence associated with leaf age. Expand
Adaptations of two specialist herbivores to movement on the hairy leaf surface of their host, Solanum guaraniticum Hassl (Solanaceae)
The hypothesis that the success on the use of densely haired hosts by two cassidine species is determined by differential morphology and behavior is examined, allowing these two Cassidinae larvae to efficiently move on the pubescent leaf surface of their host. 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, haveExpand


Butterfly-Plant Coevolution: Has Passiflora adenopoda Won the Selectional Race with Heliconiine Butterflies?
Hooklike trichomes of Passiflora adenopoda provide a specific, effectively absolute defense against heliconiine butterfly larvae, a major class of Passiflora herbivores. It is suggested that sinceExpand
Some effects of soybean pubescence on populations of the potato leafhopper.
Populations of Empoasca fabae (Harris) were compared on soybean varieties having different types and amounts of pubescence. The orientation of the hairs was more important in resistance to theExpand
The injurious Effects of the Hooked Epidermal Hairs of French Beans ( Phaseolus vulgaris L.) on Aphis craccivora Koch
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

It is clear that trichomes play a role in plant defense, especially with regard to phytophagous insects, and in numerous species there is a negative correlation between trichome density and insect feeding and oviposition responses, and the nutrition of larvae. Expand
