“…Pubescence traits can mediate various aspects of the plantÐ herbivore interaction, including herbivore attraction to the host plant (Southwood 1986), adult attachment and/or oviposition (Callahan 1957, Webster et al 1975, Roberts et al 1979, Robinson et al 1980, Gannon et al 1994, Haddad and Hicks 2000, Malakar and Tingey 2000, egg survival (Poos andSmith 1931, Schillinger andGallun 1968), insect growth (Lambert et al 1992, Malakar andTingey 2000), insect movement (Webster et al 1975, Eisner et al 1998, Zvereva et al 1998, insect survival (Gilbert 1971, Eisner et al 1998, Haddad and Hicks 2000, and pupal mass (Malakar and Tingey 2000). However, far from being a general defense, the effect of pubescence may be positive, negative, or nonexistent, depending on the particular herbivore species (Southwood 1986, Hare andElle 2002) and the leaf hair type (glandular or nonglandular), density, and length (Andres and Connor 2003).…”

Two cultivars of the bean, Phaseolus vulgaris L., differing in densities of hooked trichomes were examined for resistance to the potato leafhopper, Empoasca fabae. The major plant factor affecting leafhopper performance was the density of hooked trichomes. Leafhoppers were impaled by these epidermal appendages, leading to wounding and death. Nymphal survival on the cultivar, “California Light Red Kidney” (hooked trichome density: 2000/cm2) was significantly less than that on “Brasil 343” (hooked trichome density: 400/cm2). Hooked trichomes limit damage to beans by reducing the population density of the potato leafhopper ZUSAMMENFASSUNG HAKENHAARE UND RESISTENZ VON PHASEOLUS VULGARIS GEGEN EMPOASCA FABAE (HARRIS) Hakenhaare der Bohne, Phaseolus vulgaris L. schützen gegen Befall durch die Kartoffelzikade, Empoasca fabae (Harris). Zikadenlarven werden auf diesen Haaren aufgespiesst. Sie werden verwundet, bleiben hangen und sterben vorzeitig. Zwei Bohnensorten mit unterschiedlicher Dichte an Hakenhaaren wurden auf ihren Einfluss auf Eiablage und Entwicklungsbiologie eingezwingerter Zikaden gepruft. Eiablage, Entwicklung und Wachstum unterschieden sich auf beiden Sorten nicht. Dagegen war die Larvenmortalität, welche durch das Aufspiessen an Haaren verursacht wird, auf der resistenten Sorte “California Light Red Kidney” 4–10 mal grösser als auf der anfälligen Sorte “Brasil 343”, welche eine funfmal geringere Dichte an Hakenhaaren hat. Im Zeltversuch wurden Populationen von Imagines und von Larven auf der Sorte “California Light Red Kidney” um 66%, beziehungsweise 88% reduziert verglichen mit solchen auf “Brasil 343”. Das Wachstum zikadenbefallener und zikadenfreier Pflanzen beider Sorten wurde ebenfalls im Zeltversuch untersucht. Die Reduktion der Blattflache und des Trockengewichts von Blättern, Stengeln und Wurzeln war bei zikadenbefallenen “Brasil 343” signifikant grosser als bei der resistenten Sorte. Demgemäss schliessen wir, dass Hakenhaare für sich allein wirksam sind, den Zikadenschaden bei “California Light Red Kidney” zu reduzieren und zwar durch Begrenzung der Überlebensrate und der Endpopulation

“…The results of the present studies further reveal that oviposition preference of leafhopper is more strongly influenced by the thickness and length of leaf veins compared to pubescence character. It has been reported that the more hairy leaves of resistant cultivars of cotton, okra, castor, potato and egg plant are less preferred for feeding and oviposition by leafhoppers (P oos and S mith , 1931; P arnell et al., 1949; J ayaraj , 1968; B roersma et al., 1972; M offit and R eynolds , 1972; A garwal et al., 1978; S ingh and A garwal , 1988). However, we could not find any significant relationship between hairiness and leafhopper oviposition.…”

The oviposition preference of the cotton leafhopper, Amrasca biguttula biguttula (Ishida) was investigated in relation to leaf‐vein characteristics of 12 plant species, namely okra, cotton, castor, pigeonpea, cowpea, cluster bean, green gram, egg plant, sesame, country mallow, portia tree and shoe flower. Observations on the oviposition of the leafhopper under no‐choice conditions were recorded on three occasions during the peak period of leafhopper incidence in the field. On all three occasions the leafhopper rejected green gram, shoe flower and portia tree for egg‐laying, thereby indicating non‐acceptance of these plants for oviposition. For the remaining plants, the number of eggs per leaf differed significantly. Okra received the maximum number of eggs. The lateral veins of castor, cotton, cowpea, egg plant and country mallow leaves received more eggs in comparison with the main vein and subveins whereas in okra the subveins received the highest number of eggs followed by lateral and main veins. The leaves of cluster bean, pigeonpea and sesame were devoid of subveins. In cluster bean and sesame the lateral veins received more eggs than the main vein but in pigeonpea the main vein received more eggs than the lateral veins. Correlations of trichome density and length with the number of eggs laid in different veins were non‐significant. All types of veins in okra leaves were thicker than the rest of the test plants, which might have stimulated more egg laying in okra. The thickness of each category of vein, namely main vein (r=0.60), lateral veins (r=0.65) and subveins (r=0.56) was found to be positively correlated with the number of eggs laid. The length of the main and lateral veins were also found to be positively and significantly related to the number of eggs laid. It can be concluded from the present investigations that leaf‐vein thickness and length are crucial factors in influencing the oviposition behaviour of the cotton leafhopper.
