“…and showed that they differ largely between species of this genus. Using Luckwill's classification, type VI trichomes can be distinguished that physically entrap tiny arthropods, such as aphids and spider mites, in their secretions (Gentile et al, 1969;Rasmy, 1985). Similar phenomena have been reported for other solanaceous plants ( Gibson, 1976;Rasmy, 1985 ).…”

“…(Cantelo et al, 1974;Snyder and Carter, 1984). Because correlations between trichome density and spider mite fecundity have frequently been reported (Stoner and Stringfellow, 1966;Gentile et al, 1969;Stoner et al, 1968;Snyder and Carter, 1985 ), the exudate may be an important factor in determining reproductive success of spider mites on tomato.…”

You will be contacted as soon as possible. Tomato varieties used at present for commercial production in Dutch glasshouses have a high density of glandular trichomes on the stem, but a very low density on the leaves, The two-spotted spider mite, Tetranychus urticae Koch, and the predatory mite, Phytoseiulus persimilis AthiasHenriot, usually disperse from leaf to leaf via the stem, thereby incurring high risks of entrapment (and death) in the exudate of the glandular trichomes. These risks have been quantified on the tomato cv. 'Turbo' and an accession of Lycopersicon peruvianum almost free of glandular trichomes. The possible consequences for biological control are discussed and new perspectives for predator release strategies and for plant breeding are considered.

Tomato wild relatives are important sources of resistance to many pests of cultivated tomato [Solanum lycopersicum L. (syn. Lycopersicon esculentum Mill.)]. Eleven wild tomato accessions previously identified at AVRDC-The World Vegetable Center as resistant to Bemisia tabaci were evaluated for resistance to the two-spotted spider mite [Tetranychus urticae (Koch.)] based on egg numbers using the leaf disc and Tanglefoot no-choice bioassays, and damage scores in choice bioassays. Highest resistance based on choice and no-choice bioassays was identified in AVRDC S. galapagense accessions VI057400, VI045262, VI037869 and VI037239, and S. cheesmaniae accession VI037240, all of which are new sources of T. urticae resistance. In addition, S. pimpinellifolium accession VI030462 exhibited resistance only in the no-choice bioassay based on egg numbers. Resistance to T. urticae based on the number of eggs from the no-choice bioassays was positively correlated with density of type IV glandular trichomes and negatively correlated with densities of type V trichomes. All resistant accessions accumulated high levels of total acylsugars, which were positively associated with type IV trichomes. There was a significant negative relationship between acylsugar content and T. urticae egg numbers from the no-choice bioassays. There was high correlation between the results from the leaf disc test and the Tanglefoot nochoice bioassay. These findings support the possible presence of broad-based insect and mite resistance in accessions closely related to cultivated tomato.

“…Resistance to 16 pest species has been reported in accessions of wild lines such as Lycopersicon hirsutum f. typicum and L. hirsutum f. glabratum (Dimock 1981;Dimock and Kennedy 1983;Kauffman 1987). Both physical (Gentile et al 1969) and chemical (Williams et al 1980) factors have been reported in these accessions where in the trichome mediated resistance playing a major role. Other physical and chemical factors associated with the leaf lamella were also reported earlier (Quiros et al 1977;Elliger et al 1981).…”

Exploitation of host plant resistance (HPR) against insect pests has gained greater importance in intensive agriculture since the days of Reginald H. Painter. In spite of the initial euphoria mentioning few success stories, currently it warrants for introspection and redesigning of research strategies in developing insect tolerant/resistant crop cultivars. Conventional tools of resistance breeding, though successful, have lost its legacy because of temporal, manpower, and cost considerations. The declined output in terms of research publications or pest resilient crop cultivars stands testimony to the dwindling number of entomologists and breeders concentrating on such conventional tools. Many of the novel molecular approaches such as marker aided selection, mapping QTL have gained much prominence and few successful outputs are being popularized. Though many preliminary laboratory reports on molecular techniques in HPR are widely surfacing, their field success is less validated. The success of pest resilient cultivars depends on various factors including preference by growers based on better yield and economic parameters and in turn preference by consumers based on organoleptic characters. The sustained use of genetically modified crops is still suspected and debated. Further, the consumerist enigma attached to its wider adoption needs to be rusticated through ostensible safety studies. Our two decade-long experience in exploiting the resistant traits in a huge germplasm of tomato has given a far insight into the trends that were followed earlier, failures faced in developing insect tolerant cultivars and the conceptual changes visualized for the future, which are highlighted in this chapter.
