“…Thrips feed by puncturing plant cells and extracting the cellular fluid (Hunter & Ullman 1989), which results in plant cell death. Because of their thigmotactic behavior and preference of thrips for inhabiting concealed spaces on plants (Lewis 1973), feeding is concentrated near the base of emerging leaves.…”

“…In addition, western flower thrips is highly polyphagous infesting a wide range of about 200 wild and cultivated host species (Mantel and van de Vrie 1988). Thrips have piercing-sucking mouthparts, which enable them to feed on different types of plant cells (Hunter and Ullman 1989). Feeding on actively growing tissue leads to distortion, reduction in plant growth, and eventually yields loss, while feeding on expanded tissue results in the characteristic silver leaf scars, which affect product appearance and reduce market quality (de Jager et al 1995a).…”

NMR Metabolomics of Thrips (Frankliniella occidentalis) Resistance in Senecio Hybrids

Western flower thrips (Frankliniella occidentalis) has become a key insect pest of agricultural and horticultural crops worldwide. Little is known about host plant resistance to thrips. In this study, we investigated thrips resistance in F 2 hybrids of Senecio jacobaea and Senecio aquaticus. We identified thrips-resistant hybrids applying three different bioassays. Subsequently, we compared the metabolomic profiles of these hybrids applying nuclear magnetic resonance spectroscopy (NMR). The new developments of NMR facilitate a wide range coverage of the metabolome. This makes NMR especially suitable if there is no a priori knowledge of the compounds related to herbivore resistance and allows a holistic approach analyzing different chemical compounds simultaneously. We show that the metabolomes of thrips-resistant and -susceptible hybrids differed considerably. Thrips-resistant hybrids contained higher amounts of the pyrrolizidine alkaloids (PA), jacobine, and jaconine, especially in younger leaves.Also, a flavanoid, kaempferol glucoside, accumulated in the resistant plants. Both PAs and kaempferol are known for their inhibitory effect on herbivores. In resistant and susceptible F 2 hybrids, young leaves showed less thrips damage than old leaves. Consistent with the optimal plant defense theory, young leaves contained increased levels of primary metabolites such as sucrose, raffinose, and stachyose, but also accumulated jacaranone as a secondary plant defense compound. Our results prove NMR as a promising tool to identify different metabolites involved in herbivore resistance. It constitutes a significant advance in the study of plant-insect relationships, providing key information on the implementation of herbivore resistance breeding strategies in plants.

“…Thrips have many traits that characterize them as successful invaders: polyphagy, small size, afÞnity for enclosed spaces, short generation time, and a combination of asexual and sexual reproduction that leads to a high reproductive potential (Morse and Hoddle 2006). Their piercing-sucking mouthparts (Hunter and Ullman 1989) allow them to feed on actively growing tissue leading to distortion, reduction in plant growth and eventually yield loss while feeding on expanded tissue results in the characteristic silver leaf scars, which affect the product appearance and reduce market quality (de Jager et al 1995a). Additionally, F. occidentalis is the primary vector of tospoviruses among which the tomato spotted wilt virus (TSWV) is the most economically signiÞcant (Maris et al 2003).…”

Variation in Genetics and Performance of Dutch Western Flower Thrips Populations

et al. 2012

Invasion of pests may result in local adaptation and the development of biotypes specialized in different hosts. In this study, we investigated western flower thrips, Frankliniella occidentalis (Pergande), an invasive pest in Europe. Thrips from different commercial glasshouse crops within the Dutch Westland and a lab culture kept on chrysanthemum were compared. Genetic barcoding was applied for the identification of potential western flower thrips cryptic species in the Netherlands revealing that all western flower thrips populations studied belonged to the "glasshouse" strain reported in California as the only existing species in the Netherlands. Feeding and reproduction parameters in leaf disc and whole plant bioassays were scored. We detected significant differences in thrips feeding among host plants and thrips origin. Host plants differed in average thrips damage while thrips from different origins caused similar amounts of damage across host plants. In contrast, reproductive success of thrips on all plant species depended strongly on thrips origin. The thrips lab culture maintained on chrysanthemum obtained the highest levels of reproduction on chrysanthemum. Differences among the other thrips populations were relatively small. Amplified fragment length polymorphisms analyses were used to study genetic differences between western flower thrips populations and confirmed that the lab culture population was also genetically the most different of all studied populations. The results of the amplified fragment length polymorphisms analyses together with the better reproductive performance of thrips on the host plant on which they were maintained demonstrate the evolution of a lab biotype specialized in a particular host. This finding has potential relevance for future crop control and breeding programs.
