Identification of chlorogenic acid as a resistance factor for thrips in chrysanthemum.
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 chrysanthemum (Dendranthema grandiflora). We identified thrips-resistant chrysanthemums applying bioassays. Subsequently, nuclear magnetic resonance (NMR)-base...
متن کاملReciprocal Hosts' Responses to Powdery Mildew Isolates Originating from Domesticated Wheats and Their Wild Progenitor
The biotroph wheat powdery mildew, Blumeria graminis (DC.) E.O. Speer, f. sp. tritici Em. Marchal (Bgt), has undergone long and dynamic co-evolution with its hosts. In the last 10,000 years, processes involved in plant evolution under domestication, altered host-population structure. Recently both virulence and genomic profiling separated Bgt into two groups based on their origin from domestic ...
متن کاملInduction of Jasmonic Acid-Associated Defenses by Thrips Alters Host Suitability for Conspecifics and Correlates with Increased Trichome Densities in Tomato
Plant defenses inducible by herbivorous arthropods can determine performance of subsequent feeding herbivores. We investigated how infestation of tomato (Solanum lycopersicum) plants with the Western flower thrips (Frankliniella occidentalis) alters host plant suitability and foraging decisions of their conspecifics. We explored the role of delayed-induced jasmonic acid (JA)-mediated plant defe...
متن کاملThrips Management in Arkansas Cotton
Thrips populations increase in the spring on early wild host plants and most likely on wheat. These hosts of thrips start to dry beginning in early May until midJune and thrips begin to migrate to more favorable food sources. Unfortunately, this is about the same time that cotton begins to grow. The large host acreage for thrips and their reproductive capability create a situation, in most year...
متن کاملReitz: Distribution of Thrips in Tomato 431 SEASONAL AND WITHIN PLANT DISTRIBUTION OF FRANKLINIELLA THRIPS (THYSANOPTERA: THRIPIDAE) IN NORTH FLORIDA TOMATOES
Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) , the western flower thrips, is the primary insect pest of tomatoes and other vegetable crops in northern Florida and the rest of the southeastern USA. However, it is not the only flower thrips present in the region nor is it always the most abundant species. To determine the seasonal and within plant distribution of these various ...
