Jasmonate-dependent plant defense restricts thrips performance and preference

Abstract

Background: The western flower thrips (Frankliniella occidentalis [Pergande]) is one of the most important insect herbivores of cultivated plants. However, no pesticide provides complete control of this species, and insecticide resistance has emerged around the world. We previously reported the important role of jasmonate (JA) in the plant's immediate response to thrips feeding by using an Arabidopsis leaf disc system. In this study, as the first step toward practical use of JA in thrips control, we analyzed the effect of JA-regulated Arabidopsis defense at the whole plant level on thrips behavior and life cycle at the population level over an extended period. We also studied the effectiveness of JA-regulated plant defense on thrips damage in Chinese cabbage (Brassica rapa subsp. pekinensis).

Disarming the Jasmonate-Dependent Plant Defense Makes Nonhost Arabidopsis Plants Accessible to the American Serpentine Leafminer

“…The JA-dependent plant defense is multifaceted; it involves increasing herbivore avoidance and shortening the herbivore's life cycle by decreasing egg production, hatching rates, etc. (Thaler et al, 2001;Lu et al, 2004;Rodriguez-Saona and Thaler, 2005;Abe et al, 2009). It is noteworthy that these facets may also play a part in host suitability for herbivores.…”

“…The chewing-type feeding by lepidopteran larvae (caterpillars) and the sucking-type feeding by aphids and whiteflies are the best understood feeding mechanisms from the viewpoint of the plant response to herbivore attacks (Rossi et al, 1998;Kahl et al, 2000;Reymond et al, 2000;Winz and Baldwin, 2001;Li et al, 2003;Nombela et al, 2003). Piercing and sucking-type feeding, which are characteristic of thrips and spider mites, respectively, have also been extensively analyzed (Parrella, 1995;Abe et al, 2008Abe et al, , 2009. The other important feeding manner with agricultural impact is mining-type feeding by leafminer larvae.…”

“…Reymond et al (2004) reported the importance of JA in plant resistance to cabbage butterfly (Pieris rapae), whereas Ellis et al (2002) reported that the JA-dependent plant defense is also involved in aphid resistance. JA-dependent plant defense also has a role in the response and resistance to thrips attack (Abe et al, 2008(Abe et al, , 2009. Interestingly, several reports indicate that application of JA can reduce the feeding, oviposition, and population growth of herbivores (Thaler et al, 2001;Lu et al, 2004;Rodriguez-Saona and Thaler, 2005;Abe et al, 2009).…”

Invasion ecology of thrips in relation to seedling cotton

“…These HIPVs can ultimately impact the behaviours of herbivorous arthropods (Agrawal, 1999;De Moraes et al, 2001;Karban, 2011). Many studies have examined the effects of induced plant responses on the behaviour of herbivores and their natural enemies and they have been shown to suppress herbivore feeding (Anderson & Agrell, 2005;Miyazaki et al, 2013), reduce herbivore attraction to and oviposition on induced plants (Bruinsma et al, 2007;Abe et al, 2009;Delphia et al, 2007;Bernasconi et al, 1998;De Moraes et al, 2001;Landolt, 1993) and attract herbivore natural enemies (Dicke et al, 1990;Turlings et al, 1990;Shiojiri et al, 2001;Vos et al, 2001;Dicke & Hilker, 2003). Consequently, these plant responses to herbivory have frequently been interpreted as plant defences against further herbivore attack (Karban & Myers, 1989;Karban & Baldwin, 1997;Agrawal & Sherriffs, 2001;Dicke & Baldwin, 2010).…”
