“…It has been suggested that correlation between constitutive and induced resistance can be investigated by experiments using a range of wild plants which exhibit low to high degrees of resistance (Lu et al 2004). Up to now, few studies have examined the correlation between the two types of resistance to common herbivores among closely related wild plant species, and trade-oVs between constitutive and induced resistance were detected in some cases (Lewinsohn et al 1991;Litvak and Monson 1998) but not in others (Zangerl and Berenbaum 1990;Thaler and Karban 1997).…”

Constitutive and induced plant resistance against herbivores occurs throughout the plant kingdom, but little is known about the evolutionary relationship between these two types of resistances. We examined the relationships between constitutive and induced resistance to the diamondback moth, Plutella xylostella, in 11 wild species of crucifers, and analyzed the changes in volatiles associated with their expression in two species. We used larvae of P. xylostella and jasmonic acid (JA) as elicitors of the induced response. The level of resistance was estimated as the relative number of eggs laid on the plants by P. xylostella. Substantial variation in constitutive resistance was observed among the 11 crucifer species. When the plants were damaged by larvae, a negative correlation was found between constitutive and induced resistance. However, a positive correlation was detected between constitutive and induced resistance when the plants were treated by JA. The shift in resistance was associated with changes in the emission of volatiles. These results strongly suggest that (1) a trade-off occurs between constitutive and induced resistance in wild crucifers, and that (2) such a trade-off can be observed by treating the plants with a natural, but not an artificial, elicitor.

“…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.…”

“…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). However, the effect of the JA-dependent plant defense on host suitability for herbivores is unknown.…”

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

ORCID IDs: 0000-0002-7563-0918 (H.A.); 0000-0003-0802-6208 (M.Y.H.).Here, we analyzed the interaction between Arabidopsis (Arabidopsis thaliana) and the American serpentine leafminer (Liriomyza trifolii), an important and intractable herbivore of many cultivated plants. We examined the role of the immunity-related plant hormone jasmonate (JA) in the plant response and resistance to leafminer feeding to determine whether JA affects host suitability for leafminers. The expression of marker genes for the JA-dependent plant defense was induced by leafminer feeding on Arabidopsis wild-type plants. Analyses of JA-insensitive coi1-1 mutants suggested the importance of JA in the plant response to leafminer feeding. The JA content of wild-type plants significantly increased after leafminer feeding. Moreover, coi1-1 mutants showed lower feeding resistance against leafminer attack than did wild-type plants. The number of feeding scars caused by inoculated adult leafminers in JA-insensitive coi1-1 mutants was higher than that in wild-type plants. In addition, adults of the following generation appeared only from coi1-1 mutants and not from wild-type plants, suggesting that the loss of the JA-dependent plant defense converted nonhost plants to accessible host plants. Interestingly, the glucosinolate-myrosinase defense system may play at most a minor role in this conversion, indicating that this major antiherbivore defense of Brassica species plants probably does not have a major function in plant resistance to leafminer. Application of JA to wild-type plants before leafminer feeding enhanced feeding resistance in Chinese cabbage (Brassica rapa), tomato (Solanum lycopersicum), and garland chrysanthemum (Chrysanthemum coronarium). Our results indicate that JA plays an important role in the plant response and resistance to leafminers and, in so doing, affects host plant suitability for leafminers.

“…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). However studies have also documented increased herbivore attraction to and oviposition on induced plants (Silva et al, 2012;Rojas, 1999;Landolt, 1993;Lu et al, 2004), highlighting the fact that the ecological function and significance of these induced plant responses remains to be proven (Hare, 2011;Takabayashi & Dicke, 1996). To date, studies on herbivore-induced plant responses have been mostly measured and interpreted from plant mediated effects caused by a single species of herbivore whereas, under natural conditions, plants are often infested and simultaneously fed upon by more than one herbivore species (Thompson, 1998;Strauss, 1991;Vos et al, 2001).…”

“…Further adding to the complexity, the current study shows that the responses of one host plant to herbivory had opposing effects on two congeneric insect herbivores. Other studies have shown that multiple host plants have opposing effects on a single insect herbivore species (Silva & Furlong, 2012;Lu et al, 2004). For instance, the diamondback moth (Plutella xylostella) laid more eggs on Jasmonic acid (JA) treated cabbage plants and fewer on JA treated Chinese cabbage, however Pieris rapae did not show such a differential response between JA treated and control cabbage and Chinese cabbage plants (Lu et al, 2004).…”

Invasion ecology of thrips in relation to seedling cotton

Cotton Gossypium hirsutum L. (Malvales: Malvaceae) crops are attacked by a variety of invertebrate pests that include the larvae of Lepidoptera, spider mites, aphids, locust, beetles and thrips. In Australia three species of thrips are regarded as cotton pests, Thrips tabaci Lindeman, Frankliniella schultzei Trybom and F. occidentalis Pergrande (Thysanoptera: Thripidae). Thrips damage can result in delayed development, the early production of fruiting bodies and increased susceptibility to disease. Despite this, the ecology of thrips in cotton producing regions is poorly understood; in particular host-plant relationships and the sources of thrips populations that invade cotton crops require further investigation. cotton seedling responses to herbivore damage were not instantaneous and that the period over which thrips behaviour modifying changes in the plants persisted was determined by both the type and extent of feeding damage. Both F. schultzei and F. occidentalis were attracted to plants iii damaged by two-spotted spider mites for much longer than they were to plants damaged by cotton bollworm larvae or bean spider mites. Similarly, F. schultzei was attracted to seedlings for much longer when higher densities of two-spotted spider mites damaged plants.The population sources of thrips that invade cotton crops and the abundance and species composition of thrips on cotton were investigated in field studies in the Namoi valley, New South Wales. Host plant utilization by thrips was quantified through a structured sampling program that estimated the presence and abundance of adult and larval thrips across various cultivated and uncultivated plant species. The floral and vegetative parts of different plant species were sampled regularly over two years, during which 65 different plant species were sampled. The seasonal composition of thrips on cotton changed from predominately T. tabaci on seedling cotton to F. schultzei and F. occidentalis on mature flowering cotton later in the season. High T. tabaci abundance on early season cotton was attributed to the high numbers of T. tabaci on the surrounding weed species, as hosts on which it was recorded were plentiful. In contrast, the patterns of F. occidentalis and F. schultzei abundance on cotton were not correlated with their abundances on the weeds but rather the emergence of cotton flowersThe genetic relationships of thrips on cotton relative to those on the other host plant species sampled was investigated by analysis of mitochondrial CO1 gene sequences. No evidence was found for cryptic species of T. tabaci or F. occidentalis in the populations sampled from weeds and cotton, indicating that they were not from different breeding populations. It is inferred that T. tabaci or F. occidentalis were moving from the weeds and other crops onto cotton. Weeds clearly play an important role in the population biology of thrips and thus they must be considered in in the potential pest management strategies. Results of this study indicate that it could be possible to pr...
