“…For example, volatiles emitted by potato plants in responses to JA application enhanced the plant's attractiveness to female Colorado potato beetles (Landolt et al, 1999). In wild radish, responses induced by JA application increased feeding by some herbivores (Agrawal, 2000;Agrawal and Sherriffs, 2001). In addition, N. lugens female adults tended to prefer 10 mM JA-elicited plants to the buffer.…”

Exogenous Application of Jasmonic Acid Induces Volatile Emissions in Rice and Enhances Parasitism of Nilaparvata lugens Eggs by theParasitoid Anagrus nilaparvatae

Abstract-Jasmonate signaling pathway plays an important role in induced plant defense against herbivores and pathogens, including the emission of volatiles that serve as attractants for natural enemies of herbivores. We studied the volatiles emitted from rice plants that were wounded and treated with jasmonic acid (JA) and their effects on the host-searching behavior of the rice brown planthopper, Nilaparvata lugens (Stål), and its mymarid egg parasitoid Anagrus nilaparvatae Pang et Wang. Female adults of N. lugens significantly preferred to settle on JA-treated rice plants immediately after release. The parasitoid A. nilaparvatae showed a similar preference and was more attracted to the volatiles emitted from JA-treated rice plants than to volatiles from control plants. This was also evident from greenhouse and field experiments in which parasitism of N. lugens eggs by A. nilaparvatae on plants that were surrounded by JA-treated plants was more than twofold higher than on control plants. Analyses of volatiles collected from rice plants showed that JA treatment dramatically increased the release of volatiles, which included aliphatic aldehydes and alcohols, monoterpenes, sesquiterpenes, methyl salicylate, n-heptadecane, and several as yet unidentified compounds. These results confirm an involvement of the JA pathway in induced defense in rice plants and demonstrate that the egg parasitoid A. nilaparvatae exploits plant-provided cues to locate hosts.

“…More recent work has shown that the consequences of these responses include the suppression of further herbivore feeding (Anderson & Agrell, 2005;Miyazaki et al, 2013), reduced preference (i.e. oviposition or attraction) of certain herbivores for plants induced by herbivore feeding (Karban, 1989;Karban & Baldwin, 1997;Agrawal & Sherriffs, 2001) and the attraction of carnivorous natural enemies of herbivores (Figure 1.9) (Dicke et al, 1990;Turlings et al, 1990;Shiojiri et al, 2001;Vos et al, 2001;Dicke & Hilker, 2003). Ecologists have highlighted the potential role induced-plant responses play in regulating herbivore populations (Karban, 1993;Soler et al, 2009).…”

“…Herbivore-induced plant responses should not be viewed as only having a defensive role, this is in part due to the fact that herbivore feeding can also result in induced susceptibility to additional attack and may even have no effect (Agrawal, 2000;Agrawal & Sherriffs, 2001 (Dicke & van Loon, 2000). Accordingly, Colorado potato beetles were more attracted to herbivore damaged potato plants compared to undamaged plants (Landolt et al, 1999) even though the damage caused by Colorado potato beetles to potato plants stimulate the increased production of proteinase inhibitors that suppress Colorado potato beetle feeding (Green & Ryan, 1972).…”

“…All references cited are included in the thesis bibliography. (Karban & Myers, 1989;Johnson, 2011) and these induced responses are widely considered to constitute a form of defence (Karban & Baldwin, 1997;Agrawal & Sherriffs, 2001). The volatiles released by plants in response to insect herbivory alter the course of the insect-plant interaction (Underwood & Rausher, 2002;Ohgushi, 2008) and reduced rates of attraction of certain herbivores to damaged plants are often cited as evidence of a defensive role for these chemicals (Karban & Myers, 1989;Karban & Baldwin, 1997;Agrawal & Sherriffs, 2001).…”

“…In cotton plants (Gossypium hirsutum) herbivory can result in the suppression of further herbivore feeding (Miyazaki et al 2013;Anderson & Agrell, 2005;Kranthi et al, 2003;Bezemer et al, 2003;Alborn et al, 1996), reduced herbivore attraction and oviposition (Landolt, 1993;Karban & Carey, 1984;Karban, 1986;Agrawal & Klein, 2000) and the attraction of herbivore natural enemies (Ngumbi et al, 2009). Such responses have been widely interpreted as a form of defence against herbivore attack (Dicke & Baldwin, 2010;Karban & Myers, 1989;Karban & Baldwin, 1997;Agrawal & Sherriffs, 2001) but in many systems the ecological function and significance of the chemical changes measured in plants remains to be proven (Hare, 2011).…”

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...
