Potential Benefits

Associational resistance occurs when host plants experience reduced attack when in the presence of other plant species (Atsatt & O'Dowd 1976, Tahvanainen & Root 1972). The issue is most studied in agriculture and forestry because of the potential benefits to pest control (Andow 1991, Brown & Ewel 1987, Tahvanainen & Root 1972), but recent research indicates that associational resistance may be relatively common in natural systems as well (Hjältén et al. 1993, Karban 2007, Vehviläinen et al. 2007, Wise et al. 2009; but see Östergård & Ehrlén 2005, White & Whitham 2000), especially against specialist herbivores (Hambäck et al. 2000, 2003; Stenberg et al. 2007).

Generalist And Specialist Herbivores

Pyrrolizidine alkaloids (PAs), a typical kind of secondary metabolites in plants, have important roles on defense against herbivores and pathogens; however, specialist herbivores adapted to PAs can use them as cues for oviposition and feeding. Thus, in the native ranges, PA diversity and concentration in plants were selected by the balance between pressure from generalist and specialist herbivores. In introduced ranges, where the specialist herbivores are absent, the introduced plants could increase concentration and diversity of PAs. This predication is deduced from the Shift Defense Hypothesis (SDH). In this research, we investigated whether there were any differences between native and invasive Senecio vulgaris plants (from Europe and China, respectively) with regards to the PA composition and concentration. We grew the native and invasive S. vulgaris plants in an identical condition and harvested them when they started to bloom. Their roots and shoots were separately harvested and dried. PA composition and concentration from powder of the shoots and roots were detected by using liquid chromatography – tanderm mass spectrometry (LC-MS/MS). We identified 14 PAs which belongs to the structural group senecionine – like PAs. Most of them occurred in both the native and invasive S. vulgaris plants, except the usaramine N – oxide that was only found in the native ones. From the 14 PAs identified, only riddelliine N – oxide had significantly higher present frequency in the invasive plants than in the native plants. The invasive S. vulgaris plants had significantly lower concentration of 3 individual PAs (seneciphylline N – oxide, spartioidine and spartioidine N – oxide) than the native ones. These results demonstrated that PA diversity and concentration of some individual PAs tended to reduce in the invasive range of S. vulgaris. This is contrary to the predictions of the SDH that the invasive plants would produce more qualitative defense than the native ones, and it is probably an evidence that a little trade – off between defense and growth happened to the S. vulgaris in China.

Abstract. Herbivore damage can induce anti-herbivore traits in plants. However, there is little data regarding how these induced traits affect a plant's palatability (an important factor in determining the likelihood and magnitude of herbivore damage) across multiple generations post-induction, or whether the effect of transgenerational induction differs between generalist and specialist herbivores. Here we used palatability as a measure of the effects of transgenerational defensive induction in wild radish plants. We conducted a greenhouse experiment to determine whether generalist (slugs) and specialist (caterpillars of the white cabbage butterfly) herbivores' preference for wild radish differed depending on the number of previous generations that experienced herbivory. We found lowered palatability in plants with two or three inductions in their past in the case of generalist slugs, while palatability to a specialist herbivore was not affected by transgenerational induction. We conclude that the history of herbivory experienced by a plant's ancestors over multiple generations may play an important role in its ability to defend itself against generalist herbivores, but not against the specialists with whom they have co-evolved. Our findings suggest that the effects that multiple past inductions may have on palatability down the family line can be expected to have ecological and evolutionary implications.

Abstract Myoporum spp. (Lamiales: Scrophulariaceae) native to Australia and New Zealand have been introduced into North America and have been widely planted as shrubs and ground covers in the California urban landscape. The invasive thrips, Klambothrips myopori Mound and Morris, invaded California in 2005 and feed exclusively on Myoporum. However, some commercial cultivars have suffered extensive damage, whereas others have not. In field studies and laboratory feeding tests of six different potential host species or cultivars, Myoporum laetum and Myoporum ‘Pacificum’ were identified as most suitable host plants of K. myopori. In laboratory trials, K. myopori failed to complete development on M. ‘Clean n Green’ and M. ‘Putah Creek’. Of the six varieties of Myoporum tested, K. myopori damage was only observed on M. laetum and M. ‘Pacificum’. Although K. myopori can successfully colonize and reproduce on several varieties of Myoporum, they demonstrated a preference for M. laetum and M. ‘Pacificum’ in laboratory and field trials.
