“…Solanum carolinense is a clonal perennial weed native to the eastern United States and is invasive in parts of North America and Asia (Bassett and Munro , Miyazaki ). It primarily colonizes disturbed fields and roadsides (Miyazaki ) and hosts a large arthropod community, including L. juncta (Chrysomelidae) and Manduca sexta (Sphingidae) (Wise ). Clonal lines of S. carolinense were obtained from natural populations in north Florida and Georgia (Appendix : Table S1); before use in this study, they were propagated for 3 yr in the glasshouse.…”

Abstract. Many studies show that indirect interactions between insect herbivores via shared host plants are common and often mediated by plant-induced responses to damage. However, we lack some types of data that will be needed to model how plant-mediated interactions on individual plants contribute to the population dynamics of interacting herbivores. Specifically, there are few simultaneous characterizations of both the intra-and interspecific effects that are mediated by the host plant, as well as host plant constitutive resistance. Additionally, as herbivores are likely to move among plants that differ in quality, we must consider how this set of intra-and interspecific effects differs among plant genotypes-that is, how plantmediated effects genetically vary or covary. We examined how the set of intra-and interspecific indirect effects involving the insect folivores Leptinotarsa juncta and Manduca sexta varies across different genotypes of a shared host plant, Solanum carolinense. We damaged 12 plant genotypes using both herbivore species, then measured effects on the growth of both con-and heterospecifics, as well as constitutive resistance to each herbivore. We then tested for genetic variation and covariation in plant-mediated effects and constitutive resistance among plant genotypes. We found that on average, there were significant negative intraspecific plant-mediated effects on the growth rate of both herbivores, as well as asymmetric negative interspecific effects of M. sexta on L. juncta. Both intra-and interspecific effects varied across plant genotypes. For example, the interspecific effect of M. sexta on L. juncta ranged from significantly negative to significantly positive. Additionally, there were strong correlations among the individual effects mediated by S. carolinense, particularly between constitutive resistance and both intra-and interspecific effects. We find that these genetic correlations might limit the types and strength of interactions that take place across multiple genotypes of the same plant species. Our results suggest that future models of plant-mediated interactions between herbivores should account for patterns of genetic variation and covariation when scaling from individual interactions to population-level processes.

“…The taproot can reach a depth of 240 cm and the roots grow horizontally in soil depths up to 45 cm and become several metres long (Ilnicki & Fertig, 1962). Miyazaki (2008) demonstrated that different sections of the root system had different functions: the bending part forms new shoots; the horizontal part extends into the surrounding area; and the vertical part is used for storage. Shoots are produced from adventitious root buds.…”

“…Solanum carolinense propagates by creeping roots and seeds. The extensive root system consists of a taproot and horizontally growing roots (Ilnicki & Fertig, 1962; Miyazaki, 2008). The taproot can reach a depth of 240 cm and the roots grow horizontally in soil depths up to 45 cm and become several metres long (Ilnicki & Fertig, 1962).…”

“…Creeping perennials are distinguished by having creeping roots, rhizomes, or stolons that elongate and produce new plants from reproductive buds on these organs (Anderson, 1999). The most serious and uncontrollable species are those that develop extensive underground network systems of either rhizomes with determinate buds at the nodes or creeping roots that produce adventitious buds (Ito, 2020; Ito, Inoue, & Ide, 1966; Ito, Takagi, & Yoshino, 2005; Miyazaki, 2008; Tominaga, 2007; Yukinaga, Ide, Ito, & Shimada, 1975). Typical weed species include Solidago altissima , Artemisia indica spp.…”

Increased infestation of aggressive creeping perennial weeds is a significant problem in urban vegetation management programs. These weeds produce vigorous biomass and extensive underground networks of either rhizomes or creeping roots that easily regrow from numerous buds. Foliar application of proper systemic herbicides has been a most effective way to suppress regrowth from underground creeping organs; however, killing the mature plants has disadvantages from aesthetic, economic, and ecological viewpoints. Therefore, we intended to test the possibility of soil‐injection of soil‐active herbicides for effective control of the perennial weeds which develop underground network systems. A pot experiment using combinations of seven species (seven rhizomatous and two having creeping roots) and five chemicals (four herbicides and a plant growth regulator) was conducted to assess whether and how chemicals diffused in soil affect the sprout and growth of buds on creeping organs. All the tested herbicides completely inhibited bud sprouting in one and more species when applied at median or high rates, while most of the flurprimidol‐applied segments sprouted but shoot elongation was significantly reduced. Characteristics of each herbicide were also reflected in the selectivity and features of new outgrowth. The results indicated that chemicals existing in soil were undoubtedly absorbed and affected bud activities. It is concluded that soil injection that delivers the probable soil‐active chemicals to subterranean creeping systems could be a promising technology for controlling noxious creeping perennials.
