Indirect interaction between a fungal plant pathogen and a herbivorous beetle of the weed Cirsium arvense

Interactions between plants and their natural enemies are well studied, but investigations on the indirect interactions between plant enemies that simultaneously exploit a host plant are rare. Yet these plant-mediated interactions are important because they may affect not only the impact of plant antagonists on plant survival but may also influence the performance of the other plant exploiters. This study focused on the indirect effects of a systemic infection of creeping thistle, [irsium arvense (L.) Scop., with the necrotrophic fungus Phoma destructiva (Plowr.) on the phytophagous leaf beetle Cassida rubiginosa Müller, by examining egg deposition, food plant choice, and larval and pupal performance of the beetle. Thus, the results give a broader view than most other studies of plant-mediated effects of a pathogen on a phytophagous insect. Since both the beetle and the fungus are considered as agents for the biological control of C. arvense, the results are also of interest for applied ecology. Potted plants of C. arvense were inoculated with a conidiospore suspension of P. destructiva to cause a systemic infection of the plants. In a cage experiment, ovipositing females of C. rubiginosa showed a significant preference for healthy thistles. In dual-choice tests, adults of C. rubiginosa preferred leaf discs from healthy thistles over those from Phoma-infected thistles. The beetles also consumed significantly more leaf tissue from healthy than from infected plants. Development time from freshly hatched larvae until pupation was significantly longer for larvae fed on infected leaves. The weight of last-instar larvae and pupae was lower, and larval and pupal mortality was higher when larvae had been fed with infected compared to healthy leaves. Thus, the combined use of both potential biological control agents may be of lowered efficiency because (1) C. rubiginosa avoided infected thistles for both egg deposition and adult feeding and (2) Phoma infection negatively affected larval development and increased larval and pupal mortality of the beetle.

“…In general, it appears that the dynamics of a C. arvense population involves little in the way of complex interactions, i.e. growth in size and number of the various life history stages are often correlated, and where one component is reduced, so too are all the other components (Donald 1993;Ang et al 1994b). This implies relatively simple relationships between the growth rates of the different parts.…”

Based on a critical review of published research we have developed a conceptual model for a pasture population of Cirsium arvense (Californian thistle) focusing on plausible mechanisms for the regulation of population size: 1) plants overwinter as creeping roots with adventitious buds and subterranean shoots; 2) a main spring cohort of shoots supported by mobilized carbohydrates is regulated numerically by overwintered root mass and apical dominance; 3) shoot death is promoted by interspecific competition, disease and weed control practices; 4) new creeping roots formed throughout the growing season support a low level of shoot recruitment; 5) overwintered root mass is a linear function of photosynthetic opportunity; 6) shoot growth predominates over root growth during the first half of the growing season; 7) root buds, elongating as apical dominance subsides with autumnal shoot senescence, produce the main spring cohort of shoots; 8) creeping root formation is reduced by intraspecific competition; and 9) shoot growth declines with interspecific competition. The validation of these mechanism models should be the focus of ongoing research.

“…A 1-yr greenhouse experiment may be too short for root competition to result in changes in aboveground Canada thistle biomass. Canada thistle shoot biomass fluctuated significantly for the first 2 years of a field study when grown in the presence of plant competitors, and those authors concluded that plant competitors require more than two seasons of growth before they can effectively suppress Canada thistle [28]. Conversely, others report that seeding the competitive exotic grasses perennial ryegrass (Lolium perenne L.), Italian ryegrass (Lolium perenne L. ssp.…”

“…Regardless of the target weed, a lack of competetion from desirable plants post-treatment often leads to reestablishment of unwanted weeds [26,27] , annual ragweed (Ambrosia artemisiifolia L.), common sunflower (Helianthus annuus L.), alfalfa, biennial sweetclover (Melilotus sp. ), and a mixture of perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.) [1,[28][29][30][31][32]. One study reported that the use of competitive grasses for Canada thistle control was as effective as herbicide application over a 3-year period [33].…”

Chemical restrictions, ecological concerns, liability issues, and public sentiment present challenges to land managers attempting to control highly invasive plants like Canada thistle (Cirsium arvense [L.] Scop.). Although herbicide application can be an effective control strategy, increasing limitations force managers of sensitive environments (e.g., national parks, wildlife refuges, protected water-bodies or waterways) to search for effective control alternatives.
