The effects of intercropping aromatic plants (AP) on behavior and population development of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) were investigated in the field (adults) and in the greenhouse (nymphs). The responses of adults to the volatiles of tomato, Solanum lycopersicum L. (Solanaceae), plants plus AP [T + coriander (Co), rue (R), marigold (M), Greek basil (B), or citronella (Ci)] vs. humidified air or tomato volatiles only were assessed in laboratory Y-tube olfactometer assays. We found higher responses of adult B. tabaci to the humidified air than to the T + Co, T + B, and T + Ci treatments. The responses to T + R and T + M were similar to those to the humidified air. Responses to tomato volatiles were also greater than to T + Co, T + B, and T + Ci. In field assays, populations of adult insects were evaluated in tomato alone, in tomato intercropped with coriander or Greek basil, and in tomato mulched with citronella grass for 6 weeks. Adult whiteflies were generally found in greater numbers in the tomato-alone treatment compared to tomato intercropped with coriander or basil and tomato with citronella grass mulch. Reduction in adult whitefly populations compared to the population found in tomato alone was 84, 79, and 69% in intercrops of T + Co and T + B, and the tomato with citronella mulch treatment, respectively. Infestations of B. tabaci nymphs in plots of tomato plants cultivated alone or intercropped with reseeded coriander plants were also determined in a greenhouse. Nymph counts in the greenhouse assay were generally lower in tomato intercropped with coriander than in tomato alone for all six assessments. The mean reduction in nymphs in tomato intercropped with coriander was 37.7% compared with tomato alone. These results indicate that intercropping aromatic plants reduces infestations of B. tabaci.

“…Results showed that intercropping with aromatic plants contributed to the earlier appearance of natural enemies and the shorter occurrence duration of pests, mainly aphids. Other various aromatic plants ( Mentha canadensis , A. houstonianum , T. patula , and O. basilicum ) have also been used in apple orchards; they increased predator abundance and species richness during the aromatic plants’ flowering period [ 162 ].…”

A potential strategy for controlling pests is through the use of “companion plants” within a crop system. This strategy has been used in several trials to fight against a major crop insect pest: the aphid. We reviewed the literature to highlight the major mechanisms by which a companion plant may act. Trials carried out under laboratory or field conditions revealed that companion plants operate through several mechanisms. A companion plant may be associated with a target crop for various reasons. Firstly, it can attract aphids and draw them away from their host plants. Secondly, it can alter the recognition of the host plant. This effect is mostly attributed to companion plant volatiles since they disturb the aphid host plant location, and additionally they may react chemically and physiologically with the host plant, making it an unsuitable host for aphids. Thirdly, it can attract natural enemies by providing shelter and food resources. In this review, the feasibility of using companion plants is discussed. We conclude that many factors need to be taken into account for a successful companion plant strategy. For the best long-term results, companion plant strategies have to be combined with other alternative approaches against aphids.

“…Moreover, ecosystem stability is crucially dependent on biodiversity (for the diversity-stability relationship see McCann 2000; Proulx et al 2010), as greater diversity may buffer ecosystems against inter-annual environmental variation, particularly among phylogenetically distantly related species, due to the asynchronous population dynamics of resident species (Cadotte, Dinnage & Tilman 2012). In addition, a reduction in plant species richness has been found to increase ecosystem vulnerability to invasions (Bouchard et al 2013;Oakley & Knox 2013), alter herbivore communities (Beizhou et al 2012) and enhance the spread of fungal plant diseases (Knops et al 1999;Pautasso, Holdenrieder & Stenlid 2005). For example, Lau et al (2008) reported a 91% reduction in pathogen infestation of Lespedeza capitata caused by Pythium spp.…”

Tree diversity and the role of non‐host neighbour tree species in reducing fungal pathogen infestation

et al. 2014

The degree to which plant pathogen infestation occurs in a host plant is expected to be strongly influenced by the level of species diversity among neighbouring host and non-host plant species. Since pathogen infestation can negatively affect host plant performance, it can mediate the effects of local biodiversity on ecosystem functioning.We tested the effects of tree diversity and the proportion of neighbouring host and non-host species with respect to the foliar fungal pathogens of Tilia cordata and Quercus petraea in the Kreinitz tree diversity experiment in Germany. We hypothesized that fungal pathogen richness increases while infestation decreases with increasing local tree diversity. In addition, we tested whether fungal pathogen richness and infestation are dependent on the proportion of host plant species present or on the proportion of particular non-host neighbouring tree species.Leaves of the two target species were sampled across three consecutive years with visible foliar fungal pathogens on the leaf surface being identified macro- and microscopically. Effects of diversity among neighbouring trees were analysed: (i) for total fungal species richness and fungal infestation on host trees and (ii) for infestation by individual fungal species.We detected four and five fungal species on T. cordata and Q. petraea, respectively. High local tree diversity reduced (i) total fungal species richness and infestation of T. cordata and fungal infestation of Q. petraea and (ii) infestation by three host-specialized fungal pathogen species. These effects were brought about by local tree diversity and were independent of host species proportion. In general, host species proportion had almost no effect on fungal species richness and infestation. Strong effects associated with the proportion of particular non-host neighbouring tree species on fungal species richness and infestation were, however, recorded.Synthesis. For the first time, we experimentally demonstrated that for two common forestry tree species, foliar fungal pathogen richness and infestation depend on local biodiversity. Thus, local tree diversity can have positive impacts on ecosystem functioning in managed forests by decreasing the level of fungal pathogen infestation.
