Methyl Salicylate Increases Attraction and Function of Beneficial Arthropods in Cranberries.

ABSTRACT: Methyl salicylate (MeSA) is an herbivore-induced plant volatile (HIPV) known to attract the natural enemies of herbivores in agro-ecosystems; however, whether this attraction leads to an increase in natural enemy functioning, i.e., predation, remains largely unknown. Here, we monitored for 2 years (2011-2012) the response of herbivores and natural enemies to MeSA lures (PredaLure) by using sticky and pitfall traps in cranberry bogs. In addition, European corn borer, Ostrinia nubilalis, egg masses were used to determine whether natural enemy attraction to MeSA leads to higher predation. In both years, MeSA increased adult hoverfly captures on sticky traps and augmented predation of O. nubilalis eggs. However, MeSA also attracted more phytophagous thrips and, in 2012, more plant bugs (Miridae) to sticky traps. Furthermore, we used surveillance cameras to record the identity of natural enemies attracted to MeSA and measure their predation rate. Video recordings showed that MeSA lures increase visitation by adult lady beetles, adult hoverflies, and predatory mites to sentinel eggs, and predation of these eggs doubled compared to no-lure controls. Our data indicate that MeSA lures increase predator attraction, resulting in increased predation; thus, we provide evidence that attraction to HIPVs can increase natural enemy functioning in an agro-ecosystem.

Project description:BackgroundCranberries (particularly in the form of cranberry juice) have been used widely for several decades for the prevention and treatment of urinary tract infections. The aim of this review is to assess the effectiveness of cranberries in treating such infections.ObjectivesTo assess the effectiveness of cranberries for the treatment of urinary tract infections.Search strategyThe search strategy developed by the Cochrane Renal Group was used. Also, companies involved with the promotion and distribution of cranberry preparations were contacted; electronic databases and the Internet were searched using English and non English language terms; reference lists of review articles and relevant trials were also searched.Selection criteriaAll randomised or quasi randomised controlled trials of cranberry juice or cranberry products for the treatment of urinary tract infections. Trials of men, women or children were included.Data collection and analysisTitles and abstracts of studies that were potentially relevant to the review were screened by one reviewer, RJ, who discarded studies that were clearly ineligible but aimed to be overly inclusive rather than risk losing relevant studies. Reviewers RJ and LM independently assessed whether the studies met the inclusion criteria. Further information was sought from the authors where papers contained insufficient information to make a decision about eligibility.Main resultsNo trials were found which fulfilled all of the inclusion criteria. Two trials were excluded because they did not have any relevant outcomes.Reviewer's conclusionsAfter a thorough search, no randomised trials which assessed the effectiveness of cranberry juice for the treatment of urinary tract infections were found. Therefore, at the present time, there is no good quality evidence to suggest that it is effective for the treatment of urinary tract infections. Well-designed parallel group, double blind trials comparing cranberry juice and other cranberry products versus placebo to assess the effectiveness of cranberry juice in treating urinary tract infections are needed. Outcomes should include reduction in symptoms, sterilisation of the urine, side effects and adherence to therapy. Dosage (amount and concentration) and duration of therapy should also be assessed. Consumers and clinicians will welcome the evidence from these trials.
