Crop disease remains a major problem to global food production. Excess use of pesticides through chemical control measures is serious for sustainable agriculture as we struggle higher crop productivity. The plant growth promoting rhizobacteria (PGPR) proven environment friendly way controlling and increasing yield. PGPR suppress diseases by directly synthesizing pathogen-antagonizing compounds, well triggering immune responses. It possible identify develop that both more stimulate growth, bringing dual benefit. A number have been registered commercial under greenhouse field conditions large strains identified proved effective biocontrol agents (BCAs) environmentally controlled conditions.

Making sense of Integrated Pest Management (IPM) in the light of evolution

Evolutionary Applications, Journal Year: 2020, Volume and Issue: 13(8), P. 1791 - 1805

Published: July 17, 2020

Abstract Integrated Pest Management (IPM) is a holistic approach to combat pests (including herbivores, pathogens, and weeds) using combination of preventive curative actions, only applying synthetic pesticides when there an urgent need. Just as the recent recognition that evolutionary perspective useful in medicine understand predict interactions between hosts, diseases, medical treatments, we argue it crucial integrate framework IPM develop efficient reliable crop protection strategies do not lead resistance development weeds. Such would delay evolution pests, but also optimize each element management increase synergies them. Here, outline key areas within especially benefit from thorough understanding. In addition, discuss difficulties advantages enhancing communication among research communities rooted different biological disciplines researchers society. Furthermore, present suggestions could advance implementation principles thus contribute sustainable agriculture resilient current emerging pests.

Next‐generation biological control: the need for integrating genetics and genomics

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2020, Volume and Issue: 95(6), P. 1838 - 1854

Published: Aug. 14, 2020

ABSTRACT Biological control is widely successful at controlling pests, but effective biocontrol agents are now more difficult to import from countries of origin due restrictive international trade laws (the Nagoya Protocol). Coupled with increasing demand, the efficacy existing and new needs be improved genetic genomic approaches. Although they have been underutilised in past, application techniques becoming feasible both technological economic perspectives. We review current methods provide a framework for using them. First, it necessary identify which trait select what direction. Next, genes or markers linked these traits need determined, including how implement this information into selective breeding program. Choosing can assisted by modelling account proper agro‐ecological context, knowing sufficiently high heritability values. guidelines designing strategies programs, depend on organism, budget, desired objective. Genomic approaches start genome sequencing assembly. guide deciding most strategy agents. Gene discovery involves quantitative loci analyses, transcriptomic proteomic studies, gene editing. Improving practices includes marker‐assisted selection, selection microbiome manipulation agents, monitoring variation during rearing post‐release. conclude identifying promising applications improve biological efficacy.

Abstract The development of biological control methods for exotic invasive pest species has become more challenging during the last decade. Compared to indigenous natural enemies, from area origin are often efficient due their long coevolutionary history with pest. import these well‐adapted species, however, restricted under Nagoya Protocol on Access and Benefit Sharing, reducing number available biocontrol candidates. Finding new agents ways improve important traits (“biocontrol traits”) is therefore crucial importance. Here, we demonstrate potential a surprisingly under‐rated method improvement biocontrol: exploitation intraspecific variation in traits, example, by selective breeding.

Challenges facing arthropod biological control: identifying traits for genetic improvement of predators in protected crops

Pest Management Science, Journal Year: 2020, Volume and Issue: 76(11), P. 3517 - 3526

Published: April 13, 2020

Biological control is an efficient pest method but there are still limitations that hindering its wider adoption. Genetic improvement of biological agents (BCAs) can help to overcome these constraints, the choice key attributes for better performance need be selected open question. Several characteristics have been suggested harsh reality selective breeding BCAs has received a lot attention resulted in very little progress. Identifying appropriate traits prioritized may first step reverse this situation. In our opinion, best way look at factors limiting BCAs, especially generalist predators (pesticide compatibility, prey-density dependence, non-suitable crops, and extreme environmental conditions), according challenges, choose would allow those limitations. The benefits selection higher resistance toxins, whether artificially applied (pesticides) or plant produced (plant defenses); increased fitness when feeding on non-prey food (supplemented plant-derived); adaptation temperature humidity discussed. conclusion, genetic bring about new opportunities biocontrol industry users enhance resilience. © 2020 Society Chemical Industry.

Abstract Biological control of crop pests is considered a good alternative or complement to the use pesticides. However, legislation restricts importation natural enemies pests. A potential way circumvent this limitation by using experimental evolution and/or artificial selection improve native biological agents. Here, we review studies that have used these methodologies and evaluate their success. Experimental has been on wide range traits, with most focusing improving performance in ecologically relevant environments, such as presence pesticides at different temperatures. Although were poorly replicated, selected traits generally improved following process. correlated responses (often form trade‐offs) other interest common. We suggest procedure can be increasing replication performing under more semi‐natural ensure useful are being selected.

Abstract While ecological interactions have been identified as determinant for biological control efficiency, the role of evolution remains largely underestimated in programs. With restrictions on use both pesticides and exotic agents (BCAs), evolutionary optimization local BCAs becomes central improving efficiency resilience control. In particular, we need to better account natural processes fully understand pests BCAs, including biocontrol strategies integrating human manipulations (i.e., artificial selection genetic engineering). agroecosystems, traits performance depends heritable phenotypic variation, trait architecture, strength, stochastic processes, other selective forces. Humans can manipulate these increase likelihood improvement, by artificially increasing strengthening selection, controlling or overpassing through engineering. We highlight facets reviewing recent studies addressing importance then discuss between occurring agroecosystems affecting improved after their release. emphasize that cannot be summarized species pairs because are entangled diverse communities exposed a multitude deterministic forces change rapidly direction intensity. conclude combination different approaches help optimize remain efficient under changing environmental conditions and, ultimately, favor agroecosystem sustainability.
