Pathogens, Год журнала: 2022, Номер 11(10), С. 1178 - 1178

Plant-parasitic nematodes (PPNs) are among the most notorious and underrated threats to food security plant health worldwide, compromising crop yields causing billions of dollars losses annually. Chemical control strategies rely heavily on synthetic chemical nematicides reduce PPN population densities, but their use is being progressively restricted due environmental human concerns, so alternative methods urgently needed. Here, we review potential bacterial fungal agents suppress important PPNs, namely Aphelenchoides besseyi, Bursaphelenchus xylophilus, Ditylenchus dipsaci, Globodera spp., Heterodera Meloidogyne Nacobbus aberrans, Pratylenchus Radopholus similis, Rotylenchulus reniformis, Xiphinema index.

A global review of target impact and direct nontarget effects of classical weed biological control

Current Opinion in Insect Science, Год журнала: 2020, Номер 38, С. 48 - 54

Опубликована: Янв. 30, 2020

Recent reviews show that classical weed biocontrol measures can be successful in reducing the negative impacts of invasive plant species, have impressive returns on investment, and contribute to slower rates spread. Quantitative post-release monitoring is necessary account for differences outcomes across spatial temporal scales. Direct nontarget attack (NTA) incidence severity are decreasing over time, pre-release host-specificity tests accurately predict NTA post-release, as long species included testing. Less than 1% was found where impacted had been tested deemed not at risk. Effectiveness environmental safety will likely further improve with incorporation new technologies, such experimental evolutionary studies.

Is Biological Control of Weeds Conservation’s Blind Spot?

The Quarterly Review of Biology, Год журнала: 2023, Номер 98(1), С. 1 - 28

Invasive alien species are among the most important threats to biodiversity, with invasive plants ranking highest. Classical weed biological control—or biocontrol—reunites exotic host-specific natural enemies from their native range aim of controlling plant. We reviewed attention classical biocontrol has received scientific publications for last 30 years, classified according area academia and applied sciences, as well region world. Biological control journals were excluded analyses avoid bias. This process allowed us evaluate support community. also recorded number agents released 1900 date, where they collected, a way analyze evolution policies in different parts releases peaked between 1990 1999, but have declined since, probably due funding issues, increases regulations, bad publicity.

Biological control is an often effective and environmentally friendly method for controlling pests. It can be improved by applying genetic genomic knowledge methodology. In this introduction, we highlight the articles that constitute special issue on how to exploit variation of biocontrol traits molecular techniques increase efficacy agents. We also provide links videos explain concepts biological selective breeding. past decades, human population growth has been source two major concerns: providing sufficient food humanity minimizing worldwide environmental pollution (DeBach & Rosen, 1991). Crop production reduced substantially abiotic biotic stressors, like shortage or excess water, extreme temperatures, low nutrient supply, weeds, pathogens, pests (Oerke, 2006). Although chemical pest essential in achieving great increases crop yields, massive overuse frequent misuse pesticides resulted serious health problems, emergence insects mites resistant these pesticides. a similar way, modification crops build herbicides resistance many concerns, such as indirect use herbicides, development resistance, even negative effects (Magaña-Gómez Calderón de la Barca, 2017; Woodbury et al., 2017). The most successful alternative genetically modified natural enemies (Heimpel Mills, defined living organisms (called enemies) suppress density impact specific organism, making it less abundant damaging than would otherwise (Eilenberg 2001). includes invertebrate using predators, parasitoids weeds herbivores plant pathogens antagonistic micro-organisms induced These used three ways: (1) importation exotic species their establishment new habitat (also called classical control); (2) augmentation established mass periodic colonization (augmentative (3) conservation through manipulation environment (conservation control) While are which they introduced, those augmentative may indigenous (van Lenteren, 2012).

Jekyll or Hyde? The genome (and more) of Nesidiocoris tenuis, a zoophytophagous predatory bug that is both a biological control agent and a pest

Insect Molecular Biology, Год журнала: 2020, Номер 30(2), С. 188 - 209

Опубликована: Дек. 11, 2020

Nesidiocoris tenuis (Reuter) is an efficient predatory biological control agent used throughout the Mediterranean Basin in tomato crops but regarded as a pest northern European countries. From family Miridae, it economically important insect yet very little known terms of genetic information and no genomic or transcriptomic studies have been published. Here, we use linked-read sequencing strategy on single female N. tenuis. this, assembled 355 Mbp genome delivered ab initio, homology-based evidence-based annotation. Along way, bacterial "contamination" was removed from assembly. In addition, lateral gene transfer (LGT) candidates were detected genome. The complete set composed 24 688 genes; associated proteins compared to other hemipterans (Cimex lectularis, Halyomorpha halys Acyrthosiphon pisum). We visualized using various cytogenetic techniques, such karyotyping, CGH GISH, indicating karyotype 2n = 32. Additional analyses include localization 18S rDNA unique satellite probes well pooled assess nucleotide diversity neutrality commercial population. This one first mirid genomes be released agent.
