DOI: https://doi.org/10.1016/j.biocontrol.2020.104329 Interpretive Summary: In this research we found that a beneficial fungus normally found in corn plants can help to control Fusarium head blight (FHB). FHB is a devastating fungal disease of wheat and barley worldwide. Grain harvested from infected crops can be contaminated with harmful toxins produced by the fungal pathogen. These toxins devalue the grain and make it unsafe for eating. A potential method to control FHB is the use of beneficial fungi that naturally live inside the plant tissues and produce compounds that inhibit the growth of other fungi or increase plant immunity. In this study, Sarocladium zeae, a fungus known to produce antifungal compounds, was tested for its ability to colonize wheat. Strains of S. zeae successfully colonized internal wheat organs and survived within the plant through its life cycle. Wheat plants with S. zeae were more resistant to FHB. This fungus is a promising candidate for environmentally friendly ...
The introduction of biological control agents to new environments requires host specificity tests to estimate potential non-target impacts of a prospective agent. Currently, the approach is conservative, and is based on physiological host ranges determined under captive rearing conditions, without consideration for ecological factors that may influence realized host range. We use historical data and current field data from introduced parasitoids that attack an endemic Lepidoptera species in Hawaii to validate a probabilistic risk assessment (PRA) procedure for non-target impacts. We use data on known host range and habitat use in the place of origin of the parasitoids to determine whether contemporary levels of non-target parasitism could have been predicted using PRA. Our results show that reasonable predictions of potential non-target impacts may be made if comprehensive data are available from places of origin of biological control agents, but scant data produce poor predictions. Using apparent

Sirex noctilio is a major pest to Pinus spp. and threat to the Forestry industry in the Southern Hemisphere. The varying level of efficacy of its primary biological control agent, Deladenus siricidicola, is also of serious concern. There is a need to better understand the diversity of both the pest and its biological control agent, as one of the factors that could influence this biological control system. One of the short‐comings is that molecular markers did not exist to study the population diversity of the nematode and wasp. As part of this study it was illustrated how next generation sequencing (454 pyrosequencing) can be used to enhance microsatellite marker discovery tools, and produce a more robust, rapid and economical tool for the development of these markers. The developed markers for D. siricidicola and S. noctilio proved to be highly efficient in characterizing the population diversity of both of these organisms.It was shown that the populations of D. siricidicola in the Southern ...
Term and definition not yet included in the Glossary of Phytosanitary Terms.. OUTLINE OF REQUIREMENTS. A pest free area is an area in which a specific pest does not occur as demonstrated by scientific evidence and in which, where appropriate, this condition is being officially maintained.. The establishment and use of a PFA by an NPPO provides for the export of plants, plant products and other regulated articles from the country in which the area is situated (exporting country) to another country (importing country) without the need for application of additional phytosanitary measures when certain requirements are met. Thus, the pest-free status of an area may be used as the basis for the phytosanitary certification of plants, plant products and other regulated articles with respect to the stated pest(s). It also provides, as an element in pest risk assessment, the confirmation on a scientific basis of the absence of a stated pest from an area. The PFA is then an element in the justification of ...

Biological Trace Element Research. 148(3):356-362. Interpretive Summary: Dietary iron is an extremely important nutrient required by animals to, among many other things, fight off fatal infections. But pest insects also require iron and may actually benefit from iron biofortification intended for humans and livestock. Therefore it is important to determine whether iron levels present in crops help or hinder the usefulness of an insect virus used as a biological control agent for an insect pest. Very little is presently known about the iron requirements of pest insects, thus we conducted the first study of blood and tissue iron levels in budworm caterpillars following infection with two viral biological control agents. Viral infection of caterpillars greatly increased the blood levels of iron, especially in the late stages of infection. Trace ...

In order to make potatoes more resistant, researchers want to coat the seeds of the nightshade plants with beneficial fungi and thus help them grow.
The mechanical force that a single fungal cell or bacterial colony exerts on a plant cell may seem vanishingly small, but it plays a key role in setting up some of the most fundamental symbiotic relationships in biology. In fact, it may not be too much of a stretch to say that plants may have never moved onto land without the ability to respond to the touch of beneficial fungi, according to a new study led by Dr. Jean-Michel Ané, a professor of agronomy at the University of Wisconsin-Madison. Many people have studied how roots progress through the soil, when fairly strong stimuli are applied to the entire growing root, says Dr. Ané, who just published a review of touch in the interaction between plants and microbes in the August 2014 issue of Current Opinion in Plant Biology. We are looking at much more localized, tiny stimuli on a single cell that is applied by microbes. Specifically, Dr. Ané, Dr. Dhileepkumar Jayaraman, a postdoctoral researcher in agronomy, and Dr. Simon Gilroy, a ...

Take the breathing space the season is naturally offering us and clear only what is needed to keep chaos in check.. Trees and shrubs are showing you their limbs now that the foliage is down. There are mixed opinions about the viability of dead wood in a garden - some say it is a vector for honey fungus - but I prefer to take the risk. Healthy trees and shrubs will not be prone if they are kept in good condition and there are plenty of other beneficial fungi that need a place to call their own.. Our neighbour down at the farm believes in the same principle. From time to time one of his elderly poplars has come crashing across the brook that divides us. Although I have been happy to have the wood, I left the first tree that came down for the air of wildness that it lent the field. We cleared the ...

To increase the ability of this water to stay around in the dry season, carbonaceous woody debris material (again, what would otherwise be fuel load) can be used to pack water retention structures placed in the landscape. Water retention structures can be a contour ditch, seasonal pool or rain garden and are ideally placed to capture surface runoff from roads or other structures. Again, the material must have ground contact and not be sticking up above the natural grade to avoid adding to fire danger. We can even inoculate these systems with desirable and beneficial fungi in order to yield edible mushroom crops and aid in decomposition where pollution is not present.

A device and method of placement of a chronic micro-catheter is shown that allows effective guiding of micro-catheters through a host catheter that is later removable while leaving the micro-catheter implanted in place within the patient. The novel configuration allows the micro-catheter to be completely radially enclosed during insertion, and still allows the host catheter to be removed, leaving the micro-catheter behind. Additionally, the configuration allows several micro-catheters to be placed at any number of depths and orientations while still using a minimally invasive host catheter.

The work developed in this thesis aimed to increase understanding about the variability and stability in eleven biotypes of Pochonia chlamydosporia, a facultative parasitic fungus with potential as a biological control agent against root-knot (Meloidogyne spp.), false root-knot (Naccobus spp.) and cyst nematodes (Heterodera and Globodera, spp.). Differences in performance were assessed by measuring saprophytic and parasitic growth using in vitro bioassays. Information on virulence (in vitro) was collected for a range of biotypes with the objective to relate in vitro parasitic growth with rhizosphere colonisation ability and secretion of extracellular enzymes. Results showed differences between biotypes in their ability to colonise the rhizosphere of plants, parasitise nematode eggs and to produce a range of extracellular enzymes but no significant relationships were found between saprophytic or parasitic growth and enzyme production. For the first time, the specific activity of protease, ...
The main effects of antagonistic rhizobacteria on plant pathogenic fungi are antibiosis, fungistasis or an indirect constraint through the induction of a plant defence response. To explore different biocontrol mechanisms, an in vitro confrontation assay was conducted with the rhizobacterium Pseudomonas fluorescens Pf29Arp as a biocontrol agent of the fungus Gaeumannomyces graminis var. tritici (Ggt) on wheat roots. In parallel with the assessment of disease extension, together with the bacterial and fungal root colonization rates, the transcript levels of candidate fungal pathogenicity and plant-induced genes were monitored during the 10-day infection process. The bacterial inoculation of wheat roots with the Pf29Arp strain reduced the development of Ggt-induced disease expressed as attack frequency and necrosis length. The growth rates of Ggt and Pf29Arp, monitored through quantitative polymerase chain reaction of DNA amounts with a part of the Ggt 18S rDNA gene and a specific Pf29Arp strain detection
The objective of this research was to identify bacterial spot-causing pathogen and bacterial antagonists for management of the disease using biocontrol agents as environmentally friendly alternatives. Isolates of Bacillus spp. were obtained from the soil samples collected at different localities in Serbia. Antibacterial activity of natural antagonists toward the pathogen isolated from infected pepper leaves was examined using a modified well-diffusion assay and standard germination test. Our results confirmed the presence of Xanthomonas euvesicatoria as the causal agent of bacterial spot of pepper. Screening of 32 Bacillus spp. isolates for antibacterial activity showed that 8 isolates inhibit growth of examined X. euvesicatoria isolates. Four isolates identified as Bacillus subtilis exhibited the highest antibacterial activity by in vitro test (from 5 to 14 mm inhibition zone of bacterial growth). The isolates positively influenced germination of pepper seeds, causing up to 16% and 70% increase ...
In 2008, a field survey was conducted in northern Argentina to collect natural enemies of Cestrum species (Solanaceae) for use as biological control agents in South Africa. The rust fungus Uromyces cestri Bertero ex Mont. (Pucciniales: Pucciniaceae) was found on Cestrum parqui L'Hér. and imported into quarantine facilities in South Africa. No damaging pathogens were found on Cestrum laevigatum Schltdl. Preliminary host-range studies showed that U. cestri was able to infect and cause disease on C. parqui and on Cestrum elegans (Brongn. ex Neumann) Schltdl. in South Africa, and could have potential for the biological control of these species. The rust did not infect any of the other Cestrum species tested, and neither did it infect C. laevigatum which is the most problematic Cestrum species in South Africa.

Strain UFB2 was isolated from a soybean field soil in Mississippi and identified as a member of Pseudomonas chlororaphis. Strain UFB2 has a broad-spectrum antimicrobial activity against common soil-borne pathogens. Plate assays showed that strain UFB2 was especially efficient in inhibiting the growth of Clavibacter michiganensis 1-07, the causal agent of the devastating bacterial canker of tomato. Here, the complete genome sequence of P. chlororaphis strain UFB2 is reported and described. The strain UFB2 genome consists of a circular chromosome of 6,360,256 bp of which 87.86 % are protein-coding bases. Genome analysis revealed multiple gene islands encoding various secondary metabolites such as 2,4-diacetylphloroglucinol. Further genome analysis will provide more details about strain UFB2 antibacterial activities mechanisms and the use of this strain as a potential biocontrol agent.

But the indiscriminate use of chemical pesticides to minimize disease infestation especially during seed germination stage remains to be a formidable challenge for our local farmers today. To address this long-standing problem, a study on the use of Trichoderma as a control agent of damping-off disease in vegetable was conducted by a research group headed by Dr. Virginia C. Cuevas at UP Los Banos. The project, which wa supported by the Bureau of Agricultrual Research (BAR), determined the efficacy of Tricoderma as a biological control agent against the pre emergent and post-emergent damping off diseases in lowland vegetables. The damping off diseases, usually caused by fungal pathogens under moist or damp conditions are fatal to seedlings.. ...
The TaQ alleles as one of the AP2-like transcription factors in common wheat (Triticum aestivum) play an important role in the evolution of spike characteristics from wild and domesticated emmer to modern wheat cultivars. Its loss-of-function mutant not only changed threshability and spike architecture but also affected plant height, flowering time, and floret structure. However, the comprehensive functions of TaAQ and TaDq genes in wheat have not been fully elucidated yet. Here, CRISPR/SpCas9 was used to edit wheat TaAQ and TaDq. We obtained homozygous plants in the T1 generation with loss of function of only TaAQ or TaDq and simultaneous loss of function of TaAQ and TaDq to analyze the effect of these genes on wheat spikes and floret shapes. The results demonstrated that the TaAQ-edited plants and the TaAQ and TaDq simultaneously-edited plants were nearly similar in spike architecture, whereas the TaDq-edited plants were different from the wild-type ones only in plant height. Moreover, the ...
An impulsive model of augmentative biological control consisting of a general continuous predator-prey model in ordinary differential equations augmented by a discrete part describing periodic introductions of predators is considered. It is shown that there exists an invariant periodic solution that corresponds to prey eradication and a condition ensuring its global asymptotic stability is given. An optimisation problem related to the preemptive use of augmentative biological control is then considered. It is assumed that the per time unit budget of biological control (\ie the number of predators to be released) is fixed and the best deployment of this budget is sought after in terms of release frequency. The cost function to be minimised is the time taken to reduce an unforeseen prey (pest) invasion under some harmless level. The analysis shows that the optimisation problem admits a countable infinite number of solutions. An argumentation considering the required robustness of the optimisation result
DUGi: Viewing Item from repository Recercat: The presence of the antimicrobial peptide (AMP) biosynthetic genes srfAA (surfactin), bacA (bacylisin), fenD (fengycin), bmyB (bacyllomicin), spaS (subtilin), and ituC (iturin) was examined in 184 isolates of Bacillus spp. obtained from plant environments (aerial, rhizosphere, soil) in the Mediterranean land area of Spain. Most strains had between two and four AMP genes whereas strains with five genes were seldom detected and none of the strains had six genes. The most frequent AMP gene markers were srfAA, bacA, bmyB, and fenD, and the most frequent genotypes srfAA-bacA-bmyB and srfAAbacA-bmyB-fenD. The dominance of these particular genes in Bacillus strains associated with plants reinforces the competitive role of surfactin, bacyllomicin, fengycin, and bacilysin in the fitness of strains in natural environments. The use of these AMP gene markers may assist in the selection of putative biological control agents of plant pathogens

Although the vast majority of biological control agents is generally regarded as safe for humans and environment, the increased exposure of agriculture workers, and consumer population to fungal substances may affect the immune system. Those compounds may be associated with both intense stimulation, resulting in IgE-mediated allergy and immune downmodulation induced by molecules such as cyclosporin A and mycotoxins. This review discusses the potential effects of biocontrol fungal components on human immune responses, possibly associated to infectious, inflammatory diseases and defective defenses.
Trichoderma is a genus of soil-borne fungi displaying a remarkable spectrum of bio-activity.. The ability of selected Trichoderma spp (strains) to directly antagonize plant pathogens AND to stimulate plant growth and defence responses has led to their widespread use in agriculture both for disease control and yield increases..

The most beneficial fungi, called mycorrhizae, were found immediately around the trees roots or rhizosphere. Among these good bacteria was a group classified as growth promoters, which support development and protect the plant against pathogenic attacks. They also supported the production of phytohormones, which aid the supply of nutrients and water.. When mycorrhizal fungi came in contact with the plants roots, they began biochemical communication that allowed trees to adapt during transplantation without a problem. The microorganism was also responsible for deeper exploration into the soil and brought useful elements to the plant such as phosphorus.. Plants that contained mycorrhizae also achieved more efficient photosynthesis and needed less water to function, Olalde Portugal said.. Not all bacteria provided the same benefits, however. Distinct strands were selected to provide benefits to the different trees in the study.. www.freshfruitportal.com. ...

Biological control can play a major role in a resilient cultivation system, by using natural enemies of fungi, bacteria and pest insects. It is possible to design a cultivation system that is largely able to contain diseases and pests on its own with biological control. This largely dispenses with the need for chemical crop protection.
Since early times the sound production by stridulation in spiders has attracted the attention of arachnologists (POCOCK, 1895 a, b) . As in insects, these organs consist of two opposite surfaces which rub one against the other, which are located in several parts of body of the spider (UETZ & STRATTON, 1982). LEGENDRE (1963) attributed to Westring (1843) the first description of a feature with such probable function in Theridiidae, but the first audible sound was reported for spider by WOOD-MASON (1876) for the Indian theraphosid Chilobrachys stridulans (Wood-Mason, 1875). Up to now, several features were described and classified in tarantulas as stridulatory organs (for revisions see CHRYSANTHUS, 1953; LEGENDRE, 1963; UETZ & STRATTON, 1982). In fact, these organs were widely used in the systematics of Theraphosidae (POCOCK, 1895 a, b, 1897, 1899; SIMON, 1903; PÉREZ-MILES et al., 1996; SCHMIDT, 1999, 2000). The tarantulas present high diversity of such features among the spiders, but the ...

Khandelwal and colleagues succeeded in identifying the insecticidal factor. The active component was found in a large complex normally associated with the bacterial outer membrane, and was also present in or on outer membrane vesicles (OMVs) released from the bacterial surface, says Khandelwal. They then searched through OMV components and identified a small (17 kDa) toxic protein. When purified, this protein was toxic to cultured larval cells and directly killed H. armigera larvae. Gene cloning and sequencing showed this protein is related to a class of bacterial outer membrane proteins that form protrusions, called pili or fimbriae, which often help bacteria attach to host cells during infection. Similar to pili proteins, the purified 17 kDa protein self-associated to form oligomers, each of which was connected to the next by a strand. Most importantly, the recombinant 17 kDa protein killed H. armigera larvae, demonstrating its potential as a biological control agent in a world desperately in ...

See how those flies are hovering around the heads of the ants? Thats where they lay their eggs… in the heads of their hosts. They approach them from behind and jam their ovipositior where the head and neck meet and inject their eggs directly into the ants head capsule. The larvae of the fly then hatch and hollow the head out, consuming the muscles and brain. Those ants will eventually become dis coordinated and then start to wander aimlessly when the larva inside consumes the ants brain, as this is kind of the default mode of decapitated insects. The ants head will eventually fall off when the maggot is ready to pupate because the larva releases an enzyme that causes this to happen. The fly will complete its development in the ants head by transforming into its inactive pupal stage, then emerges as an adult after a few more weeks. Most of this flys life cycle takes place in an ants head ...
