Depending on its accuracy, this approach represents a major advance in the rapid detection of the pinewood #nematode.

Fig. 1. The scheme of generating and testing rhizosphere microbial inoculants in this study. Soybean cyst nematode (SCN)-susceptible cultivars were Dickey, Rolette, IA2104RA12, IA3054RA12, and Williams 82; SCN-resistant cultivars were ND17-22117, ND17-20565, IAR1903SCN, IAR2801SCN, and Jack.
New findings from Chuntao Yin and Nathan Lahr demonstrate that soybeans recruit beneficial soil microbes to defend against the devastating soybean cyst #nematode. Read the press release to learn more: https://bit.ly/4cw2v9d

A conceptual model showing delivery of stylet-secreted effectors into a selected soybean Glycine max root cell by the soybean cyst nematode (SCN) Heterodera glycines that interact with wild-type soluble N-ethylmaleimide-sensitive factor (NSF) attachment proteins (α-SNAPs) to promote cellular vesicular trafficking activity necessary for feeding cell formation.

Nematode under my new microscope (Olympus BX41) at 200x magnification + digital crop
The same nematode under my old scope (Swift SW380T) at the same magnification
Definitely an upgrade over my old scope! (The same nematode under both scopes)
Left: new scope
Right: old scope
P.S. photos are taken through an eye piece with my phone. I’m still gonna get an adapter for my camera, so I should get results even better! :D

A, Vacuole-like structures in SCN eggs. B, Vacuole-like structures in enclosed first-stage juveniles and emerging second-stage juveniles (J2s). C, Vacuole-like structures in hatched J2s. D, Hatched J2s in potato dextrose broth (PDB) control without vacuole-like structures. E, Eggs in PDB control. Scale bar = 45 µm.
Biological control of soybean cyst #nematode (SCN) using fungi associated with cyst nematodes shows promise. Vijay Kunwar et al. screened 75 fungal isolates across 55 species associated with different cyst nematodes to assess antagonistic effects on SCN: https://doi.org/10.1094/PHYTO-03-25-0094-R

🌲 We show that managing PWD is ecologically complex & that focusing on a single cause is detrimental.

🌲 For 27 yrs, Europe's response to the PWN stayed the same: 🪓🔥. Millions spent on diagnostics & buffer zones, yet the #nematode spread from 🇵🇹 to 🇪🇸 and now 🇫🇷.
Diagnostics matter, but aren't a cure.
Time to fund solutions: biocontrol & long-term management.
Buffer zones failed. Science didn't. 🔬✅
Fig. 2. Sting nematode soil population densities as influenced by fumigant and nonfumigant nematicide treatments in 2022 field trial. “UTC” is untreated control; “MP 125kg” and “MP 293kg” are metam potassium at 125 and 293 kg a.i./ha, respectively; “MP125+FLN” is metam potassium at 125 kg a.i./ha mixed with fluensulfone; and “1,3-D 66kg” is 1,3-dichloropropene at 66 kg a.i./ha. Within each subfigure, means with different letters are significantly different (Fisher’s protected least significant difference, α = 0.05). Bars and brackets represent means (n = 6) and standard errors, respectively.
Sting nematode is a yield-limiting plant-parasitic #nematode in Florida potato production and often managed using 1,3-dichloropropene fumigation. Zane Joseph Grabau et al. tested the efficacy of alternative nematicides and nematicide rates: https://doi.org/10.1094/PDIS-12-24-2626-RE

Figure 1 in Ma et al. (2025): "The schematic diagram of the experimental design in Songnen meadow steppe. The study area is characterized as a mosaic of high-salinity and low-salinity patches. The experiment was conducted as a completely randomized block design with nine 25 m × 25 m paddocks being arranged into three blocks. Each block consisted of three grazing treatments: cattle grazing, sheep grazing and ungrazing as a control. From 2017 to 2020, a total of three mature cattle with an average body weight of 350.0 ± 10.5 kg or fifteen sheep with an average body weight of 35.0 ± 1.6 kg were grazed during the initial 2 weeks of each month from June to August, producing comparable moderate intensities."

Figure 2 in Chen et al. (2025): "Co-occurrence networks of relationships among soil nematode genera under (a and b) control and irrigation treatment (i.e., across degradation levels and nitrogen fertilization treatments, n = 30), and (c and d) control and nitrogen fertilization (i.e., across degradation levels and irrigation treatments, n = 30), and (e–g) in the lightly degraded, moderately degraded and severely degraded grasslands (i.e., across irrigation treatments and nitrogen fertilization treatments, n = 20). Nodes represent different nematode genera, and red, yellow, green and blue nodes represent bacterivores, fungivores, plant parasites and omnivores-predators, respectively. Red lines represent positive correlations between genera, while blue lines represent the negative correlations, and the thickness of the connecting line represents the strength of the correlation effect. Node size is positively correlated with node degree."
