Molecular Characterization of Entomopathogenic Bacteria, Bacillus thuringiensis [PDF]

Journal of Plant Protection and Pathology, 2018
The genetic variation of the new Bacillus thuringiensis isolate from soil and (Agrin) as a reference were evaluated by using random amplified polymorphic (RAPD-PCR) in order to distinguish between the isolates using random primers. It was noticed that; 1- Genetically, B.t .isolate is the closest to Agrin which is a commercial product of B.t., 2 ...

How effective are entomopathogenic nematodes for vine weevil (Coleoptera: Curculionidae) biological control? A meta‐analysis

Pest Management Science, Volume 82, Issue 4, Page 3427-3438, April 2026.
Entomopathogenic nematodes provide reliable biological control of vine weevil larvae, reducing populations by 63% on average. All five tested species are effective, with temperature (18–30 °C) being the strongest predictor of success. Abstract BACKGROUND Vine weevil (Otiorhynchus sulcatus) is a globally important pest of soft fruit and ornamental crops

Non-symbiotic association of Citrobacter freundii and Staphylococcus succinus with the entomopathogenic nematode Steinernema feltiae [PDF]

نامه انجمن حشره‌شناسی ایران, 2016
Soil-dwelling nematodes from Steinernematidae family are obligate parasites of insects and usually referred to as entomopathogenic nematodes (EPNs). These nematodes are symbiotically associated with entomopathogenic bacteria Xenorhabdus spp.

Inhibition of Spodoptera frugiperda phenoloxidase activity by the products of the Xenorhabdus rhabduscin gene cluster.

PLoS ONE, 2019
We evaluated the impact of bacterial rhabduscin synthesis on bacterial virulence and phenoloxidase inhibition in a Spodoptera model. We first showed that the rhabduscin cluster of the entomopathogenic bacterium Xenorhabdus nematophila was not necessary ...

Towards a Novel Biocontrol Strategy: High Performance of Optimised Cell Wall‐Degrading Enzymes Secreted by Escovopsis primorosea LBM 277

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Escovopsis primorosea LBM 277 efficiently produced proteases, β‐1,3‐glucanases and chitinases under submerged fermentation using Leucoagaricus gongylophorus cell walls and Mandels complex. RSM‐BBD optimization significantly increased enzyme activity. The enzymatic cocktail remained stable for 30 days at room temperature and pH 4–6, aligning with the ...

The genome and stage‐specific transcriptomes of the carrot weevil, Listronotus oregonensis, reveal adaptive mechanisms for host specialisation and symbiotic interactions

Insect Molecular Biology, Volume 35, Issue 2, Page 126-138, April 2026.
Comprehensive genome and stage‐specific transcriptomes reveal 14,637 genes in Listronotus oregonensis, advancing genetic insights into a key agricultural pest. Compared with related species, L. oregonensis exhibits reduced chemoreceptor gene families but expanded detoxification gene clusters, reflecting its narrow host range and adaptability.

Associated bacteria of a pine sawyer beetle confer resistance to entomopathogenic fungi via fungal growth inhibition

Environmental Microbiome, 2022
Background The entomopathogenic Beauveria bassiana is a popular fungus used to control the Japanese pine sawyer, Monochamus alternatus Hope, the key vector of pine wood nematode (Bursaphelenchus xylophilus) that is the causal agent of pine wilt disease ...
