Identifying key parameters for reliable assessment of entomopathogenic nematodes viability as affected by spray application stress-related factors. [PDF]

Pest Manag Sci
Commercial entomopathogenic nematodes (EPNs) were exposed to stress simulating spray application conditions, for viability assessment using different methods. Temperature impacted non‐lethal stress earlier than survival and activity, emphasizing the importance of measuring these parameters to assess pesticide application equipment (PAE) impact on EPN ...

How effective are entomopathogenic nematodes for vine weevil (Coleoptera: Curculionidae) biological control? A meta-analysis. [PDF]

Pest Manag Sci
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

Biocontrol potential of naturally occurring entomopathogens against Maladera formosae in corn-soybean rotated systems. [PDF]

Pest Manag Sci
We isolated three insect‐killing nematodes from Maladera formosae infested corn–soybean rotated fields, Heterorhabditis bacteriophora, Pristionchus sp., and Steinernema carpocapsae. Results from greenhouse and field microcosm studies indicate all three nematodes can infect and kill M. formosae grubs and persist through winter.

RNAi-mediated gene silencing of a 26S proteasome subunit increases mortality of the Japanese beetle Popillia japonica. [PDF]

Pest Manag Sci
We propose the regulatory particle non‐ATPase subunit 6 of the 26S proteasome as a first good promising RNA interference target candidate to control the Japanese beetle Popillia japonica. This will help to optimize a double‐stranded RNA insecticide against this priority pest with low off‐target effects on pollinators on a gene sequence‐based prediction.

Soil Sampling and Isolation of Entomopathogenic Nematodes (Steinernematidae, Heterorhabditidae) [PDF]

Journal of Visualized Experiments, 2014
Entomopathogenic nematodes (a.k.a. EPN) represent a group of soil-inhabiting nematodes that parasitize a wide range of insects. These nematodes belong to two families: Steinernematidae and Heterorhabditidae. Until now, more than 70 species have been described in the Steinernematidae and there are about 20 species in the Heterorhabditidae. The nematodes

Compatibility of Heterorhabditis amazonensis MC01 (Nematoda: rhabditida) with fertilizers and soil conditioners

Bioscience Journal, 2019
Entomopathogenic nematodes are natural enemies of insect pests present in the soil; however, the intensive use of agricultural inputs can affect the action of these organisms.

Substrates for storing entomopathogenic nematodes (Rhabditida: Steinernematidae, Heterorhabditidae) [PDF]

Scientia Agricola, 2010
The survival of entomopathogenic nematodes under laboratory conditions is low. With the aim of evaluating substrates to extend the survival of entomopathogenic nematodes, suspensions of Heterorhabditis sp. JPM4 and Steinernema carpocapsae All (3,000 IJ mL-1) were added to dirt, fine sand, coarse sand, foam, expanded clay, phenolic foam, agar, corn ...

iso‐Fatty Acid Metabolism in Caenorhabditis elegans’ Ceramide Biosynthesis

Helvetica Chimica Acta, Volume 106, Issue 11, November 2023., 2023
Abstract Ceramide biosynthesis and its connection to iso‐fatty acid metabolism in the model organism Caenorhabditis elegans was investigated using a combination of reverse genetics and comparative ESI‐(+)‐HR‐MSe ceramide profiling along with incorporation experiments with bacterial mutants specifically enriched with isotopically labeled branched‐chain ...
