Frequency of occurrence and identification of nematodes among entomopathogenic organisms in agrocoenoses of Ukraine

open access: yesGeo&Bio, 2023
The research objects were entomopathogenic organisms (Nematoda, Fungi, Bacteria, and Insecta) collected in agrocoenoses in different regions of Ukraine during 2016–2018 and 2020–2021.

The study of receptivity of Colorado potato beetle Leptinotarsa decemlineata Say, 1824 to the entomopathogenic nematode Heterorhabditis bacteriophora Poinar, 1975 [PDF]

open access: yesКавказский энтомологический бюллетень, 2009
Possibility of receptivity of Colorado potato beetle (CPB) Leptinotarsa decemlineata Say, 1824 by entomopathogenic nematode Heterorhabditis bacteriophora Poinar, 1975 was studied. The larvae of infected CPB was used.

Enhanced efficacy of pheromone-treated entomopathogenic nematodes against whiteflies in foliar applications with a gel adjuvant

open access: yesBiological Control
The whitefly, Bemisia tabaci, has a diverse host range that includes many economically important crops. Plant damage and crop loss resulting from infestations of this insect pest averages >$140 million (USD) annually in the southeast U.S.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Matrine–Tea Saponin Synergism Involves Suppressed Detoxification and Digestion in a Leaf Beetle

open access: yesIntegrative Zoology, EarlyView.
Tea saponin and matrine showed synergistic toxicity against Plagiodera versicolora. Combined exposure suppressed digestion‐ and detoxification‐related processes, while silencing the trypsin gene Pver105950 and chitinase gene Pver001190 increased larval susceptibility to tea saponin and matrine, respectively.

The entomopathogenic nematode Heterorhabditis megidis: host searching behaviour, infectivity and reproduction [PDF]

open access: yes, 2001
Entomopathogenic nematodes in the families Heterorhabditidae and Steinernematidae have considerable potential as biological control agents of soil-inhabiting insect pests.

Heterorhabditis bacteriophora (Poinar) - the first member from Heterorhabditidae family in Slovenia

open access: yesActa Agriculturae Slovenica, 2009
In August 2008, we examined 95 soil samples for the occurrence of entomopathogenic nematodes in eastern part of Slovenia. 11 samples from 9 different locations were positive to entomopathogenic nematodes, but to this time only sample D54 was analysed ...

Exploiting Native Biodiversity for Invasive Species Management: The Case of Exorista larvarum as a Natural Enemy of the Invasive Box Tree Moth Cydalima perspectalis

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The investigations evaluated the performance of the native parasitoid Exorista larvarum (L.) on last instar Cydalima perspectalis (Walker) larvae, using the factitious host Galleria mellonella (L.) as a control. Laboratory bioassays were conducted using no‐choice and choice (1:1 and 5:5) experimental designs.

The evolution of entomopathogeny in nematodes

open access: yesEcology and Evolution
Understanding how parasites evolved is crucial to understand the host and parasite interaction. The evolution of entomopathogenesis in rhabditid nematodes has traditionally been thought to have occurred twice within the phylum Nematoda: in ...

Multitrophic Effects of Belowground Parasitoid Learning

open access: yesScientific Reports, 2017
The ability to learn allows organisms to take advantage of dynamic and ephemeral opportunities in their environment. Here we show that learning in belowground entomopathogenic nematodes has cascading multitrophic effects on their hosts, other nematodes ...
