Phased activity in Heterorhabditis megidis infective juveniles [PDF]

Parasitology, 2002
The infectivity of Heterorhabditis megidis infective juveniles (IJs) increases during storage in water. We investigated whether this change can be related to other features of the IJs' behaviour. IJs were stored in water for 4 weeks at 20 °C, and the following parameters were assessed at intervals: infectivity for Galleria mellonella, dispersal in sand,

NATIVE ENTOMOPATHOGENIC NEMATODES IN THE CULTIVATION OF PRICKLY PEAR IN MILPA ALTA, MEXICO

Tropical and Subtropical Agroecosystems, 2022
Background. Entomopathogenic nematodes (NEP) are found in all ecosystems. Currently, they are one of the most studied ecological alternatives for the biological control of insect pests.

New data on Heterorhabditis bacteriophora Poinar, 1976 from south eastern Iran [PDF]

Iranian Journal of Animal Biosystematics, 2016
During a survey on the entomopathogenic nematodes from Kerman province of Iran, three new populations of Heterorhabditis bacteriophora were recovered from natural areas. Description, measurement and illustration are provided for these isolates. Molecular

Systematics and phylogeny of the entomopathogenic nematobacterial complexes Steinernema-Xenorhabdus and Heterorhabditis-Photorhabdus. [PDF]

Zoological Lett
Entomopathogenic nematodes of the genera Steinernema and Heterorhabditis, along with their bacterial symbionts from the genera Xenorhabdus and Photorhabdus, respectively, are important biological control agents against agricultural pests.

Fatty acid composition of Heterorhabditis sp. during storage [PDF]

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1999
The fatty acid composition of three North West European isolates of Heterorhabditis sp. from different geographical origins, UK211 (England), HF85 (The Netherlands) and EU17 (Estonia) was assessed directly after harvest and, for UK211 and HF85, after 5 weeks storage in water at 20 degrees C. Lipid represented 34-43% of the dry weight of fresh nematodes.

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.

Virulence of entomopathogenic nematodes (Rhabditida: Steinernematidae and Heterorhabditidae) for the control of Diabrotica speciosa germar (coleoptera: chrysomelidae) Virulência de nematoides entomopatogênicos (Rhabditida: Steinernematidae e Heterorhabditidae) para o controle de Diabrotica speciosa germar (coleoptera: chrysomelidae)

Ciência e Agrotecnologia, 2011
Entomopathogenic nematodes (EPNs) are used in biological control of soil insects and show promise in the control of D. speciosa. The objective of this work was to evaluate the potential of native and exotic entomopathogenic nematode isolates in the ...
