Impact of entomopathogenic nematodes on Africanized honey bees Apis mellifera L. (Hymenoptera: Apidae) workers

Semina: Ciências Agrárias, 2020
Africanized honey bee populations (Apis mellifera L.) have been decreasing mainly due to the intense use of synthetic insecticides associated with pollution and climate change.

Genetic Variation in Chemical Defence Affects Protection of an Herbivorous Insect Against Predation

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Genetic variation contributes to intraspecific differences in the chemical defence in many insect species, yet the underlying genetic mechanisms remain poorly understood. The horseradish flea beetle, Phyllotreta armoraciae, sequesters glucosinolates from its horseradish host plant and activates them using endogenous myrosinase enzymes.

Pembiakan Nematoda Patogen Serangga (Rhabditida: Heterorhabditis Dan Steinernema) Pada Media Semi Padat [PDF]

, 2011
Field application of entomopathogenic nematodes (EPN) is still hampered by inefficient mass production. The aim of this study was to compare three published in vitro media (medium Wouts, Bedding and Han) for mass propagation of three indigenous EPNs ...

Biological control potential of North West Himalayan strains of heterorhabditid nematodes against the turnip moth, Agrotis segetum (Denis & Schiffermuller) (Lepidoptera: Noctuidae)

Egyptian Journal of Biological Pest Control, 2018
Himachal Pradesh is a northern state of India and is situated to the southern of the mighty Himalaya. The agro-climatic conditions are conducive for the production of off-season vegetables.

Distinct Morphological Traits of Korean Populations of Pryeria sinica Moore (Lepidoptera: Zygaenidae) Associated With Regional Variation

Entomological Research, Volume 56, Issue 4, April 2026.
ABSTRACT Pryeria sinica Moore is a significant pest of Celastraceae and Pentaphylacaceae plants, causing extensive defoliation in East Asia and beyond. Although its morphological and biological characteristics have been studied in China and Japan, detailed research on the Korean population remains limited.

Secondary Metabolites Produced by Heterorhabditis Symbionts and Their Application in Agriculture: What We Know and What to Do Next

Journal of nematology, 2017
Gram-negative Photorhabdus bacteria have a dual lifestyle: they are mutualists of Heterorhabditis nematodes and are pathogens of insects. Together, this nematode–bacterium partnership has been used to successfully control a wide range of agricultural ...

Susceptibility of Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) to Heterorhabditis sp. (Poinar), Steinernema feltiae (Filipjev) and isolates of entomopathogenic fungi

Egyptian Journal of Biological Pest Control, 2023
Background The weevils Cosmopolites sordidus (Germar), Metamasius hemipterus (Linnaeus), and M. hebetatus (Gyllenhal) (Coleoptera: Curculionidae) form a complex of important pests of plantain crops, causing crop losses of over 60%.

Ecological characterization of Heterorhabditis sonorensis (Caborca strain) (Nematoda: Heterorhabditidae), an entomopathogenic nematode from the Sonoran Desert.

Zoology, 2019
Heterorhabditis nematodes are parasites of a wide range of soil-dwelling insect species. Although these nematodes have been exploited as biological control agents since the last half of the 20th century, much research remains to be done to understand how

Photorhabdus africana sp. nov. isolated from Heterorhabditis entomopathogenic nematodes. [PDF]

Curr Microbiol
AbstractOne Gram-negative, rod-shaped bacterial strain, isolated from an undescribed Heterorhabditis entomopathogenic nematode species was characterized to determine its taxonomic position. The 16S rRNA gene sequences indicate that it belongs to the class Gammaproteobacteria, to the family Morganellaceae, to the genus Photorhabdus, and likely ...
