Electronic address:

Changes in the cell type composition of the digestive gland epithelium constitute a common and recognized biological response to stress in mussels. Usually, these changes are identified as alterations in the relative proportion of basophilic cells, determined in tissue sections stained with hematoxylin-eosin (H&E) and measured in terms of volume density of basophilic cells (Vv) after stereological quantification. However, the identification and discrimination of basophilic cells may be a difficult issue, even for a trained operator, especially when, in circumstances of environmental stress, basophilic cells lose their basophilia and the perinuclear area of digestive cells gains basophilia.

Two species of microsporidia have been described from lady beetles that are commercially available for biological control: Nosema adaliae from the two-spotted lady beetle, Adalia bipunctata L., and Tubulinosema hippodamiae from the convergent lady beetle, Hippodamia convergens Guérin-Méneville. These pathogens delay larval development under controlled conditions, but little is known regarding the effects that microsporidia cause when their hosts are subjected to stressful conditions that are often experienced in nature.

Temperature-driven changes in viral loads in the honey bee Apis mellifera.

J Invertebr Pathol 2019 Jan 11;160:87-94. Epub 2018 Dec 11.

INRA, UR 406 Abeilles et Environnement, Site Agroparc, Domaine St Paul, 228, Route de l'aérodrome CS40509, 84914 Avignon Cedex 9, France.

Many of the physiological traits in insects are shaped by environmental temperatures, which can influence their interactions with pathogens. Therefore, quantifying the thermal responses of the host-pathogen system is crucial for better understanding and predicting their dynamics due to environmental changes. This is particularly important in honey bees, which are experiencing severe colony losses around the world, notably due to infection with the Deformed wing virus (DWV). Read More

Toxicity of phenolic compounds to entomopathogenic nematodes: A case study with Heterorhabditis bacteriophora exposed to lentisk (Pistacia lentiscus) extracts and their chemical components.

J Invertebr Pathol 2019 Jan 4;160:43-53. Epub 2018 Dec 4.

Department of Entomology and Nematology, Agricultural Research Organization, The Volcani Center, Bet Dagan 50250, Israel.

Insects show adaptive plasticity by ingesting plant secondary compounds, such as phenolic compounds, that are noxious to parasites. This work examined whether exposure to phenolic compounds affects the development of insect parasitic nematodes. As a model system for parasitic life cycle, we used Heterorhabditis bacteriophora (Rhabditida; Heterorhabditiade) grown with Photorhabdita luminescens supplemented with different concentrations of plant phenolic extracts (0, 600, 1200, 2400 ppm): a crude ethanol extract of lentisk (Pistacia lentiscus) or lentisk extract fractionated along a scale of hydrophobicity with hexane, chloroform and ethyl acetate; and flavonoids (myricetin, catechin), flavanol-glycoside (rutin) or phenolic acids (chlorogenic and gallic acids).

State Key Laboratory for Biology of Plant Diseases and Insect Pests, Key Laboratory of Integrated Pest Management in Crops, Ministry of Agriculture, Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Beijing, PR China. Electronic address:

We characterize a novel picorna-like virus, named Helicoverpa armigera Nora virus (HaNV), with a genome length of 11,200 nts, the sequence of which was isolated from the lepidopteran host cotton bollworm Helicoverpa armigera, using RNA-Seq. Phylogenetic analysis, using the putative amino acid sequence of the conserved RNA-dependent RNA polymerase (RdRp) domain, indicated that HaNV clustered with Spodoptera exigua Nora virus, Drosophila Nora virus and Nasonia vitripennis virus-3 with a high bootstrap value (100%), which might indicate a new viral family within the order Picornavirales. HaNV was efficiently horizontally transmitted between hosts via contaminated food, and transmission was found to be dose-dependent (up to 100% efficiency with 10 viral copy number/µl). Read More
