Which came first: the disease or the pest? Is there a host mediated spread of Beauveria bassiana (Ascomycota: Hypocreales) by invasive palm pests?

J Invertebr Pathol 2019 Feb 5. Epub 2019 Feb 5.

Department of Agricultural and Forestry Sciences, ETSIAM, University of Cordoba. Campus de Rabanales. Edificio C4 Celestino Mutis. 14071. Cordoba, Spain. Electronic address:

The red palm weevil (RPW) Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae) is threatening the palm family worldwide, causing important economic losses. Current tactics to manage the weevil are largely based on chemical control, although the use of pesticides is hampered by several environmental constraints. Since the first introduction of RPW in Spain in 1996 and during its progressive spread around the Mediterranean basin, the number of reports of natural infection of RPW populations by entomopathogenic fungi (EPF) has been rising for 15 years, and this rise could support a pest-mediated EPF spread.

Enhanced discrimination of basophilic cells on mussel digestive gland tissue sections by means of toluidine-eosin staining.

J Invertebr Pathol 2019 Feb 4;161:29-39. Epub 2019 Jan 4.

CBET Research Group, Department of Zoology and Animal Cell Biology, Faculty of Science and Technology (ZTF/FCT) & Research Centre of Experimental Marine Biology and Biotechnology (Plentzia Marine Station; PiE-UPV/EHU), University of the Basque Country, Bilbo 48080, Basque Country, Spain. 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.

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

Immunological response to bacterial infection in a pelagic tunicate: Inflammation in the salp Thalia democratica.

J Invertebr Pathol 2018 Nov 22;159:28-40. Epub 2018 Oct 22.

Department of Biology and Evolution of Marine Organisms, Stazione Zoologica Anton Dohrn, Naples, Italy.

Thaliaceans are pelagic tunicates that play a key role in trophic chains of the oceans. In the field of tunicate immunity, a notable gap is the lack of data on their inflammatory response. The common salp, Thalia democratica, possesses scant immunocytes, represented by a phagocytic line (hyaline amebocytes) and a mast cell-like line (granular cells). Read More

Microsporidia (Opisthosporidia, Microsporidia) are frequent parasites of planktonic cladocerans, including Daphnia (Crustacea, Branchiopoda). Analysis of available molecular data (ITS region and partial ssu and lsu rDNA) of these parasites indicates that many microsporidia infecting daphnids have a common ancestor and represent a large clade, which splits during evolution into a number of well supported subclades. These subclades are cytologically different but may be most conveniently characterised by their specific ITS barcode. Read More

Synergistic effects of pathogen and pesticide exposure on honey bee (Apis mellifera) survival and immunity.

J Invertebr Pathol 2018 Nov 6;159:78-86. Epub 2018 Oct 6.

ARC Centre of Excellence in Plant Energy Biology, School of Molecular Sciences, The University of Western Australia, 6009 Crawley, Australia; Centre for Integrative Bee Research (CIBER), Department of Entomology, University of California, Riverside, CA 92521, United States. Electronic address:

Declines in native insect pollinator populations and substantial losses in managed honey bees have been reported on a global scale and become a widespread concern because of the importance of these insects for human food production and ecosystem stability. Several potential factors have been studied as possible causes of declining pollinator health, such as parasites and pathogens, exposure to agricultural pesticides, habitat loss and/or climate change. More recently, a combination of these factors rather than a single cause have been blamed for observed pollinator losses, but field studies of such interactions are challenging, especially in the presence of confounding environmental stressors.

Influence of the symbiont Wolbachia on life history traits of the cabbage root fly (Delia radicum).

J Invertebr Pathol 2018 Oct 5;158:24-31. Epub 2018 Sep 5.

INRA - UMR 1349 IGEPP (Institut de Génétique, Environnement et Protection des Plantes), Université de Rennes 1, 35042 Rennes Cedex, France.

Wolbachia is an endocellular bacteria infecting arthropods and nematodes and is only transmitted vertically by females via the cytoplasm of the egg. It is often a manipulator of host reproduction, causing cytoplasmic incompatibility, thelytokous parthenogenesis, feminization or male killing, which all increase the proportion of infected females in the population. However, Wolbachia can modify life history traits of the host without causing the above phenotypes and each species illustrates the variability of relationships between this remarkably versatile symbiont and its many hosts.

Jasmonic acid-induced plant defenses delay caterpillar developmental resistance to a baculovirus: Slow-growth, high-mortality hypothesis in plant-insect-pathogen interactions.

J Invertebr Pathol 2018 Oct 3;158:16-23. Epub 2018 Sep 3.

Department of Entomology and Center for Chemical Ecology, Pennsylvania State University, University Park, PA 16802, USA.

Plants damaged by herbivore feeding can induce defensive responses that reduce herbivore growth. The slow-growth, high-mortality hypothesis postulates that these non-lethal plant defenses prolong the herbivore's period of susceptibility to natural enemies, such as predators and parasitoids. While many juvenile animals increase their disease resistance as they grow, direct tests of the slow-growth, high-mortality hypothesis in the context of plant-herbivore-pathogen interactions are lacking.
