Changes in haemolymph parameters and insect ability to respond to immune challenge during overwintering

with Žádné komentáře

Abstract: Overwintering is a challenging period in the life of temperate insects. A limited energy budget characteristic of this period can result in reduced investment in immune system. Here, we investigated selected physiological and immunological parameters in laboratory-reared and field-collected … Read More

Winter honeybee (Apis mellifera) populations show greater potential to induce immune responses than summer populations after immune stimuli

with Žádné komentáře

Abstract: In the temperate climates of central Europe and North America, two distinct honeybee (Apis mellifera) populations are found in colonies: short-living summer bees emerge in spring and survive until summer, whereas long-living winter bees emerge in late August and … Read More

Vigour-related traits and immunity in hybrids of evolutionary divergent cyprinoid species: advantages of hybrid heterosis?

with Žádné komentáře

Abstract Hybrid advantage, described as the superiority of hybrids in some traits over their parents and termed the “heterosis effect,” is widely documented in the case of reciprocal crosses of parental species (i.e., hybrids representing the F1 generation). In fish, … Read More

Differences in the growth rate and immune strategies of farmed and wild mallard populations

with Žádné komentáře

Individuals reared in captivity are exposed to distinct selection pressures and evolutionary processes causing genetic and phenotypic divergence from wild populations. Consequently, restocking with farmed individuals may represent a considerable risk for the fitness of free-living populations. Supportive breeding on … Read More

Heptabladed β‐propeller lectins PLL2 and PHL from Photorhabdus spp. recognize O‐methylated sugars and influence the host immune system

with Žádné komentáře

O‐methylation is an unusual sugar modification with a function that is not fully understood. Given its occurrence and recognition by lectins involved in the immune response, methylated sugars were proposed to represent a conserved pathogen‐associated molecular pattern. We describe the … Read More

Bioactive Excreted/Secreted Products of Entomopathogenic Nematode Heterorhabditis bacteriophora Inhibit the Phenoloxidase Activity during the Infection

with Žádné komentáře

Insects 2020, 11(6), 353; https://doi.org/10.3390/insects11060353 ABSTRACT: Entomopathogenic nematodes (EPNs) are efficient insect parasites, that are known for their mutualistic relationship with entomopathogenic bacteria and their use in biocontrol. EPNs produce bioactive molecules referred to as excreted/secreted products (ESPs), which have … Read More
