Lack of phenotypic and evolutionary cross-resistance against parasitoids and pathogens in Drosophila melanogaster [PDF]
, 2012 BackgroundWhen organisms are attacked by multiple natural enemies, the evolution of a resistance mechanism to one natural enemy will be influenced by the degree of cross-resistance to another natural enemy.

Myriapod haemocyanin: the first three-dimensional reconstruction of Scolopendra subspinipes and preliminary structural analysis of S. viridicornis [PDF]
Open Biology, 2020 Haemocyanins (Hcs) are copper-containing, respiratory proteins that occur in the haemolymph of many arthropod species. Here, we report the presence of Hcs in the chilopode Myriapoda, demonstrating that these proteins are more widespread among the ...

Recent findings on phenoloxidases in bivalves [PDF]
Marine Pollution Bulletin, 2017 The production of melanin is a complex process involving biochemical cascades, such as the pro-phenoloxidase (proPO) system, and enzymes, such as phenoloxidases (POs). Different studies have shown a strong correlation between the decrease in PO activities and the occurrence of diseases in bivalve invertebrates, leading to mortalities in the host ...

Induced hyperlipaemia and immune challenge in locusts [PDF]
, 2004 Injections of immunogens, such as β-1,3-glucan or lipopolysaccharide (LPS), bring about a marked hyperlipaemia with associated changes in lipophorins and apolipophorin-III in the haemolymph of Locusta migratoria.

Immune defense of Pieris brassicae larvae in challenged with Heterorhabditis bacteriophora, its symbiotic bacteria and metabolites [PDF]
Invertebrate Survival Journal, 2017 In this study, virulence of the culture broth of Photorhabdus temperata subsp. temperata and its aqueous and organic extracts were investigated for 3rd and 4th instars of Pieris brassicae (Lepidoptera: Pieridae) larvae. Virulent efficacy was found in all
