Development of a new method for collecting hemolymph and measuring phenoloxidase activity in Tribolium castaneum

BMC Research Notes, 2019
Objective Hemolymph plays many important roles in the physiology of an insect throughout its lifetime; however, for small-bodied insects, studies are lacking because of the difficulties encountered while collecting hemolymph.

Cytotoxic and Immunological Effects of Terpinolene and 1-butyl-3,4-methylenedioxybenzene on Aedes aegypti Larvae. [PDF]

Arch Insect Biochem Physiol
The terpinolene + BMDB association caused severe midgut damage, increased apoptosis, reduced proliferation, and immune suppression in Ae. aegypti larvae, indicating that sublethal effects, despite higher LC50, compromise larval recovery and represent a promising strategy for integrated vector management.

Cellular immune response of Amblyomma sculptum and Amblyomma americanum to entomopathogenic fungi: Implications for biological tick control. [PDF]

Med Vet Entomol
Amblyomma sculptum showed a plasmatocyte‐dominant haemocyte profile. Beauveria bassiana increased plasmatocytes and reduced granulocytes, whereas Metarhizium robertsii did not cause significant changes. Amblyomma americanum showed a granulocyte‐dominant haemocyte profile. Beauveria bassiana reduced total haemocytes and granulocytes. B.

The Relative Contributions of BmPPO and BmDDC in Immune Melanization of Hemolymph in Silkworm, Bombyx mori [PDF]

Insects
Lepidoptera constitute a major group of agricultural and forestry pests. Therefore, investigating the immune mechanisms of the model species Bombyx mori may provide valuable insights for the development of improved pest management strategies. In insects,

Effect of Honey and Syrup Diets Enriched with 1,3-1,6 β-Glucans on Honeybee Survival Rate and Phenoloxidase Activity (Apis mellifera L. 1758)

Veterinary Sciences, 2021
β-glucans can activate the animal innate immune system by acting as immune-modulators and inducing various stimulatory effects. The aim of this study was to investigate the effect of 1,3-1,6 β-glucans administered orally for 96 h on Apis mellifera ...

CLIPB4 Is a Central Node in the Protease Network that Regulates Humoral Immunity in Anopheles gambiae Mosquitoes

Journal of Innate Immunity, 2023
Insect humoral immune responses are regulated in part by protease cascades, whose components circulate as zymogens in the hemolymph. In mosquitoes, these cascades consist of clip-domain serine proteases (cSPs) and/or their non-catalytic homologs, which ...

A High Soldier Proportion Encouraged the Greater Antifungal Immunity in a Subterranean Termite

Frontiers in Physiology, 2022
Termites possess a mighty social immune system, serving as one of the key obstacles to controlling them biologically. However, the dynamic mechanism coordinating the social immunologic defense and caste distribution of the termites remains elusive.

Beneficial Bacteria in the Intestines of Housefly Larvae Promote Larval Development and Humoral Phenoloxidase Activity, While Harmful Bacteria do the Opposite

Frontiers in Immunology, 2022
The gut microenvironment of houseflies provides unique conditions for microbial colonization. Some gut microorganisms provide benefits for the development of the host by regulating the interaction between the host and intestinal pathogens.

Early Virulence Predictors during the Candida Species–Galleria mellonella Interaction

Journal of Fungi, 2020
Fungal infections are a serious and increasing threat for human health, and one of the most frequent etiological agents for systemic mycoses is Candida spp.
