“…We speculated that the difference in above enzymes activities changes was induced by the difference in secretions between IMI330189 and IBC200614 because that the difference in above enzymes activities changes was mainly found in infection process and M . anisopliae could initiate difference variation in SOD, CAT and POD in difference insect [ 52 , 53 ].

“…In Periplaneta Americana , M . anisopliae , Isaria fumosoroseus and Hirsutella thompsonaii fungal infections initiate oxidative stress in the midgut, fat body, whole body and hemolymph, and decrease the CAT activity of fat body and midgut [ 52 ]. In Spodoptera litura , the activities of SOD, CAT, POD and specific ascorbate peroxidase in the larval body decreased after it was treated with crude destruxins at the doses that caused 90% mortality[ 53 ].Thus, the clarification of the roles of these enzymes in the immune response of insects to fungi is important for the efficient use of entomopathogenic fungi as biocontrol agents.…”

BackgroundMetarhizium is an important class of entomopathogenic fungi in the biocontrol of insects, but its virulence is affected by insect immunity. To clarify the mechanism in virulence of Metarhizium, we compared the immunological differences in Locusta migratoria L. when exposed to two strains of Metarhizium anisopliae (Ma).ResultsThe virulence of Ma IMI330189 was significantly higher than that of Ma IBC200614 to locust, and IMI330189 overcame the hemocytes and began destroying the hemocytes of locust at 72 h after spray, while locust is immune to IBC200614. IMI330189 could overcome the humoral immunity of locust by inhibiting the activities of phenol oxidase (PO), esterases, multi-function oxidases (MFOs) and acetylcholinesterases in locust while increasing the activities of glutathione-S-transferases (GSTs), catalase and aryl-acylamidase (AA). However IBC200614 inhibit the activities of GSTs and AA in locust and increase the activities of MFOs, PO, superoxide dismutase, peroxidase and chitinase in locust. The changes of enzymes activities in period of infection showed that the time period between the 2nd and the 5th day after spray is critical in the pathogenic process.ConclusionThese results found the phenomenon that Ma initiatively broke host hemocytes, revealed the correlation between the virulence of Ma and the changes of enzymes activities in host induced by Ma, and clarified the critical period in the infection of Ma. So, these results should provide guidance for the construction of efficient biocontrol Ma strains.

“…Lipid peroxidation and its products, such as malondialdehyde, have been observed in insects after exposure to entomopathogenic fungi. Chaurasia et al(2016) [60] report an increase in MDA level in the fat bodies and gut of Periplaneta americana after exposure to M. anisoploae, Isaria fumosoroseus and Hirsutella thompsonaii, while its level decreased in the hemolymph and the rest of the body. Similar results were obtained by [61], who note a lower level of MDA in cockroaches injected with M. anisopliae spores.…”

Conidiobolus coronatus induces oxidative stress and autophagy response in Galleria mellonella larvae

et al. 2020

Cell homeostasis requires the correct levels of reactive oxygen species (ROS) to be maintained as these regulate the proliferation and differentiation of cells, and control the immune response and inflammation. High levels of ROS can cause oxidative stress, leading to protein, lipid and DNA damage, or even cell death. Under physiological conditions, the rate of autophagy remains stable; however, it can be accelerated by a number of exogenous stimuli such as oxidative stress, starvation or hypoxia, leading to cell death. The present paper examines the effect of Conidiobolus coronatus infection on the immune response, oxidative stress processes and autophagy in the greater wax moth, Galleria mellonella. Fungal infection was found to result in the disorganization of the cytoskeleton of the larval immune cells and the enhancement of oxidative defense processes. Lipid peroxidation and autophagy were also induced in the hemocytes. Our findings show that G. mellonella is an ideal model for exploring immune mechanisms.

“…Pathogens used to control insects include bacteria, viruses, and fungi, which are usually host-specific (Vega & Kaya 2012). Thousands of strains of entomopathogenic fungi have been isolated, from species in more than 50 genera (Khan et al 2012;Hussain et al 2014); however, the use of fungi-based bioinsecticides for management remains uncommon (Chaurasia et al 2016). The success of a mycoinsecticide depends on several criteria, but the 1st is its virulence level (Hussain et al 2014).…”
