Insects constitute approximately 75% of the world’s recognized fauna, with majority species considered as pests. Entomopathogenic fungi (EPF) are parasitic microorganisms capable efficiently infecting insects, rendering them potent biopesticides. In response to infections, insects have evolved diverse defense mechanisms, prompting EPF develop a variety strategies overcome or circumvent host defenses. While interaction mechanisms between and is well established, recent findings underscore that their interplay more intricate than previously thought, especially evident across different stages infection. This review primarily focuses on insect strategies, centered around three infection stages: (1) Early stage: involving pre-contact detection avoidance behavior in along induction behavioral responses upon contact cuticle; (2) Penetration intra-hemolymph growth initiation cellular humoral immune functions while symbiotic microbes can further contribute resistance; (3) Host insect’s death ultimate confrontation pathogens insects. Infected strive separate themselves from healthy population, rely infected spread new hosts. Also, we discuss novel pest management strategy underlying cooperation disturbing system. By enhancing our understanding insect, this provides perspectives for EPF-mediated developing effective fungal insecticides.

Abstract Mosquitoes around the world spread diseases like malaria, dengue, zika, lymphatic filariasis and arboviruses, which are dangerous to human health economy. Eventually, mosquitoes develop resistance synthetic chemical insecticides and, moreover, these have adverse environmental impacts, accumulating in soils food chain. So, researchers searching for better vector control tools from biological sources such as plants, bacteria, fungi, viruses other predators. Eco‐friendly methods that use entomopathogenic fungi reduce vector‐borne disease burdens becoming more popular because they selective safe environment. Based on existing literature, several microbial agents show potential biocontrol of mosquitoes. With advances genetic recombination transformation techniques, ongoing battle against insecticide‐resistant mosquitoes, genetically engineered fungal biopesticides represent a cutting‐edge solution. These result novel changes improve ability target kill can effectively combat mosquito populations by introducing genes produce insecticidal proteins or toxins. This method has advantages, including lower impact, highly specific harmless non‐target organisms. It also helps problem insecticide unique mode action. hold great promise reducing mosquito‐borne while minimizing damage combating resistance. review article discusses various pathogens act their action We discus recent fungi‐secreted effector molecules suppressing host immunity progress development transgenic mosquito‐killing fungi.

Abstract Insect pests of agricultural crops have establish immunological tolerance against fungal infection caused by pathogens via different humoral and cellular processes. Fungal can be prevented insect antioxidant detoxifying enzymes, but there is no clear understanding how they physiologically biochemically interact. Our study aims to examine the enzyme defense systems pest Spodoptera litura in response Metarhizium flavoviride . At 48 h following exposure M. , levels were modified, phenoloxidase total hemocyte count decreased significantly. The amount enzymes increased appears directly affect S. immune system results immunity. In a bioassay, was found harmful larvae their third fourth instar stage. may an effective tool control larvae. Such entomopathogenic fungi represent cheaper, pollution free, target specific, promising alternatives synthetic chemical tools for pests.

Abstract Ant-infecting Ophiocordyceps fungi are globally distributed, host manipulating, specialist parasites that drive aberrant behaviors in infected ants, at a lethal cost to the host. An apparent increase activity and wandering precedes final summiting biting behavior onto vegetation, which positions manipulated ant site beneficial for fungal growth transmission.

Abstract Biocontrol with hypocrealean entomopathogenic fungi (EF) is a key tool to develop Integrated Pest Management (IPM) programs for the progressive replacement of synthetic chemical insecticides more environmentally friendly pest control measures. These stand out among entomopathogens not only their contact mechanism infection through arthropod integument, but also developing close associations plants including endophytic lifestyle and rhizosphere competence that can enable them make broader contributions IPM crop production. Anyhow, interaction EF incorporates multitrophic complexity at different levels insect pests, plants, natural enemies. The aim present review was gather summarize all available data on interactions EF. influence both ecology host-plant selection by pests host or prey parasitoid predators, respectively. Moreover, treatments are compatible enemies in terms safety effectiveness, which could allow biocontrol strategies synergistic application programs.

Exploring the pathogenicity of a new fungus strain to non-target host pests can provide essential information on large scale for potential application in pest control. In this study, we tested Beauveria bassiana PfBb important agricultural Spodoptera frugiperda (Lepidoptera: Noctuidae) by determining relative activities protective enzymes and detoxifying different larval instars. Our results show that B. could infect all six instars S. frugiperda, its virulence larvae gradually increased with an increase spore concentration. Seven days after inoculation, LC50 was 7.7 × 105, 5.5 106, 2.2 107, 3.1 108, 9.6 2.5 1011 spores/mL first sixth respectively, LC90 each instar decreased infection time, indicating significant dose effect. Furthermore, instar. The (i.e., catalase, peroxidase, superoxide dismutase) glutathione S-transferases, carboxylesterase, cytochrome P450) three infected changed significantly but such variations were not obvious fifth Additionally, being PfBb, detoxification usually lasted from 12 48 h, which longer than These indicate depended stage. Therefore, findings study suggest be used as bio-insecticide control young integrated management program.
