Mosquitoes transmit pathogens that cause human diseases such as malaria, Dengue fever, Chikungunya, yellow Zika and filariasis. Chemical pesticides are effective instruments for reducing disease transmission managing mosquito populations. However, these chemicals have drawbacks high production costs negative effects on the environment non-target organisms. Furthermore, mosquitoes develop resistance to chemical insecticides, they become less effective. As a result, researchers investigating novel insecticides. Advances in microbial biotechnology resulted wide range of value-added products, including biopesticides agricultural public health purposes. In this review, we highlight mainly untapped biotechnological potential microorganisms vector control reduction. Also, underline importance more basic research improved translational methodologies, encouraging efforts bridge gap between academic interventions.

Fungal diseases are widespread among insects and play a crucial role in naturally regulating insect populations. Mosquitoes, known as vectors for numerous infectious diseases, pose significant threat to human health. Entomopathogenic fungi (EPF) have emerged highly promising alternative agents chemical mosquitocides controlling mosquitoes at all stages of their life cycle due unique infection pathway through direct contact with the insect’s cuticle. In recent years, advancements been made understanding pathways pathogenic mechanisms EPF against mosquitoes. Various strategies involving use alone or combinations other approaches employed target various developmental stages. Moreover, application genetic technologies has opened up new avenues enhancing mosquitocidal efficacy EPF. This review presents comprehensive summary our EPF, applications mosquito management, combination employment transgenic technologies. The biosafety concerns associated corresponding also discussed. progress suggests that potential serve future biorational tool vectors.

Certain entomopathogenic fungi, such as Beauveria bassiana, are highly pathogenic to arthropod pests and able colonize plant tissues, thereby enhancing both growth disease resistance. This study assessed three B. bassiana strains (CBM1, CBM2, CBM3) for their pathogenicity toward insect larvae colonization potential in wheat. The insecticidal activity of the fungi against major lepidopteran Helicoverpa armigera, Spodoptera frugiperda, Mythimna separata, Plutella xylostella was determined. were then applied wheat plants using seed immersion soil drench methods; rates compared, impacts fungal on survival evaluated. results demonstrated that all effective reducing damage, with CBM1 exhibiting highest followed by CBM3 CBM2. particularly effective, a significantly higher rate achieved through drenching compared immersion. inoculation resulted increased height at 30 days after sowing (DAS) root length 15 DAS control group.

Rhipicephalus microplus is a persistent ectoparasite of cattle that causes bovine anaplasmosis and babesiosis, causing economic losses worldwide. Chemical treatment the primary method for tick control, but emergence pesticide-resistant ticks major challenge. Alternative biocontrol strategies utilizing entomopathogenic microorganisms are being explored. This study aimed to validate species identification assess efficacy four strains Staphylococcus bacteria (S. shinii S1 S-2, S. succinus, xylosus) previously reported as R. ticks. According bioassays, S-1 exhibited greatest degree reproductive inhibition (47%), followed by succinus (44.3%) at concentration 1 × 108 cfu/mL. xylosus displayed decreased (6.3%). In an additional bioassay, significant larval mortality 67.63%, with 66.75%, shinni S-2 64.61%, 28.18% mortality. The common signs infection observed on these included swelling, yellowish exudate hypostome, reduced limb mobility color change, except which did not cause changes. These were naturally found skin. However, further studies needed confirm their potential promising alternatives or complementary agents existing acaricidal compounds.

Though the entomopathogenic fungus Beauveria bassiana has shown to be efficacious for managing Dermanyssus gallinae infestations, its delivery as liquid formulation poses concerns related environmental stability and efficacy. To overcome such concerns, here we proposed a hydrogel matrix based on hydroxyethyl-cellulose (HEC) delivering B. control D. gallinae. Nymph adult mites were exposed or filter papers containing (107 conidia/mL), with without pre-incubation period of 4 days at 25 °C (treated groups). As groups, sterile distilled water. Results showed higher mortality all stages in treated groups compared respective groups. The LT50 LT90 estimated lower (LT50 ≤ 9.5 adults; 10.7 nymphs; 14.9 17.9 nymphs) than (LT5 0 ≥14.9 adults, > 19 20 adults nymphs). Pre-incubation significantly reduced respect other Overall, our study outlined that conidial suspension is against both nymphs HEC enhanced Thus, through HEC-based may represent an effective sustainable solution infestations poultry industry.
