Pathogenicity and sub-lethal activity of orally administered entomopathogenic fungi against two adult mosquito species, Aedes aegypti (Diptera: Culicidae) and Anopheles stephensi (Diptera: Culicidae).

Entomopathogenic fungi (EPF) are known for their efficacy in controlling adult mosquito populations by penetrating through their cuticle. However, the effect of oral administration of EPF on the biological parameters of Aedes aegypti and Anopheles stephensi remains largely unexplored. This study aimed to assess the effect of orally administrated EPF isolates on the survival, feeding behavior, fecundity, fertility, follicle development and host-searching behavior in response to yeast-generated CO of Ae.

A Model Nutrition Control System in Potato Tissue Culture and Its Influence on Plant Elemental Composition.

Low or excessive soil fertility is a major constraint to potato production. The influence of each individual nutrient element on potato plants under field studies remains ambiguous due to the influence of environmental variations. Creating an in vitro model plant with deficient or excessive nutrient content will provide a more controlled study and allow for a better understanding of how the concentration of one element can affect the uptake of other elements.

Optimization of an isothermal recombinase polymerase amplification method for real-time detection of Potato virus Y O and N types in potato.

Potato virus Y (PVY) is a global challenge for potato production and the leading cause of seed crop downgrading and rejection for certification. Accurate and timely diagnosis is key to effective control of PVY. Here we optimized the isothermal recombinase polymerase amplification (RPA) for accurate detection of different PVY O and N types that were tested, present in different tissues of potato plants including tubers with a primer set that specifically targets the highly conserved pipo region within the viral genome.

Proboscis infection route of Beauveria bassiana triggers early death of Anopheles mosquito.

Entomopathogenic fungi are known to control vector mosquito populations. Thus, understanding the infection dynamics of entomopathogenic fungi is crucial for the effective control of insect pests such as mosquitoes. We investigated the dynamics of Beauveria bassiana s.

Potential of Lecanicillium spp. for management of insects, nematodes and plant diseases.

Fungi in the genus Lecanicillium (formerly classified as the single species Verticillium lecanii) are important pathogens of insects and some have been developed as commercial biopesticides. Some isolates are also active against phytoparasitic nematodes or fungi. Lecanicillium spp.

Effects of fungal culture filtrates of Verticillium lecanii (Lecanicillium spp.) hybrid strains on Heterodera glycines eggs and juveniles.

Many nematode-antagonistic fungi produce secondary metabolites and enzymes that demonstrate toxicity against plant-parasitic nematodes. The objective of this study was to evaluate the effects of fungal culture filtrates of Verticillium lecanii hybrid strains on mature eggs, embryonated eggs (eggs fertilized but without development of juveniles), and second-stage juveniles (J2) of Heterodera glycines and to compare these effects with those of their parental strains. The fungal culture filtrates of certain hybrid strains inhibited egg hatch of mature eggs.
