[PDF] Interaction between the entomopathogenic bacterium Bacillus thuringiensis subsp. kurstaki and two entomopathogenic fungi in bio-control of Sesamia nonagrioides (Lefebvre) (Lepidoptera: Noctuidae) | Semantic Scholar (2024)

Investigation of the entomopathogenic action of Beauveria bassiana and M. robertsii can protect sweet sorghum from damage induced by S. nonagrioides under natural environmental conditions without affecting plant physiology and growth.

The results show that some product combinations have potential additive or synergistic effects on bees, whereas others did not affect the bee’s survival compared to the control, and effects on bee mortality might originate in the treatment with the different microorganisms or their metabolites.

A novel pest management strategy underlying the cooperation between EPF infection and disturbing the insect immune system is discussed, and novel perspectives for EPF-mediated pest management and developing effective fungal insecticides are provided.

Results showed a clear dose-dependent pesticidal activity, expressed as significant adult mortality at a high-dose application, although some of the combinations of caffeic acid concentrations with the other substances acted positively (synergistically and additively) and some negatively.

The potential of Pl as a potent bioinsecticide to economically and sustainably control Pl. xylostella and other lepidopteran pests is highlighted.

This article addresses the literature on entomopathogenic fungi through the years, noting their mode of action, advantages, potential applications, and prospects.

In its individual application, CBD oil generated the highest insect mortality while its effect was clearly dose-dependent, revealing a promising effect of CBD oil against these coleopterans which had not been previously tested together.

Combining the calibrated sprayer and bioassay method provides a reliable, standardised approach to test the virulence of EPF against whitefly nymphs.

Good correlation was found between fumonisin contamination and the degree of insect damage by Sesamia of the tested hybrids, calculated on the basis of percentage of ears visibly damaged by insects and with more than 5% kernel loss.

Individuals that survived the B. bassiana and N. pyrausta treatments and developed into adults had significantly shorter lifespans and females oviposited fewer eggs than non-exposed insects and the effects on the longevity and the egg production were most pronounced at high concentration of B.bassiana conidia.

A model for predicting the occurrence of the critical photoperiod according to latitude and temperature and the spread of S. nonagrioides in the circum-Mediterranean countries is presented and Responses of populations to short-day length suggest that thespread of the species is associated with a gradual loss of diapause in the southern areas, and thatDiapause incidence is positively correlated with latitude.

The results have shown that the impact of T. absoluta can be greatly reduced by spraying only B. thuringiensis-based formulates, with no need for chemical insecticides, and the integration of this technology with other biological control methods focused on T. Absoluta eggs, such as the use of mirid predators or parasitoids.

A synchronous coinfection of the Colorado potato beetle with the entomopathogenic bacteria Bacillus thuringiensis ssp.

The phylogenetic and in some cases morphological evidence supports the monophyly of nine terminal taxa in the M. anisopliae complex, and it is proposed to recognize at species rank M. guizhouense, M. pingshaense and M. robertsii.

Sweet sorghum (Sorghum bicolor (L.) Moench) was introduced recently into Greece and is being cultivated experimentally for the production of liquid biofuel, where a significant negative correlation was found between the body length of S. nonagrioides larvae and the internode from which they were retrieved.
