Differentiation of the entomopathogenic fungus Metarhizium flavoviride (Hyphomycetes) [PDF]

Revista de Microbiologia, 1999
The differentiation of a Brazilian isolate of Metarhizium flavoviride (CG 423), a promising candidate for the biocontrol of grasshoppers, was investigated. Conidia were spread onto solid medium (1% yeast extract, 2.8% agar, 96.2% distilled water), incubated at 28°C and observed during 26 h. Germination initiated as conidia size increased from 5.3 (±0.6)

Evaluation of KO-Tab 1-2-3: a wash-resistant 'dip-it-yourself' insecticide formulation for long-lasting treatment of mosquito nets. [PDF]

, 2005
INTRODUCTION: Insecticide-treated nets (ITN) are an important method of preventing malaria. To remain effective, they need to be re-treated with pyrethroid insecticide at approximately yearly intervals. Systems for re-treating nets in Africa are limited,

The occurrence of entomopathogenic fungi in soils from mid-field woodlots and adjacent small-scale arable fields

Acta Mycologica, 2013
The aim of this study was to compare the species composition and the intensity of entomopathogenic fungi occurrence in the soil from mid-field woodlots and adjacent small farmlands.

Effects of an entomopathogenic fungus on the reproductive potential of Drosophila males. [PDF]

Ecol Evol
AbstractWhile mortality is often the primary focus of pathogen virulence, non‐lethal consequences, particularly for male reproductive fitness, are less understood; however, they are essential for understanding how sexual selection contributes to promoting resistance.

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

Insect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

Status of pyrethroid resistance in Anopheles gambiae s. s. M form prior to the scaling up of Long Lasting Insecticidal Nets (LLINs) in Adzopé, Eastern Côte d'Ivoire. [PDF]

, 2012
BACKGROUND: The growing development of pyrethroid resistance constitutes a serious threat to malaria control programmes and if measures are not taken in time, resistance may compromise control efforts in the foreseeable future.

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

Journal of Applied Entomology, EarlyView.
ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...

Multiple insecticide resistance mechanisms in Anopheles gambiae and Culex quinquefasciatus from Benin, West Africa. [PDF]

, 2007
Because free-insecticide treated net distribution is planned in Benin (West Africa) during the next few years, we investigated the type, frequency and distribution of insecticide resistance mechanisms in Anopheles gambiae and Culex quinquefasciatus ...

Bioprospection of Tenellins Produced by the Entomopathogenic Fungus Beauveria neobassiana. [PDF]

J Fungi (Basel)
Fungi are known as prolific producers of bioactive secondary metabolites with applications across various fields, including infectious diseases, as well as in biological control. However, some of the well-known species are still underexplored. Our current study evaluated the production of secondary metabolites by the entomopathogenic fungus Beauveria ...

Cellular immune response of Amblyomma sculptum and Amblyomma americanum to entomopathogenic fungi: Implications for biological tick control

Medical and Veterinary Entomology, EarlyView.
Amblyomma sculptum showed a plasmatocyte‐dominant haemocyte profile. Beauveria bassiana increased plasmatocytes and reduced granulocytes, whereas Metarhizium robertsii did not cause significant changes. Amblyomma americanum showed a granulocyte‐dominant haemocyte profile. Beauveria bassiana reduced total haemocytes and granulocytes. B.
