Robust manipulation of the behavior of Drosophila melanogaster by a fungal pathogen in the laboratory

eLife, 2018
Many microbes induce striking behavioral changes in their animal hosts, but how they achieve this is poorly understood, especially at the molecular level.

Adipokinetic Hormones Enhance the Efficacy of the Entomopathogenic Fungus Isaria fumosorosea in Model and Pest Insects

Pathogens, 2020
Insect adipokinetic hormones (AKHs) are neuropeptides with a wide range of actions, including the control of insect energy metabolism. These hormones are also known to be involved in the insect defence system against toxins and pathogens.

Effect of photoperiod and host distribution on the horizontal transmission of Isaria fumosorosea (Hypocreales: Cordycipitaceae) in greenhouse whitefly assessed using a novel model bioassay [PDF]

, 2010
A model bioassay was used to evaluate the epizootic potential and determine the horizontal transmission efficiency of Isaria fumosorosea Trinidadian strains against Trialeurodes vaporariorum pharate adults under optimum conditions (25±0.5°C, ~100% RH ...

Temperature restriction in entomopathogenic bacteria [PDF]

Frontiers in Microbiology, 2020
AbstractTemperature plays an important role in bacteria-host interactions and can be a determining factor for host switching. In this study we sought to investigate the reasons behind growth temperature restriction in the entomopathogenic enterobacteriumPhotorhabdus. Photorhabdushas a complex dual symbiotic and pathogenic life cycle. The genus consists

Relationship between chemical properties of the soil and the occurrence of Bacillus thuringiensis Relação entre as características químicas do solo e a ocorrência de Bacillus thuringiensis

Ciência Rural, 2009
The soil and other substrates such as mushroom compounds are the main sources of new Bacillus thuringiensis (Bt) isolates for Integrated Pest Management programs. This study describes the relationship between chemical properties of the soil (pH, OM, P3+,

No evidence for social immunity in co-founding queen associations. [PDF]

, 2017
Ant queens often associate to found new colonies, yet the benefits of this behaviour remain unclear. A major hypothesis is that queens founding in groups are protected by social immunity and can better resist disease than solitary queens, due to mutual ...

Identification of a Penicillium oxalicum fungus isolate and its pathogenicity against Panonychus citri (McGregor)

Frontiers in Microbiology
To obtain efficient biocontrol fungi against Panonychus citri, this study systematically identified the highly pathogenic strain HYC2101 through an analysis of its cultural characteristics, physiological and biochemical properties, and molecular ...

Sanitation felling against the European spruce bark beetle: A matter of intensity and forest type Tagli fitosanitari contro il bostrico tipografo: una questione di intensità e tipologia forestale

Agricultural and Forest Entomology, EarlyView.
We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

Pathogenicity and horizontal transmission of Beauveria bassiana and Metarhizium anisopliae isolates used against Sahlbergella singularis, ccoa pest in Cameroon [PDF]

, 2017
The brown cocoa mirid, Sahlbergella singularis (Heteroptera: Miridae) has been named the most economically important insect pest of cocoa across West African and it is capable to cause yield loss of about 30 to 70%.
