Interactions Among Bt Maize, Entomopathogens, and Rootworm Species (Coleoptera: Chrysomelidae) in the Field: Effects on Survival, Yield, and Root Injury [PDF]

, 2013
A 2 yr field study was conducted to determine how a blend of entomopathogens interacted with Bt maize to affect mortality of Diabrotica spp. (Coleoptera: Chrysomelidae), root injury to maize (Zea maize L.) and yield. The blend of entomopathogens included

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+,

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

Insights into Adaptations to a Near- Obligate Nematode Endoparasitic Lifestyle from the Finished Genome of Drechmeria coniospora [PDF]

, 2016
Nematophagous fungi employ three distinct predatory strategies: nematode trapping, parasitism of females and eggs, and endoparasitism. While endoparasites play key roles in controlling nematode populations in nature, their application for integrated pest

Wood ants protect their brood with tree resin [PDF]

, 2014
Social insects use multiple lines of collective defences to combat pathogens. One example of a behav- ioural group defence is the use of antimicrobial plant compounds to disinfect the nest.

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo

Pest Management Science, EarlyView.
The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

Neutrosophic Analysis in the Evaluation of the Use of Beauveria Bassiana against the Potato Grub [PDF]

Neutrosophic Sets and Systems
Beauveria bassiana is an entomopathogenic fungus that has been shown to have the potential to control the potato white grub (Premnotrypes vorax), a pest that significantly affects potato production, especially in Ecuador. Therefore, the present study has
