Food losses, defined as a reduction in the quantity and quality of food during production storage, impact safety security. Losses caused by plant pathogens are among most significant. Chemical pesticides have been extensively used to prevent microbial diseases. Their toxicity reduced efficacy, however, encouraged investigators develop alternatives. Alternatives based on biopesticides tend be sa...

We evaluated the larvicidal activity of the granular formulation of Bacillus thuringiensis israelensis (Bti) serotype H-14 (Vectobac G, 200 ITU/mg) and Bacillus sphaericus (Bsph) serotype H5a5b (Vectolex CG, 670 Bs ITU/mg) against Anopheles arabiensis and other mosquitoes in breeding habitats in 3 sites, Gash-Barka, Anseba, and Debub zones, in Eritrea. The primary objective was to determine the...

Abstract The outbreak of the fall armyworm, Spodoptera frugiperda, in Africa has led to several recommendations insecticides, including biopesticides. However, effects these products on environment, especially parasitoids have not been assessed under field conditions. Here, we investigated effect commonly used biopesticides S. frugiperda management and larval northern Ghana. experiments were co...

Microbial products based on the entomopathogenic bacterium Bacillus thuringiensis (Bt) are among the most common biopesticides used worldwide to suppress insect pests in forests, horticulture and agricultural crops. Some of the effects of commercial Bt have been recorded for terrestrial and freshwater non-target organisms but little research is available on marine fauna. Nevertheless, due to th...

Recent research has indicated that fungal biopesticides could augment existing malaria vector control tools. Here we present a set of methodologies to monitor the in vivo kinetics of entomopathogenic fungi in Anopheles in the presence or absence of malaria parasites using quantitative real-time PCR. Three qPCR assays were successfully developed for counting fungal genomes: "specific" assays cap...

Biological control is an environmentally friendly approach that holds promise to complement or replace chemicals effectively protect crop plants against pests and pathogens. Environmental samples with highly diverse competitive microbiomes harbor antagonistic microbes modes-of-action can provide a rich source of microbial biopesticides. In the current study, bacteria isolated from rhizosphere s...

The use of biopesticides against agricultural pests is great importance for the sustainability pest management. goal present study was to determine lethal (acute) and sublethal (first male young queen emerge time, competition point, total number workers, males queens) effects four commercial [Nibortem (1.5% Lecanicillium (Verticillium) lecanii strain V1-1, Nostalgist Beauveria bassiana Bb-1), P...
