A wide range of insects affect crop production and cause considerable yield losses. Difficulties reside on the development adaptation adequate strategies to predict insect pests for their timely management ensure enhanced agricultural production. Several conceptual modelling frameworks have been proposed, choice an approach depends largely objective model availability data. This paper presents a summary decades advances in population dynamics, phenology models, distribution risk mapping....
Black soldier fly frass fertilizer (BSFFF) is increasingly gaining momentum worldwide as organic fertilizer. However, research on its performance crop production remains largely unknown. Here, we evaluate the comparative of BSFFF and commercial (SAFI) maize (H513) production. Both fertilizers were applied at rates 0, 2.5, 5 7.5 t ha-1, 30, 60 100 kg nitrogen (N) ha-1. Mineral (urea) was also N ha-1 to establish equivalence (NFE) fertilizers. Maize grown in plots treated with had tallest...
Abstract Maize is a major staple food for over 300 million people in sub‐Saharan Africa. Sustainable productivity of this primary crop has been recently threatened by Fall armyworm (FAW), Spodoptera frugiperda invasion. Due to lack environmentally safe management strategies, immediate responses growers and governments tackle FAW are based on rampant use pesticides. Looking efficient biopesticides, twenty entomopathogenic fungal isolates (14 Metarhizium anisopliae 6 Beauveria bassiana ) were...
