BACKGROUND Crops are often prone to both insect herbivory and disease, which necessitate multiple control measures. Ideally, an efficacious biological agent must adequately the target organism not be inhibited by other agents when applied simultaneously. Wheat seeds infected with plant pathogen Fusarium culmorum were treated Metarhizium brunneum or M. flavoviride Clonostachys rosea individually in combination, expectation root-feeding insects pathogen. Emerging roots evaluated for disease...
The genetic relationships and conidial tolerances to high low temperatures were determined for isolates of several Metarhizium species varieties.Molecular-based techniques [AFLP rDNA (ITS1, ITS2 5.8S) gene sequencing] used characterize morphologically identified spp. from a wide range sources. Conidial suspensions exposed wet heat (45 + or - 0.2 degrees C) plated on potato dextrose agar plus yeast extract (PDAY) medium. After 8-h exposure, the divided clearly into two groups: (i) all...
Knowledge of the natural occurrence and community structure entomopathogenic fungi is important to understand their ecological role. Species genus Metarhizium are widespread in soils have recently been reported associate with plant roots, but species M. flavoviride has so far received little attention intra-specific diversity among isolate collections never assessed. In present study was found be abundant spp. isolates obtained from roots root-associated soil winter wheat, oilseed rape...
Abstract Africa accounts for a significant portion of the world’s sweetpotato production where it is widely grown as staple crop. In sub-Saharan (SSA), serves an important year-round source calories and nutrition, form income smallholder pre-commercial farmers, increasingly used silage animal feed. However, yield per hectare considerably lower in SSA than from other regions primarily due to weevils (SPW, Cylas spp., Coleoptera: Brentidae). Weevil feeding causes physical damage root can...
Abstract The Mormon cricket (MC), Anabrus simplex Haldeman, 1852 (Orthoptera: Tettigoniidae), has a long and negative history with agriculture in Utah other western states of the USA. Most A. populations migrate large groups, their feeding can cause significant damage to forage plants cultivated crops. Chemical pesticides are often applied, but some settings (e.g. habitats threatened endangered species) call for non-chemical control measures. Studies Africa, South America, Australia have...
Farmers grow sweetpotatoes worldwide and some sub-Saharan African Asian diets include sweetpotato as a staple, yet the microbiome is conspicuously less studied relative to crops such maize, soybean, wheat. Studying ecology may reveal paths engineer improve yield, and/or combat pests diseases. We sampled surrounding soil from two North Carolina farms. took samples fields under different land management regimes, conventional organic, collected cultivars, ‘Beauregard’ ‘Covington’. By comparing...
Many insects are important agricultural pests, and active control is necessary to keep them at abeyance. The naturally occurring entomopathogenic fungus Metarhizium a promising tool pest insects, its use avoids the well-known harmful side effects of chemical pesticides. Thousands unique isolates exist throughout world. These vary widely in their ability cause infection tolerate stressful habitats. research reported here tests THESIS: A laboratory-based system can be devised that identifies,...
