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....
Abstract Processing organic waste using black soldier fly (BSF)-based technology offers a promising alternative for sustainable management and urban sanitation. This study was conducted to assess the influence of feeding strategies on efficacy BSF larvae recycle wastes into value products. Fruit chicken manure were used as samples while commercial feed control, processed 15 days in circular plastic containers (Ø 30 × 12 cm) with 50; 100; 150; 200 mg/larva/day continuous batch diets, 500...
Performance and body composition of insect larvae depend on quality quantity their diet, biotic factors such as larval density. Experiments were undertaken to assess the effects density, substrate moisture content feedstock ratio life history parameters black soldier fly (BSF) in laboratory. Four-day-old separately reared under six different densities (1, 2, 4, 6, 8 10 larvae/cm 2 ) at five levels (40, 50, 60, 70 80%) obtained by moistening feed with fresh water. Five ratios 25, 100, 150 200...
Rhipicephalus decoloratus causes serious economic losses in cattle industry every year East Africa. Biological control using entomopathogenic fungi is seen as a promising alternative to chemical acaricides being used for their control. The pathogenicity of Metarhizium anisopliae and Beauveria bassiana isolates was tested the laboratory against amitraz-resistant amitraz-susceptible strains R. decoloratus. Unfed larvae were sprayed with conidial suspensions 1×10(9) conidia ml(-1). Fungal...
Cowpea, Vigna unguiculata ((L.) Walp; Fabales: Fabaceae), is an important indigenous vegetable and grain legume in the tropics where it represents a major diet component. Cowpea aphid, Aphis craccivora (Koch; Hemiptera: Aphididdae) pest causing up to 100% yield losses. Aiming at establishing alternative approach synthetic insecticides, we evaluated pathogenicity of 23 fungal isolates including Metarhizium anisopliae ((Metschn.) Sorokin; Hypocreales: Clavicipitaceae), Beauveria bassiana...
Valorisation of organic waste through larval feeding activity the Black Soldier Fly (BSF),Hermetia illucens, constitutes a potential benefit for low- and middle-income countries. BSF larvae feed on while building their body composition protein fat. As response to escalating demand in livestock feed, can be used replace fishmeal monogastric animals' diet. Experiments were carry out evaluate feasibility (BSF) Hermetia illucens Linnaeus digest degrade small-scale. Organic wastes (pig chicken...
Abstract Background This study investigates the potential of black soldier fly (BSF) larvae to recycle agricultural waste into larval biomass for chicken feed, and was carried out at University Dschang, Cameroon in 2020. Fruit consisting papaya, pineapple orange peels, cocoa pods from local sources were used this study. They first grinded, fruit subjected directly a pre-established BSF colony. Cocoa on other hand mixed with Tithonia leaves 0% (C100:T0), 5% (C95:T5), 10% (C90:T10), 15%...
Experiments were carried out to validate the use of F. glumosa extract as a diuretic in treatment hypertension claimed by traditional healers. The experiments performed under same conditions with two synthetic pharmacological diuretics considered check (Furosemide and Amiloride hydrochlorothiazide). aqueous leaves accelerated elimination overloaded fluid. At maximum response, urinary osmolarity decreased significantly when compared controls. single dose has increased urine volume 24 h after...
Ficus glumosa Del (Moraceae), a plant used in traditional medicine Cameroon, Senegal, and East Africa for the treatment of edema, hemorrhoid, cardiovascular diseases especially hypertension.The present study evaluated potential toxicity aqueous extract leaves F.glumosa acute sub-chronic administration rodents.Acute was on 3 months old mice both sexes weighing 20-30 g. A single dose (2-12 g/kg) F. administered orally to mice. Animal behavior, adverse effects, mortality were determined 14...
Abstract Leaf extracts of Capurnia aurea (Fabaceae) have been reported to attract ticks and can be considered for use in combination with entomopathogenic fungus an autodissemination approach, whereby that are attracted baited traps infected the inoculum. Bioassays were undertaken assess compatibility aqueous, methanol acetone C. conidia Metarhizium anisopliae sensu stricto (ss) (Hypocreales: Clavicipitaceae) isolate ICIPE 7 terms mycelial growth, conidial production spore viability.

Biological systems have the capacity to not only build and robustly maintain complex structures but also rapidly break up rebuild such structures. Here, using primitive societies of Polistes wasps, we show that both robust specialization rapid plasticity are emergent properties multi-scale dynamics. We combine theory with experiments that, after perturbing social structure by removing queen, correlate time-resolved multi-omics video recordings. queen-worker dimorphism relies on balance...
Acanthus montanus T. Anderson (Acanthaceae) possesses several medicinal properties; it is used in Cameroon as a folk medicine to treat pain, inflammation and threatened abortion. The aim of this study was determine the effect A. aqueous extract on estrous cycle pre- postimplantation rats its mechanism action. cycles Wistar were monitored before, during after oral administration distilled water (control) or (62.5, 125, 250, 500, 1000 mg/kg/day). Furthermore, pregnant received above doses days...
L'objectif de ce travail est décrire le système collecte et d'évacuation des boues vidange à Bafoussam, d'en relever les insuffisances en vue proposer une méthode pour meilleure gestion. Les acteurs leurs rôles dans la chaîne gestion ont été identifiés. collectées, caractérisées effets potentiels sur populations environnantes du site décharge évalués. principaux résultats montré que sont gérées manière autonome deux types d'ouvrages : fosses septiques (49 %) latrines (59 %). intervenant...
