A fractional-order fall armyworm-maize biomass model with naturally beneficial insects and optimal farming awareness.
(Elsevier, 2021-11-01)
Maize remains an important food crop in Africa. However, the production of this crop, and consequently the livelihood of the growers are threatened by the invasion and widespread infestation of the fall armyworm which ...
The impact of stable flies (stomoxys calcitrans l.) on small stock production in Bodibeng, Bothatogo and Sehithwa in the north west district, Botswana; a survey study.
(Scienceline Publishers, 2022-03-25)
Stable fly, Stomoxys calcitrans L. (Diptera: Muscidae) is a globally recognized livestock pest of economic importance, which also attacks wild animals, pets and humans. These flies frequently feed on the forelegs of animals ...
Dynamics for a non-autonomous fall armyworm-maize interaction model with a saturation functional response
(AIMS Press, 2021-11-09)
In this study, we present a non-autonomous model with a Holling type II functional response, to study the complex dynamics for fall armyworm-maize biomass interacting in a periodic environment. Understanding how seasonal ...
A fractional-order Trypanosoma brucei rhodesiense model with vector saturation and temperature dependent parameters.
(Springer Open, 2020-06-11)
Temperature is one of the integral environmental drivers that strongly affect the distribution and density of tsetse fly population. Precisely, ectotherm performance measures, such as development rate, survival probability ...
Quadratic sequences in Pythagorean triples
(American Institute of Physics, 2022-06-16)
Using the Euclid's formula, we obtain an alternative formula for generating Pythagorean triples, both primitive and non-primitive. It easy to classify Pythagorean triples using this formula based on the divisibility of the ...
Changes in Health-related Parameters Associated with Sports Performance Enhancement Drugs.
(Thieme Gruppe, 2022-12-02)
The purpose of this study was to evaluate changes in health-related parameters caused by the administration of anabolic-androgenic steroids and fat-burning drugs during a 6-month competition preparation period. The ...
Smallholder agriculture in African dryland agroecosystems has limited impact on trophic group composition, but affects arthropod provision of ecosystem services.
(Elsevier B.V., 2024-04-01)
Agricultural intensification is a major driver of biodiversity loss, but the majority of studies highlighting these threats come from industrialised agriculture in temperate countries of the global North. However, more ...
Cattle dung in aquatic habitats alters mosquito predatory biocontrol dynamics
(Elsevier, 2022-09)
Anthropogenic land use changes influence ecosystem functioning and may alter trophic interactions. Intensification of free–range pastoral farming could promote degradation of aquatic habitats, with nutrient inputs adversely ...
Evaluation of two Non-Edible, Wild Indigenous Botswana Crops (Croton megalobotrys (Motsebi/Letsebi/Moshoole) and Ricinus communis (Mokhure)) as Potential Feedstocks for Petroleum and Cosmetic Industries
(EAST AFRICAN NATURE & SCIENCE ORGANIZATION, 2021-12-07)
Croton megalobotrys and Ricinus cummunis plants produce high-quality nonedible seed oils at relatively high quantities of 39.65 ± 0.06 % w/w to 53.74 ± 0.04 % w/w. The Iodine values of 85.97 ± 1.62 g I2/100 g to 96.51 ± ...
Unlocking the potential of smallholder dairy farm: Evidence from the central highland of Ethiopia.
(Elsevier, 2022-12-01)
Sustainable livestock farming practices have the potential to improve productivity and high income, reduce greenhouse gases, and improve household food security. Despite previous efforts to disseminate these technologies, ...
