Diversity of fruit flies (Diptera: Tephritidae) attacking Psidium guajava L. (Myrtaceae) in two agro-ecological zones of Northern Cameroon
Guava (Psidium guajava L.), a fruit of high nutritional and economic value, is highly susceptible to infestation by tephritid fruit flies (Diptera), posing a significant threat to its production. To address this issue, a biodiversity study was conducted during two fruiting guava season (2020 – 2021), in six orchards located in two agro-ecological zones of Cameroon: the Sudano-Sahelian Savannah and the High Guinea...

Generation and characterization of doubled haploids maize (Zea mays L.) in sub-Saharan Africa
Doubled haploid (DH) inbred lines are an invaluable technology for maize genetics and hybrid breeding. However, in sub-Saharan Africa (SSA), the use of double haploid technology in maize breeding is uncommon, despite its potential to improve the development of new maize varieties. This research, conducted at the Farako-Bâ research station of the Institute of Environment and Agricultural Research (INERA) in Burkina...

Screening for stem rust (Puccinia graminis f.sp. tritici) resistance in selected wheat (Triticum aestivum L.) lines
Stem rust, caused by Puccinia graminis f.sp. tritici (Pgt), is a major threat to wheat (Triticum aestivum L.) production due to increased susceptibility. This study aimed to identify wheat lines in the 16th Stem Rust Resistance Screening Nursery (SRRSN) with seedling and adult plant resistance (APR) to wheat stem rust. A two-season field experiment was conducted at (KALRO) Njoro using a 12×12 partially balanced...

Pathogenicity test of four fungi pathogens responsible for cabbages (Brassica oleracea L.) diseases and their in-vitro control using medicinal plants and medicinal mushroom extracts in the Western highlands of Cameroon
Diseased cabbages are known for post-harvest and financial losses for farmers. The study evaluated the pathogenicity of the fungi species identified from diseased cabbages and in-vitro control using biological control. For the pathogenicity test, soil was sterilized and 100 cabbages planted in polythene bags. After 65 days of growth, healthy cabbages were infused with 105 spores in 1 miles of glucose solution per...

Control of endophytic fungi in the micropropagation of caçari (Myrciaria dubia (Kunth) McVaugh)
The micropropagation of camu-camu (Myrciaria dubia) is frequently compromised by endogenous fungal contamination, requiring effective fungicides for explant disinfection. This study evaluated the efficiency of systemic fungicides (strobilurins, triazoles, benzimidazoles, phenylpyridinamines, and aromatic hydrocarbons) in controlling 20 endophytic fungal isolates associated with camu-camu, through two stages: (1) in...

Inventory of different fungi in quinoa seed samples and investigation of control methods in Burkina Faso
This study investigated quinoa's susceptibility to fungal diseases in Burkina Faso, identifying pathogens and assessing management strategies. Researchers used naturally infested seeds, seeds treated with essential oils and chemical fungicides, and seedlings, employing a blotting paper method with a completely randomized design (16 replicates per treatment) to identify fungal species based on their...
