Comparative efficacy and cost analysis of albendazole, levamisole, and ivermectin on West African dwarf sheep in Makurdi Benue state Nigeria

March 2024

Helminthosis and helminths resistance to anthelmintic is a great concern in the management of sheep. The efficacy of three different anthelminthics was studied in sheep. Three groups of sheep comprising seven animals each were treated with three different anthelmintics (albendazole, ivermectin and levamisole). Faecal samples were collected from each group before and after treatment. The faecal egg count (FEC) was...

Role of crop diversification on occurrence of sap-sucking insect pests and their associated natural enemies on tomato

February 2024

Tomato production is constrained by arthropod pests and diseases. Among the arthropod pests, sap-sucking insect pests such as whiteflies (Bemisia tabaci (Gennadius 1889)), aphids (Aphis spp.) and Thrips sp. are the insect pests of economic importance in the study area. The overall result indicated that intercropping significantly reduced the population of these insect pests compared to sole tomato. The most effective...
