The present work aims to assess the pathogenicity of the conidia of six isolates of Metarhizium anisopliae and two isolates of Beauveria bassiana on Helicoverpa armigera in order to select the most promising ones for developing a microbiological product to be used in cotton fields. The pathogenic...

This study sought to identify new sources of resistance to cowpea aphids (CPA) using molecular and phenotypic approaches and the inheritance pattern. Sixty cowpea genotypes were phenotyped for resistance to CPA using insect proof cages and further confirmed using markers linked to aphid resistanc...

Cassava mosaic disease (CMD), now known to be caused by cassava mosaic geminiviruses (Family Geminiviridae; Genus Begomovirus), was first reported in East Africa in 1894. Epidemics occurred in Madagascar and Uganda in the 1930s and 1940s, and more localised rapid spread of CMD was observed in par...

Nematode parasitic disease, attributed mainly Haemonchus contortus, is the greatest disease problem of small ruminants in Malaysia. This thesis comprises 6 studies on the emergence of anthelmintic resistance in these parasites, and how control may be managed by exploiting the nematophagous fungus...

From 1999 till 2001, management strategies for the reduction of aflatoxin in maize were developed in participatory tests with farmers. After 6 months of storage, maize in bags contained more aflatoxin than maize in traditional farmers’ stores. Harvesting maize late increased the risk of aflatoxin...
