The survivorship, fecundity and development time (egg to adult) of Cicadulina storeyi China, C. arachidis China and C. ghaurii Dabrowski were studied at three constant temperatures (20, 25 and 30 .C). Additional tests were conducted to descriptionbe maize streak virus (MSV) transmission by C. ara...

The effects of maize variety and storage form on development of the maize weevil, Sitophilus zeamais Motschulsky, were studied under artificial infestation at 25 ± 2 °C and 70 ± 5% r.h. in the laboratory. Three improved West African maize varieties, Abeleehi, EV8725-SR, Pop63-SR and the local var...

An Agrobacterium-mediated transformation protocol was tested using eight clones of Musa with different ploidy and genomic background. These were selected to represent several major groups of Musa including dessert and highland bananas (AAA), cooking bananas (ABB), improved plantain hybrids (AAB X...

Seven viruses are known on maize in tropical Africa, however, information is still scanty. MSV is widely distributed in sub-Saharan Africa; other viruses are less widely spread or only of local importance. Information on viruses and virus diseases is useful to plant breeders in setting priorities...

Host-plant resistance (HPR) to insect pests is considered one of the key tactics for insect control, particularly in developing countries where utilization of other control methods such as pesticides is often difficult or unwise. The search for more sustainable methods of pest control, make host-...
