Effect of transgenic cotton expressing Cry1Ac and Cry2Ab2 protein on entomopathogenic nematodes, Steinernema karii and Heterorhabditis bacteriophora.
Karuri, H.W.; Amata, R.; Amugune, C.N.; Waturu, C.N. (2013)Entomopathogenic nematodes are used in biological control of pests. The cry proteins from insect resistant cotton may affect their infectivity. The effect of Bacillus thuringiensis (Bt) cotton (06Z604D) on infectivity of ... -
Interaction of Fusarium oxysporum f.sp.vasinfectum and the fungal feeding nematode Aphelechus avenae on Bt cotton
Karuri, H.W.; Amata, R.; Amugune, C.N.; Waturu, C.N. (2014)The fungal feeding nematode Aphelenchus avenae (APH) feeds on different species of fungi including Fusarium oxysporum f. sp. vasinfectum (FOV) that causes wilt in cotton. The objective of this study was to assess the ... -
Nematode diversity in soil from a field trial with decomposing Bt cotton expressing Cry1Ac and Cry2Ab2 protein
Karuri, H.W.; Amata, R.; Amugune, C.N.; Waturu, C.N. (2013)The quality of decomposing plant materials may affect the soil community structure. The aim of the study was to determine the impact of decomposing Bt cotton and its isoline on soil nematode diversity. Bt cotton (06Z604D), ... -
Occurrence and distribution of soil nematodes in cotton production areas of Kenya.
Karuri, H.W.; Amata, R.; Amugune, C.N.; Waturu, C.N. (2010)A baseline survey was conducted to determine the occurrence and distribution of soil nematodes associated with cotton in major growing areas in Kenya. Such baseline data on soil nematode abundance, diversity and ecosystem ... -
Reproduction of root knot nematode (Meloidogyne icognita) on Bt cotton expressing Cry1Ac and Cry2Ab2 protein.
Karuri, H.W.; Amata, R.; Amugune, C.N.; Waturu, C.N. (2013)Objective: The sedentary endoparasite Meloidogyne incognita is an important plant parasitic nematode that infects cotton causing significant yield losses. The objective of this study was to evaluate reproduction of M. ...
