Evidence of the establishment of Cotesia flavipes (Hymenoptera: Braconidae), a parasitoid of cereal stemborers, and its host range expansion in Ethiopia
(Cambridge University Press, 2003-04)
Three lepidopteran cereal stemborers, Chilo partellus (Swinhoe) (Crambidae), Busseola fusca Fuller, and Sesamia calamistis Hampson (Noctuidae) were collected from maize and sorghum in Ethiopia. The noctuid stemborers are ...
Parasitism of lepidopterous stem borers in cultivated and natural habitats.
(Journal of Insect Science, 2010-05)
Plant infestation, stem borer density, parasitism, and parasitoid abundance were assessed during
two years in two host plants, Zea mays (L.) (Cyperales: Poaceae) and Sorghum bicolor (L.)
(Cyperales: Poaceae), in cultivated ...
Factors Affecting Stem Borer Parasitoid Species Diversity and Parasitism in Cultivated and Natural Habitats
(Entomological Society of America, 201)
The effects of biotic and abiotic factors on stem borer parasitoid diversity, abundance, and parasitism were studied in cultivated and natural habitats in four agroecological zones in Kenya. Comparing habitat types, we ...
Cereal yield losses caused by lepidopterous stemborers at different nitrogen fertilizer rates in Ethiopia
(Wiley, 2006-05)
Field trials were carried out at three locations in the cool-wet western and one location in the semiarid eastern ecozones of the Amhara State of Ethiopia to determine the effects of nitrogen fertilizer on pest infestation ...
Effect of the host plant on the survivorship of parasitized Chilo partellus Swinhoe (Lepidoptera: Crambidae) larvae and performance of its larval parasitoid Cotesia flavipes Cameron (Hymenoptera: Braconidae)
(Elsevier, 2005-02)
The effect of wild and cultivated gramineous hosts on the survivorship and weight of parasitized Chilo partellus larvae and on the performance of its larval parasitoid Cotesia flavipes were studied under laboratory conditions, ...
Comparative evaluation of Cotesia flavipes and C. sesamiae (Hymenoptera: Braconidae) for the management of Chilo partellus (Lepidoptera: Pyralidae) in Kenya
(Cambridge University Press, 1999-02)
Cotesia flavipes Cameron, a gregarious larval endoparasitoid native to the Indo-Australian region, was imported from Pakistan and released in Kenya in 1993 for management of the exotic stemborer, Chilo partellus (Swinhoe). ...
Ecological management of cereal stem borers in Ethiopia
(2014-06-23)
Three lepidopterous stem borers were reported on maize in Ethiopia. Although complete crop loss is evident in some areas, the average yield loss of maize caused by cereal stem borers in Ethiopia can be estimated between ...
Morphological variation of Ridged Frogs of the Taita Hills, Kenya
(Firenze University Press, 2011)
Comparing of morphological character variation within taxa continues to play an important role in improving species inventories. Using morphometrical and non-meristic morphological adult characters, the diversity of the ...
Distribution and Relative Importance of Cereal Stem Borers and their Natural Enemies in the Semi-Arid and Cool-Wet Ecozones of the Amhara State of Ethiopia.
(Taylor & Francis Group, 2006)
The distribution and relative importance of lepidopteran and coleopteran stem borers and their natural enemies on maize and sorghum were studied in cereal growing zones of the Amhara State of Ethiopia from 2003 to 2004. ...
Effect of Cropping Systems on Cereal Stemborers in the Cool-Wet and Semi-Arid Ecozones of the Amhara Region of Ethiopia.
(John Wiley & Sons, Inc., 2007)
1 Field experiments were conducted on maize and 1 sorghum at three locations in the Amhara state of Ethiopia to determine the effects of mixed cropping on stemborer infestation, borer natural enemies and grain yields. In ...
