Cross-mating and oviposition behaviour between strains of Cotesia sesamiae cameron (hymenoptera: braconidae) from Kitale, Mombasa and Mount Kenya

Abstract: 
Stemborers cause 50% yield losses in cereal crops. In Kenya Cotesia sesamiae is one of the parasitoids that has been studied in regard to the control of stemborer pests. In this study the reproductive compatibility of three populations of C. sesamiae was investigated using the noctuid S. calamistis and Busseola fusca as hosts. The output of this work has helped to determine the effect of cross mating and oviposition behaviour of C. sesamia strains and has helped to understand the possible consequences of the introduction and redistribution of C. sesamiae for the sustainable control of stem borers in Africa.
Les foreurs de tige causent 50% des pertes de rendement dans les cultures céréalières. Au Kenya, Cotesia sesamiae est l’un des parasitoïdes qui a été étudié en ce qui concerne le contrôle des ravageurs foreurs de tige. Dans cette étude de la compatibilité en matière de reproduction de trois populations de C. sesamiae a été étudiée en utilisant le calamistis noctuelles et S. Busseola fusca comme hôtes. La sortie de ce travail a contribué à déterminer l’effet de l’accouplement de la Croix et le comportement de ponte des souches de C. Sesamia et a aidé à comprendre les conséquences éventuelles de l’introduction et la redistribution de C. sesamiae pour le contrôle durable des foreurs en Afrique.

About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Crop Protection"
