All Peer-Reviewed Publications

Naive females of Cotesia flavipes Cameron and Cotesia sesamiae (Cameron) were attracted, in a T-tube olfactometer, to volatile kairomones from frass produced by Chilo partellus (Swinhoe), Chilo orichalcociliellus Strand, Sesamia calamistis Hampson, and Busseola fusca (Fuller) fed on maize (Zea mays L.), sorghum [Sorghum bicolor (L.)], and napier grass (Pen. nisetum purpureum Schumach). In dual-choice tests, C. flavipes and C. sesamiae were generally unable to discriminate between volatiles from frass produced by any of the four different stemborer species fed on maize stalk. When larvae of C. partellus and S. calamistis were washed in distilled water, their acceptance by both …

Diel Activity Patterns And Host Preferences Of Glossina Fuscipes Fuscipes (Diptera: Glossinidae) Along The Shores Of Lake Victoria, Kenya, M. M. Mohamed-Ahmed, A. Odulaja

All Peer-Reviewed Publications

Diurnal activity patterns and host preference of Glossina fuscipes fuscipes Newstead were studied in forest and linear habitats along Lake Victoria shore, Kenya. The objective was to identify the preferred hosts of G. f. fuscipes, the emanations of which may be attractive to this species. Hourly catches of flies in biconical traps were related to changes in the weather and the prevalence of hosts in the vicinity of traps. Flies were mainly active between 0800 and 1600 h, with males peaking around 1100 h and females around 1300 h. Activity of flies correlated directly with light intensity and temperature, but …

Natural Enemies Of Cereal Stemborers In East Africa: A Review, M. J. Bonhof, W. A. Overholt, A. Van Huis, A. Polaszek

All Peer-Reviewed Publications

The noctuids Busseola fusca and Sesamia calamistis and the pyraloids Chilo partellus, Chilo orichakocilielhis and Eldana saccharina are the most important stemborers of maize in East Africa. A wide range of egg, larval and pupal parasitoids of stemborers have been identified, but information on predators, nematodes and microbial pathogens is less extensive. The most abundant and widespread parasitoids in the East African region are the egg parasitoids Telenomus spp. and Trichogramma spp., the larval parasitoids Cotesia sesamiae and Sturmiopsis parasitica and the pupal parasitoids Pediobiusfiirvus and Dentichasmias busseolae. Predators, such as ants, spiders and earwigs can cause high mortality of …

Geographic Variation In Host Selection Behaviour And Reproductive Success In The Stemborer Parasitoid Cotesia Flavipes (Hymenoptera: Braconidae), R. P.J. Potting, L. E.M. Vet, W. A. Overholt

All Peer-Reviewed Publications

Local parasitoid populations may be adapted to their sympatric major plant host complex. Parasitoid strains may thus differ in their propensity to search for a particular micro-habitat or host or they may differ in their physiological compatibility with particular plant or host species. Cotesiaflavipes Cameron, a larval parasitoid used worldwide in biological control against tropical stemborers, has a wide host range in diverse habitats. The existence of plant and/or host specific strains in C. flavipes has been postulated. To provide insight into the existence of strains in C. flavipes, we compared the plant/host complex selection behaviour, and physiological compatibility with …
