“…Reasons for the recent successful establishment of C. fl avipes are not clear but may include better targeting of areas where C. partellus is abundant. Laboratory studies indicate that releasing the parasitoid where B. fusca and/or Eldana saccharina are predominant will most likely results in failure to establish since the stem borers are not suitable hosts (Ngi-Song et al 1995;Overholt et al 2003).…”

Cotesia fl avipes Cameron (Hymenoptera: Braconidae) was fi rst imported into Kenya in 1991 from Pakistan for control of Chilo partellus (Swinhoe) (Lepidoptera: Crambidae). First releases were made at the Kenya coast in 1993 and a few recoveries of the parasitoid were made the following year. Additional foreign exploration for C. fl avipes was conducted in central India in 1996 and 1998, which resulted in additional importation of the parasitoid for subsequent releases in eastern and southern Africa. Region-wide releases commenced with releases in Mozambique in 1996

“…Although several biological control programs involving augmentative release of parasitoids have been carried out in Africa (Neuenschwander 2003;Overholt et al 2003;Tamò et al 2003) most of them were implemented without farmers' involvement. The innovative approach of our program was the full involvement of farmers during the whole process.…”

Biological control of the millet head miner Heliocheilus albipunctella in the Sahelian region by augmentative releases of the parasitoid wasp Habrobracon hebetor: effectiveness and farmers’ perceptions

On-farm augmentative releases of the parasitoid Habrobracon hebetor (Say) for controlling the millet head miner (MHM) Heliocheilus albipunctella (de Joannis) was experimented in Burkina Faso, Mali and Niger from 2007 to 2009. In addition, a survey of farmers' perceptions of insect pests, with particular focus on MHM, and the biological control program (BCP) was carried out. Our findings indicate a significant increase of MHM parasitization rate after the releases with up to 97% mortality. The survey on farmer's perceptions revealed a fair knowledge of the MHM and the ability of farmers to describe the pest and its damage. Farmers claimed that the biocontrol agent H. hebetor is effective and perceived a significant gain in grain yield due to this control strategy. Implications of these findings for a large extension of the MHM biocontrol program are discussed.

“…The control of the maize stem borer, Chilo partellus Swinhoe, in Kenya and Tanzania is attributed to a gregarious endoparasitoid, Cotesia flavipes Cameron, which was introduced from Asia by the International Centre of Insect Physiology and Ecology (ICIPE) (Omwega et al., 1995; Overholt et al., 1997, 2003). In the area of varietal resistance/tolerance to pests, ICIPE has shown an effective, well‐focused IPM strategy for the stem borers of sorghum in Kendu Bay and Oyugis in western Kenya (Saxena et al., 1989).…”

In sustainable agricultural development, integrated pest management (IPM) can play a key role in the reduction of crop losses, thereby increasing productivity while minimizing environmental contamination and health hazards. In recent years, agricultural research and development partners have pioneered outstanding contributions in IPM, notably in varietal resistance against pests, biological control of alien invasive species, substitution of inorganic pesticides with biopesticides, new export market opportunities, and new tools in biotechnology. Success stories are not limited to these areas, but are also found in the areas of human capital development, information management, and participatory approaches. The potential of IPM to contribute to poverty alleviation and food security is, however, poorly realized in Africa due to a myriad of factors, including inadequate deployment of high-yielding crop varieties, harmful pesticide regimes, political instability, conflicts in social values and civil wars, inappropriate agricultural policies, biased global trade policies, lack of market information, and poor rural infrastructures. Few African countries have adopted IPM as the official national crop protection policy and there is no framework for resource allocation to support widespread promotion of research and training in IPM. This calls for reshaping and revisiting a number of policies related to food production and agricultural development, in order to encourage partnership and participation in the identification, analysis, advocacy, and follow-up of agricultural policy issues as well as public awareness of the effect of pests and diseases on food security and the environment.

Biological control of gramineous lepidopteran stem borers in sub-Saharan Africa.

Abstract: The biological control of lepidopteran stem borers infesting, maize, sugarcane, sorghum, millet, rice and other valuable gramineous crops in Africa is described in this chapter. The biological control agents for these pests, including predators and parasitoids, are mentioned.
