An assemblage of approximately 20 moth species belonging to the families Crambidae, Pyralidae and Noctuidae constitute the most important cereal pests in many parts of Africa.

The caterpillars of these moths bore into the stems of maize, sorghum, millet and rice, often killing the plant, and are commonly known as stem or stalk : $ An assemblage of approximately 20 moth species belonging to the families Crambidae, Pyralidae and Noctuidae constitute the most important cereal pests in many African Cereal Stem Borers book of Africa.

The caterpillars of these moths bore into the stems of maize, sorghum, millet and rice, often killing the plant, and are commonly known as stem or stalk borers.

The cereals attacked are grown by smallholders to feed. The economic importance of the stem borer in Africa results in their severe damage that affect directly cereal yield factors such as the density of fertile tillers and the number of effective panicles. The objective of this paper is to describe and discuss the management options of the main prevalent stem borer of cereal crops in Africa.

Host plant resistance, cultural practices, biological Cited by: 1. Abstract This book on the cereal stem African Cereal Stem Borers book of Africa consists of 28 chapters, by various authors, arranged in 4 sections. The 1st section is on economic importance (host plants; maize, West and central Africa; maize and sorghum, East Africa; maize and grain sorghum, southern Africa; sorghum, West Africa; rice, West Africa; rearing maize and sorghum stem borers).

This well-illustrated book provides up-to-date information necessary to the application of integrated pest management (IPM) methods for the control of African cereal stem borers. Important species are characterised by their region, biology and host plants. Control measures currently in use, and those under research, are described.

Of the various insect pests attacking cereal crops in Africa, lepidopteran stem borers are by far the most injurious.

The African stem borer, Busseola fusca, and the spotted stem borer, Chilo partellus, are the most destructive pests of cereal crops in southern Africa. Their control is expensive and requires expertise, as precise timing of pesticide applications is crucial.

Rice is an important cereal crop and is cultivated virtually in all agro-ecological zones in Tanzania. However, production capacity is far below the national requirement.

One of the major reasons for the low yields of rice in Tanzania is damage by insect pests, particularly rice stem borers. Four rice stem borer species reported to infest rice crop in Tanzania includes the white stem borer.

This article is an attempt to summarize the status of knowledge about economically important cereal stem borers in Africa with emphasis on their distribution, pest status and yield losses.

The spotted stem borer is one of the most important stem borers in East and Southern Africa. This pest is not native to Africa, but was accidentally introduced from Asia. It is essentially a pest of hot lowland areas, and it is seldom found above an altitude of m.

for managing cereal stem borers in Africa was developed by scientists of the International Centre of Insect Physiology and Ecology (ICIPE) in Kenya and Rothamsted Research in the United Kingdom, in collaboration with other research organizations in eastern Africa [8].

Eighteen parasitoids were recorded from the African stem borer, Busseola fusca (Fuller), on maize and grain sorghum, in Delmas and Cedara, South Africa. In Delmas, larval parasitism on both crops fluctuated below 20% with occasional peaks of 40–60%. There are several stem-borer species recorded on important cereals such as rice, maize and sorghum as well as on grain legumes like cowpea.

Those of considerable economic importance are: Chilo partellus, Sesamia infer ens, Sesamia eretica, Busseola fusca and Eldana saccharina on maize and sorghum; Sesamia infer ens.

Chilo spp., Maliarpha separatella and Tryporyza incertulas on rice; and. ious endoparasitoids of lepidopteran stem borers of Cram-bidae, Pyralidae, and Noctuidae families. Members of the complex are economically important worldwide as biocon-trol agents of cereal and sugarcane stem borer pests (Pola-szek and Walker ).

sesamiae is the African species of the complex, with a sub-Saharan distribution. This general. Capable of causing yield losses of between 10 and per cent, stem borers are destructive pests affecting cereal crops including maize, rice, sorghum, sugarcane and pearl millet.

An assemblage of approximately 20 moth species belonging to the families Crambidae, Pyralidae and Noctuidae constitute the most important cereal pests in many parts of Africa. The caterpillars of these moths bore into the stems of maize, sorghum, millet and rice, often killing the plant, and are commonly known as stem or stalk : Technical Centre for Agricultural and Rural Cooperation.

The Push-pull strategy uses trap and repellent plants for managing cereal stem borers in maize-based farming systems in Africa. Desmodium plant plays a two-pronged role of repelling the stem-borer. Easy way to protect maize plants from stem borers Friday April 10 Maize farmer, Reuben Onyango, who practices the push-pull technology in his farm in.

I Economic Importance. Chapter 1 Host plantsChapter 1. Polaszek, Z. Khan. Host plants. Introduction. In sub-Saharan Africa stem borers are major biotic constraints to cereal production.

These pests are responsible for losses ranging between % of potential yield under different agroecological conditions (Seshu Reddy and Walker ; De Groote ; De Groote et al.

).Upon hatching, with the exception of Sesamia calamistis that bore directly into the stem (Bosque-Pérez. This study aimed at an assessment of the potential of the egg parasitoid Telenomus isis (Polaszek) as a biological control agent of cereal stem borers.

Therefore, the effects of temperature, host species, host age, and time of host deprivation on the development and the reproductive potential of T. isis were studied in the laboratory. By use of linear regression and a modified Logan model and. Of the various insect pests attacking cereal crops in Africa, lepidopteran stem borers are by far the most injurious.

All 21 economically important stem borers of cultivated grasses in Africa are indigenous except Chilo partellus, which invaded the continent from India, and C. sacchariphagus, which has recently been found in sugarcane in.

Stem borers were monitored at Cedara (KwaZulu-Natal Province), Delmas (Mpumalanga Province) and Brits (North-West Province), South Africa. Moth populations of Busseola fusca were monitored with synthetic sex pheromone traps, while larval populations of the two stem borer species were monitored by scouting maize and grain sorghum fields.

It was determined that Chilo partellus, which invaded. The African maize stalk borer and spotted stem borer cause more damage to cereal crops than any other pests in sub-Saharan Africa.

Stem borers can build up from year to year in fields where. Lepidopteran cereal stem borers in Africa typically occur as complexes of species, with notable regional variation in their distributions.

The noctuids Busseola fusca Fuller and Sesamia calamistis Hampson, and the pyralid Eldana saccharina (Walker), are present throughout most of sub-Saharan Africa, but there are important regional differences in the ecozones they inhabit, and their pest status.

Stem Borers. The stem borers (Busseola fusca, Sesamia calamistis, Eldana saccharina, and Chilo partellus) are among the most important pests of maize in many agroecological zones across the continent including those in Southern Africa. They damage young plants and, without proper control, may also attack the developing ears causing.

Busseola fusca (Lepidoptera: Noctuidae) is an important pest of maize and sorghum in sub-Saharan Africa. One century after its first description by Fuller ininaccurate information based on earlier reports are still propagated on its distribution (e.g., absent from the lower altitudes in East Africa) and host plant range (e.g., feeding on a large range of wild grass species).
