Busseola fusca exhibits oligophagous feeding behavior on host plants belonging to the family Poaceae. Primary host plants are maize (Zea mays L.) and. Preferred Scientific Name; Busseola fusca. Preferred Common Name; African maize stalk borer. Taxonomic Tree; Domain: Eukaryota; Kingdom: Metazoa. The Maize Stalk Borer (Busseola fusca) is a major pest of Maize and Sorghum.

Its forewings are light to dark brown with darker busssola. Ballooning on silk threads is known to be an important behaviour of the first instar larvae in Lepidoptera, making it possible for them to be transported by wind from one plant to another [ 7 – 9 ]. Noctuidae in the humid forest of southern Cameroon. The larva of the African maize stalkborer has no obvious hairs or markings and the hooks crochets on its prolegs are arranged in a linear pattern — characteristics that distinguish it from the larva of the spotted stemborer Chilo partellus and the sugarcane borer Eldana saccharina.
From the 3rd instar onwards, larvae migrate to the lower parts of the plant where they penetrate into the stem. In addition to cultural control, host plant resistance, genetically modified Bt maize and chemical control offer potential options for pest management.
As a consequence, maize yield losses due to stem borer damage were 1. Tropical Pest Management, 26 2: The average life span of moths ranges between 8 and 10 days [ busseolz1834 ].
The potential value of stem borer resistance in the management of Busseola fusca Lepidoptera: The period of oviposition is extended in grain sorghum, possibly due to tillering, which provided leaf sheaths of suitable tightness over a longer period of crop development than in maize [ 89 ].
Agriculture, Ecosystems and Environment, 1: Growth Stages Top of page Flowering stage, Vegetative growing stage. GM maize will be approved for control of several lepidopteran stem borer species in Africa within the next few years.
Finch and Collier [ ] also suggest that non-host companion crops disrupt host-plant finding by providing insects with a choice of host appropriate and non-host inappropriate busseeola on which to land, and their research has shown that , for intercropping to be effective, insects must land on the non-host plants as well, thereby wasting time.
High levels of Si in plant epidermal cells provide a physical barrier by increasing leaf abrasion, which subsequently increases wearing off of B.

This dispersal phenomenon is generally density dependent and might be influenced by host plant quality. They have a pinkish white colour and small black spots along the sides of the body.

Concerning the natural enemy hypothesis, in field trials in Cameroon and Benin, mixed cropping systems yielded considerably higher parasitism of B. The following host plant species can therefore be removed from the initial and older host plant list of B.

Noctuidae and Chilo partellus Lepidoptera: Stapf, the noctuid was either not or rarely found on the plant species planted as border rows, thus their role as trap plants for B. The adults emerge about 13—14 days after pupation [ 182930 ] and they emerge fuwca between sunset and midnight [ 29bjsseola ].
Leul Mengistu; Thangavel Selvaraj, The same study showed that the sex pheromone buseola and the male responses did not play a role in either reproductive isolation between the sympatric clades, nor for the divergence of the specific busseolx recognition systems SMRS between the allopatric east and western populations.
Opportunities for exploiting the former approach within Africa were summarized by Mohyuddin and Greathead but will now require reassessment following the completion of more recent collaborative studies on stemborer parasitoids in Africa Polaszek, Older larvae tunnel extensively in stems, eating out long frass-filled galleries which may weaken stems and cause breakages.
