Push–pull Agricultural Pest Management
Push–pull technology is an intercropping strategy for controlling agricultural pests by using repellent "push" plants and trap "pull" plants. For example, cereal crops like maize or sorghum are often infested by stem borers. Grasses planted around the perimeter of the crop attract and trap the pests, whereas other plants, like ''Desmodium'', planted between the rows of maize, repel the pests and control the parasitic plant ''Striga''. Push–pull technology was developed at the International Centre of Insect Physiology and Ecology (ICIPE) in Kenya in collaboration with Rothamsted Research, UK. and national partners. This technology has been taught to smallholder farmers through collaborations with universities, NGOs and national research organizations. How push–pull works Push–pull technology involves use of behaviour-modifying stimuli to manipulate the distribution and abundance of stemborers and beneficial insects for management of stemborer pests. It is based on i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Desmodium Uncinatum
''Desmodium uncinatum'', the silverleaf desmodium, is a species of flowering plant in the family Fabaceae, native to Latin America, and introduced as a fodder to various locales in Africa, India, New Guinea, Australia and Hawaii. Although chiefly a fodder, it can also be used for pasture, deferred feed, cut-and-carry, hay, ground cover, and mulch. It is considered invasive in Australia and Hawaii. This species of ''Desmodium'' has also found use in the push-pull technology for pest management where it is grown as an intercrop between rows of a cereal crop to control stem-boring insects and fall armyworm The fall armyworm (''Spodoptera frugiperda'') is a species in the order Lepidoptera and one of the species of the fall armyworm moths distinguished by their larval life stage.

Melinis Minutiflora
''Melinis minutiflora'', commonly known as molasses grass, is a species of grass. It is a perennial grass native to Africa, where it occurs in disjunct populations (an arc from central Angola to Cameroon in western central africa, the areas around Ruwenzori Mountains and Mount Kenya in eastern Africa. Its seeds are dispersed by wind. Molasses grass usually grows to be thirty to sixty inches tall, and it forms mats when its long, slender stems lay on top of each other in layers up to four feet deep. Molasses grass can spread up other plants, using them as support, like a vine. It has fragrant foliage and colorful inflorescences. It blooms for short periods with differing bloom times depending on where the grass is located. Molasses grass generally flowers in the southern hemisphere between April and June and in the northern hemisphere in November.

Soil Organic Matter
Soil organic matter (SOM) is the organic matter component of soil, consisting of plant and animal detritus at various stages of decomposition, cells and tissues of soil microbes, and substances that soil microbes synthesize. SOM provides numerous benefits to the physical and chemical properties of soil and its capacity to provide regulatory ecosystem services. SOM is especially critical for soil functions and quality. The benefits of SOM result from a number of complex, interactive, edaphic factors; a non-exhaustive list of these benefits to soil function includes improvement of soil structure, aggregation, water retention, soil biodiversity, absorption and retention of pollutants, buffering capacity, and the cycling and storage of plant nutrients. SOM increases soil fertility by providing cation exchange sites and being a reserve of plant nutrients, especially nitrogen (N), phosphorus (P), and sulfur (S), along with micronutrients, which the mineralization of SOM slowly release ...

Semiochemical
A semiochemical, from the Greek σημεῖον (''semeion''), meaning "signal", is a chemical substance or mixture released by an organism that affects the behaviors of other individuals. Semiochemical communication can be divided into two broad classes: communication between individuals of the same species (intraspecific) or communication between different species (interspecific). It is usually used in the field of chemical ecology to encompass pheromones, allomones, kairomones, attractants and repellents. Many insects, including parasitic insects, use semiochemicals. Pheromones are intraspecific signals that aid in finding mates, food and habitat resources, warning of enemies, and avoiding competition. Interspecific signals known as allomones and kairomones have similar functions. In nature Pheromone A pheromone (from Greek ''phero'' "to bear" + ''hormone'' from Greek – "impetus") is a secreted or excreted chemical factor that triggers a social response in members of ...

Ocimene
Ocimenes are a group of isomeric hydrocarbons. The ocimenes are monoterpenes found within a variety of plants and fruits. α-Ocimene and the two β-ocimenes differ in the position of the isolated double bond: it is terminal in the alpha isomer. α-Ocimene is ''cis-''3,7-dimethyl-1,3,7-octatriene. β-Ocimene is ''trans-''3,7-dimethyl-1,3,6-octatriene. β-Ocimene exists in two stereoisomeric forms, ''cis'' and ''trans,'' with respect to the central double bond. The ocimenes are often found naturally as mixtures of the various forms. The mixture, as well as the pure compounds, are oils with a pleasant odor. They are used in perfumery for their sweet herbal scent, and are believed to act as plant defense and have anti-fungal properties. Like the related acyclic terpene myrcene, ocimenes are unstable in air.Karl-Georg Fahlbusch, Franz-Josef Hammerschmidt, Johannes Panten, Wilhelm Pickenhagen, Dietmar Schatkowski, Kurt Bauer, Dorothea Garbe, Horst Surburg "Flavors and Fragrances ...

Desmodium Intortum
''Desmodium intortum'', known as greenleaf desmodium and also as beggarlice along with other members of its genus, is a species of flowering plant in the genus ''Desmodium'', native to Mexico, Central America, northern South America, the Galápagos, Haiti and Jamaica. A nitrogen-fixing fodder crop, it has been introduced to the rest of the world's tropics, including Africa, India, Australia, New Guinea and Taiwan ''Desmodium intortum'' is used in push–pull agricultural pest management since it contains potent secondary metabolites that are released into the soil and aerially. Inter-cropped in maize and sorghum fields, it repels ''Chilo partellus'', a stem-boring grass moth The Crambidae are the grass moth family of lepidopterans. They are variable in appearance, the nominal subfamily Crambinae (grass moths) taking up closely folded postures on grass stems where they are inconspicuous, while other subfamilies includ ..., and suppresses witchweeds, including Asiatic witchwee ...

Legume
A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. Legumes are grown agriculturally, primarily for human consumption, for livestock forage and silage, and as soil-enhancing green manure. Well-known legumes include beans, soybeans, chickpeas, peanuts, lentils, lupins, mesquite, carob, tamarind, alfalfa, and clover. Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces (opens along a seam) on two sides. Legumes are notable in that most of them have symbiotic nitrogen-fixing bacteria in structures called root nodules. For that reason, they play a key role in crop rotation. Terminology The term ''pulse'', as used by the United Nations' Food and Agriculture Organization (FAO), is reserved for legume crops harvested solely for the dry seed. This excludes green beans and green peas, which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stemborer
A stemborer (stem borer) is any insect larva, or arthropod, that bores into plant stems. However the term most frequently refers among the Coleoptera to the larva of certain longhorn beetles such as '' Dorysthenes buqueti'' and those of the genus '' Oberea'', and among the Lepidoptera to certain moths of the Crambidae, Castniidae, Gelechiidae, Nolidae, and Pyralidae families. Stem borers include: ;Coleoptera *Banana stemborer weevil ('' Cosmopolites sordidus'') * Coffee white stem borer (''Xylotrechus quadripes'') * Sugarcane longhorn stemborer (''Dorysthenes buqueti'') ;Lepidoptera *African pink stemborer (''Sesamia calamistis'') * African white stemborer (''Maliarpha separatella'') *Asiatic rice stemborer (striped rice stemborer, ''Chilo suppressalis'') * Banana stem borer (''Telchin licus'') * Egyptian stemborer (''Earias insulana'') *Gold-fringed rice stemborer (''Chilo auricilius'') *Pearl millet stem borer (''Coniesta ignefusalis'') *Spotted stem borer (''Chilo partellus'') * ...
