Paperback. Zustand: new. Paperback. Cowpeas (Vigna unguiculata L. Walp.) and millet (Pennisetum glaucum (L.) R. Br.) rank first among the legumes and cereals produced and consumed in Niger. However, the production of these crops is hampered by numerous insect pests that cause yield losses of 80 to 100 percent if no control measures are implemented. The use of biopesticides to control insect pests has proven to be effective, less costly, environmentally friendly, and non-toxic to humans and animals. Extracts from the neem tree (Azadirachta indica A. Juss) are effective against insect pests of many crops. Its active ingredient (azadirachtin) works by disrupting the insect's feeding behavior and hormonal cycle, thereby preventing the insect's normal development. These studies allowed us to evaluate the effectiveness of various formulations of the neem-based biopesticide against pests of cowpea and the millet stem borer (C. ignefusalis). By reducing pest infestation, neem extracts have led to a significant increase in the yields of these crops. This item is printed on demand.

Br.) occupent les premieres places des legumineuses et des cereales produites et consommees au Niger. Cependant, la production de ces cultures, est entravee par des nombreux insectes ravageurs provoquant des pertes de production de 80 a 100% si aucune mesure de controle n'est appliquee. L'utilisation des biopesticides pour lutter contre les insectes ravageurs s'est averee efficace, moins couteux, ecologiques et non toxiques pour l'homme et les animaux. Les extraits du neem Azadirachta indica A. Juss sont efficaces contre les insectes ravageurs de nombreuses cultures.

Paperback. Zustand: new. Paperback. Il fagiolo dall'occhio (Vigna unguiculata L. Walp.) e il miglio (Pennisetum glaucum (L.) R. Br.) occupano i primi posti tra i legumi e i cereali prodotti e consumati in Niger. Tuttavia, la produzione di queste colture e ostacolata da numerosi insetti nocivi che causano perdite di produzione comprese tra l'80 e il 100% se non vengono applicate misure di controllo. L'uso dei biopesticidi per combattere gli insetti nocivi si e dimostrato efficace, meno costoso, ecologico e non tossico per l'uomo e gli animali. Gli estratti di neem (Azadirachta indica A. Juss) sono efficaci contro i parassiti di numerose colture. I suoi principi attivi (azadiractina) agiscono interferendo con l'alimentazione dell'insetto e con il suo ciclo ormonale, impedendone cosi il normale sviluppo. Questi studi ci hanno permesso di valutare l'efficacia di diverse formulazioni del biopesticida a base di neem sugli insetti nocivi del fagiolo dall'occhio e sul punteruolo dello stelo del miglio (C. ignefusalis). Riducendo l'infestazione da insetti nocivi, gli estratti di neem hanno consentito un aumento significativo delle rese di queste colture. This item is printed on demand.

Paperback. Zustand: new. Paperback. Die Niebe-Bohne (Vigna unguiculata L. Walp.) und die Hirse (Pennisetum glaucum (L.) R. Br.) nehmen bei den im Niger angebauten und verzehrten Huelsenfruechten und Getreidesorten die Spitzenplaetze ein. Der Anbau dieser Kulturen wird jedoch durch zahlreiche Schaedlinge beeintraechtigt, die ohne entsprechende Bekaempfungsmassnahmen zu Ertragsverlusten von 80 bis 100 % fuehren. Der Einsatz von Biopestiziden zur Bekaempfung von Schaedlingen hat sich als wirksam, kostenguenstiger, umweltfreundlich und fuer Mensch und Tier ungiftig erwiesen. Extrakte aus dem Neembaum (Azadirachta indica A. Juss) sind wirksam gegen Schaedlinge zahlreicher Kulturpflanzen. Seine Wirkstoffe (Azadirachtin) wirken, indem sie die Nahrungsaufnahme des Insekts sowie dessen Hormonhaushalt stoeren und so die normale Entwicklung des Insekts verhindern. Anhand dieser Studien konnten wir die Wirksamkeit verschiedener Formulierungen des Biopestizids auf Neem-Basis gegen Schaedlinge der Pomblume und den Hirse-Staengelbohrer C. ignefusalis bewerten. Durch die Verringerung des Schaedlingsbefalls haben die Neem-Extrakte zu einer signifikanten Steigerung der Ertraege dieser Kulturen gefuehrt. This item is printed on demand.
