Since 2015, the stink locust (Zonocerus variegatus) population has been proliferating in the Mawanga sector, in the territory of Kasongo Lunda, an administrative entity in the province of Kwango in the Democratic Republic of Congo. This insect ravages food crops and fruit trees, devouring their leaves and bark and causing the host plant to wither. To assess the insecticidal action of four total extracts based on Nicotiana tabacum, Tephrosia vogelii, Zingiber officinale and Capsicum frutescens on the stink locust, a field trial involving a cassava crop was set up between November 2020 and December 2021 in the Emmaüs village in the Mawanga sector, Kasongo Lunda territory, in the Democratic Republic of Congo. Tobacco and ginger showed the lowest incidence and severity of locust damage. For the latter parameter, their performance was equal to that of deltamethrin. These two plant species showed potential for use in the manufacture of biopesticides to help farmers control the locust.

Abstract
Since 2015, the stink locust (Zonocerus variegatus) population has been proliferating in the Mawanga sector, in the territory of Kasongo Lunda, an administrative entity in the province of Kwango in the Democratic Republic of Congo.

To assess the insecticidal action of four total extracts based on Nicotiana tabacum, Tephrosia vogelii, Zingiber officinale and Capsicum frutescens on the stink locust, a field trial involving a cassava crop was set up between November 2020 and December 2021 in the Emmaüs village in the Mawanga sector, Kasongo Lunda territory, in the Democratic Republic of Congo.

Abstract: (french)
Depuis 2015, la population de criquet puant (Zonocerus variegatus) prolifère dans le secteur de Mawanga, territoire de Kasongo Lunda, entité administrative de la province de Kwango en République Démocratique du Congo. Cet insecte ravage les cultures vivrières et les arbres fruitiers, dont il dévore feuilles et écorce provoquant ainsi le dépérissement de la plante hôte. Pour apprécier l’action insecticide de quatre extraits totaux à base de Nicotiana tabacum, Tephrosia vogelii, Zingiber officinale et Capsicum frutescens sur le criquet puant, un essai en plein champ portant sur une culture de manioc a été installé entre novembre 2020 et décembre 2021 au village Emmaüs dans le secteur de Mawanga, territoire de Kasongo Lunda, en République Démocratique du Congo. Les produits fabriqués avec le tabac ou le gingembre ont déterminé le niveau d’incidence et de sévérité les plus faibles des dégâts du criquet puant. Pour ce dernier paramètre, ils ont manifesté une performance égale à celle de deltaméthrine. Ces deux espèces végétales ont démontré des potentialités susceptibles d’être valorisées dans la fabrication des biopesticides au profit des agriculteurs pour lutter contre le criquet puant.
