Status and perspectives of struggle against Sitotroga cerealella (Olivier, 1789), pest of cereals in Benin: a short review ABSTRACT Objective: This review article describes the studies on different methods of fighting against Sitotroga cerealella (Angoumois Grain Moth), and the focus was on the use of non-chemical methods to display a biological fight. S. cerealella is one of the most dangerous pests in traditional systems of conservation in Africa and particularly in Benin. Methods and Results: In the search for information about the struggles against the Angoumois grain moth , several published scientific works were consulted . Examination of the results of research on the control of this pest infesting several cereals revealed frequent use of synthetic chemicals such as deltamethrin, malathion and phosphine fumigation alone or in combination. Several researchers were interested in the physical struggles, ionizing radiation from gamma source of cobalt-60 and resistant varieties of grain in the case of rice, wheat or corn. Also, parasites, pathogens and predators (Trichogramma spp, Blattisocius tarsalis, Cotesia ruficrus, Pteromalus cerealella and Bracon hebetor) were experienced as biological insecticide on different developmental stages of S. cerealella. Treatments based on powders, extracts or cooking oils of plants such insecticides like Cymbopogon citratus, Tagetus erecta, Chenopodium ambrosioides, Azadirachta indica, Zanthoxylum zanthoxyloides and Khaya ivorensisaux were studied. However, unlike other pest insects like Sitophilus spp, Rhyzopertha dominica, Prostephanus truncatus, Tribolium sp or even Callosobruchus sp, little work is done in the field of fight against Angoumois grain moth.through volatile extracts. Conclusion : Essential oils from aromatic plants of Benin could effectively control populations of S. cerealella in the conservation of stocks of rice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
