A socio-economic study was executed in South East Niger to determine the conditions under which a novel mycopesticide based on the fungus Metarhizium flavoviride could be introduced for locust and grasshopper control as a possible alternative reducing the use of synthetic chemicals. From the inte...

Pratiques paysannes et utilisation potentielle de Metarhizium flavoviride Gams and Rozsypal en lutte antiacridienne au Niger
1 Thermal behaviour of the variegated grasshopper, Zonocerus variegatus, was investigated in the humid tropical zone of southern Benin, west Africa, in the dry seasons of 1996 and 1998. In 1998, investigations included studies of a population of grasshoppers sprayed with an oil‐based formulation ...

Thermal ecology of Zonocerus variegatus and its effect on biocontrol using pathogens
The life cycle and development of Zonocerus variegatus (variegated grasshopper) from southern Benin was studied at the International Institute of Tropical Agriculture (IITA) Benin Station, from March 1992 to August 1994. Hoppers of the 1st to the 5th stage were collected from uncultivated fields ...

Farmers of two villages in Mono province, Benin, in collaboration with researchers of the biological control of locusts and grasshoppers program (LUBILOSA) at IITA, developed a use and marketing strategy for the biopesticide Green Muscle, an oil-based formulation of the entomopathogenic fungus Me...

Farmer participatory development of a control strategy for the variegated grasshopper with a biopesticide in the northern Mono, Benin.
The prospects for development of microbial control in West Africa are bright, with many stakeholders in plant protection both within and beyond the region becoming increasingly interested. To date however, on the West African market, there are only two microbial products available, and many oppor...
Locusts are the most feared pests of farmers living around the world’s major deserts. Millions of liters of environmentally damaging pesticides are sprayed over vast areas of land to control them and their grasshopper cousins. This paper tells the life history of the LUBILOSA (Lutte Biologique co...

Medium-scale experimental field applications of two grasshopper and locust control agents, the mycoinsecticide Metarhizium anisopliae (flavoviride) var. acridum (Deuteromycotina: Hyphomycetes) and the organophosphate fenitrothion, were carried out in August 1996 in Maı̈ne Soroa, Niger. The object...

An assessment of the impact of biological and chemical grasshopper control agents on grounddwelling arthropods in Niger, based on presence/absence sampling
Control of grasshoppers and locusts has traditionally relied on synthetic insecticides, and for emergency situations this is unlikely to change. However, a growing awareness of the environmental issues associated with acridid control as well as the high costs of emergency control are expanding th...
