“…The reason for the slightly higher reported severity score in 2010/2011 cropping season compared to 2009/ 2010 cropping season could be due to differences in the rainfall pattern between the two cropping seasons. The rains came earlier during the 2009/2010 cropping season which kill most of the grasshoppers as rain is one of the natural mo rtality factor for grasshoppers [16]. This early rain also causes the cassava plant to recover quickly fro m the defoliat ion effect of the grasshoppers.…”

“…Les observations ont montré que l'infection à E. grylli est un facteur important de mortalité des larves du criquet Z. variegatus comme l'avaient rapporté par ailleurs Chapman & Page (1979). Les taux d'infection naturelle à E. grylli sont plus importants, comparés à ceux dus à Metarhizium flavoviride sur les acridiens dans la même zone d'étude estimés en moyenne entre 1,8 et 2,9% selon le site (Shah et al, 1994).…”

“…Among them, the cosmopolitan fungus Entomophaga grylli (Fresenius) A. Batko, 1964 is famous for causing spectacular natural epizootics on different continents: in Africa (Skaife 1925, Lepesme 1938, Chapman & Page 1979, Australia (Milner 1978), North America (Treherne & Buckell 1924, Walton & Fenton 1939, Pickford & Riegert 1964, MacLeod & Müller-Kögler 1973, McDaniel & Bohls 1984, Erlandson et al 1988, Valovage et al 1984, Valovage & Nelson 1990, Central America (Sánchez-Pena 2000) and South America (Marchionatto 1934, Fresa 1971, Méndez-Sanchéz et al 2009, Pelizza et al 2010. The insects infected by E. grylli exhibit distinctive and unique signs at the advanced stages of the disease.…”
