The African rice grasshopper, Hieroglyphus daganensis is a medium-sized grasshopper species found in the Sahel region. Although not called a locust in English, this species shows gregarious behaviour and some morphological change (phase polymorphism) on crowding and may become a moderately important pest species for small-holder farmers in the region.

Adults

The overall colour of adult insects is usually green, with a finely dotted shiny integument. Antennae are longer than the head and pronotum together. The pronotum is cylindrical, with three deep and wide sulci (grooves) crossing the dorsum.

Hoppers

The colour of immature insects may vary depending on their phase: in the illustration above, during a particularly fertile year, dense populations of H. daganensis showed a distinct blackening in certain areas of cuticle.

Outbreaks and Control

Outbreaks are frequent in Sahelian countries such as Senegal, Mauritania, Burkina Faso, Mali, Niger and Benin.

A biological pesticide product called 'Green Muscle' is based on the entomopathogenic fungus (Metarhizium acridum) is now available (see desert locust). Early demonstrations of efficacy took place in northern Benin, with field tests by the LUBILOSA Programme on H. daganensis.
