J. Kroschel et al., HERBIVORES OF STRIGA-HERMONTHICA IN NORTHERN GHANA AND APPROACHES TO THEIR USE AS BIOCONTROL AGENTS, Biocontrol science and technology, 5(2), 1995, pp. 163-164
A survey of herbivores of Striga hermonthica Del. Benth., a root paras
ite of cereal crops, was conducted in northern Ghana in 1992. Smicrony
x umbrinus Hustache (Coleoptera: Curculionidae) and Junonia orithya L.
(Lepidoptera: Nymphalidae) were found to attack S. hermonthica in all
areas surveyed. Preliminary observations indicate that these two inse
cts have a great potential to cause damage. In the Shinyanga region of
Tanzania, Malawi and the middle-west of Madagascar, investigations re
vealed that only J. orithya is common in all areas surveyed in contras
t to the situation in northern Ghana.
