Summary: | The Larger Grain Borer (LGB), Prostephanus truncatus (Horn), is an
exotic pest of stored maize and cassava which first appeared in Kenya
in 1983. Studies using pheromone traps show that LGB is widespread in
the natural vegetation in Tsavo National Park. Experiments to determine
alternative hosts of the LGB have shown it capable of feeding and
breeding in 16 tree species in the families Leguminoseae, Burseraceae
and Anacardiaceae. Some of these species are of significance to
agroforestry. Within a tree, breeding success of LGB is dependent upon
the wood's age, and its moisture content. The possible role of
alternative host plants in influencing LGB infestations in stored maize
is discussed. |
