Observations on white grubs affecting sugar cane at the Juba Sugar Project, south-western Somalia, in the 1980s, and implications for their management
Insects 4 (2), 241-272
Abstract: The authors made two visits to the Juba Sugar Project in south-west Somalia, at the beginning of the minor rains in October 1986, and at the beginning of the main rains in March 1987. Observations were made on morphospecies of scarabaeid white grub larvae, the adults, and the two associated for the key economic species, Cochliotis melolonthoides and Brachylepis werneri. Sampling larvae and adults by digging soil quadrats and adults by light trapping gave useful information on their biology and phenology. Sampling methods were evaluated and economic thresholds were extrapolated based on earlier work. Natural enemies were surveyed, and entomopathogenic nematodes and a cordyceps fungus (Ophiocordyceps barnesii) were considered to have potential to be used as biological control interventions.
