Since 1998, PPRI Honorary Research Associate and locust consultant based in Pretoria. Total of 49 years field experience in locust and grasshopper research in Southern and Central Africa and Madagascar.

2. Experience

Known for introducing innovative field management technologies for locust control in Southern Africa, compatible with global priorities. Has field experience with 5 locusts (ie. brown locust, Locustana pardalina; red locust, Nomadacris septemfasciata; African migratory locust, Locusta migratoria migratorioides; Madagascar migratory locust, Locusta m. capito; and, lastly, southern African desert locust, Schistocerca gregaria flaviventris). Also a grasshopper expert having described numerous new genera and species in the arid regions of Southern Africa.

Has worked in the field in 13 different African countries and additionally in Madagascar. 40 publications to date, encompassing taxonomy, biology, ecology, chemical control, product evaluation, alternative control strategies (baiting & use of bio-insecticides), mapping and forecasting locust outbreaks. Technology transfer and dissemination of locust management information carried out on behalf of FAO, SADC/SARCCUS, USAID, GTZ and DANIDA international organisations, serving as training facilitator in Botswana, Mozambique and Namibia. Has carried out consultancies for Botswana, Namibia, South African and Malagasy Governments together with numerous multi-national Chemical Companies. Earlier experience for doctoral project included biological control and integrated pest management of wheat aphids in cereal crops in the Free State Province.

3. Service Record

Served as founder member on the Southern African migratory pest control subcommittee of SADC/SARCCUS (1970-1997). Associate Member Transvaal Museum (1987- ). Since 1995 serving on FAO Pesticide Referee Group Meetings in Rome.
