In: Report to the Minister of Agriculture of the Ibaban, Ibaban, Republic of Zaire: IITA Mimeograph. Three NKWE treatments at weekly intervals protected cassava against established early instar nymphs; however, some phytotoxicity was observed. The parasitoid attacks the second and third instar stages of the cassava mealybug. This so-called 'biological control' endeavor was awarded with the 1995 World Food Prize being handed to Swiss entomologist Hans Rudolf Herren. In: Yaninek JS, Herren HR, eds.

Use of manure or other fertilizers can result in a reduction in the mealybug population because improved nutrition results in the production of larger parasitoid wasps with higher fertility levels (Schulthess et al., 1997). It was introduced to Nigeria in 1981 and is now established in at least 26 African countries (Ganga, 1984; Herren et al., 1987b; Korang-Amoakoh et al., 1987; Biassangama et al., 1988; Neuenschwander and Herren, 1988; Neuenschwander et al., 1989a, 1989b; Boussienguet et al., 1991; Hennessey et al., 1990; Herren and Neuenschwander, 1991; Neuenschwander and Zweigert, 1994).
