Field samples of beans on subsistence farms in Ntchisi, central Malawi, showed a correlation between the incidence of Fusarium solani f. sp. phaseoli and the presence of bean fly (Ophiomyia complex) puparia. Exclusion experiments in the field and greenhouse measured the rate of F. s. phaseoli infection in beans subjected to and protected from bean fly attack. Results indicated that F. s. phaseoli infection was significantly higher in plants exposed to bean fly attack than in those protected from bean flies (.)
