Effects of intercropping on a population of sweet potato weevil, Cylas formicarius (F.) Coleoptera curculionidae
1992
Yaku, A. | Hill, S.B. | Chiasson, H.
The effect of intercropping on a weevil population was investigated. Fewer weevils were found on intercropped sweet potato and corn (2weevils/kg infected tubers) than in monoculture sweet potato (37 weevils/kg). The percentage of damaged tubers followed this trend ranging from 2.6 per cent to 14 per cent in intercropped potato to 21.9 per cent under monoculture. The intercropped sweet potato had, however, lower yields from 0.8t/ha to 2.9t/ha compared to 7.0t/ha under monoculture
