- Description
- Smith's (personal communication) work in a continuous, commercial cabbage-growing area near Grahamstown showed that parasitism of diamondback moth averaged over 60% and could reach 100%. In many parts of the world cabbage crops are not under continuous cultivation, and periodic cropping Systems may demonstrate différent patterns of parasitism, especially in disrupted, patchy subsistence crops. Cabbage (Brassica oleracea) is the most commonly grown cruciferous crop in subsistence gardens in the suburbs of Grahamstown East. The subsistence farmers' crops are considered patchy because the cabbages are grown in small and relatively widely separated plots. Thèse gardens provided an opportunity to follow Talekar and Shelton's (1993) suggestion to investigate the population dynamics of P. xylostella (a useful model pest) and its rate of parasitism on cabbages of subsistence farmers where commercial pesticides are used less.
