Seasonal variation of aphids on cabbage
Raw field data for aphid and predator (Syrphid, spiders, and coccinellids) densities on cabbage, and weather data in two agroecological zones of Ghana, collected over two years for five cropping seasons.
Steps to reproduce
Data was collected on field-grown cabbage weekly after two weeks of transplanting, till when cabbages were matured. The destructive sampling method according to Hughes, 1963 was adopted by randomly sampling the third, fourth, and fifth expanded leaves of 20 randomly selected cabbage plants. Aphids and predators present were visually identified, counted, and recorded.
