A behavioural study to help clarify how undersowing with clover affects host‐plant selection by pest insects of brassica crops

Abstract: Laboratory and field‐cage tests were done to determine how undersowing brassica plants (Brassica oleraceae L. and B. rapa L.) (Cruciferae) with subterranean clover (Trifolium subterraneum L.) (Papilionaceae) affected host‐plant selection by eight pest insect species of brassica crops. The pest species tested were Pieris rapae (Lepidoptera: Pieridae) (the small white butterfly), Pieris brassicae (Lepidoptera: Pieridae) (the large white butterfly), Delia radicum (Diptera: Anthomyiidae) (the cabbage root fly), Ph… Show more

“…To prevent this happening, the test plants in the experiments of Finch & Kienegger (1997) were left in their pots throughout the test periods. As the effects of the clover were still evident and often within minutes of starting an experiment (Finch & Kienegger, 1997), a generic mechanism based on the non-host plants (here clover) causing physiological changes in the host plants (Theunissen, 1994) cannot be supported.…”

“…It is also established that diversification might influence agroecosystems through various modes of action. Diversification can impede pests' host plant finding behaviour (Root, 1973;Wratten & van Emden, 1995;Finch & Kienegger, 1997;Finch & Collier, 2000), and it can affect crop yields directly ( Theunissen & den Ouden, 1980;Tukahirwa & Coaker, 1982). Diversification might also impinge on pests indirectly, through boosting their natural enemies, such as spiders.…”
