Movement and feeding activity of adult pea leaf weevil, Sitona lineatus L. in an oat–broadbean diculture
Published online by Cambridge University Press: 19 September 2011
Abstract
This paper briefly discusses insect pest responses in mixed crop stands, their peculiarities and possible crop protection advantages. Results on the effects of a bean–oat diculture on the movements and feeding activity of the adult pea leaf weevil, Sitona lineatus L. are presented and discussed. Mixtures of these crops were found to significantly reduce the amount of notching of the bean leaflets by the weevil and weevil relative populations are compared to the sole bean crops, and to increase emigration from the more diverse plots.
