In the years 1995-1997 the effect of tansy phacelia and white mustard sown
between rows of three cultivars of Pisum sativum L. on the
occurrence of pea pests was estimated. In the case of pea weevils (Sitona
sp.) its notches were counted in the four-leaf phase. For the remaining
pests the presence of pea aphid (Acyrthosiphon pisum) on the plants, of
pea thrips (Kakothrips robustus) on flowers and
infestation of pea pods by the pea moth (Laspeyresia nigricana),
and pea seeds by the pea beetle (Bruchus pisorum) were observed.
It was found that intercropping of pea with tansy phacelia and white mustard had the effect of decreasing
the pea thrips population in comparison with monoculture. A similar effect
was observed for feeding of the pea weevil on the leaves, although the
differences were less noticeable. Intercropping had no impact on
the occurrence of the pea aphid, pea moth, and pea beetle.
