weevils (Otiorhynchus sulcatus) are a major problem in
horticulture because not only can a severe infestation can be quite
devastating it is also extremely hard to protect plants against
adults are nearly all female and reproduce partheno-genically.
The presence of adult vine weevils can be determined by the
removal of irregular notches from the margins of the leaves.
the bites that they take from the leaves do very little harm it is
the fact that they are present and may have laid their eggs by the
roots of plants that gives major cause for concern.
a plant suddenly dies and appears to have no roots, this is the work
of the larvae.
