In 1987-1988 the effectiveness of onion seedling protection against Lilioceris
merdigera L., by the use of trap plots was studied. Three cultivars of
onion sets were tested as "trap plants". The protective zone of
onion sets applied around onions grown from seed was found to diminish the
number of laid eggs as well as feeding individuals of onion beetle by 50%.
No significant differences in the attractiveness (to Lilioceris) of
three local cultivars of onion sets (Wolska, Rawska, Czerniakowska)
cultivated to protect onion grown from seed were observed.
