Abstract
The effect of various numbers of adult insects and larvae of Lilioceris merdigera, feeding in insulators, on the yield of three cultivars of onion grown seed and from sets, was investigated in 2-year experiment. It was found that greater adverse effects were brought about by adults than by the same number of larvae. The greatest damage to leaves (50 percent on onions grown from sets and even 70 percent on seedlings) was found in the case of the feeding of four adult insects or two adult forms and 2 larvae
