The results of an investigation of some factors in the effectiveness of egg-parasites of the gipsy moth

, : The results of an investigation of some factors in the effectiveness of egg-parasites of the gipsy moth. Zast. Bilja, Belgrade, 14: 76, 693-699

In view of local variations in Yugoslavia in the degree of parasitism of the egg-masses of Lymantria dispar (L.) by Anastatus disparis Ruschka, investigations were made on the relation between the percentage of eggs parasitized and the thickness of the egg-mass. Ten egg-masses from the island of Hvar were each divided into four layers.

Randomised controlled trials (RCT) are highly influential upon medical decisions. Thus RCTs must not distort the truth.
