NEW CONTRIBUTION CONCERNING THE MASS REARING OF TANYMECUS DILATICOLLIS GYLL (COLEOPTERA: CURCULIONIDAE) UNDER CONTROLLED CONDITIONS

Abstract

Controlled growth in the laboratory of some species of insect’s are justified both scientifically and practically. Due to the economic importance that the corn crop pest Tanymecus dilaticollis Gyll. (Coleoptera: Curculionidae) had in Romania like the main pest of maize crops we tried to obtain successive generations under environment controlled of the insect mentioned. In this paper we aim to improve the efficiency of the multiplication of the species with respect to two aspects: attending larval and multiplication high efficiency. The coefficient value of 20, 90 obtained by us indicate a considerable increase in performance compared to previous attempts multiplication thus increasing your chances of recovery of this method of mass multiplication.
