Studiul legăturilor trofice și voracitatea prădătorului Amphiareus obscuriceps (Popp.) pe gazde alternative

Abstract

The paper presents the results of the study of the natural and laboratory trophic links of the invasive predatory bug species Amphiareus obscuriceps found in the trap belts intended to study the winter reserve of plum crop pests. The predator was offered eggs of different stages of embryonic development of whiteflies Aleyrodes proletella, A. singularis, obtained from the plum plantation; Acanthoscelides obtectus and Galleria mellonella eggs obtained under laboratory conditions. It was determined that the predator can suck in one day on average 40.2 eggs of G. mellonella, 26.1 eggs in the late stage of embryogenesis and 11.7 eggs of one day of A. singularis and 9.3 eggs of A. obtectus.
