Effectiveness of Application of Parasitic Entomophages against Plant Bits in Vegetable Agrobiotensenosis

Abstract

In the management of the number of sucking pests of vegetable crops during scientific studies,
the composition of the species Lysiphlebus fabarum Marsch of the family (Aphidiidae) and their biological
effectiveness against plant lice have been widely studied and scientifically based. The research was
conducted mainly in the districts of Tashkent and Syrdarya regions, in areas infested with vegetable lice, as
well as in research centers for biological protection of plants. Aphis craccovora Koch, the most common
primary of plant lice; Aphis gossypii Glow; Rhopalosiphum nymphaeae, Brevicoryne brassicae species and
their effective parasite entomophagous Lysiphlebus fabarum Marsch species infestation rates were studied
