Abstract
This paper describes common insect blighters in forage alfalfa in Bulgaria and their seasonal dynamics. the strategy of sweeping with the zoology internet was used. The degree of infestation (attack) of Otiorrhynchus ligustici was established by taking soil monoliths. the foremost common insect pests of alfalfa from Coleoptera are Hypera postica, Sitona spp., Apion seniculus, and Otiorrhynchus ligustici. the following species belongs to orders animal order and animal order. Therioaphis maculata was the most harmful metal money, followed by Acyrthosiphon genus Pisum from Aphidodea, still Adelphocoris lineolatus and genus Lygus rugulipennis (Hemiptera – Heteroptera). Economic importance species from Hemiptera: Fulgorormorpha and Cicadomorpha were Empoasca pteridis and Agallia ribauti, still Thrips tabaci and T. atratus (order Thysanoptera). Apion seniculus is reportable for the primary time in our country as harmful species in alfalfa. the most insect pests, betting on the order to that they belong, were found in high numbers through the various regrowth of alfalfa vegetation amount. The determination of the population dynamics of economically vital blighter species within the alfalfa adult for forage, helps verify the foremost applicable time for management and management.
