The influence of weed infestation and pea (Pisum sativum (Linn.)) cropping system on the beneficial and harmful entomofauna

The experiment was carried out in the conventional and organic experimental fields of Institute Agriculture - Karnobat, period 2019 2022. aim to study influence weed infestation cropping system pea (Pisum sativum (Linn.)) on beneficial harmful entomofauna. Six seven species insects from families three orders were found damage farming, respectively. Their density higher farming. most economically important widespread pest both types aphid Acyrthosiphon pisum (Harris, 1776). Of insects, thirteen eleven eight five orders. Greater diversity numbers observed organically grown during all four years study. absence herbicide treatment farming presence more blooming vegetation stimulate multiplication entomofauna, regulating population aphids pea. correlations between entomofauna have been demonstrated.
