Summary/Abstract: Pea (Pisum sativum L.) is a major grain legume crop in Bulgaria. Pea yields are determined by a number of abiotic and biotic factors, including diseases and pests. The economically important and widespread pests in pea in our country are: Aphis fabae, Acyrthosiphon pisi, Kakothrips robustus, Cydia nigricana, Laspeyresia dorsana, Bruchus pisorum, Contarinia pisi and Tychius quinquepunctatus. According to the integrated pest management system, the control of the insects populations have to combine all known methods in the most appropriate way so as to maintain the population density of the most important insects below the economic thresholds harmfulness. The chemical method should be applied when insect density is over economic thresholds harmfulness with registered insecticides
