The results of 2-year research on species content determination, seasonal dynamics of population of dominated pest species of lupine (Lupinus angustifolius) agrocoenosis were presented. The research was realized in the conditions of the Republic of Belarus in 2010-2011. As a result of realized research it was revealed that formed entomocomplex in blue lupine agrocoenosis included 30 insects species, belonging to 23 genus and 17 families. The analysis of entomofauna trophic structure has shown, that phytophages made 64%, entomophages – 36%. It was determined, that at stages germination, seedlings crops were colonized by click beetles and tubercular weevil, at stage stem formation – aphids, thrips. Thrips dominated among the pests. The most numerous one was thrips Frankliniella intonsa Tribom, which took more than 70% among other species of phytophages according to occurrence.
