This article considers characteristics of the trophic structure of ins
ects arising in the process of colonization of sowings of soy monocult
ure. It is shown that the community's trophic structure preserves its
stability (in spite of a constant turnover of species) during the grea
ter part of the vegetation period. The community's trophic structure i
s also unchanged in different years, despite sharp variations in absol
ute number and species composition.
