Distribution and biology of invasive species of pea weevil (Bruchus pisorum).
A review on ecology, biology, and distribution of pea weevil and its main food plant, Pisum sativum, and the influence of abiotic, biotic and anthropogenic factors on the invasive process and phytosanitary condition of pea crops in Russia is presented. The main stages and areas of cultivation of pea and invasion of pea weevil from their primary habitat in Western Asia are traced. The factors and their causes are considered. In Russia, the economic importance of pea weevil has increased since the mid-1980s, which coincided with the spread of no-till and minimum tillage, climate warming, and a decrease in the size of farms. There was an expansion of its spread in the eastern and northeastern directions. Isolated foci of high density and harmfulness of the weevil was formed in Altai Territory in 1999. Pea weevil was registered in Tatarstan and Bashkiria in 1980-1983 and in Kemerovo and Tomsk oblasts in 2010-2012. From 2008 to 2018, there was an expansion of the range of this invader to the north, including Arkhangelsk oblast.
