Comparative Spatial Distribution of Sucking Insect-Pest-Complex in Summer and Monsoon Cowpea [Vigna unguiculata (L.) Walp.]

Background: Pulse crops are known as an important dietary source of proteins for a major part the vegetarian population across globe; especially in India. Legume help restoration soil fertility through symbiotic nitrogen fixation. Spatial distribution is aspect it interprets interaction between individuals species and their habitat. The biological reason aggregation highly unpredictable depends on behavioural pattern insect; therefore, spatial accounts informative description organisms. Methods: In order to study sucking pests cowpea, field trial was laid out during Zaid Kharif separately at Instructional Farm Rajasthan College Agriculture, Udaipur 2019 2020. Cowpea variety Pusa Komal cultivated 6 plots each 3 m x with row plant spacing 50 cm 10 cm, respectively. Different were used determine insect fauna associated cowpea summer monsoon season. Result: most pest complex contagious both respective seasons. All positive IDM (index clumping) values confirmed clumping mean crowding index more than unity, indicated clumped interaction.
