Experiences of integrated pest management in Cuba. Study of cases

Abstract

The aim of the work was to evaluate the effect of integrated management measures on the key pests of tobacco, soybeans and sesame. Three experiments were developed, the first had three treatments: T1. 12 rows of tobacco + 1 row of sorghum + 1 row of sunflower, with applications of B. thuringiensis; T2: Monoculture tobacco with applications of insecticides; T3: Absolute control. The soybean and sesame experiments had two treatments each, respectively, Direct Sowing (T1) and Conventional Tillage (T2) and distance between rows of 0.60 m (T1) and 0.80 m (T2). In the three experiments the key pests were evaluated by direct observation according to the methodology described for each case. Polyculture, direct sowing and the shorter distance between rows maintained lower population levels of the key pests in each crop.
