The incidence of the corn leafhopper decreases in crops in Argentina and Uruguay

The National Network of Monitoring Traps in Argentina for the corn leafhopper (Dalbulus maidis), the small insect that transmits the crop stunting disease that caused huge production losses last season, announced the results of its sixth survey --carried out in that country but also in Uruguay-- and there is good news: the pest population has again decreased in most of the sites studied. In this case, the adult leafhoppers captured between October 4 and 21 in adhesive chromatic traps in 429 locations in Argentina were counted, distributed in the northwest, northeast, the Litoral region, the central north and the central south. In addition, 19 locations in Uruguay were incorporated. The Clarín newspaper report indicates that in all regions, the localities that recorded D. maidis capture were represented by the lowest category (1 to 4 D. maidis adults per trap), except for the NOA, which had a slight increase in localities corresponding to the category with 5 to 20 D. maidis adults ...
