NOCIVIDAD DE CRISOMÉLIDOS SOBRE PLANTAS DE SOYA EN CONDICIONES DE LABORATORIO E INVERNADERO.

The foliate consumption per day of the most abundant species of the chrysomelidae complex present in soybean was determined under laboratory conditions. The attack repercussion of these insects on growth and productivity indicators (plant height, number of trifoliate leaves and vegetables per plant, foliate dry and fresh weight of vegetables and the total of the plant) of the varieties Cubasoy-23, Incasoy-24 and Incasoy-27 was studied in mesh houses. Also, absolute growth and relative rate, foliage and specific area and harmfulness coefficient for the grain weight were determined. Maecolaspis brunnea was the species consuming more foliate per day (21.33 cm²). Damages caused by the chrysomelidae complex significantly affected growth and development indicators, as well as yield components in spite of crop recovery capacity. Under greenhouse conditions, the variety CS 23 showed the most unfavourable behaviour to the attack of these insects. [ABSTRACT FROM AUTHOR]
