En Cruz das Almas, BA, Brasil, se estudio el efecto del nivel del dano causado por el gusano cachon y de la edad del cultivo de yuca en el momento del ataque en la productividad de raices. Se uso un diseno de bloques completos al azar con 6 tratamientos y 4 repeticiones. La defoliacion de plantas de 6 meses de edad redujo el rendimiento en 27.5 por ciento . La defoliacion solo afecto el porcentaje de almidon en plantas de 2 y 4 meses de edad. (RA-CIAT) The effect of the level of damage caused by the cassava hornworm and of the age of the cassava crop at the time of the attack on root yield was studied at Cruz das Almas, BA, Brazil. A randomized complete block design was used with 6 treatments and 4 replications. Defoliation of 6-mo.-old plants reduced root yield by 27.5 percent. Defoliation affected only the percentage of starch in 2- and 4-mo.-old plants. (AS)
