| description | This audiotutorial unit (cassette, printed script, 70 color slides, study guide, self-evaluation test), prepared by the Communications Support Unit at CIAT, is available for use with a manually or automatically synchronized slide projector/cassette tape recorder. Each unit is available from the Distribution Office at a cost of US$ 50; photocopies of the study guide alone can be obtained from the Cassava Information Center. Data are given on the biology of the hornworm, its economic importance and possible methods of control. Integrated control of Erinnyis ello should begin immediately after the previous harvest, applying cultural practices such as plowing between rows and weed control. Biological control should be continuous even though severe attacks do not occur; a good option is the combined use of egg parasites (Trichogramma spp.) with larval predators (Polistes sp.) and parasites (Apanteles sp. and Euplecirus sp.). The farmer should keep constant track of the no. of parasitized and nonparasitized eggs, especially in young plantations. If the no. of nonparasitized eggs increases, there will be an increased no. of larvae. In this case Trichogramma wasps should be released in the field (10-20 (in.)2/ha), or the crop should be sprayed with Bacillus thuringiensis (350-400 g/ha). Chemical control should be avoided since its continued use wiil upset the balance between the pest population, the natural enemies and the fauna in general, intensifying later attacks. Therefore, chemical contTrol should be used only when there is a very severe attack (high larval populations/plant) and when the plants are young (up to 6 mo). (CIAT) |

(CIAT) Esta unidad audiotutorial (cinta magnetofonica, guion, 70 transparencias a color, guia de estudio, auto-evaluacion), preparada por la Unidad de Comunicaciones del CIAT, esta disponible para usarla en sincronizacion automatica o manual por medio de un proyector de transparencias o una grabadora de cassettes. Cada unidad esta disponible en la Oficina de Distribucion a un costo de US$ 50; en el Centro de Informacion sobre Yuca solamente pueden solicitarse fotocopias de la guia de estudio. Se informa sobre la biologia del gusano cachon, su importancia economica y posibles metodos de control. El control integrado de Erinnyis ello debe iniciarse inmediatamente despues de la cosecha anterior, aplicando practicas culturales tales como arar en hileras y control de malezas. El control biologico debe realizarse continuamente aunque no ocurran ataques severos; una buena opcion es la utilizacion combinada de los parasitos de huevos (Trichogramma spp.) con los predatores de larvas (Polistes sp.) y parasitos (Apanteles sp. y Euplectrus sp.). El agricultor debe efectuar constante conteo del no. de huevos parasitados y no parasitados, especialmente en plantaciones jovenes. Si el no. de huevos no parasitados aumenta, habra un incremento en el no. de larvas. En este caso, las avispas Trichogramma spp. se deben liberar en el campo (10-20 pul2/ha) o realizar una aspersion con Bacillus thuringiensis (350-400 g/ha). El control quimico debe evitarse ya que su uso continuo provoca el desequilibrio entre la poblacion de la plaga, los enemigos naturales y la fauna en general, intensificando ataques posteriores. Por lo tanto, el control quimico debe realizarse solo cuando hay un ataque muy severo (altas poblaciones de larvas/planta) y cuando las plantas son jovenes (hasta los 6 meses).
