The general objectives of CIAT's bean entomology program are mentioned. The 1st priority has been given to var. resistance as an ideal pest control method. At CIAT's headquarters (Palmira, Colombia), studies are conducted on Empoasca kraemeri, mites, and storage insects; var. resistance to Apion ...

Se mencionan los objetivos generales del programa de entomologia de frijol del CIAT. La mayor prioridad se ha dado a la resistencia var. como metodo ideal de control de plagas. En la sede principal del CIAT (Palmira, Colombia) se adelantan estudios con Empoasca kraemeri, acaros e insectos del fri...

The biology of pod-attacking insect pests of beans (Apion godmani, Epinotia aporema, Maruca testulalis, and Heliothis spp.) is briefly described. Cultural and chemical control measures are indicated. Some biological control measures are indicated for the case of Heliothis. (CIAT)

Se describen brevemente la biologia de los insectos plaga (Apion godmani, Epinotia aporema, Maruca testulalis, Heliothis spp.) que atacan las vainas del frijol. Se indican medidas de control cultural y quimico. En el caso de Heliothis, se indican algunas medidas de control biologico. (CIAT)

Pests may affect bean production, before and after harvest. Those that attack bean seedlings are the seed corn maggot which causes poor germination and deformed seedlings. The most common genera of cutworms include Agrotis, Feltia, and Spodoptera; white grubs and crickets also attack the seedling...

The biology, damage caused, and control (cultural, chemical, and var. resistance) of the following insect pests attacking bean plant foliage are described: chrysomelids, Empoasca kraemeri, Epilachna varivestis, Trichoplusia ni, Bemisia tabaci, aphids, Tetranychus spp. Polyphagotarsonemus latus, A...

Se describen la biologia, el dano que ocasionan y el control (cultural, quimico y resistencia var.) de los insectos plaga que atacan el follaje de las plantas de frijol: crisomelidos, Empoasca kraemeri, Epilachna varivestis, Trichoplusia ni, Bemisia tabaci, Afidos, Tetranychus spp., Polyphagotars...

Las plagas pueden afectar la produccion de frijol, antes y despues de la cosecha; las perdidas varian de una region a otra, debido a las diferencias que existen en las fechas de siembra, var, y practicas culturales. (1) Entre las que atacan el frijol: mosca de la semilla (Hylemya cilicrura), la c...

Obtaining insect-resistant var. involves (1) searching for sources of resistance, (2) reconfirming levels of resistance, (3) hybriding, and (4) selecting resistant progenies. Sources of resistance can be obtained from native var., introduced foreign var., wild (uncultivated) materials, and materi...

La obtencion de var. resistentes a insectos comprende 1) la busqueda de fuentes de resistencia, 2) la reconfirmacion de los niveles de resistencia, 3) la hibridacion y 4) la seleccion de las progenies resistentes. Las fuentes de resistencia se pueden obtener a partir de var. criollas, var. forane...
