Report 1980

Autor: Cardona, C.

Studies on the biology and damage caused by bean pests Diabrotica balteata and Cerotoma facialis have been conducted at CIAT since 1977. The biology of the 2 species is similar in many aspects. Life cycle is as follows: eggs, 6-7 days; 1st larval instar, 3-4 days; 2nd instar, 2-3 days; and 3rd in...

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...

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...

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...

Significant advances in increasing tolerance to the leafhopper Empoasca kraemeri Ross & Moore in common bean have been obtained using a new breeding scheme where yield under leafhopper attack is the principal selection criterion in the evaluation of progenies. However, to further refine this bree...

The bean weevil Acanthoscelides obtectus, is an important storage pest of common beans in Latin America and Africa. A few wild bean accessions from Mexico have been identified as highly resistant to the weevil. One accession, G 12952, was crossed to two susceptible bean cultivars differing in see...

Four different types of arcelin, a protein that plays an important role in resistance to bruchids such as Zabrotes subfasciatus, were identified in wild accessions of Phaseolus vulgaris. Isogenic lines with cultivated black- (Porrillo 70) and white- (Sanilac) seeded parents were obtained by norma...
