La presente publicación tiene como objetivo brindar información acerca de una importante enfermedad que afecta al cultivo del peral y que, desde hace algunos años ha sido detectada en nuestro país. El decaimiento del peral probablemente haya estado entre nosotros desde hace mucho tiempo, pero, es en estos últimos años que cobró importancia debido a algunos cambios introducidos en el cultivo y a la relevancia que ha cobrado su vector, la psila.

ABSTRACT. A system of nine censored Engel curve equations was estimated for Hispanic households in the U.S.:grains, vegetables, fruits, milk, meat, legumes, fats, sugar and beverages. Income and household size elasticities, with respective confidence intervals, are reported and the results compared with other ethnic groups in the U.S.

ABSTRACT. Hispanics are the fastest growing ethnic community in the United States. By 2010, Hispanics will comprise 15,5% of the U.S. population. Moreover, Hispanic's buying power, estimated at %350 billion, grew at a compound annual rate of 7,5% between 1990-97. The primary reasons why the Hispanic market is the leading growth sector for food in the U.S. are income growth, and high birth and immigration rates.

The primary objective of this thesis was to analyze food expenditure patterns of the Hispanic population in the United States during the period 1994-1996. Two specific studies were conducted to accomplish this objective. In the first study, the expenditure patterns for total food (TF), food eaten at home (FAH) and food eaten away from home (FAFH) were examined.
