CARDENAS, Regla M; ORTIZ, R  y  RODRIGUEZ, Odile. Daños en germoplasma de cebada (Hordeum vulgare Lin.) producidos por Rhyzoperta dominica FABRICIUS. cultrop [online]. 2009, vol.30, n.2, pp. 00-00. ISSN 0258-5936.

Quantitative damages caused by stored pests are vitally important to seeds destined for investigation, since there are generally very small amounts. The study was carried out in seeds from 96 Syrian barley lines preserved for six months at 15 + 2oC, with the objective of knowing this sort of losses provoked by Rhyzoperta dominica F.; thus, weight reduction (g) was considered, 1000-grain weight (PMG) was determined, the number of adult insects in 1000 grains (NAMG) was estimated and attack index (IA) was also calculated. Results showed that 12 lines were damaged by R. dominica, with an average weight (g) loss of 18 %; the lines studied showed a low PMG (32.38 g), whereas the estimated NAMG was of 31.25 and IA of 3.17 %.
