520 | _aThe susceptibility of maize germplasm from CIMMYT-Mexico, Malawi and Zimbabwe-to attack by the maize weevil, Sitophilus zeamais (Motsch.) was investigated under controlled temperature (28 deg C) and r.h. (70-75). An index of susceptibility (I), derived the numbers of F1 progeny and the mean development period was used as the basis for measurement of the susceptibility. The indices of susceptibility of the CIMMYT germplasm ranged from 9.25 for Rattray Arnold (I) 8149 to 14.48 for Poza Rica 7737. Of the 17 collections of Malawi local maize evaluated MLM no. 20 was the least susceptible (I=10.72), while MLM no. 24 was most susceptible (I=13.25). The | ||
