Abstract
Four particle sizes of Atlas sorghum grain were utilized to observe the effect of the media on development of the weevil Sitoph ilus zca-mais Motschulsky. The largest number of adults emerged from whole sorghum kernels and the least number from the coarsely ground sorghum grain. Newly developed adults were observed in the finely ground medium. Survival of unfed virgin adult weevils was dependent upon temperature. Weevils exposed to 70 ±2°F and a constant relative humidity of 72 ± 2% survived 3 times as long as weevils exposed to temperatures of 80±2° and 90±2°F.This publication has 0 references indexed in Scilit:
