摘要:
Pecan weevils,Curculio caryae(Horn)2, were found deeper in cultivated soils than in undisturbed sites, within the foliage canopy of the tree. No pecan weevils were found in unshaded soil outside of the tree canopy. Male and female weevils were homogenous in their vertical distribution within the soil. The depths at which weevils were found were apparently deeper than necessary to escape inclement weather at the sites studied.
