Abstract:Research was performed to determine the factors which contribute to increases in aphid and mite populations on pecans following the use of certain insecticides.
Aphid and mite predators had little inhibiting influence, since they were present in equal numbers on both sprayed and unspayed trees.
Tests were performed to determine whether DDT increased the reproductive rate of the black-margined aphid, Monellia costalis (Fitch), and the black pecan aphid, Melanocallis caryaefoliae (Davis). No aphids survived on treated leaves until the residue diminished. After this period, populations were comparable in sprayed and unsprayed leaves, indicating that stimulation by DDT was not a significant factor.
Mechanical factors, such as leaf pubescence and surface residues, appeared to be significant influences on the development of aphid and mite (Tetranychus hicoriae McGregor) infestations following the use of certain insecticides on pecan trees.
