Overwintering larval populations of Amyelois transitella in mummy almo
nds and Anarsia lineatella in hibernaculae on almond trees in Californ
ia orchards were reduced by infectives of Steinernema carpocapsae stra
in All and a cold tolerant Heterorhabditis species (HL81) applied in t
he dormant season. The effect of this reduction in terms of preventing
economic damage the following year is not known. Although the populat
ion reduction mas statistically significant, it is unlikely the increa
se in mortality achieved would prove to be an economically viable alte
rnative to current practices.
