  • Description: In this work the Author reports his findings on the ethology and ecology of Pandemis heparana Denis and Schiff. (Lep. Tortricidae) on the basis of observations and surveys carried out in 1982-88 in an orchard at Caldaro in Bolzano Province. The Author describes the geographical distribution of the species, and reports shrubs and trees it inhabits. P. heparana overwinters as early larva in the second instar, but, more often, in the third and/or fourth instars in different silky shelters which are constructed by attaching a piece of leaf to twigs, branches and trunks of apple trees. The moth produces two generations yearly. Adult life-span ranges from 5 to 25 days. Females begin egg-laying one day or, more frequently, two or three days after mating. Each one lays from a minimum of two to a maximum of seven egg-clusters (from a minimum of 110 to a maximum of 602 eggs).
