Abstract
Surveys in unsprayed orchards showed that the wild flowers that are food sources for adult parasites influence the extent to which host Lepidoptera are parasitized. Proportionately about 18 times as many tent caterpillar pupae were parasitized in orchards with rich undergrowths of wild flowers as in orchards with poor floral undergrowths. The corresponding figures for tent caterpillar egg parasitisms were about 4 to 1, and for codling moth larvae about 5 to 1. Orchards with average undergrowths of wild flowers produced intermediate figures.This publication has 8 references indexed in Scilit:
