Influence of host plants on the development and survival of Lymantria obfuscata.
In laboratory studies in India, larvae of Lymantria obfuscata were reared on the leaves of 15 species of fruit and forest trees to determine the influence of food-plant on development and survival. Development was faster and survival higher on Salix alba, Populus nigra and the apple varieties Red Delicious and American Apirouge. Development was slower and survival lower on almond, cherry, apricot, walnut and P. alba. Larvae failed to survive on the pear varieties William and Sand. Newly-hatched larvae failed to survive on apricot and cherry, but larvae initially reared on S. alba for 3 days had a prolonged larval period and low survival on apricot and cherry.
