Role of leaf mines in host location and pupation in Diglyphus isaea (Hymenoptera: Eulophidae)
Diglyphus isaea Walker (Hymenoptera: Eulophidae) is an important ectoparasitic wasp of many leaf miners. Ability of D. isaea to find hosts placed in artificial mines and for its larvae to pupate when the larva is not in a mine was studied. Artificial mines consisted of slits cut in index card sandwi...
