Title:On the Parasites of the Lesser Apple Leaf-Roller, Teras Minuta (Robs)
Author(s):Weed, C.M.
apple leaf-roller
State Entomologist of Illinois
Abstract:In a paper to be published in the Report of the State Entomologist of Illinois for 1886, I have discussed ab length the literature and life-history of the Lesser Apple Leaf-Roller, originally described by Robinson as Tortrix minuta, and since re-described by Le Baron, Riley, Packard, and Zeller under the specific names of malivora^ia, Cinderella, vacciniivorana and variolana. I have there shown that** the life-history of the species when feeding upon apple is the same as when feeding upon cranberry. Dr. Riley having proved that in the latter case the species is dimorphic, — there being a yellow summer form and a gray winter form. The parasites described below were mostly bred at the Laboratory during 1886, though a few had been obtained during previous seasons. It is a little remarkable that although this leaf-roller has been so often injurious both upon apple and cranberry, and has frequently been treated of in entomological literature, there has heretofore been recorded but one species of parasite bred from it, (obtained from cranberry-feeding larvae). Yet from the frequently recorded fluctuations in the numbers of the large upon apple, it seems probable that they have been subject to parasitic attack for many years.
