Title: Animal Pests of Cultivated Mushrooms in the United States
Author: C.A. Thomas


This paper gives short accounts of the biology and mode of action of the important animal pests affecting cultivated mushrooms in the United States and the present status of their control.

Cultivated mushrooms in the United States are subject to injury by species of at least three families of Diptera (Mycetophilidae, Cecidomyiidae and Phoridae); by several species of Collembola or springtails; by mites of the genera Linopodes, Tyroglyphus, Rhizoglyphus, Histiostoma and Pygmaeophorus; and by several kinds of nematodes or eelworms (Ditylenchus, Rhabditis, etc.). Many other species of insects and mites are found in compost piles and in the mushroom houses, but fortunately, they are either harmless insofar as the crop is concerned, or some of them actually feed on the other animal pests.

Nematodes, mites, springtails and fly stages may enter mushroom houses in a number of ways : by crawling into the compost pile from the soil beneath it and then being carried into the house in the compost when the beds are filled; by being carried into the beds in the casing soil; or by flying or crawling through the ventilators and doors. Prevention and sanitation, as described later, are therefore important in keeping these pests from entering the house. Once within the beds, each kind of pest causes its own type of injury and must be handled in a specific manner.
