Predation by thrips was referred to as early as 1882 when Pergande discussed their habits. Later, Plank (1936) found Leptothrips mali (Fitch) to be predaceous on lepidopterous eggs, and Sharp (1938) cited it as a being a predator of the pecan nut caseborer, Acrobasis caryae Grote. Bailey (1939) stated that the six-spotted thrip, Scolothrips sexmaculatus (Pergande), is predaceous on Tetranychus telarius (L.), Tetranychus pacificus McG., Bryobia praetiosa Koch, Paratetranychus citri McG., Paratetranychus pilosus (C & F.), Paratetranychus indicus Hirst, Paratetranychus yothersi (McG.), Paratetranychus ilicis (McG.), and Phyllocoptes oleivorus Aschm. and in 1943 Bailey and Keifer noted that L. mali fed on tomato russet mite, Phyllocoptes desctructor (Keifer). Muma (1955) discussed the predation of S. sexmaculatus, L. mali, and Aleurodothrips fasciapennis (Franklin) on citrus insects and mites in Florida.
