Abstract

Phytoseiids are generally predaceousr thus it was not unusual for Jorgensen (1964) and Croft (1968) to find Typhlodromus mcgregori Chant preying on the eggs, larvae, nymphs, and adults of Panonychus ulmi (Koch) (European red mite), Bryobia rubrioculus (Scheuten) (brown mite) 11 and Tetranychus urticae Koch (= telarius (L.) of Jorgensen, 1964). Jorgensen (19649 1967) further reported that To mcgregori occurred in pomaeeous orchards in Oregon and Utah respectively.
