Creator:

Groth, Eric M.

Abstract:

Pergamasus quisquiliarum Canestini is a polyphagous predatory mite that has been shown to feed on the economically important arthropod, Scutigerella immaculata Newport (Symphyla: Scutigerellidae), Collembola, Diptera larvae, Enchytraeid worms, and miscellaneous other soil organisms. This study examined the feeding behavior of P. quisquiliarum, the effects of cover cropping and tillage...

Biological control of Tetranychus urticae (Koch) on peppermint by Neoseiulus fallacis (Garman) : density relationships, overwintering, habitat manipulation and pesticide effects

Creator:

Morris, Mark Alan, 1954-

Abstract:

Several aspects affecting population trends and overwintering of Neoseiulus fallacis (Garman) on peppermint were examined. Neoseiulus fallacis was the most abundant phytoseiid predator mite found in peppermint surveys throughout the western U.S. Results of pesticide exclusion and cage studies showed that N. fallacis controlled Tetranychus urticae (Koch) on peppermint in...
