Introduction

Environmental conditions

Relative humidity should be greater than 75% and the temperature above 20°C/68°F for some hours of the day. Phytoseiulus persimilis does not enter diapause.

Storage and handling

Appearance

Adults: bright red, very active, spherical, stands high on its legs

Eggs: oblong, first pink and transparant, later on darker, twice as big as spider mite eggs

Larvae/nymphs: pale to light red

Mode of action

Adult predatory mites and nymphs search actively for their prey and suck them dry.

Visual effect

Adult red spider mites that have been eaten change colour from brown to black (in tomato) and can be identified as tiny black dots on the leaves. This should not be confused with living, light-brown to dark-red spider mites.
