The most common predator mite found in
mint is Neoseiulus fallacis (=Ambyleius fallacis). This predator is
about 0.25 to 0.5 mm long, yellow to almost translucent and "pear-shaped". These
mites overwinter as adult females in the soil or crop debris. Adults become active in the
spring and lay eggs on leaves. Eggs hatch in 2 to 3 days and larva feed for 1 to 2 days
before molting to the protonymph stage. This stage consumes about 2 prey and completes
development to the deutonymph stage in 1 to 2 days. The deutonymph stages lasts 1 to 2
days before molting to the adult. Adult females consume nearly 2 prey/day during a 5 to 6
week period. Females consume about 75 to 80 total prey and lay about 33 eggs during her
lifetime. The life cycle from egg to adult requires about 6 days and there are at least 10
generations each year. |
