Anthocoris nemoralis is a predatory bug against Psylla pyri. This predatory bug is a real predator against
several types of insects, including aphids and several mites. Eventhough anthocoris closely resembles
Orius spp. it is considerably taller (3 to 4 mm.) with an obviously longer mouth. Anthocoris moves with
Life cycle and relative effectiveness
A female adult lays (for a minimum of) 100 eggs during the course of her life. These eggs are hardly
visible, imbedded in young leaf tops and buds. The eggs hatch within seven days, proceeding their
development to the nymph stage. This stage will take approximately 16 – 18 days, depending on the
climate conditions and nutritional circumstances. Anthocoris nemoralis produces two or three
generations per year. Both, the nymph and adult stage, feed themselves with Psylla pyri. Furthermore,
the eat spider mites, aphids, small caterpillars, moths and several other insects. Anthocoris feeds itself
by using its front legs.
Application and dose
Aim to build a whole population of predatory bugs in an early stage of the season. For example in pear
orchards, Anthocoris will be applied during an early stage of plant development (mainly young plant parts or during flowering period). For every hectare a total amount of 1.400 to 2.000 predatory bugs will be used and applied in the centre of the orchards.
Storage and handling
Anthocoris nemoralis supplied in bottles (500 ml.), containing 200 adults. Keep the bottles horizontally, in darkness, at a temperature between 10°C – 15°C. Maximum storage time of two days.
