Pest Remedies-Bugs:
Bug, Apple Red (Lygidea mendax)
Order: Hemiptera; Family: Pyrrhocoridae
Description: Adult, active, bright red, 6 mm(1/4"), fly readily from tree
to tree.
Life Cycle:
Overwintering is in the egg stage, in lenticels on the bark of smaller branches and the
nymphs appear in the early pink stage of apple bloom, puncturing leaves as they unfold and
feeding on the fruit as it reaches about 6 mm (1/4") in diameter. Adulthood is
reached in June.
Hosts/Damage:
Nearly all varieties of apples and may attack pear, hawthorn and wild crab apples.
Leaves are curled and there are numerous small sunken spots where the beak punctures the
fruit; the fruit is deformed, pitted in a dimpled effect, sometimes russeted; the texture
is woody.
