Abstract
Three neonicotinyl insecticides, acetamiprid, thiacloprid and clothianidin, were evaluated for their impact on four species of lepidopteran pests of apple in Washington, the codling moth,
Cydia pomonella
(L.), the Pandemis leafroller,
Pandemis pyrusana
Kearfott, and the obliquebanded leafroller,
Choristoneura rosaceana
(Harris), and
Lacanobia subjuncta
(Grote & Robinson). None of the neonicotinyl insecticides demonstrated sufficient activity against
P. pyrusana
,
C. rosaceana
, or
L. subjuncta
to warrant field trials. Conversely, all had some activity against one or more stages of
C. pomonella
. Acetamiprid was highly toxic to larvae in laboratory bioassays, and had relatively long activity of field-aged residues (21 days). It also showed some toxicity to
C. pomonella
eggs (via topical exposure) and adults. Acetamiprid provided the highest level of fruit protection from
C. pomonella
attack in field trials conducted over five years in experimental orchards with extremely high codling moth pressure. Thiacloprid performed similarly in bioassays, but fruit protection in field trials was slightly lower than acetamiprid. Clothianidin showed moderate to high toxicity in bioassays, depending on the
C. pomonella
stage tested, but poor fruit protection from attack in field trials. None of the neonicotinyl insecticides were as toxic to larvae or effective in protecting fruit as the current standard organophosphate insecticide used for
C. pomonella
control, azinphosmethyl. However, both acetamiprid and thiacloprid should provide acceptable levels of
C. pomonella
control in commercial orchards where densities are much lower than in the experimental orchards used for our trials. The advantages and disadvantages of the neonicotinyl insecticides as replacements for the organophosphate insecticides and their role in a pest management system for Washington apple orchards are discussed.
