ABSTRACT Multiple insecticide treatments were applied to
staked tomatoes in two experiments conducted in 1995 and 1996 to
determine efficacy for control of tomato fruitworm, Helicoverpa
zea (Boddie), green stink bug, Acrosternum hilare (Say),
flower thrips, Frankliniella tritici (Fitch), and potato
aphid, Macrosiphum euphorbiae (Thomas). Flowers were evaluated
for flower thrips populations and tomato leaves were assessed for
potato aphid infestation. At harvest, fruit were examined for tomato
fruitworm and stink bug damage. Varying degrees of control were
observed with the different insecticides: Monitor®, Karate®, and
mixtures of Danitol® with Monitor®, and Karate® with
Monitor® provided satisfactory results against all pests evaluated.
KEY WORDSAcrosternum hilare, Frankliniella tritici,
