Abstract Eurygaster
integriceps is a key pest of wheat and barley in
Iran. Neonicotinoid insecticides, a strong group of
insecticides, have good effect on sucking pests. In this
study, effects of four neonicotinods (thiametoxam,
imidacloprid, dinotefuran and acetamiprid) on 3rd nymphs
and adults of E. integriceps via two methods
(contact and chemigation) were investigated. Although
tested insecticides had no strong effect on E.
integriceps in contact method and acceptable mortality
was seen at very high concentration (5 000 mg/L a. i.),
all insecticides had acceptable toxicity to nymphs and
adults through chemigation bioassay. According to
current results, using chemigation can be a novel method
for management of this important pest. |
