Toxicity of insecticides, applied as trunk sprays, to the red-necked longhorn beetle Aromia bungii (Faldermann) (Coleoptera: Cerambycidae)

Female fecundity of Aromia bungii (Faldermann) was promoted by coiling peach branches with grafting tape in laboratory experiments because it offered slits for oviposition sites. The toxicity of the insecticides was determined by the number of larvae in the inner bark of the peach branches that were treated with the insecticides. Both acetamiprid and cypermethrin were toxic to the beetles. Acetamiprid had high contact toxicity to adults and cypermethrin suppressed oviposition.
