According to recent research published in the Journal of Economic Entomology, "Pyrethroid resistance in Helicoverpa armigera (Hubner) field populations was investigated in Benin over several years by using third- and fourth-instar larval topical bioassays. H. armigera. was resistant to pyrethroids tested as cypermethrin, deltamethrin, bifenthrin, and fenvalerate. Pretreatment with piperonyl butoxide significantly decreased the LD50 value of cypermethrin and deltamethrin, and the resistance suppression by this synergist effect was observed."
"No significant decrease in the LD50 value was obtained when S,S,S-tributyl phosphoro-trithioate was applied before ...
