Biological activity of permethrin, phenothrin/allerthrin and D-phenothrin on Periplaneta americana and Blattella germanica cockroaches.

The biological activity of permethrin, phenothrin/allethrin and d-phenothrin was evaluated against Periplaneta americana and Blattella germanica cockroaches. A decrease in the number of cockroaches caught after spraying the trial huts was observed. The decrease may be attributed to either the presence of trap-weary specimens or because P. americana is not fully attracted by left over food. One hundred percent knock down was achieved after 10 minutes for all insecticides. The knock down rates for d-phenothrin and permethrin were similar as compared to a combination of phenothrin/allethrin. However, all insecticides were not very effective against cockroaches because the field residual effect was from one day to two days.[1]
