The cis-isomer was more active than the trans-isomer in the three stages evaluated. When the two isomers were simultaneously applied to first instar nymphs, an additive effect was observed. Similar treatments of third and fifth instar nymphs resulted in an antagonistic effect. In third instar nymphs, the cis-isomer was more active than trans-isomer at all the three temperatures assayed (16°, 26°, and 36°C). The toxicity of the cis-isomer was lower at 36°C than at either 16° or 26°C. Temperature had no significant effect on the toxicity of the trans-isomer within the temperature range assayed. The toxicity of either isomer to third instar nymphs was not affected by pretreatment of nymphs with PBO (an inhibitor of mixed-function oxidases activity) or TPP (an inhibitor of esterase activity), suggesting that these detoxification pathways are not relevant in the metabolism of cis- or trans-isomers.
