Extensive insecticide use in coffee crops and high death speed are among the main factors of resistance [ 22 ].

The separation of compounds in the column was very clear and the calibration of the equipment coffella severe in order to quantify very small amount of pheromone in the gland, so the quantification was considered accurate.

Chlorantraniliprole showed lower LT 50 of 8.

It is therefore possible to detect resistance to a particular active ingredient by comparing the time of death of each population to different neurotoxic insecticides. Because of the small size, direct observation of the calling behavior is very difficult and inaccurate. Identification, localization and insecticidal synergism with alpha-terthienyl.
