This large variation represented by RT 50 indicates that populations show differences in susceptibility and greater or lesser sensitivity to the enzyme acetylcholinesterase since variations were observed between leucopgera that died the fastest and those that died more slowly.

Pharmaceutical Biologyv. Preliminary tests using only discs soaked in water were carried out to observe caterpillar mortality over a h period.

Insecticides provide the most efficient method of controlling this pest, with more than 30 different active pesticides registered for use against this L. Receive exclusive offers and updates from Oxford Academic.

Extensive insecticide use in coffee crops and high death speed are among the main factors of resistance [ 22 ]. In brief, the coffee green leaves, where the larvae develops and pupate, were maintained in the solution of benzyladenin 10 -7 mol L Analogously, the freeze-dried extracts from Mangifera indicaMusa sapientumOcimum basiculum and Psidium guajava also increased L.

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.
