Chlorfluazuron (Atabron) is an insect growth regulator (IGR) used for
controlling the major stored product pests. This study investigate the effect of
Chlorfluazuron on both sexes of Tribolium castaneum which resulted from treated 4th
larval instar with LC50 values (1.2ppm for 4th larval instar).
The maximum production and perception of pheromone on both sexes resulted
from treated 4th larval instar were at 8-10 days old while at 4-6 days old in untreated
sexes.
The maximum and minimum pheromone production and perception by sexes
resulted from treated 4th larval instar were at 30oC, while it decline to its lowest titer at
15oC.
The study revealed that both sexes resulting from treated 4th larval instar with
LC50 of Chlorfluazuron caused the formation of abnormal antennae and effect on
number and distribution of the sensillae.
