Abstract
Juvenile hormone regulates metamorphosis and reproduction in insects.
Compounds with anti-juvenile hormone activity are the new addition to the
integrated pest management strategies to control pests. Among the eight known
types of juvenile hormones in insects, the JH III is the most common one.
Several compounds have been explored for their ability to disrupt the JH titers
in insects and plumbagin, naphthoquinone is one of those. Hence it was thought
worth exploring another naphthoquinone, Juglone for its effect on JH titers in
Dysdercus cingulatus. Insects were collected, reared in the laboratory and
then treated topically using a micro Hamilton syringe. Haemolymph of the
treated and control group was subjected to liquid chromatography quadrupole
time-of-flight mass spectrometry (LC-Q-TOF-MS) to identify and quantify the JH
titers. In the present study, the dose-dependent decrease in the JH titers was
observed before and after mating, which explains the chemosterilent effect of
juglone. Hence, it can be concluded
that anti Juvenile hormone research renders new opportunities for the
development of integrated pest management strategies targeted at the disruption
of juvenile hormone titer.
