Juvenile hormone (JH) is a unique hormone in insects that controls growth, development, metamorphosis and reproduction. It has been well established that JH esterase is an enzyme involved in JH regulation. Results of both in vitro and in vivo studies revealed that ethanol leaf extract of Clerodendrum inerme significantly inhibits haemolymph JH esterase activity affecting growth and normal development of the test insect, castor semilooper (Achaea janata), a serious pest of oil seed crops like castor and groundnut.

Abstract


Juvenile hormone (JH) is a unique hormone in insects that controls growth, development, metamorphosis and reproduction. It has been well established that JH esterase is an enzyme involved in JH regulation. Results of both in vitro and in vivo studies revealed that ethanol leaf extract of Clerodendrum inerme significantly inhibits haemolymph JH esterase activity affecting growth and normal development of the test insect, castor semilooper (Achaea janata), a serious pest of oil seed crops like castor and groundnut.
