Abstract:
In studies on the comparative effectiveness of neem extract and the
juvenile hormone analogues Hydroprene (ZR-512) and MV-678 against
Callosobrucbus chinensis, it was found that in greengram seeds treated with
0.25 wg of Hydroprene, there was significant reduction in fecundity and progeny
production of the insect. The neem leaf extracts at 2.5 and 5.0% and MV-678
at 0.5 ug were as effective as Hydroprene in suppressing progeny production.
The feasibility of utilising JH analogues and neem leaf extracts for the management
of C, chinensis has been discussed.
