    Effect of neem leaf extract and two JH analogues on the development of Callosobruchus Chinensis Linn. (Coleoptera:Bruchidae)
    (Kerala Agricultural University, 1981) Ambika, B; Abraham, C C; Nalinakumari, T
    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.
