P. Pats et Mb. Isman, EFFECT OF NEEM ON ADULT LONGEVITY, OVIPOSITION AND LARVAL DEVELOPMENTOF THE CABBAGE FLY, DELIA-RADICUM (L.) (DIPT., ANTHOMYIDAE), Journal of applied entomology, 122(2-3), 1998, pp. 125-127
Neem seed extract was evaluated at a concentration of 50 p.p.m. azadir
achtin for potential oviposition deterrence, and for effects on larval
survival, adult longevity and fecundity in the cabbage fly (Delia rad
icum). Oviposition was not deterred, nor was larval survival or fecund
ity affected. Adult longevity was not significantly reduced when neem
seed extract was added to the diet.
