Dipha aphidivora (Meyrick), a lepidopteran predator of sugarcane woolly aphid (SWA) Ceratovacuna lanigera Zehntner was successfully reared for three successive generations, for the first time on a freeze-dried beef liver-based larval semi-synthetic diet. We compared biological parameters viz., larval survival, adult weight, pre-and oviposition period, fertility, fecundity and female longevity of D. aphidivora reared on the semi-synthetic diet with the predators reared on SWA. Development time of larvae reared from first instar to pupation was 20.6 days on the semi-synthetic diet and 12 days on SWA, while survival of the larvae to adults was 61.8 and 91.8% on larval semi-synthetic diet and SWA, respectively. Fecundity recorded from semi-synthetic diet (41 eggs/female) was significantly less than those produced on SWA (58 eggs/female). However, fertility and longevity of the predators reared on SWA and semi-synthetic diet did not differ significantly. The study revealed the possibility of rearing D. aphidivora larvae using synthetic diet. |
