ABSTRACT
Biology of Snellenius maculipennis (Szepligate), a solitary endolarval parasitoid of castor semilooper Achaea janata (Linnaeus) were studied under the laboratory conditions at 28 ± 2˚C temperature and 75-80 per cent RH during kharif, 2017. Biology of S. maculipennis were studied on six varieties of castor with different blooms i.e., DPC-9 (Green zero), DCH-177 (Red single), PCH-111 (Green double), 48-1 (Red double), DCH-519 (Green triple), GCH-4 (Red triple). In our investigation, biological parameters of S. maculipennis such as egg+ larval, cocoon and adult duration ranged from 5.25 to 5.75, 4.50 to 4.75, 3.50 to 3.75, respectively, when reared on castor varieties with different blooms. The total life cycle duration of S. maculipennis was higher when reared on variety, GCH-4 (13.7±0.95 days) and lowest durations of total life cycle were observed when reared on DPC-9 (13.2±0.50 days).
Keywords: Biology, Castor semilooper, Achaea janata, Endolarval parasitoid, Snellenius maculipennis.
