Abstract:

Biology of big eyed bug, Geocoris erythrocephalus (Lepeletier & Serville) was studied oncabbage aphid, Brevicoryne brassicae (L.) at Centre for biocontrol laboratory, National Institute of Plant Health Management (NIPHM), Hyderabad during 2017.Studies showed the incubation period as 8.20 ± 0.42 days. There were total five nymphal instars and average duration of each successive instar was 4.40 ± 0.52, 8.50 ± 0.53, 6.70 ± 0.48, 7.60 ± 0.52 and 5.20 ± 0.42 days, respectively. The average fecundity was 14.00 ± 3.06eggs with an oviposition period of 3.80 ± 0.63days. The adult longevity of male and female bugs was 7.40 ± 0.52 days and 11.50 ± 0.85days, respectively. The average total life cycle was completed in 40.60 ± 2.89 days.
