The effect of six constant temeperatures (10°C, 15°C, 20°C, 25°C, 30°C and 35°C) and two relative humidities (70% and 90%) on the biological parameters of brown planthopper (BPH) viz., the duration of egg and nymphal instars, adult longevity, fecundity, % survival of nymphs, as well as proportion of macropterous and brachypterous and females was studied with the aid of environmental chamber. The egg period was reduced from 14.18 days at 15°C to 6.32 days at 30°C; nymphal period was lowered from… CONTINUE READING
