Abstract

A continuous laboratory rearing method using rice seedlings was established for the orange leafhopper Cicadulina bipunctata (Melichar), which induces maize wallaby ear disease (MWED) on maize. The generation time was 28 to 35 days and the growth rate (from adults to adults) was 3.9 at a day length of 16 h and a temperature of 25°C. To establish a simple method for evaluating varietal resistance of maize to MWED, two pairs of adult C. bipunctata were released on a six-day-old maize seedling for three days. At six days after removal of the insects the leaf length of the maize seedling was measured and the symptoms of MWED were observed using a rating of 0 to 2 based on the following scale: 0 = no symptom; 1 = slight enlargement of leaf vein; 2 = severe swelling of leaf vein. Using this method, varietal resistance of maize to MWED can be easily evaluated under laboratory conditions.
