“…Cicadulina bipunctata occurs in the southern parts and middle-western parts of Kyushu (Webb 1987;Matsukura et al 2009a), and our most recent study revealed that the leafhopper is also distributed in the middle-eastern parts, but not in the northern parts, of Kyushu (Kumashiro et al 2012). Until now, C. bipunctata had not been reported from Shikoku or the Kii Peninsula, Honshu, even though the annual mean temperatures of these areas are rather higher than in the middle parts of Kyushu (Japan Meteorological Agency 2011).…”

“…In Japan, this species is known to occur in the Bonin Islands (Matsumura 1914), the Ryukyu Islands (Hayashi 2002), and Kyushu (Matsumura et al 2006;Matsukura et al 2009a;Kumashiro et al 2012). The leafhopper feeds on various Poaceae including important crops, such as maize, rice and wheat (Maramorosch et al 1961;Catindig et al 1996;Kumashiro et al 2011).…”

“…In Kyushu Island, Japan, C. bipunctata had been recorded in only one of seven prefectures (Kumamoto prefecture) for more than 70 years since the first record in the 1910s (Matsumura 1914), but it is now present in all seven prefectures following gradual range expansion that probably started in the late 1980s . MWES has been a serious problem in the central and southern plains areas of the island since the early 2000s (Kumashiro et al 2012;Matsukura and Matsumura 2013). The leafhopper was also found in Shikoku Island, east of Kyushu, in 2011 .…”

Future risk of the maize orange leafhopper, Cicadulina bipunctata, and maize wallaby ear symptom in temperate Japan

Since the 1980s, the maize orange leafhopper, Cicadulina bipunctata, has been gradually expanding its range in east Asia associated with global warming. This leafhopper induces maize wallaby ear symptom (MWES) on young maize plants and has become a threat to forage maize production in southern parts of temperate Japan since around 2000. In this study, using predictions of future temperature and precipitation calculated from Atmosphere-Ocean Coupled General Circulation Models, the future risk of C. bipunctata expansion and MWES occurrence in Japan (spatial resolution: 1 km 2 ) was predicted. A nominal logistic regression analysis showed a significant contribution of cumulative low temperature during winter to the current distribution of C. bipunctata. The range of C. bipunctata was predicted to expand northward, particularly in Kyushu, Shikoku and the southern part of Honshu after the 2060s. Predicted intensification of MWES would reduce the efficacy of maize cultivars that are currently tolerant to MWES, in southern Kyushu in the 2020s, and in most parts of Kyushu, Shikoku and southwestern Honshu in the 2060s. These results suggest the need for measures to counter further expansion of C. bipunctata and improvement of current tolerant maize cultivars.

Recent global warming has caused the maize orange leafhopper, Cicadulina bipunctata (Melichar), to proliferate in Kyushu, Japan. This leafhopper feeds on several species of poaceous plants. Some host plants such as maize, rice, wheat and oats show abnormal growth, characterized by stunted growth and swelling (upheaving) of leaf veins when attacked by C. bipunctata. This abnormal growth is not caused by a virus or phytoplasma, but by the injection of chemical(s) from the leaf hopper into the plants. In central and southern areas of Kyushu, serious damage arising from this abnormal growth is known as maize wallaby ear symptom (MWES) and occurs on forage maize during the second cropping season (from late June to November). The degree of MWES is highly dependent on the level of infestation (period and density) by C. bipunctata, and since C. bipunctata density is quite low until mid-July, the earlier seeding of the second crop and the use of MWES-resistant varieties is an effective way to avoid damage from MWES. This leafhopper shows a unique relationship between plant and herbivores because MWES induction by adult C. bipunctata helps improve the development of their offspring through the accumulation of amino acids on the host plant.
