| 内容記述 | The authors have studied the distribution of the Epilachnid beetles in Gumma-pref. since 1956, and the following results are obtained as summary. 1. Epilachna sparsa is recognized to be distributed to some extent at the southern plain places of Gumma-pref. such as Tomioka, Takasaki, Maebashi, Ogomachi, Isezaki, Ota, Tatebayashi, Kasakakemura and their neighbors, where the altitude is less than 150m (Fig. 1). At these places sparsa lives intermingled with 28-maculata. 2. At the higher places with 150～300m altitude such as Shibukawa, Onogami, Yoshioka, Misato, Akagimura, Hokkitsumura, Komochimura and their neighbors (Fig. 1), sparsa tends to live being segregated from 28-maculata in the same farm. 3. The species feeds usually on the Solanaceous plants, among which ground cherry is the best host plant. The number of the generation is generally two but rarely three. 4. E. 28-maculata is the species having the widest distribution in Gumma-pref. (Fig. 1) and we can see it everywhere, potatoes, egg-plants and tomatoes are planted, with exception of one place near Ozegahara. The highest limit of the distribution may be 1300m. 5. The host plant of 28-maculata is the Solanaceous plants with the exception of ground cherry and redpepper, on which the larvae cannot grow. The number of the generation is one but very rarely may be two. 6. Ea pustulosa inhabits mainly at the northern places of Gumma-pref. such as Anabara, Hikagenango, Neri, Akagizawabashi, Tokusa, Kashozan, Akakura, Doai, Fujiwara, Uenohara, Sugenuma, H6shi and Omineyama. All these places are located along the Tone River system with more than 600m altitude and have heavy snowfall (Fig. 1). However, pustulosa is also found at Sebayashi of Tano-gun in the southwest Gumma. 7. The true host plant of pustulosa is the thistle (Cirsium nipponicum (MAXIM.) MAKINO var. incomptum (FR. et SAV.) KITAM. belonging to Compositae in Gumma-pref., but the beetle eats sometimes the Solanaceous plants espe-cially potato-plant. With an exceptional case the authors observed that the adults were attacking burdock leaves. 8. The distribution of sparsa is expanding northwardly year after year in Kanto District and the northern limit of the distribution runs along the line denoted in Fig. 3 and 4 at present. 9. This phenomenon is not only noticeable for ecological problem, but also very important for agriculture because the beetle probably gives a fear of attacking the Solanaceous vegetables as a new pest in the new habitats. | |||||||||||
