Song Ming is located in Forest Park, Prince Rock Mountain, the relative elevation, and many types of animals and plants, shrubs up to more than 130 kinds, Division of alpine fir, iron Cheng; Center distributed spruce, red Betula, birch, mountain Yang; low distribution of Chinese Pine Mountain, poplar, larch; forest, bright colors, unique shape of the azalea flower, Hydrangea macrophylla, primrose, willow spent nearly a hundred species of wild flowers, etc.; have distributed widely; a large number of Zushima, 3-pin, 9 calamus, Sichuan Chishao, Astragalus, purple Hu, deer, such as with grass.

松鸣岩森林公园地处太子山林区，相对高差大，动植物类繁多，乔灌木多达130多种，高山分部着冷杉、铁桦；中心分布着云杉、红桦、白桦、山杨；低山分布油松、杨树、落叶松；林中花色鲜艳，花形独特的杜鹃、八仙花、报春花、柳叶花等近百种野生花卉；有分布广范；数量较多的祖师麻、三棵针、九节昌蒲、川赤芍、黄芪、紫胡、鹿含草等。

The ecdysis index of controlled larvae was 3.323 by 30d, while 2.933-3.038 for the treated. The transgenic Betula platyphylla could reduce the feeding of larvae. With the increase of the time of feeding, the difference of food taken between the controlled and treated became larger. The food of controlled larvae taken was 0.105293-0.13750 grams than that of the treated by 3 d. and 0.529094-0.64103 grams by 21d.

转基因植株能够降低幼虫的食叶量，3天时对照幼虫的食叶量比处理幼虫的食叶量多0.105293～0.137504克；21天时对照幼虫食叶量比处理幼虫食叶量多0.529094～0.64103克，随取食时间的延长，对照幼虫的食叶量与处理幼虫的食叶量差别更大，转基因植株的抑制作用更明显。
