济南市郊笨蝗生态习性的研究

STUDIES ON THE ECOLOGICAL HABITS OF HAPLOTROPIS BRAUNNERIANA SAUSSURE IN THE SUBURBS OF JINAN

在山东省济南市郊,笨蝗分布于南部丘陵山区,适栖于干旱向阳的荒坡及林缘草灌丛,有时侵入旱地农田,危害作物.笨蝗属于植食性蝗类,但取食有一定选择性.从该种的生态分布、栖境选择、偏喜的食料植物以及适宜的温度、湿度和光照等综合表明,笨蝗为典型干旱生境特征种.

In the suburbs of Jinan, the Haplotropis braunneriana are distributed only in the sourthern hilly areas. This species likes to live in the grasses with shrubs along wild slopes and margins of woods facing the sun 5 sometimes they invade the arid farmland damaging the crops. These grasshoppers belong to phytophaga, but they select certain plants for their food. According to their ecological distribution,selection of habitats,their preference for food plants,suitable environmental temperature, humidity,light conditions and so on,they belong to typical species of arid biotopes in these areas.
