摘要
对稀点雪灯蛾Spilosoma urticae(Esper)选用22科47种植物进行室内词养试验,发现该虫可不同程度取食的植物有20科42种。在其取食的植物中具偏嗜选择行为,并具有转移寄主取食为害的习性;幼虫前期如能获得嗜食食料,后期虽得不到嗜食食料,成活率仍较高,但如幼虫前期和后期均得不到嗜食食料,则将降低幼虫的成活率。
The tiger moth Spilosoma urticae (Esper) is a Polyphagous injuriousinsect ingesting plant leaves during the larval stage. When 47 species ofplants in 22 families are given as a diet, 42 species of them are ingested invarying degree and the preference for some of them is proved. The ingesting of different plants during the larval stage can exhibitdifferent effect on Spilosoma urticae's growth and development, survival rate,pupation rate, eeclosion rate, and even can exhibit the destructive effect onthe plants after its eclosion.
