摘要
在10～30℃之间的5种恒温下观测了竹梢凸唇斑蚜Takecallistaiwanus的发育历期,测得其1～4龄若蚜及全若期的发育起点温度分别为12 76℃,9 24℃,7 28℃,6 45℃和8 10℃,有效积温分别为19 66d·℃,19 88d·℃,28 52d·℃,36 49d·℃和115 82d·℃,可供当地预测该蚜虫发生代数和发生期参考。
The development durations of Takecallis taiwanus(Homoptera:Callaphididae)are measured under 5 constant temperatures ranging from 10℃ to 30 ℃.The low-development temperature are 12.76 ℃,9.24 ℃,7.28 ℃,6.45 ℃,8.10 ℃ and the effective thermal constants are 19.66 ℃,19.88 ℃,28.52 ℃,36.49 ℃ and 115.82 ℃ for the development of the 1st,2nd,3rd,4th instar nymphs and whole nymph stage respectively.All these data can be used as reference when the number of generations and time of occurrence need to be forecast at a particular place.[Ch,2 tab.6 ref.]
