The results showed that the growth, development, reproduction, and life table parameters of Eotetranychus Kankitus were significantly affected by different temperatures. Eggs cannot hatch at 36℃, and other six temperatures had significant influence on the population fitness of Eotetranychus Kankitus. The developmental period was negatively correlated with the temperature. The relationship between temperature (T) and developmental rate (V(G)) for whole generation could be described by the linear model V(G)=-0.037+0.004 T (R2=0.879) and Logistic model V(G)=0.080/(1+EXP(7.402 - 0.363T)) (R2=0.973). The developmental threshold temperature and effectively accumulated temperature for the whole generation were 12.38℃ and 220.00 degree day, respectively. The highest eggs laid per female was 73.4 at 27℃, while the least was 35.3 at 18℃; The greatest hatching rates (99.75%), survival rate of larva (96.18%) and nymph (97.54%) were,all observed at 27℃., whereas the least were 99.01%, 94.05% and 93.15% at 18℃, respectively, The rm under six different temperatures were 0.0372, 0.0757, 0.1024, 0.1195, 0.1469 and 0.1427, while the R0 were 9.3241, 16.0162, 16.6874, 20.4564, 21.1958 and 8.8142, respectively. It was concluded that temperature had a great effect on the development of Eotetranychus kankitus and the optimum temperature range for the mite is from 21℃ to 30℃. 参考文献 相似文献 引证文献
