为确定三种蜘蛛螨的发育和繁殖的最佳温度范围(Eotetranychussexmaculatus,东方eotetranychus,和Oligonychusbiharensis),这项研究调查了它们的发育时期,存活率,寿命,在五个温度下繁殖,21、24、27、30和33°C,在现场进行预测和控制。有了收集的数据,为他们每个人构建了一份两性生活表。结果表明,随着温度的升高,O.Biharensis和E.Orientalis的世代均逐渐减少。此外,在所有三种蜘蛛螨物种的寿命和温度之间都观察到了反比关系。当检查不同温度下的存活率时,E.sexmaculatus在33°C时表现出最高的比率(98%),而东方大肠杆菌和O.Biharensis在24°C时表现出最高的存活率,分别达到90%和100%。关于繁殖,O.Biharensis在30°C时产卵率最高,平均每个人17.45个卵。相反,在33°C时,雌斑大肠杆菌和东方大肠杆菌的产卵率最高,平均每个个体分别为15.22和21.38个卵。在33°C下,观察到O.biharensis和东方大肠杆菌的固有生长速率显着提高,率分别为0.22和0.26。相比之下,E.sexmaculatus在27°C时表现出最高的内在生长速率。27°C的温度更适合六斑大肠杆菌的生长,而33°C是东方大肠杆菌和O.Biharensis的最佳温度。目前的研究结果为这三种蜘蛛螨的控制和预防提供了有价值的指导。
To determine the optimal temperature range for the development and reproduction of three spider mites (Eotetranychus sexmaculatus, Eotetranychus orientalis, and Oligonychus biharensis), this study investigated their developmental period, survival rate, lifespan, and reproduction under five temperatures, 21, 24, 27, 30, and 33°C, to predict and control in the field. With the gathered data, a two-sex life table was constructed for each of them. The results revealed that as the temperature increased, both O. biharensis and E. orientalis displayed a gradual reduction in their generation period. Furthermore, an inverse relationship was observed between lifespan and temperature for all three spider mite species. When examining the survival rates at varying temperatures, E. sexmaculatus exhibited the highest rate (98%) at 33°C, while E. orientalis and O. biharensis demonstrated their highest survival rates at 24°C, reaching 90% and 100% respectively. Regarding reproduction, O. biharensis displayed the highest oviposition rates at 30°C with an average of 17.45 eggs per individual. Conversely, E. sexmaculatus and E. orientalis exhibited the highest oviposition rates at 33°C, averaging at 15.22 and 21.38 eggs per individual respectively. Significantly higher intrinsic growth rates were observed for O. biharensis and E. orientalis at 33°C, with rates of 0.22 and 0.26 respectively. In contrast, E. sexmaculatus demonstrated the highest intrinsic growth rate at 27°C. The temperature of 27°C was more suitable for the growth of the E. sexmaculatus, while 33°C was the optimal temperature for the E. orientalis and O. biharensis. The current findings provide valuable guidance for the control and prevention of these three spider mites.
