This study was conducted from November 2017 to May 2018 in the experimental field of the Department of Entomology, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh, to investigate the effects of temperature, relative humidity, and rainfall on the incidence of sucking pests (thrips, aphids, and red spider mites) on roses. The results showed that the thrips population started to increase in the first week of January, gradually increasing and reaching its maximum (2.6 ± 0.2 individuals/flower) in the first week of February, and then declining. The aphid population started to increase in the second week of November, reached its peak (8.4 ± 0.6 individuals/shoot) in the last week of December, and then declining. The mite population started increasing in the second week of December, increased continuously until its peak (8.4 ± 0.4 individuals/shoot) in the first week of March, and then declining. The populations of thrips, aphids, and mites persisted until the third week of April, the third week of May, and the first week of April, respectively. Daily mean temperature and rainfall were negatively correlated with the increase in the thrips and aphid populations, while relative humidity was positively correlated with it; however, these correlations were not significant. The mite population had a significant positive correlation with temperature and a non‐significant negative correlation with relative humidity and rainfall. Multiple linear regression analysis showed that weather variables together predicted 34%, 53.1%, and 41.7% of thrips, aphid, and mite abundance on rose plants.

非生物因素与蔷薇植株吸吮害虫发生率的关系

本研究于 2017 年 11 月至 2018 年 5 月在孟加拉加济布尔 Bangabandhu Sheikh Mujibur Ra​​hman 农业大学昆虫学系的实验田进行,旨在调查温度、相对湿度和降雨量对吸吮害虫发生率的影响。蓟马、蚜虫和红蜘蛛螨)在玫瑰上。结果表明,蓟马种群在1月第一周开始增加,2月第一周逐渐增加并达到最大值(2.6±0.2个体/花),然后下降。蚜虫种群在 11 月的第二周开始增加,在 12 月的最后一周达到高峰(8.4±0.6 只/枝),然后下降。螨虫种群在 12 月的第二周开始增加,并持续增加,直至达到峰值(8. 4 ± 0.4 个体/芽)在 3 月的第一周,然后下降。蓟马、蚜虫和螨虫的种群分别持续到 4 月的第三周、5 月的第三周和 4 月的第一周。日平均气温和降雨量与蓟马和蚜虫种群的增加呈负相关,而相对湿度与其呈正相关;然而,这些相关性并不显着。螨种群与温度呈显着正相关,与相对湿度和降雨量呈不显着负相关。多元线性回归分析表明,天气变量共同预测了玫瑰植物中蓟马、蚜虫和螨虫丰度的 34%、53.1% 和 41.7%。蓟马、蚜虫和螨虫的种群分别持续到 4 月的第三周、5 月的第三周和 4 月的第一周。日平均气温和降雨量与蓟马和蚜虫种群的增加呈负相关,而相对湿度与其呈正相关;然而,这些相关性并不显着。螨种群与温度呈显着正相关,与相对湿度和降雨量呈不显着负相关。多元线性回归分析表明,天气变量共同预测了玫瑰植物中蓟马、蚜虫和螨虫丰度的 34%、53.1% 和 41.7%。蓟马、蚜虫和螨虫的种群分别持续到 4 月的第三周、5 月的第三周和 4 月的第一周。日平均气温和降雨量与蓟马和蚜虫种群的增加呈负相关,而相对湿度与其呈正相关;然而,这些相关性并不显着。螨种群与温度呈显着正相关,与相对湿度和降雨量呈不显着负相关。多元线性回归分析表明,天气变量共同预测了玫瑰植物中蓟马、蚜虫和螨虫丰度的 34%、53.1% 和 41.7%。日平均气温和降雨量与蓟马和蚜虫种群的增加呈负相关,而相对湿度与其呈正相关;然而,这些相关性并不显着。螨种群与温度呈显着正相关,与相对湿度和降雨量呈不显着负相关。多元线性回归分析表明,天气变量共同预测了玫瑰植物中蓟马、蚜虫和螨虫丰度的 34%、53.1% 和 41.7%。日平均气温和降雨量与蓟马和蚜虫种群的增加呈负相关,而相对湿度与其呈正相关;然而,这些相关性并不显着。螨种群与温度呈显着正相关,与相对湿度和降雨量呈不显着负相关。多元线性回归分析表明,天气变量共同预测了玫瑰植物中蓟马、蚜虫和螨虫丰度的 34%、53.1% 和 41.7%。螨种群与温度呈显着正相关,与相对湿度和降雨量呈不显着负相关。多元线性回归分析表明,天气变量共同预测了玫瑰植物中蓟马、蚜虫和螨虫丰度的 34%、53.1% 和 41.7%。螨种群与温度呈显着正相关,与相对湿度和降雨量呈不显着负相关。多元线性回归分析表明,天气变量共同预测了玫瑰植物中蓟马、蚜虫和螨虫丰度的 34%、53.1% 和 41.7%。
