| 中文摘要: |
| 桔小实蝇是热带亚热带果树上重要害虫，为明确其在广东湛江常见3种果树上的种群消长规律及其与气象要素的相关性。于2021年1月～2023年12月在湛江的番石榴、芒果、杨桃3种果园设置诱捕器诱捕桔小实蝇成虫，记录种群消长规律，分析其与月平均高温（X1）、月平均低温（X2）、月平均风速（X3）、日均空气指数（X4）和月总降雨量（X5）5个气象要素的相关性，还构建了预测虫量（Y）的线性回归模型。调查发现桔小实蝇在番石榴园的盛发期为5～6月和9月，在芒果园的盛发期为5～8月，在杨桃园的盛发期为5～6月。月平均高温是影响桔小实蝇种群数量的最主要气象因子，方差贡献率达到57.191%，前三个主成分的累积贡献率为94.004%。3个果园虫量预测模型分别为Y1=0.754X1-0.251X2-0.031X3+0.033X4-0.143X5-0.559（番石榴）；Y2=1.532X1-0.623X2-0.099X3+0.101X4-0.112X5-1.301（芒果）；Y3=1.048X1-0.355X2-0.258X3+0.004X4-0.115X5+1.115（杨桃）。桔小实蝇在湛江番石榴、芒果和杨桃树上的种群消长规律不全相同，整体看全年5～9月为桔小实蝇盛发期，月平均高温是最重要的影响因子。 |

| The oriental fruit fly, Bactrocera dorsalis, is a notorious pest on tropical subtropical fruit trees, in order to clarify its occurrence and its correlation with meteorological factors on three common fruit trees in Zhanjiang. From January 2021 to December 2023, traps were set to catch adult B. dorsalis in guava (Psidium guajava), mango (Mangifera indica) and carambola (Averrhoa carambola) orchards in Zhanjiang, Guangdong Province and the population growth pattern was recorded, and its correlation with five meteorological factors, namely, average monthly high temperature (X1), average monthly low temperature (X2), average monthly wind speed (X3), average daily air index (X4) and total monthly rainfall (X5), was analyzed. A linear regression model for predicting insect population (Y) was also constructed. It was found that the blooming period of B. dorsalis in guava orchard was from May to June and September, in mango orchard was from May to August, and in carambola orchard was from May to June. The X1 was the main meteorological factor affecting the population size of the B. dorsalis, with the variance contribution of 57.191%, with the cumulative rate of the first three principal components was 94.004%. The prediction models for the three orchards were Y1=0.754X1-0.251X2-0.031X3+0.033X4-0.143X5-0.559 (guava); Y2=1.532X1-0.623X2-0.099X3+ 0.101X4-0.112X5-1.301 (mango); Y3=1.048X1-0.355X2-0.258X3+0.004X4-0.115X5+1.115 (carambola). The population occurrence of B. dorsalis in guava, mango and carambola orchards in Zhanjiang were not all the same. As a whole, the blooming period of B. dorsalis from May to September throughout the year, and the average monthly high temperature was the primary factor. |
