摘要:

【目的】 研究棉田花蓟马种群消长动态及空间分布型。【方法】 采用五点取样法进行田间取样;利用广义线性混合模型分析棉株叶片、花和棉铃上花蓟马种群动态;应用5种聚集度指标和Taylor幂法则分析棉田花蓟马的空间分布型。【结果】 棉田花蓟马种群数量从6月中旬至7月上中旬逐渐上升,7月中下旬至8月中旬达到高峰,8月下旬后至9月初逐渐下降直至消失。花蓟马种群数量在棉花的叶片、花和棉铃上存在显著性差异,种群随着调查时间的变化而波动,且种群随时间变化而波动在不同器官之间也存在显著性差异。在花蓟马种群的初始增长期、爆发高峰期、下降期及全时期中,花上具有最高的花蓟马种群数量。花蓟马在棉田的空间分布型为聚集分布,且聚集度具有密度依赖性。【结论】 7月中下旬至8月中旬是棉田花蓟马种群爆发期,其种群在棉田成聚集分布,且主要聚集于棉株花中。

Abstract:

【Objective】 To clarify the population dynamics and spatial distribution pattern of Frankliniella intonsa in cotton fields. 【Methods】 The five-point sampling method was used for field sampling and generalized linear mixed models were used to analyze the population dynamics of F. intonsa on leaves, flowers, and bolls of cotton; And five aggregation indexes and Taylor Power Law were applied to analyze the spatial distribution pattern of F. intonsa in cotton fields. 【Results】 F. intonsa populations in cotton fields gradually increased from mid-June to mid-July, peaked from late July to mid-August, and then gradually declined until they disappeared from late August to early September. Population levels of F. intonsa differed significantly among different organs and fluctuated with sampling date. The temporal variation of F. intonsa populations were significantly different among different organs. Flowers had the highest population level of F. intonsa during the initial growth period, peak outbreak period, decline period, and full period. The spatial distribution of F. intonsa in cotton fields was aggregated distribution and the aggregation was density-dependent. 【Conclusion】 Late July to mid-August is the outbreak of F. intonsa populations in cotton fields, and its distribution type in cotton fields is aggregated distribution, and the populations are mainly aggregated in flowers.
