摘要

本试验旨在研究2019年和2020年阿西尤特省玉米主要害虫的季节丰度及其与天敌和气象因子的关系。6月至9月对样本进行了调查,确定了禾蓟马(Haliday, 1836)、野蓟马(Fitch, 1856)和芝麻马(Sesamia cretica Lederer, 1857)及其相关捕食者的种群数量。谷草乳杆菌种群在2019年7月4周和2020年8月1周达到高峰。两个季节中均以9月第1周为最高。小麦黑麦草种群与3个气象因子之间的简单相关和回归均不显著,而小麦黑麦草种群与R.H%之间的简单相关和回归均显著。第1季与气温呈不显著负相关,第2季呈显著负相关。植物年龄对三种害虫种群的影响大于天气因素。常见的捕食者为白翅螟(Orius albidipennis, Reuter, 1884)和断翅螟(Scymnus interruptus, Goeze, 1777)。

Seasonal abundance of the most important insect pests of maize and their natural enemies in Egypt
The experiment was conducted to study the seasonal abundance of the most important insect pests of maize and its relation with natural enemies and weather factors in Assiut governorate during 2019 and 2020 seasons.The samples were examined from June to September to determine the population of Limothrips cerealium (Haliday, 1836), Rhopalosiphum maidis (Fitch, 1856) and Sesamia cretica Lederer, 1857 and its the associated predators. The population of L. cerealium recorded a peak in the 4 week of July 2019 and the 1 week of August 2020. The highest population of R. maidis occurred in 1 week of September at both seasons. The simple correlation and regression between L. cerealium population and three weather factors were insignificant in both seasons while S. cretica population were found to be significant with R.H%. The population of R. maidis in the 1st season was insignificant negative with temperatures but was significant in the 2nd season. The plant age was more effective than the weather factors on the population of the three insect pests. The common predators were Orius albidipennis (Reuter, 1884) and Scymnus interruptus (Goeze, 1777)which were highly significant with all three insect pests.

期刊介绍: The Polish Journal of Entomology was founded in 1922 as a periodical of the Polish Entomological Society under the title Polskie Pismo Entomologiczne (subtitle Bulletin Entomologique de Pologne). The journal publishes original research papers and reviews from any entomological discipline. The Polish Journal of Entomology is sponsored by the Polish Entomological Society and the Ministry of Science and Higher Education. It deals with all aspects of entomology and has no geographical limits. Four issues of the journal are published annually. It is covered by the Zoological Record, Entomological Abstracts, Biological Abstracts. Each article has its own DOI
