Abstract

ABSTRACT: The European wheat stem sawfly, Cephus pygmeus (Linnaeus, 1767) and the black grain stem sawfly, Trachelus tabidus (Fabricius, 1775) are important and common pests in wheat growing areas of Turkey. These sawfly species continue to be a threat to wheat production in the southeast Anatolia Region of the country. This study was conducted to determine larval infestation rates and yield losses caused by these sawfly species in common wheat cultivars grown in the southeast Anatolia Region. Durum and bread wheat fields were surveyed to record larval infestation and damage caused by these sawfly species in four provinces (Adıyaman, Diyarbakır, Mardin and Şanlıurfa) of the region. A total 100 wheat fields were randomly selected and stem samples were taken from each field during the harvest period. Spike length, mean number of grains, grain weight and 1000-grain weight were recorded from 100 infested and healthy spikes and crop losses were calculated for 16 wheat cultivars. The surveyed provinces significantly differed in infestation rates, with the highest infestation level recorded for Diyarbakır province with a mean of 17.4% (range 2.1- 54.3%), while the minimum infestation was determined in Adıyaman province with a mean of 5.3% (range 1.4-17.3%). Durum and bread wheat cultivars had negligible effects on larval infestation. Spike length of infested wheat plants was reduced by 0.9-14.4% and the mean number of grains and grain weight were reduced by 0.5-19.7% and 7.2-28.5%, respectively. The loss in 1000-grain weight was 8.9% in bread wheat cultivars, while the loss was 7.9% in durum wheat cultivars. It was concluded that the loss in 1000-grain weight reached 10.9%. Therefore, appropriate control measures should be taken against stem sawflies in high-infestation locations.

小麦茎锯蝇(膜翅目:锯蝇科)对土耳其安纳托利亚东南部部分小麦品种的感染与危害
摘要:欧洲小麦茎锯蝇Cephus pygmeus(Linnaeus,1767)和黑粒茎锯蝇Trachelus tabidus(Fabricius,1775)是土耳其小麦产区常见的重要害虫。这些锯蝇物种继续威胁着该国东南部安纳托利亚地区的小麦生产。本研究旨在确定这些锯蝇物种在安纳托利亚东南部地区常见小麦品种中的幼虫侵扰率和产量损失。对该地区四个省(Adıyaman、Diyarbakır、Mardin和Şanlıurfa)的杜伦麦田和面包麦田进行了调查,以记录这些锯蝇物种造成的幼虫侵扰和损害。总共随机选择了100块麦田,并在收获期从每块麦田中采集了茎干样本。记录了100个受感染和健康穗的穗长、平均粒数、粒重和1000粒重,并计算了16个小麦品种的作物损失。受调查省份的虫害率差异显著,迪亚巴克尔省的虫害水平最高,平均为17.4%(范围为2.1-54.3%),而阿达曼省的虫害率最低,平均为5.3%(范围1.4-17.3%)。杜伦和面包小麦品种对幼虫虫害的影响可忽略不计。受害小麦植株的穗长减少了0.9-14.4%,平均粒数和粒重分别减少了0.5-19.7%和7.2-28.5%。面包小麦品种的1000粒重损失为8.9%,硬粒小麦品种的损失为7.9%。结果表明,1000粒重损失达10.9%,因此,应采取适当的防治措施,防治高虫害地区的茎锯蝇。
