In this study, the bioinsecticidal action of a commercial formulation with was evaluated on the new sucking pest in Greece: , of the kiwifruit. Additionally, the biostimulant potential of the same formulation was studied on kiwi growth. The application was performed in three different ways in a commercial field of kiwi crop "Hayward" field in Arta, Greece: (i) trunk spray, (ii) root injection, and (iii) trunk inoculation. During the 2 years seasons of the experiment, weekly measurements of the population were determined. The insect is sucking plants nutrients; therefore, the total chlorophyll content in the leaves of the treatments was recorded weekly. In addition, the percentage of infested kiwifruits was estimated at the end of the experiment. Moreover, to study the biostimulant potential of the formulation, growth measurements on stems and leaves were performed during the experiment. Finally, at the kiwi harvest point, the fruit biomass, dimensions, and weight were obtained, and the leaves' proline content was evaluated. The results encourage us to further study this EPF formulation as the bioinsecticidal effect was noted by the reduction in population, and biostimulant action was perceived by the higher plant biomass.
在本研究中，评估了一种商业制剂对希腊猕猴桃新出现的刺吸式害虫[具体害虫名称未给出]的生物杀虫作用。此外，还研究了该制剂对猕猴桃生长的生物刺激潜力。在希腊阿尔塔的一个商业猕猴桃果园“海沃德”果园中，以三种不同方式进行施用：（i）树干喷雾，（ii）根部注射，以及（iii）树干接种。在为期两年的试验季节中，每周测定[具体害虫名称未给出]种群数量。该害虫吸食植物养分；因此，每周记录处理组叶片中的总叶绿素含量。此外，在试验结束时估算受侵染猕猴桃的百分比。此外，为研究该制剂的生物刺激潜力，在试验期间对茎和叶进行生长测量。最后，在猕猴桃收获时，获取果实生物量、尺寸和重量，并评估叶片的脯氨酸含量。结果促使我们进一步研究这种昆虫病原真菌制剂，因为观察到[具体害虫名称未给出]种群数量减少表明其具有生物杀虫效果，而较高的植物生物量则显示出生物刺激作用。
