AI Article Synopsis
- - The use of pesticides negatively impacts the environment and encourages pest species to develop resistance, prompting the need for alternative pest control methods.
- - Pheromones, specifically (E)-ß-farnesene (EBF), can disrupt aphid behavior by acting as alarm signals, causing them to stop feeding and leave host plants.
- - Trials conducted in Germany found that dispensers with farnesene isomers reduced aphid populations on sugar beet in some cases, suggesting these could be effective when combined with other pest management strategies, although further research is needed.
Article Abstract
The negative impact of pesticides on the environment and the potential of pest species to develop pesticide resistance make it necessary to explore new methods of pest control. Pheromones and other behavior-modifying semiochemicals are already important in integrated pest management (IPM). (E)-ß-farnesene (EBF) is a semiochemical that acts as an alarm pheromone in aphids. Upon perception of EBF, aphids stop feeding, move away, and sometimes even abandon the host plant. The aphids and are significant crop pests and vectors of many harmful phytopathogens affecting sugar beet (). Field trials were conducted at different locations in Germany to test whether dispensers containing a mixture of farnesene isomers (FIMs) including EBF were able to reduce the infestation of these species on sugar beet. Our results showed a reduction in aphid abundance in the FIM-treated patches in two out of three sites. Therefore, we hypothesize that FIM dispensers could prevent aphid infestation and could be used in combination with other IPM measures. However, more research is required to increase the effect and ensure the reliability of this method.

The northeastern part of China is a traditional sugar beet cultivation area where the soils are classified generally as the black and albic soil types with low boron (B) availability. Boron fertilizer can increase soil B content and significantly improve crop yield and quality. At present, the effects of slow-release B fertilizer on beet root yield and quality remain unclear.

: The rapid development of refrigerated transportation technology for fresh vegetables has extended their shelf life. Some vegetables may appear undamaged on the surface, but their freshness may have decreased, often resulting in the phenomenon of passing off inferior vegetables as good. It is very important to establish a detection method for identifying and assessing the freshness of vegetables.
