Abstract

The whitefly Bemisia tabaci is a destructive insect pest that infects many plants. Finding solutions to reduce the damage associated with whiteflies and their widespread use is of great interest. Therefore, the current research aims to synthesize four polyesters containing a curcumin ring system and investigate their effects against B. tabaci. The synthesized polyesters killed whitefly eggs and their nymphs. Polyester containing a methoxy group (P3) showed the best performance (80.3%) toward the mortality of insect eggs among all the tested polymers. Polyester containing a 4-hydroxybenzaldehyde moiety (P2) showed the lowest mortality efficiency (50.9%) against whitefly eggs after 72 h of treatment. The effect of polyester concentration on the mortality of insect nymphs varied during the treatment period. The mortality rate of nymphs after P3 treatment was the highest (78.0%), whereas that after P2 treatment was the lowest (46.9%). The polyester type, concentration, and treatment duration significantly affected the insect nymph mortality rate. Polyester containing a methoxy group for 72 h resulted in the highest mortality rate (90.0%) against whitefly nymphs.

评估含有姜黄素环系统的聚酯对烟粉虱的影响

烟粉虱是一种毁灭性害虫，会感染许多植物。寻找减少粉虱危害的解决方案以及粉虱的广泛使用引起了人们极大的兴趣。因此，目前的研究旨在合成四种含有姜黄素环系统的聚酯，并研究其对烟粉虱的作用。合成的聚酯可杀死粉虱卵及其若虫。在所有测试的聚合物中，含有甲氧基的聚酯（P3）对虫卵的致死率最高（80.3%）。含有 4-羟基苯甲醛分子的聚酯（P2）在处理 72 小时后对粉虱卵的致死率最低（50.9%）。在处理期间，聚酯浓度对昆虫若虫死亡率的影响各不相同。P3 处理后的若虫死亡率最高（78.0%），而 P2 处理后的若虫死亡率最低（46.9%）。聚酯的类型、浓度和处理时间对若虫死亡率有很大影响。含有甲氧基基团的聚酯在 72 小时内对粉虱若虫的死亡率最高（90.0%）。

期刊介绍： The Journal of Chemical Research is a monthly journal which has a broad international authorship and publishes research papers and reviews in all branches of experimental chemistry. Established in 1977 as a joint venture by the British, French and German chemical societies it maintains the high standards set by the founding societies. Each paper is independently peer reviewed and only carefully evaluated contributions are accepted. Recent papers have described new synthetic methods, new heterocyclic compounds, new natural products, and the inorganic chemistry of metal complexes.
