The indiscriminate use of synthetic insecticides has led to the emergence of resistant populations of Plutella xylostella L. (Lepidoptera: Plutellidae), hindering its control and causing economic damage to brassica production. Thus, in order to seek control alternatives, this study aimed at assessing the bioactivity of the ethanolic extracts of Schinus terebinthifolius (Anacardiaceae), Annona coriacea (Annonaceae), Annona crassiflora (Annonaceae), and Serjania marginata (Sapindaceae) on the life cycle of P. xylostella. Cabbage leaf discs were immersed in the treatments at a concentration of 10 mg/mL and given daily to the larvae. Larval and pupal duration and survival, pupae weight, the longevity of males and females, number and survival of eggs, incubation period, and days of oviposition parameters were evaluated. All extracts differed significantly from the control in terms of larval and pupal duration, pupal survival, and pupae weight. All the extracts prolonged the larval and pupal period of P. xylostella. Only A. coriacea did not differ significantly from the control in terms of larval survival, and the highest larval mortality was observed in the treatment with S. marginata (50%). Pupal survival, pupae mass, oviposition period, and egg survival were reduced in all treatments with ethanolic extracts. The treatments with Annona and S. marginata species have reduced the number of eggs. Treatments with S. terebinthifolius and S. marginata have reduced the incubation time of eggs. Thus, the treatments with ethanolic plant extracts act on the life cycle of P. xylostella negatively impacting the biological parameters evaluated.

乙醇提取物对小菜蛾生物学特性的影响

不加选择地使用合成杀虫剂已导致小菜蛾小菜蛾 (鳞翅目:population科)的抗性种群的出现,阻碍了对其的控制并给芸苔生产带来经济损失。因此,为了寻找替代品,本研究旨在评估中华绒螯蟹(Anacardiaceae),Annona coriacea(Annonaceae),Annona crassiflora(Annonaceae)和Serjania marginata(Sapindaceae)的乙醇提取物的生物活性。小菜蛾。将白菜叶圆片以10 mg / mL的浓度浸入处理液中,每天给幼虫服用。评估幼虫和p的持续时间和存活率,p的重量,雌雄的寿命,卵的数量和存活率,潜伏期和产卵天数。在幼虫和p的持续时间,p的存活率和p的重量方面,所有提取物均与对照显着不同。所有的提取物延长了小菜蛾的幼虫和up期。就幼虫存活而言,仅Coriacea与对照组没有显着差异,并且在边缘链球菌治疗中观察到最高的幼虫死亡率(50%)。在所有使用乙醇提取物的处理中,的存活率,mass的质量,产卵期和卵的存活率均降低。用AnnonaS.marginata种的处理减少了卵的数量。与治疗S. terebinthifoliusS.边翠具有降低的卵的孵化时间。因此,用乙醇植物提取物处理对小菜蛾的生命周期有不利影响,影响了所评估的生物学参数。
