This study investigated the effect of mixing volatile organic compounds (VOC) emitted by host and non-host plants on the orientation of key pests of Brassicaceae. The study aimed to understand how these mixed VOCs influence pest behaviour, which could help in tailoring pest management strategies. The orientations of flea beetles, Phyllotreta spp., and the diamondback moth (DBM), Plutella xylostella, towards cabbage VOCs mixed with faba bean VOCs were assessed using Y-tube olfactometry. The pests' preferences were measured to determine if the presence of faba bean alongside cabbage altered their olfactory orientation compared to cabbage alone. Flea beetles showed a preference for cabbage VOCs alone over the cabbage-faba bean VOC mix. For DBM, no significant preference was observed between cabbage alone and the cabbage-faba bean mix. Previous findings indicated that faba bean attracts DBM, and in this study the mixture of cabbage and faba bean appeared to be more attractive than cabbage alone. The results indicate that faba bean VOCs can deter flea beetles from cabbage, potentially offering a pest management strategy. However, the effect on DBM was inconclusive, with no clear preference observed. This suggests that while faba bean VOCs may influence pest orientation, their effectiveness varies among different pest species. Additionally, herbivore damage to cabbage leaves did not appear to influence the odour-guided orientation of either pest, irrespective of the presence or absence of faba bean.
本研究调查了寄主植物和非寄主植物混合释放的挥发性有机化合物（VOC）对十字花科主要害虫取向的影响。研究旨在了解这些混合挥发性有机化合物如何影响害虫的行为，从而帮助制定害虫管理策略。研究采用 Y 型管嗅觉测定法评估了跳甲和钻心虫（DBM）对混合了蚕豆挥发性有机化合物的卷心菜挥发性有机化合物的取向。对害虫的偏好进行了测量，以确定与单独的卷心菜相比，蚕豆和卷心菜的存在是否会改变害虫的嗅觉取向。结果表明，蚤甲虫对卷心菜单独挥发性有机化合物的偏好高于卷心菜-蚕豆挥发性有机化合物混合物。对于 DBM 而言，单独的卷心菜与卷心菜-蚕豆混合挥发性有机化合物之间没有明显的偏好。以前的研究结果表明，蚕豆对 DBM 有吸引力，而在本研究中，卷心菜和蚕豆的混合物似乎比单独的卷心菜更有吸引力。结果表明，蚕豆挥发性有机化合物可以阻止跳甲从卷心菜上爬走，从而提供了一种潜在的害虫管理策略。然而，对 DBM 的影响并不确定，没有观察到明显的偏好。这表明，虽然蚕豆挥发性有机化合物可能会影响害虫的取向，但其效果因害虫种类而异。此外，无论是否有蚕豆，食草动物对卷心菜叶片的破坏似乎都不会影响两种害虫在气味引导下的取向。

Discontinuous hydration and dehydration (HD) cycles refer to controlled imbibition followed by dehydration before seed germination. Here, we investigated whether the level of imbibition before HD cycles affects the physiology of Tabebuia heterophylla seeds and seedlings.Seeds were imbibed for 10 h (T1; phase I of imbibition) or 35 h (T2; phase II), dehydrated, and progressively rehydrated one to four times (HD cycles). Germination and biochemical parameters (membrane integrity; total soluble, reducing, and nonreducing (NRS) sugars; proteins, amino acids, proline, H2O2, catalase, ascorbate peroxidase, and glutathione reductase activity) were quantified at the last rehydration step of each cycle. Biometric and biochemical parameters (including pigments) were analysed in seedlings 60 days after germination.HD cycles at T1 led to reduced seed germination and greater plasma membrane damage, higher enzyme activity (catalase and glutathione reductase) and accumulation of NRS, total amino acids, and proline compared to the controls and T2 treatment. Cellular damage became more severe with more HD cycles. HD cycles at T2 synchronized germination regardless of the number of cycles and also had a priming effect. T2 seeds had less NRS, total amino acids, and proline content than T1. HD cycles at T1 produced seedlings with higher carotenoid and total chlorophyll content than controls and T2, while seedlings from HD cycles at T2 had higher amounts of osmoprotectants.HD cycles at T2 benefited seeds and seedlings more than at T1. This suggests that the physiological and biochemical effects of HD cycles in seeds modulate seedling plasticity, depending on water availability, potentially promoting increased tolerance to recurrent droughts that will be intensified with ongoing climate changes.
