“…'Huangjinya' is a novel chlorophyll-de cient albino cultivar that is susceptible to common pests of tea plants (e.g., E. onukii and Toxoptera aurantii) (Tian et al 2018;He et al 2023). 'Fuding white tea' is more suitable for herbivorous insects (e.g., Dendrothrips minowai, T. aurantii, and E. onukii) due to its high free amino acid content (Lu et al 2023). Although the nutritional level of plants often affects their suitability and resistance to herbivorous insects, insects search for and locate distant host plants using their sense of smell and vision in the early stages of pest infestation (Bruce et al 2005(Bruce et al , 2011.…”

Aleurocanthus spiniferus is a major pest of tea trees; both nymphs and adults suck plant sap and induce tea sooty mould. Pest occurrence varies significantly among different tea cultivars, even within the same plantation environment. It was speculated that adult A. spiniferus may be differentially attracted by different cultivars. This study aims to identify the bioactive components in tea volatiles that mediate host selection of A. spiniferus and to utilize them for effective field trapping. Through field investigations and Y-tube olfactometer tests, we identifiedtwo highly preferred tea cultivars (‘Huangjinya’ and ‘Fuding white tea’) and two cultivars (‘Baiye No. 1’ and ‘Longjing 43’) that were not. Behavioral assays and gas chromatography-mass spectrometry (GC-MS) analysis identified four attractive compounds [hexanol, (E)-2-hexenal, linalool, and (E,E)-α-farnesene] and two repellent compounds [nonanal and (Z)-3-hexenol] from tea volatiles of the four. Among these compounds, four [nonanol, (Z)-3-hexenol, linalool and (E,E)-α-farnesene] were able to elicit obvious electrophysiological (EAG) response at 100 μg/μL. In field trials, the synergistic bait trap equipped with two types of attractants, blend 4 [the mixture of linalool and (E,E)-α-farnesene] at 100 μg/μL and blend 6 [the mixture of linalool and (Z)-3-hexenol] at 100 μg/μL, had a significant attractant effect with a long effective period. Two synthetic mixtures of tea volatiles, blend 4 and blend 6, had the potential to be developed as commercial plant-based attractants for adult A. spiniferus. This study contributes to the development of sustainable, environmentally friendly management strategies for a pest that is difficult to prevent and control.

“…In tea plantations, there are observable differences in the occurrence of A. spiniferus on four tea cultivars. 'Huangjinya' and 'Fuding white tea' are more susceptible and suitable for A. spiniferus (Tian et al 2018;Lu et al 2023;He et al 2023), while 'Baiye No. 1' and 'Longjing 43' are common resistant cultivars (Liang et al 2012).…”

“…A comparison of the EPG and population parameters indicated that QC1 and QC10 exhibited strong resistance to T. aurantii, whereas HJY was susceptible to attack by T. aurantii. There have been previous reports on the resistance of different tea germplasms to T. aurantii; however, the germplasm materials used by different researchers exhibit marked variation [17,44].…”

The adaptability of phytophagous insects to different host plants is a key determinant of their population propagation. Understanding the feeding behaviour and population dynamics of insects is crucial for elucidating host adaptability and screening for insect-resistant germplasms. Here, we investigated Toxoptera aurantii (Hemiptera: Aphididae) adaptability using electropenetrography and assessed its population growth on seven tea cultivars: Huangjinya (HJY), Qianmei601 (QM601), Fudingdabaicha (FD), Longjing43 (LJ43), Qiancha1 (QC1), Qiancha8 (QC8) and Qiancha10 (QC10). The results showed that the feeding behaviour of T. aurantii differed significantly depending on the tea cultivars. The initial probing of T. aurantii on HJY was the earliest among the seven host plants. Aphids on QC1 and QC10 displayed an increased duration of stylet probing and decreased ingestion of phloem sap, whereas a contrasting trend was observed for aphids on HJY. In addition, the mechanical resistance of T. aurantii fed on HJY and QM601 during the probing phase was significantly lower than that of aphids fed on other cultivars. Population dynamic parameters revealed that the growth rate of T. aurantii reared on HJY was the fastest, and its population quantity within 15 days was markedly higher than that of aphids fed on other cultivars. These findings demonstrate that HJY is the most suitable host plant, whereas QC1 and QC10 are less suitable hosts for T. aurantii, although the aphids successfully survived on all the selected tea cultivars. Our results provide valuable information for the biological control of T. aurantii using resistant tea varieties.
