Data for the manuscript entitled: "Spider mites collectively avoid plants with cadmium irrespective of their frequency or the presence of competitors"

Data for the collective host choice and performance of spider mites (2023data.xlsx; adultF.xlsx; cleanpplants.xlsx; Fecnozero.xlsx): 200 Tetranychus urticae females were placed in an arena connected to the 4th leaf of 5 tomato plants. The plants were either contaminated with cadmium (3 mM) or cadmium-free and were either uninfested or infested with 100 T. evansi females. Mites were allowed to chose a host for 24 hours. After this period the number of females on each plant was registered, as well as the number of eggs laid. In the cases where there were plants infested with T. evansi the leaves were collected and kept for 14 days until the following generation of adul females of each specias was counted.Data for the individual choice of T. urticae (Habitat_Choice_G14_SR1.xlsx): T. urticae females were placed in a plastic strip connecting two plant leaf discs, one made from the 3rd or 4th leaf of one cadmium-free plant and the other made from the 3rd or 4th leaf of plant with cadmium (2 mM). Mites were allowed to chose a leaf disc for 24 hours. After this period the choice of each female was registered, as well as the number of eggs laid on each leaf disc.Data for the individual performance of T. urticae (Habitat_Choice_G14_SR1.xlsx): T. urticae females were placed in leaf disc made from the 3rd or 4th leaf of either a cadmium-free plant or plant with cadmium (2 mM). Mites were allowed to lay eggs for 48 hours. After this period the number of eggs laid on each leaf disc.Each excel file has a read me sheet including the information needed to interpret the data sheet.

二斑叶螨（Tetranychus urticae）集体寄主选择与繁殖性能数据集（配套数据文件：2023data.xlsx、adultF.xlsx、cleanpplants.xlsx、Fecnozero.xlsx）：将200头二斑叶螨雌成螨接入连接5株番茄第4片叶的行为试验区域中。供试番茄植株分为镉污染组（镉浓度3 mM）与无镉对照组两类，每类植株又分别设置未接虫与接虫两个亚组，其中接虫组接入100头埃氏叶螨（Tetranychus evansi）雌成螨。允许叶螨在24小时内自主选择寄主，试验结束后记录每株番茄上的雌成螨数量与产卵量。对于接有埃氏叶螨的植株，采集其叶片并保存14天，随后统计两代各物种的雌成螨数量。
二斑叶螨个体寄主选择数据集（配套数据文件：Habitat_Choice_G14_SR1.xlsx）：将单头二斑叶螨雌成螨置于连接两组叶碟的塑料条上，其中一组叶碟取自无镉番茄植株的第3或第4片叶，另一组取自镉浓度为2 mM的番茄植株的第3或第4片叶。允许叶螨在24小时内自主选择叶碟，试验结束后记录每头雌成螨的选择结果，以及两组叶碟上的产卵量。
二斑叶螨个体繁殖性能数据集（配套数据文件：Habitat_Choice_G14_SR1.xlsx）：将单头二斑叶螨雌成螨置于取自无镉或镉浓度为2 mM的番茄植株第3或第4片叶的叶碟上，允许叶螨产卵48小时，试验结束后记录每片叶碟上的产卵量。
